DESCRIPTION
Emulsions comprising a PEG derivative of tocopherol
Field of the invention
Compositions and methods are provided for preparing foods and beverages that contain additives, such as nutraceuticals, pharmaceuticals, and supplements.
Background
Nonpolar compounds do not dissolve easily in aqueous solutions, such as water or any other polar solvent. A number of nonpolar compounds are used in compositions for human ingestion, eg, pharmaceuticals, nutraceuticals, and / or dietary supplements. Exemplary of the nonpolar compounds used in such compositions are vitamins and minerals, fatty acids and other nonpolar compounds, nonpolar active agents and nonpolar active ingredients.
Document US2006 / 0088558 describes a composition of Vitamin E concentrate and liquid TPGS, the concentrate having a significantly higher percentage of TPGS per unit volume than traditional liquid TPGS formulations while providing the TPGS in a liquid form that can be used in gels. soft or mixed with water to produce desired concentrations for commercial use in supplements, beverages, pharmaceutical preparations etc.
WO96 / 36316 describes self-emulsifying pharmaceutical pre-concentrate compositions comprising: (a) a lipophilic medicinal compound, (b) d-alpha-tocopherol polyethylene glycol 1000 succinate (TPGS) and (c) a lipophilic phase as well as pharmaceutical compositions which They comprise such pre-concentrates in combination with a sufficient quantity of water to produce a stable emulsion.
US2005 / 208082 describes an aqueous emulsion in which the liquid phase of the emulsion includes a combination of a therapeutically effective concentration of a lipophilic such as a concentration of Vitamin E and TPGS and a concentration of linoleic acid. The presence of linoleic acid increases the solubilizing effect of Vitamin E and TPGS in the lipophilic and thus reduces the amount of Vitamin E and TPGS that would otherwise be required in the aqueous emulsion.
Due to poor water solubility, the inclusion of nonpolar compounds in products for human consumption, eg supplements, food and beverages, is often a challenge. Available compositions containing nonpolar compounds, particularly aqueous compositions containing nonpolar compounds, and methods for formulating such compositions are limited. Thus, there remains a need to develop compositions containing nonpolar compounds and methods for preparing the compositions. Accordingly, it is among the objects of this document to provide compositions, including aqueous compositions, containing nonpolar compounds and methods for preparing the compositions.

Methods for preparing the concentrates and methods for preparing the liquid dilution compositions are also described. Generally, the methods for preparing the concentrates are performed by separately generating an oil phase and an aqueous phase, and mixing the two phases, typically by emulsion, to form the concentrate, which is a liquid nanoemulsion concentrate. The oil phase ingredients are added to form the oil phase and the aqueous phase ingredients are added to form the water phase. The ingredients are selected from the ingredients of the concentrates, as described herein, which typically include a nonpolar compound, a surfactant, and a polar solvent, as described herein. Typically, the oil phase ingredients include the nonpolar compound (s), typically a nonpolar active ingredient (s) of the concentrate, and the aqueous phase ingredients include the polar solvent. Ingredients are added in amounts within the appropriate concentration range to provide concentrates as described herein. In one example, the ingredients of the aqueous phase include the surfactant. In another example, the oil phase ingredients contain the surfactant. In one example, the aqueous phase ingredients and the oil phase ingredients contain the surfactant.
The amounts of the surfactant (s), the non-polar active ingredient (s), and the polar solvent are selected based on the appropriate concentration ranges of these ingredients in the resulting concentrate. For example, the non-polar active ingredient is included in an amount between 5% or about 5% and 10% or about 10% by weight (w / w) of the final concentrate; the surfactant is included in an amount that is between 16% or about 16% and 30% or about 30% by weight (w / w) of the final concentrate; and the polar solvent is included in an amount that is between 60% or about 60% and 79% or about 79% by weight (w / w) of the final concentrate as described above.
In one example, the oil phase ingredients additionally include the non-polar solvent (s). In one example, the concentrate is prepared with first and second oil phase ingredients and the first oil phase ingredient includes the nonpolar active ingredient and the solvent. In one example, the solvent contains an oil, other than the non-polar active ingredient, such as, for example, Vitamin E, linseed oil, and / or safflower oil.
In one example, the oil phase ingredients and / or the aqueous phase ingredients contain the co-surfactant in an amount sufficient to stabilize the concentrate, such as a phospholipid, eg, phosphatidylcholine. In one example, the amount of phospholipids is between 0.1% or about 0.1% and 1% or about 1% by weight (w / w) of the concentrate. In another example, the oil phase ingredients and / or the water phase ingredients additionally contain at least one preservative in an amount sufficient to preserve the concentrate, such as, for example, a preservative containing benzyl alcohol. In one example, the amount of the preservative and / or benzyl alcohol is between 0.1% or about 0.1% and 1% or about 1% by weight (w / w) of the concentrate.
In another example, the oil phase ingredients and / or the water phase ingredients additionally contain an emulsion stabilizer, in an amount sufficient to stabilize the concentrate, such as an emulsion stabilizer containing a combination of gums, such as any one or more of guar gum, xanthan gum, and sodium alginate.
In an exemplary method of making the concentrate, an oil phase is generated by mixing the oil phase ingredients in a first container and heating the oil phase ingredients; an aqueous phase is generated by mixing one or more aqueous phase ingredients in a second container and heating the aqueous phase ingredients; and the oil and water phases are emulsified to generate the concentrate.
In another exemplary method provided, an oil phase is generated by mixing one or more first oil phase ingredients in the first container and heating the first oil phase ingredients at least until the first oil phase ingredients dissolve; then one or more additional ingredients of the oil phase are added to the first container; and mixing and heating the first ingredient and additional ingredients of the oil phase; an aqueous phase is generated by mixing one or more aqueous phase ingredients in a second container and heating the aqueous phase ingredient (s); and the aqueous and oily phases are emulsified, to generate the concentrate.
Heating and mixing of the water and oil phases can be done simultaneously or sequentially, in any order.
In any of the methods for preparing the concentrates, the mixing steps (for example, mixing the oil and / or aqueous phases) can be carried out with a conventional mixer, such as any of the conventional mixers indicated in this document, or with any another mixer described in this
ES 2 396 946 T3 document, such as with a homogenizer. In any of the methods provided, heating can be accomplished using one or more heating devices such as, for example, a hot plate, a water jacket, or any of the heating devices indicated herein. In one example, the oil phase ingredients are heated with a first heating apparatus and the aqueous phase ingredients are heated with a second heating apparatus. In one example, heating involves heating the ingredients to 60 ° C or about 60 ° C, or to about 70 ° C, or to or about 71 ° C. In one example, the oil phase and / or aqueous phase ingredients are heated between about 45 ° C or about 45 ° C and between about 85 ° C or about 85 ° C, for example; year approximately 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68 , 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84 or 85 ° C.
In either method, the emulsifier can be made using a homogenizer, such as any homogenizer described herein. In one example, the emulsification is performed between 850 rpm or about 850 rpm and 1200 rpm or about 1200 rpm. In another example, it is done at or about 30 rpm.
In some examples, the methods further include rapidly cooling the emulsion being formed during the emulsifying step. In some examples, quenching results in the cooling of the emulsion being formed between 25 ° C or about 25 ° C and 43 ° C or about 43 ° C, such as 25, 26, 27, 28. , 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42 or at 44 ° C, for example, between at or about 25 ° C and at or at about 35 ° C, or between at or about 35 ° C and at or at about 43 ° C. In one example, cooling the emulsion results in less than or about 60 minutes, less than or about 30 minutes, or between or about 30 and in or about 60 minutes. Exemplary means for performing rapid cooling include repeatedly passing the phases through a cooling apparatus attached to a container.
The methods may further include adding one or more flavorings (eg lemon oil, D-limonene) and / or one or more pH adjusters (eg citric acid, phosphoric acid) to the concentrate, eg after emulsifying. the oil and water phases. The pH is typically measured simultaneously with, before and / or after the addition of the pH adjuster, and the amount of the pH adjuster is determined by the pH of the concentrate. Typically, the pH adjuster comprises an acid or a base in an amount sufficient to affect the pH of the concentrate.
In one example of the methods, the ingredients are added to the container (s) simultaneously or sequentially, in any order. In another example, the ingredients (for example, the oil phase and / or water phase ingredients) are added to the containers in a particular order, such as the specific order provided herein, for example, in the examples. individual provided. In one example, where the aqueous phase ingredients contain a polar solvent (for example, water, propylene glycol, glycerin, or another diol such as another sugar alcohol) and an emulsion stabilizer, the aqueous phase ingredients are added sequentially in The following order: 1) polar solvent (eg, water, propylene glycol, or glycerin); 2) emulsion stabilizer. In another example, where the oil phase ingredients contain the surfactant, the nonpolar compound, and a preservative, the oil phase ingredients are added sequentially, in the following order: 1) surfactant, 2) preservative; 3) non-polar compound (ie, non-polar active ingredient). In another example, where the oil phase ingredients contain the surfactant, the nonpolar compound, a preservative, and an emulsion stabilizer, the oil phase ingredients are added to the oil phase container sequentially, in the following order : 1) surfactant, 2) preservative; 3) nonpolar compound; and 4) emulsion stabilizer. In another example, where the oil phase ingredients contain the surfactant, the nonpolar compound, a preservative, a solvent, and an emulsion stabilizer, the oil phase ingredients are added to the oil phase container sequentially, in the following order : 1) surfactant, 2) preservative; 3) non-polar solvent; 4) nonpolar compound; and 5) emulsion stabilizer. In another example, where the oil phase ingredients contain the surfactant, the nonpolar compound, a preservative, a nonpolar solvent, a cosurfactant, and an emulsion stabilizer, the oil phase ingredients are added to the container of the oil phase sequentially, in the following order: 1) surfactant, 2) preservative; 3) non-polar solvent; 4) co-surfactant; 5) non-polar compound and 6) emulsion stabilizer. In another example, where the aqueous phase contains a polar solvent and a surfactant, the polar solvent and the surfactant are added sequentially in this order. In another example, where the oil phase contains a nonpolar solvent, a preservative, a cosurfactant, a surfactant, and a nonpolar compound, the nonpolar solvent, the preservative, and the cosurfactant are added and mixed until dissolved. the cosurfactant; the surfactant is added until it dissolves; and the non-polar active ingredient is added, in that order.
In one example, the methods for producing the concentrates are performed using experimental scale processes, as provided herein. In another example, particularly with large batches of the concentrates, the methods are performed with a large-scale process, as described later in this document, such as the exemplary large-scale processes illustrated in Figure 1.
In one example, where the polar solvent is water, the water is purified first by passing it through purifiers. In one example, water purification is done by passing it through purifiers,
ES 2 396 946 T3 sequentially, in the following order: a carbon filter, an ion exchange kit, a reverse osmosis kit, a 100 micron end-point filter, and a 50-micron point-of-use filter. In this example, after purification, the water is added with the other ingredients of the aqueous phase to an aqueous phase tank. The ingredient (s) of the aqueous phase are then mixed using a conventional mixer attached to the tank, for example, mounted on top of the tank. A heating apparatus (typically the water jacket in the aqueous phase tank) is used to heat the aqueous phase ingredients during the generation of the aqueous phase, typically at low heat (eg 60 ° C). To generate the oil phase, the oil phase ingredient (s) are weighed / measured and added to an oil phase tank. The oil phase ingredients are mixed using a conventional mixer attached to the oil phase tank, eg tank mounted. A heating apparatus (typically the water jacket in the oil phase tank) is used to heat the oil phase ingredients during generation of the water phase, typically at low heat (eg 60 ° C). Once the oil and water phases reach 60 ° C, and after the oil phase components have dissolved, the oil and water phases are combined by transferring the oil phase to the water phase container, through a medium of transfer. For this process, a homogenizer mounted on the aqueous phase tank is turned on, for example, at 850-1200 rpm. The ball valves are then opened and the transfer pump is switched on, thereby effecting the transfer of the liquid oil phase to the water phase tank through the transfer tube or tubes. As the phases combine, the mixture is homogenized by continuous mixing with the homogenizer. The homogenizer can be adjusted, for example, by adjusting the baffle plate in the homogenizer to achieve and maintain an emulsion, for example, by moving the baffle plate further during emulsion formation and / or further out of the forming emulsion. During the emulsion stage, the forming emulsion is cooled, typically rapidly cooled, by repeatedly passing the forming emulsion through a recirculating cooler, which is attached to the aqueous phase tank. The emulsion is transferred, via transfer medium to a containment / packaging tank, where additional ingredients can be added and / or the mixture can be evaluated. The additional ingredients are mixed into the concentrate using a conventional mixer. A final product filter is used to filter the concentrate before use.
Any of the methods of producing the concentrates can be used to prepare any of the provided concentrates, as described herein.
Methods for producing the liquid dilution compositions containing the concentrates, such as beverages containing the concentrates, are also described. These methods include methods of providing oil-based additives, for example, in a food or beverage. These methods include adding any of the provided concentrates, eg, liquid nanoemulsion concentrates, to an aqueous medium, such as a beverage. Typically, the concentrate is added to the medium eg, beverage such that the medium contains an effective amount of the additive (eg, the non-polar active ingredient).
The effective amount of the additive, such as the non-polar active ingredient, is the amount and / or concentration of the additive necessary to prevent, cure, ameliorate, arrest, or partially arrest a symptom of a disease or disorder or the amount and / or concentration desired to the intake of an individual such as daily intake and / or nutritional supplement, for example, an amount sufficient to enhance the nutritional, pharmaceutical, nutraceutical, health or energy properties of a food, beverage or other consumable product. In some examples, the concentrate is added to the aqueous medium such that the resulting dilution liquid composition contains an effective amount of a particular nonpolar compound, for example, a particular amount by volume or weight of the composition such as, for example, less 25 mg or about 25 mg, at least 35 mg or about 35 mg, at least 50 mg or about 50 mg or at least 100 mg or about 100 mg, at least 250 mg or about 250 mg, or at least 500 mg or about 500 mg of the non-polar active ingredient per 8 fluid ounces (0.236588 liters) of the liquid dilution composition.
In one example, an effective amount is a concentration or amount of the liquid nanoemulsion where at least 25 mg or about 25 mg, typically at least 35 mg, for example, 35, 40, 45, 50, 55, 60, 65, 70 , 75, 80, 85, 90, 95, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240, 250, 260, 270, 280, 290 , 300, 325, 350, 375, 400, 425, 450, 475, 500, 550, 600, 700, 800, 900 1000, 1500, 2000 mg, or more of the nonpolar active ingredient is contained in at least 8 fluid ounces (0.236588 liters) of the aqueous medium.

In the illustrated example the ingredient (s) of the aqueous phase are then mixed using a conventional mixer 111 attached to the tank, eg mounted on top of the tank. A heating apparatus (typically the water jacket in the aqueous phase tank) is used to heat the aqueous phase ingredients during aqueous phase generation, typically at low heat (eg 60 ° C). To generate the oil phase, the oil phase ingredient (s) are weighed / measured and added to the oil phase tank 102. The oil phase ingredients are mixed using a conventional mixer 111 attached to the oil phase tank, eg tank mounted. A heating apparatus (typically the water jacket in the oil phase tank) is used to heat the oil phase ingredients during generation of the water phase, typically at low heat (eg 60 ° C).

As used herein, "surfactant and surface active agent" refer synonymously to amphiphilic molecules of synthetic and natural origin having hydrophobic portion (s) and hydrophilic portion (s). Due to their amphiphilic (amphipathic) nature, surfactants and co-surfactants can typically reduce the surface tension between two immiscible liquids, eg, the oil and water phases in an emulsion, stabilizing the emulsion. Different surfactants can be characterized on the basis of their relative hydrophobicity and / or hydrophilicity. For example, relatively lipophilic surfactants are more soluble in fats, oils, and waxes, typically having HLB values less than 10 or about 10, while relatively hydrophilic surfactants are more soluble in aqueous compositions, for example, water and typically have HLB values. HLBs older than 10 or about 10. Relatively amphiphilic surfactants are soluble in oil- and water-based liquids and typically have HLB values near 10 or about 10.
Surfactants include, for example, soaps, detergents, lipids, emulsifiers, dispersing agents and wetting agents, molecules that emulsify liquids, for example, by forming an emulsion in an aqueous medium, or a diluting aqueous liquid composition, for example, by forming a dispersion colloidal of two immiscible liquids in the form of drops, for example, an emulsion such as a microemulsion; and compounds that form various macromolecular structures, eg, aggregates, in liquids, eg, micelles, liquid bilayer structures, including liposomes and reverse micelles.

Alternatively, the analog may have similar or identical chemical or physical properties compared to the parent compound and / or may have similar or identical biological and / or chemical activity. For example, the analog may be more hydrophilic or may have altered reactivity compared to the parent compound. The analog may be mimetic with the chemical and / or biological activity of the parent compound (ie, it may have similar or identical activity) or, in some cases, it may have greater or lesser activity. The analog can be of natural or non-natural origin (eg synthetic) which is a variant of the parent compound. Other types of analogs include isomers (eg, enantiomers, diastereomers) and other types of chiral variants of a compound as well as structural isomers. The analog can be a branched or cyclic variant of a linear compound. For example, a linear compound may have an analog that is branched or otherwise substituted to confer certain desirable properties (eg, improve hydrophobicity or bioavailability).

As used herein, TPGS-1000 homologs are analogs of TPGS-1000 that differ from the parent compound TPGS-1000 only by the presence or absence of a single unit such as a methylene unit, or some multiple of such units. , for example, - (CH2) n-. Suitable TPGS-1000 homologues have similar surfactant properties compared to the parent compound (TPGS-1000), eg, similar HLB values, eg, HLB values between 14 or about 14 and 20 or about 20. Homologs Suitable TPGS-1000s include homologs of TPGS-1000 with slight variations in the chain length of the PEG moiety, and me-TPGS-1000, which is a TPGS-1000 that has a methyl end on the PEG moiety.
As used herein, HLB refers to a value that is used to index and describe a surfactant according to its relative hydrophobicity / hydrophilicity, relative to other surfactants. An HLB value of the surfactant is an indication of the molecular balance of the hydrophobic and lipophilic portions of the surfactant, which is an amphipathic molecule. Each surfactant and surfactant mixture (and / or co-surfactants) have an HLB value which is a numerical representation of the relative weight percent of the hydrophobic and hydrophilic portions of the surfactant molecule (s). The HLB values are derived from a semi-empirical formula. The relative weight percentages of the hydrophobic and hydrophilic groups are indicative of surfactant properties, including molecular structure, eg, the types of aggregates that the surfactant will form, and the solubility of the surfactant. See, for example, Griffin, WCJ Soc. Cos. Chem. 1: 311 (1949).
HLB values for surfactant range from 1-45, while the range for nonionic surfactants is typically 1-20. A surfactant is more lipophilic the lower its HLB value. Conversely, the more hydrophilic a surfactant is, the higher its HLB value. Lipophilic surfactants have higher solubility in oil and lipophilic substances, while hydrophilic surfactants dissolve more easily in aqueous media. In general, surfactants with HLB values greater than 10 or greater than about 10 are called hydrophilic surfactants, while surfactants having HLB values less than 10 or less than about 10 are called hydrophobic surfactants. HLB values have been determined and are available for a plurality of surfactants (see, for example, US Patent No. 6,267,985). It should be appreciated that the HLB values for a given surfactant or co-surfactant can vary, depending on the empirical method used to determine the value. Thus, the HLB values of surfactants and cosurfactants provide a rough guide for formulating compositions based on relative hydrophobicity / hydrophilicity. For example, a surfactant is typically selected from surfactants that have HLB values within
ES 2 396 946 T3 of a particular range of surfactant or co-surfactant that can be used for guide formulations. The
Table 1A shows HLB values of exemplary surfactants and co-surfactants.

The surfactants and HLB values set forth in Table 1A are exemplary. Any known surfactant or cosurfactant can be used with the provided compositions (see, for example, US Patent No. 6,267,985). The surfactant (s) contained in the compositions provided typically have an HLB value between 14 or about 14 and 20 or about 20, eg, 14 or about 14, 15 or about 15, 16 or about 16, 17 or about 17, 18 or about 18, 19 or about 19 and 20 or about 20.
As used herein, the term "micelle" refers to aggregates formed by surfactants that typically form when the surfactant is present in an aqueous composition, typically when the surfactant is used at a concentration above the critical micelle concentration (CMC). . In micelles, the hydrophilic portions of the surfactant molecules come into contact with the aqueous phase or water, while the hydrophobic portions form the core of the micelle, which can encapsulate the non-polar ingredient (s), for example, the compounds nonpolar in the compositions provided. Typically, the surfactants in the provided compositions form micelles containing the nonpolar ingredient at their center in aqueous liquid dilution compositions. Typically, the micelles in the compositions provided have a particle size of about 1000 nm, typically less than 500 nm or less than about 500 nm, typically less than 300 or about 300 nm, for example, less than 250 nm or about 250 nm. , for example, less than 200 nm or less than about 200 nm, for example, less than or less than about 5, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190 or 200 nm.
As used herein, reverse micelles are surfactant aggregates that are typically formed in lipophilic solution, with the hydrophilic portions forming the core. When the cross-sectional area of the hydrophobic region of the surfactant molecule is greater than that of the hydrophilic part of the molecule, the formation of micelles, which can be hexagonal phase structures, is favored.
As used herein, liposomes are surfactant aggregates composed of lipid bilayers, typically having an aqueous core. Liposomes are typically formed by lipid surfactants, typically phospholipids, which are phosphate-containing amphipathic lipids, eg, molecules containing a phosphate, a glycerol, and one or more fatty acids and similar surfactants. Alternatively, phospholipid surfactants can be used as co-surfactants, which can be incorporated into aggregates of other surfactant or surfactants, eg, micelles. Lipid bilayers are two-dimensional sheets in which all hydrophobic portions, eg, acyl side chains, are protected from interaction with an aqueous liquid, except those at the ends of the sheet. An energetically unfavorable interaction of the acyl chains with water results in the folding of the bilayers to form liposomes, three-dimensional lipid bilayer vesicles. In the example, the liposome is formed as a single bilayer that encloses a single aqueous space (small unilamellar vesicles; SUVS). In another example, the liposome is composed of concentric bilayers with many aqueous spaces that alternate with the bilayers (multilamellar vesicles; MLVS). Liposomes that can be used to encapsulate hydrophobic and hydrophilic active ingredients. In liposomes, the non-polar active ingredients are typically divided between the bilayers while the hydrophilic active ingredients are typically trapped within the aqueous compartments. In the example, liposomes can be advantageous as transport / encapsulation systems because they are stable and can protect the active ingredients from degradation, for example, by oxygen and digestive enzymes.
As used herein, co-surfactant is used to refer to a surfactant, typically a phospholipid, which is used in the compositions provided, in combination with a surfactant (eg, a major surfactant) for example, to improve the emulsifying the provided compositions and / or compounds, for example to emulsify the ingredients. In one example, the compositions provided contain at least one surfactant and at least one co-surfactant. Typically, the cosurfactant is a lipid, eg, a phospholipid, eg, phosphatidylcholine. In one example, the cosurfactant has an HLB value between 7 or about 7 and 8 or about 8. Typically the cosurfactant represents a lower percentage by weight (w / w) of the compositions provided, compared to the surfactant. . Thus, the compositions provided typically have a lower concentration of the cosurfactant (s) than the surfactant.
As used herein, a phospholipid is a phosphate-containing amphipathic lipid, eg, a molecule containing a phosphate, a glycerol, and one or more fatty acids. In one example, one or more phospholipids are used as a co-surfactant in the compositions provided. Exemplary phospholipids used in the compositions provided are lecithin, including phosphatidylcholine (PC), phosphatidylethanolamine (PE), distearoylphosphatidylcholine (DSPC), phosphatidylserine (PS), phosphatidylglycerol (PG), phosphatidic acid (PA), phosphatidyl acid (PA), phosphatidyl choline (PI). SPM) or a combination thereof. Typically, the phospholipid is phosphatidylcholine (PC), which is sometimes referred to by the general name lecithin. Exemplary of the phospholipids that can be used as co-surfactants in the provided compositions are the phospholipids marketed by Lipoid, LLC, Newark, NJ, for example, Purified Egg Lecithins, Purified Soybean Lecithins, Egg Lecithins, and Soybean Seed. Hydrogenated, Egg Phospholipids, Soy Seed Phospholipids, Hydrogenated Egg

Exemplary of the phosphatidylcholine that is used as a co-surfactant in the compositions provided is the phosphatidylcholine composition sold by Lipoid, LLC, under the name
Lipoid S100, which is obtained from soybean extract and contains more than 95% or more of approximately the

Micelles containing the nonpolar compounds typically have a small or relatively small particle size, for example, less than 1000 nm or about 1000 nm, less than 500 nm or about 500 nm, typically less than 300 nm or about 300 nm, typically less than 200 nm or about 200 nm, for example 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 , 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 125, 150 or 200 nm. A smaller particle size is correlated with the transparency of the aqueous liquid dilution compositions containing the dilute concentrates. For example, a liquid with a smaller particle size is more transparent than a liquid with a larger particle size. The smaller particle size can also contribute to other desirable properties, eg, stability.
A number of factors, including ingredients, their relative concentrations, and methods for preparing the concentrates, affect the particle size of the compositions and other desirable properties of the compositions, such as transparency. In particular, the nature of the surfactant, particularly the HLB of the surfactant, and the relative concentrations of the polar solvent (eg, water), surfactant, and the nonpolar compound, contribute to the small particle size in the transparency of aqueous dilution liquid compositions. . Typically, several of these parameters and properties are related to each other. For example, several of the parameters contribute to particle size, typically a small particle size of the compositions. Particle size contributes directly to the transparency of aqueous dilution liquid compositions containing concentrates. The particle size may also be related to other properties, for example, stability, absence of ring formation and / or formation of a precipitate of the aqueous liquid dilution compositions containing the concentrates.
Consequently, the properties of the ingredients and their relative concentrations in the concentrates are important to the ability of the concentrate to produce desirable dilution compositions. Methods are provided for formulating the liquid nanoemulsion concentrates. Determination of the appropriate ingredients, and the relative concentrations thereof, that will produce dilution compositions having desirable properties, is accomplished using the methods provided for formulating the liquid concentrates.

to. Formulation of liquid concentrates
In the provided formulation methods, concentrates are formulated by selecting the ingredients and the concentration ratios of the ingredients that produce compositions having one or more desired properties. When the concentrates are formulated, the selected ingredients and starting concentrations are used to prepare the initial concentrates, which are evaluated and modified, if necessary.
In a first step in formulating the provided concentrates, one or more of the initial concentrates are prepared and evaluated for the desired properties. For this step, ingredients are selected, for example, from the ingredients described in this document. The ingredients generally include surfactants, polar solvents, non-polar active ingredients, and other ingredients. A starting concentration (weight percent) of each selected ingredient is selected within the appropriate concentration range for that ingredient or category of ingredient, eg, the appropriate concentration range for the surfactant. In some cases, the initial concentrate is formulated based on the ingredients and concentrations thereof in an existing concentrate that has one or more desired properties.
The starting concentrate or concentrates are then prepared, using the concentrate preparation methods provided below, adding each ingredient to its starting concentration in the appropriate step. In one example, more than one starter concentrate, eg, multiple starter concentrates, each of which has a different concentration of one or more ingredients, are prepared and compared. In one example, multiple initial concentrates are produced to test various representative concentrations within an appropriate concentration range for one or more particular ingredients.
In a typical example, the initial concentrate is prepared by including at least one surfactant, such as among the surfactants described herein, having an HLB value between 14 or about 14 and 20 or about 20, at a starting concentration within the concentration range of between 16% or about 16% and 30% or about 30% by weight (w / w) of the concentrate; at least one non-polar compound, at a starting concentration within the concentration range of between 5% or about 5% and 10% or about 10%; and a polar solvent at a starting concentration of between 60% or about 60% and 80% or about 80% and typically between me and about 60% and or about 79% by weight. In one example the initial concentrate further includes other ingredients, eg, a preservative (s), co-surfactant (s), and / or other ingredients as described herein.
After preparing the initial concentrate (s), the concentrate (s) are evaluated for one or more desired properties, for example, the ability to form dilution compositions (eg, clear dilution compositions or dilution compositions that have a haze value). particle size, or other property). The ability to form dilution compositions having one or more properties is evaluated by diluting the concentrate in an aqueous medium, for example, diluting the concentrate in the aqueous medium at a dilution factor of between 1:10 or about 1:10 and 1 : 1000 or about 1: 1000 or greater, typically between 1:10 or about 1:10 and 1: 500 or about 1: 500 or greater, for example, does not dilute more than 1:10 or about 1:10, 1 : 20 or about 1:20, 1:25 or about 1:25, 1:50 or about 1:50, 1: 100 or about 1: 100, 1: 200 or about 1: 200, 1: 250 or about 1: 250, 1: 300 or about 1: 300, .1: 400 or about 1: 400, 1: 500 or about 1: 500, for example, 1:10, 1:20, 1:25, 1:30, 1:35, 1:40, 1:50, 1:55, 1:60, 1:65, 1:70, 1:75, 1:80, 1:90, 1: 100, 1: 110, 1: 120, 1: 130, 1: 140, 1: 150, 1: 160, 1: 170, 1: 180, 1: 190, 1: 200, 1: 210, 1: 220, 1: 230, 1: 235, 1: 240, 1: 250, 1: 260, 1: 270, 1: 280, 1: 290, 1: 300, 1: 350, 1: 400, 1: 450, 1: 500 or greater, or according to other dilutions provided in this document.
After evaluation, the ingredients and / or concentrations thereof can be adjusted to generate the desired properties in the final concentrate. Typically, the concentration of the non-polar compound, surfactant, and / or polar solvent is the concentration that is adjusted after evaluating the initial concentrate. Similarly, when multiple initial concentrates are formulated, one or more of the nonpolar compound, surfactant, and polar solvent concentration are varied among the multiple initial concentrates. In some cases, after evaluation, it may be determined that additional ingredients (not included in the initial formulation) are necessary or desirable to achieve the desired properties of a particular concentrate. This process can be repeated until a concentrate is generated that has the desired property (s).
i. Common Ingredients and Typical Concentration Ranges
Each of the concentrates provided contains a nonpolar compound such as, but not limited to, the exemplary nonpolar compounds described herein below. Typically, the non-polar compound is a non-polar active ingredient, for example, an oil-based active ingredient such as a polyunsaturated fatty acid (PUFA), a coenzyme Q, or a phytochemical. To formulate the initial concentrate, the starting concentration of the nonpolar compound is typically a concentration chosen from within a concentration range of between 5% or about 5% and 10% or about 10% (w / w) of the concentrate, such as a
ES 2 396 946 T3 starting concentration of 5% or about 5%, 6% or about 6%, 7% or about 7%, 8% or about 8%, 9% or about 9% or 10% or about 10% (w / w) of the concentrate. The nonpolar compound is typically added as part of an oil phase, according to the methods provided to prepare the concentrate.

about 28%, 29% or about 29% or 30% or about 30% by weight (w / w) of the concentrate, such as, for example, 17.75%, 20.25%, 20.5%, 22.7% or 25.2% (w / w) of the concentrate.
In one example, the concentration range of the surfactant is between 16% or about 16% and 26% or about 26% by weight (w / w) of the concentrate, such as, for example, between 17% or about 17% and 25% or about 25% (w / w) of the concentrate; between 18% or about 18% and 26% or about 26% (w / w) of the concentrate; between 16% or about 16% and 18% or about 18% (w / w) of the concentrate; such as for example 18% or about 18% (w / w) of the concentrate, 20% or about 20% (w / w) of the concentrate, 23% or about 23% (w / w) of the concentrate, or 25% or about 25% (w / w) of the concentrate. In another example, the surfactant concentration range is between 17% or about 17% and 26% or about 26% (w / w) of the concentrate.

One or more, typically more than one additional ingredient can be added to the initial concentrate. For example, concentrates typically contain at least one preservative, typically a natural preservative, eg, benzyl alcohol. Exemplary are other additional ingredients that can be added to concentrates, including emulsion stabilizing starting concentrates, eg, a combination of gums; a non-polar solvent for the non-polar compound, eg, an oil other than the non-polar compound, eg, a vitamin E oil or linseed oil; a pH adjuster, for example citric acid, phosphoric acid; one or more flavoring agents, for example, D-limonene or lemon oil; a co-surfactant, eg, a phospholipid, eg, phosphatidylcholine.
Appropriate concentration ranges for additional ingredients are described in the individual sections below. Typically, the concentration of additional ingredients depends, in part, on the
ES 2 396 946 T3 concentrations of the non-polar active ingredient, the surfactant and the polar solvent. Typically, the concentrations of these three ingredients (surfactant, polar solvent, and nonpolar compound) are focused on the formulation methods. For example, when it is determined that modifications should be made to ingredient concentrations in the initial concentrate, typically it is the concentrations of one or more of these three ingredients that are adjusted.
In one example, it may be desirable to add one or more of the additional ingredients after evaluation of the initial concentrate, for example, to improve the concentrate with respect to one or more desired properties.
ii. Initial concentrate evaluation
Formulation methods further include analysis of the initial concentrate based on one or more desired properties, eg, properties of an aqueous dilution liquid composition containing the dilute concentrate, eg, transparency, color, odor, taste, safety, stability, ring formation or formation of precipitates and / or the presence of crystals. For example, the methods typically include analyzing the initial concentrate's ability to form a clear liquid upon dilution in an aqueous medium, such as by analyzing the transparency / turbidity of the resulting dilution aqueous liquid composition containing the initial concentrate.
For evaluation of the properties of the aqueous liquid dilution composition, the initial concentrate is diluted in an aqueous medium, typically water or other polar solvent, for example, at a dilution factor of between 1:10 or about 1:10 and 1: 1000 or about 1: 1000, typically between 1:10 or about 1:10 and 1: 500 or about 1: 500, for example, no more than 1:10 or about 1:10 diluted, at least 1 : 20 or about 1:20, at least 1:25 or about 1:25, at least 1:50 or about 1:50, at least 1: 100 or about 1: 100, at least 1: 200 or about 1: 200, at least 1: 250 or about 1: 250, at least 1: 300, at least 1: 400 or at least 1: 500, for example, 1:10, 1:20, 1:25, 1:30, 1:35, 1:40, 1:50, 1:55, 1:60, 1:65, 1:70, 1:75, 1:80, 1:90, 1: 100, 1: 110, 1: 120, 1: 130, 1: 140, 1: 150, 1: 160, 1: 170, 1: 180, 1: 190, 1: 200, 1: 210, 1: 220, 1: 230, 1: 235, 1: 240, 1: 250, 1: 260, 1: 270, 1: 280, 1: 290, 1: 300, 1: 350, 1: 400, 1: 450, 1: 500, or any other dilution, such as others provided herein. Typically, the transparency of the aqueous liquid dilution composition containing the initial diluted concentrate is evaluated using one or more approaches. Additionally, other properties can be evaluated, for example odor and / or taste properties of the liquid, for example, when the nonpolar compound is a polyunsaturated fatty acid (PUFA), particularly fish oil or seaweed oil, if a liquid composition Aqueous fish-smelling dilution can be empirically evaluated.
(1) Transparency
In one example, dilution of the provided concentrates in aqueous medium produces clear liquids. The transparency of the aqueous dilution liquid composition containing the initial concentrate can be evaluated by one or more of a plurality of approaches, such as by empirical observation, measuring the particle size and / or measuring the haze value of the liquid.

In another example, the clear liquid is formed in less dilute 1:10 dilutions of the concentrate.
The liquid nanoemulsion concentrates provided can be formulated using any non-polar compound for dilution in an aqueous medium. In one example, concentrates can be diluted in aqueous medium, for example, over a wide dilution range to form clear liquids, for example, at a dilution factor between 1:10 or about 1:10 and 1: 1000 or about 1 : 1000, typically between 1:10 or about 1:10 and 1: 500 or about 1: 500, for example when diluted no more than 1:10 or about 1:10, 1:20 or about 1:20, 1:25 or about 1:25, 1:50 or about 1:50, 1: 100 or about 1: 100,1: 200 or about 1: 200, 1: 250 or about 1: 250, 1: 300 or about 1: 300, 1: 400 or about 1: 400, 1: 500 or about 1: 500, for example, 1:10, 1:20, 1:25, 1:30, 1:35, 1:40, 1:50, 1:55, 1:60, 1:65, 1:70 , 1:75, 1:80, 1:90, 1: 100, 1: 110, 1: 120, 1: 130, 1: 140, 1: 150, 1: 160, 1: 170, 1: 180, 1 : 190, 1: 200, 1: 210, 1: 220, 1: 230, 1: 235, 1: 240, 1: 250, 1: 260, 1: 270, 1: 280, 1: 290, 1: 300 , 1: 350,1: 400,1: 450, 1: 500 or more. Typically, the transparency of the liquid is maintained with increasing dilutions, for example, to infinity.
The transparency of the aqueous liquid dilution composition can be evaluated using one or more of a plurality of approaches, for example, qualitatively, by empirical evaluation, or quantitatively, by measuring the particle size and / or measuring the haze value of the liquid. In one example, a particular quantitative or qualitative transparency value is desired. In another example, the aqueous dilution liquid composition is desired to be as clear, less clear or more transparent than another liquid, for example, an aqueous dilution liquid composition prepared according to the methods provided or a beverage, for example, a beverage or other aqueous medium that does not contain the concentrate. For example, an aqueous liquid dilution composition, which contains the liquid concentrate diluted in a beverage, may be as clear or about as clear as the beverage itself, which does not contain any concentrate. The evaluation can be carried out qualitatively, for example by empirical observation or quantitatively, for example by calculating the particle size and / or the turbidity value (NTU) for the liquid or liquids.
(2) Empirical evaluation
The relative transparency / turbidity of the aqueous liquid dilution composition containing the dilute concentrate (eg, initial concentrate) can be qualitatively evaluated by observation. In one example, a liquid is considered transparent if it does not have an opaque appearance and / or if no particles are visible when the liquid is viewed with the naked eye. Transparency can be empirically evaluated by comparison with other liquids, eg, water, fruit juice, soda, and / or milk. For example, it may be desirable for the liquid to be as clear or about as clear as water or another liquid, eg, a beverage. For example, the liquid (containing the liquid concentrate diluted in an aqueous medium, eg a beverage) is as clear or about as clear as the aqueous medium that does not contain the liquid concentrate. In a related example, it may be desired that there is no substantial difference, for example, that there is no observable difference between the aqueous liquid dilution composition containing the concentrate and the aqueous medium without the concentrate. A clear liquid is not necessarily colorless, for example a yellow liquid that does not contain visible particles or opacity can be considered transparent.
(3) Particle size
Alternatively, the transparency of the aqueous dilution liquid composition containing the dilute concentrate (eg, initial concentrate) can be evaluated by measuring the particle size of the liquid. Methods for measuring particle size are known and any method for measuring particle size that can measure particle sizes in the appropriate ranges can be used as described below.
Particle size can be analyzed by commercial services, for example, from Delta Analytical Instruments, Inc, such as using a light scattering analyzer, for example a dynamic light scattering analyzer, for
ES 2 396 946 T3 example, the Horiba® LB-550, which can measure particle sizes within a range of 0.001 microns to 6 microns and uses a Fourier Transform / Iterative Deconvolution technique to report data and can measure sample concentrations from ppm to 40% solids; the Horiba® IA-920, which is a laser light scattering instrument that has a He-Ne laser and a tungsten lamp and can determine particle sizes from 0.02 microns to 2000 microns using Mie's Theory; or other analyzers available from Delta Analytical Instruments, Inc.
Alternatively, the particle size can be measured microscopically, for example by viewing the liquid under a microscope, for example at 640X magnification. With this method, the particle size can be quantified by comparing with a measuring device, for example , a ruler that is visible when the liquid is viewed under the microscope. If any particles are observable at this magnification, they are measured by comparison with the measuring device. At 640X magnification, for example, any particle that is about 25nm, 25nm, or greater than 25nm is visible, while particle sizes less than 25nm are typically not visible.
Typically, aqueous liquid dilution compositions are desired to have a particle size less than 200 nm or less than about 200 nm, eg, 5, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190 or 200 nm. Typically, aqueous dilution liquid compositions are desired to have a particle size less than 100 nm or about 100 nm, less than 50 nm or about 50 nm, or less than 25 nm or about 25 nm. Typically, the particle size of the aqueous liquid dilution composition containing the concentrate is between 5 nm or about 5 nm and 200 nm or about 200 nm, typically between 5 nm or about 5 nm and 50 nm or about 50 nm.
(4) Turbidity measurement
Alternatively, the transparency of the liquid can be analyzed by taking an optical turbidity measurement, which indicates the level of opacity or turbidity of a liquid, which is correlated with the size / number of suspended particles in the liquid. The more transparent a particular liquid is, the lower its turbidity value.
Turbidity can be measured optically, for example, using a nephelometer, an instrument with a light, and a detector. The nephelometer measures turbidity by detecting scattered light resulting from exposure of the liquid to incident light. The amount of scattered light is correlated with the amount of particulate matter in the liquid. For example, a ray of light will pass through the sample with low turbidity with little alteration. Other methods for measuring turbidity are well known and can be used in the provided methods and compositions.
The units of a turbidity value measured with a nephelometer are Nephelometric Turbidity Units (NTU). In one example, the aqueous dilution liquid composition containing the dilute concentrate is desired to have a low haze, eg, a haze value (NTU) of 30 or about 30; or an NTU value less than 30 or about 30, for example, less than 29 or about 29, less than 28 or about
28, under 27 or about 27, under 26 or about 26, under 25 or about 25<sub>; </sub>minor minor minor minor minor less than 9 or about 9<sub>;</sub> or about 6, less than 5 or about 5, less than 4 or about 4, less than 3 or about 3, less than 2 or about 2, less than 1 or about 1; or 29 or approximately
29, 28 or about 28, 27 or about 27, 26 or about 26, 25 or about 25, 24 or about 24, 23 or about 23, 22 or about 22, 21 or about 21 about about about about about 0. In Another example, the haze value of the aqueous liquid dilution composition is less than 200 or less than about 200, eg, 200, 175, 150, 100, 50, 25 or less.

In another example, it is desirable that the aqueous liquid dilution composition contain a haze value that is comparable to, for example, approximately equal to, the same as or less than or greater than the haze value of another liquid, for example, a Beverage that does not contain the liquid concentrate or an aqueous liquid dilution composition prepared by the methods provided.
ES 2 396 946 T3 iii. Selection of a formulation and modification of formulations
After evaluation of the initial concentrate (s), any particular formula is chosen or one or more modifications are made to the initial concentrate formula based on the results of the evaluation. When an initial concentrate does not show one or more desired properties, for example, a desired extent, based on the evaluation, the concentration of one or more ingredients can be adjusted and another initial concentrate can be prepared, repeating the process until a concentrate is prepared with the desired properties. For the modification of the initial concentrate, the amount of the polar solvent, surfactant and / or non-polar active ingredient can be adjusted, for example, to another concentration within the appropriate concentration range. Alternative ingredients can also be chosen. In one example, modifying the initial concentrate involves the addition of one or more additional ingredients. For example, if the evaluation reveals that the oil and water phases of the concentrate or the aqueous liquid dilution composition containing the dilute concentrate are separating, an emulsion stabilizer can be added to the formulation. In another example, a co-surfactant can be added to help emulsify the components of the concentrate. In another example, the phase (oil phase or aqueous phase) is modified, to which a particular ingredient is added. For example, the formulation can be modified to change whether the surfactant is added to the oil phase or the water phase.
In one example, when evaluation of the initial concentrate shows that it has the desired properties, no modifications are made. In this example, the starting concentrate formula is used to prepare the concentrate. When preparing two or more starting concentrates, for example with increasing concentrations of an ingredient, the formula of one or more starting concentrates can be chosen. Which formula is chosen can be based on which formula has the most desirable property. Alternatively, desirable properties can be balanced with relative amounts of ingredients. In one example, it is desirable to choose the formulation that uses the lowest or highest concentration of a particular ingredient but still provides a concentrate that produces a clear liquid upon dilution in an aqueous medium. In one example, the desired formulation is the formulation that has the lowest concentration of the surfactant, while still providing a concentrate that produces a clear liquid upon dilution in an aqueous medium. In another example, the desired formulation is the formulation that has the highest concentration of the non-polar active ingredient, while still providing a concentrate that provides a clear liquid upon dilution in an aqueous medium. In another example, the formulation that produces the most clear liquid is desired.
However, in another example, modifications are made to the formula even though the initial concentrate has the desired properties. For example, after determining that a particular concentrate formulation results in the desired properties, it may be desirable to modify the concentration of one or more ingredients to determine whether the same desired properties can be achieved if a higher or lower concentration of the ingredient (s) is used. . For example, it may be desirable to determine the lowest concentration of surfactant that can be used, while still generating a concentrate with a desired property, eg, the ability to form a clear liquid upon dilution in an aqueous medium. In another example, it may be desirable to determine the highest concentration of the nonpolar ingredient that can be incorporated into a concentrate, while still maintaining the desired property, eg, the ability of the concentrate to form a clear liquid upon dilution in an aqueous medium. In another example, one or more additional ingredients can be added after preparing an initial concentrate with the desired properties, for example, flavoring agents and / or pH adjusting agents.
The following sections describe the ingredients used in the provided liquid nanoemulsion concentrates.
b. Non-Polar Compounds
Concentrates contain one or more nonpolar compounds. Nonpolar compounds include any soluble lipophilic or lipid compounds, for example active ingredients, that have greater solubility in organic solvents (for example, ethanol, methanol, ethyl ether, acetone, and benzene) and in fats and oils, than in liquid compositions. aqueous dilution solutions, eg water. Typically, nonpolar compounds are poorly soluble in water, or for example insoluble in water or compounds that have low solubility in water. Nonpolar compounds include, but are not limited to, drugs, hormones, vitamins, nutrients, and other lipophilic compounds. Exemplary nonpolar compounds are shown below in this document. The provided methods and compositions can be used to dilute (eg, dissolve / disperse) any non-polar compound in an aqueous medium. In one example, the nonpolar compound differs from the surfactant, for example, it is not polyethylene glycol tocopheryl succinate (TPGS). In another example, the nonpolar compound is not vitamin E. Exemplary nonpolar compounds that can be used in the concentrates provided are:

i. Active ingredients containing Polyunsaturated Fatty Acid (PUFA)
Exemplary nonpolar compounds contained in concentrates are fatty acid-containing compounds, eg, active ingredients containing polyunsaturated fatty acids (PUFAs). Fatty acids
ES 2 396 946 T3 are straight chain hydrocarbon molecules with a carboxyl group (COOH) at one end of the chain. The
PUFAs are fatty acids that contain more than one carbon-carbon double bond in the fatty acid's carbon chain. PUFAs, particularly essential fatty acids, are useful as supplements to the diet.
Different nomenclatures can be used to describe fatty acid molecules. The lipid nomenclature, for example 18: 3ω-3, indicates the length of the carbon chain, the number of double bonds, and the position along the carbon chain of the first carbon-carbon double bond in a fatty acid . Using this nomenclature, each carbon along the chain is marked according to its position relative to one end of the chain. For example, the first carbon away from the carboxylate end is named a, the second is named β, and so on. The last carbon in the molecule (the one farthest from the carboxy group) is always marked ω (or omega on). The number of carbons and the number of double bonds are shown first in the lipid name of a fatty acid, separated by a colon. For example, the name 18: 3 indicates that the molecule has eighteen (18) carbons and three (3) double bonds. Following these numbers, the position in which the first double bond appears, with respect to the last carbon (ω) is indicated. For example, the nomenclature 18: 3ω-3 (or 18: 3 omega-3; or 18: 3 n-3) describes a fatty acid with eighteen (18) carbons and three (3) double bonds, the first of which appears on the third carbon from the omega carbon.
Alternatively, chemical nomenclature can be used. The chemical name of a fatty acid describes the position of each double bond. In the chemical name, the carbons are listed, starting with 1, starting with the carbon that is part of the carboxy group (COOH). In this way, with this numbering system, the carbon becomes marked 2. The fatty acid's chemical name indicates the first carbon (from the COOH end) to participate in each double bond.
Certain PUFAs are called essential fatty acids because mammals, including humans, cannot synthesize them using any known chemical route, and must obtain them from the diet or by supplementation. (US Patent No. 6,870,077; Covington, American Family Physician (2004), 70 (1): 133-140). The essential PUFAs are omega-3 fatty acids (ω3; n-3) and omega-6 fatty acids (ω-6; n-6). Omega-3 and omega-6 fatty acids are methylene interrupted polyenes that have two or more cis double bonds, separated by a single methylene group. Exemplary Omega-3 fatty acids are Alpha-Linolenic acid (α-Linolenic acid; ALA) (18: 3ω3) (a short chain fatty acid); Stearidonic acid (18: 4-3) (a short chain fatty acid); Eicosapentaenoic acid (EPA) (20: 5w3); Docosahexaenoic acid (DHA) (22: 6w3); Eicosatetraenoic acid (24: 4w3); Docosapentaenoic acid (DPA, Clupanodic acid) (22: 5w3); 16: 3ω3; 24: 5ω3 and / or nisinic acid (24: 6ω3). Longer chain Omega-3 fatty acids can be synthesized from aLa (the short chain omega-3 fatty acid). Exemplary Omega-6 fatty acids are Linoleic acid (18: 2-6) (a short chain fatty acid); Gamma-linolenic acid (GLA) (18: 3w6); Dihomo gamma linolenic acid (DGLA) (20: 3w6); Eicosadienoic acid (20: 2w6); Arachidonic acid (AA) (20: 4w6); Docosadienoic acid (22: 2w6); Adenic acid (22: 4w6); and Docosapentaenoic acid (22: 5-6).
Although the longer chain Omega-3 and Omega-6 essential fatty acids can be synthesized from ALA (the short chain omega-3 fatty acid) and Linolenic acid (LA), respectively, evidence suggests that the conversion of these short-chain fatty acids in humans is slow. Thus, a major source of essential long-chain PUFAs is in the diet (for example, see Ross et al., Lipids in Health and Disease (2007), 6:21; Lands, The FASEB Journal (1992), 6 (8): 2530). Dietary supplements containing PUFAs, particularly essential PUFAs, are desirable for protection against cardiovascular disease, inflammation, and mental weakness (see for example, Ross et al., Lipids in Health and Disease (2007), 6:21; Lands, The FASEB Journal (1992), 6 (8): 2530; US Patent No. 6,870,077). Evidence suggests that essential fatty acids, particularly EPA and DHA, in the form of foods and nutritional supplements, play a role in the prevention of numerous pathologies, including cardiovascular disease, inflammation, mental health and behavioral diseases and disorders (see, for For example, Ross et al., Lipids in Health and Disease (2007), 6:21; Lands, The FASEB Journal (1992), 6 (8): 2530; US Patent No. 6,870,077; Covington, American Family Physician (2004), 70 (1): 133-140).
Omega-9 fatty acids are not essential PUFAs. Exemplary omega-9 fatty acids are Oleic acid (which is monounsaturated) (18: 1 w9); Eicosenoic acid (20: 1 w9); Meadic acid (20: 3 w9); Erucic acid (22: 1 w9); and Nervonic acid (24: 1 * 9).
Conjugated fatty acids are PUFAs with two or more conjugated double bonds. Conjugated fatty acids can be used as nutritional supplements. Exemplary conjugated fatty acids are conjugated linoleic acid (CLA), eg, 18: 2ω7, 18: 2ω6; Conjugated Linolenic Acid, eg, 18: 3-6,18: 3-5; and other conjugated fatty acids, for example, 18: 3ω3, 18: 4ω3, and 20: 5ω6.
(1) Omega-3 fatty acid compounds
Exemplary PUFA-containing active ingredients that can be used in the compositions provided are compounds containing one or more omega-3 (ω3; n-3) fatty acids, for example, compounds containing
ES 2 396 946 T3 DHA and / or EPA fatty acids, for example marine oils for example fish oil, krill oil and seaweed oil; and ALA fatty acid-containing compounds, for example flaxseed oil.
Typically, oily and aqueous compositions containing long chain polyunsaturated fatty acids (PUFAs) are susceptible to oxidation, rendering them unstable and giving them an unpleasant taste. The ingredients and relative concentrations thereof, as well as the methods for preparing the concentrates, contribute to the desirable properties of concentrates containing DHA / EPA. In one example, the ingredients and methods minimize the fishy odor and / or taste of DHA / EPA compositions and increase their stability over time. In one aspect, the compounds in the concentrates have low oxidation, contributing to these desirable properties.
(a) DHA / EPA
Exemplary non-polar active ingredients containing one or more omega-3 fatty acids, which can be used in the compositions provided, are compounds containing DHA and / or EPA, eg, marine oil, eg, fish oil, oil krill and seaweed oil. Any oil containing DHA and / or EPA can be used. In one example, the non-polar active ingredient contains between 20% or about 20% and 40% or about 40% DHA. In another example, the nonpolar active ingredient contains between 25% or about 25% and 35% or about 35% DHA. In another example, the non-polar active ingredient contains at least 70% or about 70% by weight (w / w), DHA, for example, at least 75% or about 75%, at least 80%. or about 80%, at least 85% or about 85%, or at least 90% or about 90% by weight (w / w), of DHA. In another example, the non-polar active ingredient contains between 5% or about 5% and 15% or about 15% EPA, for example 5, 6, 7, 8, 9, 10, 11, 12 , 13, 14 or 15% by weight (w / w), of EPA. In another example, the nonpolar active ingredient comprises no more than 10% or about 10% EPA or less than 10% or about 10% EPA. In another example, the nonpolar active ingredient contains DHA and EPA, for example, DHA representing at least 20% or about 20% by weight of the nonpolar active ingredient and EPA representing no more than 13% or about 13% of the nonpolar active ingredient, eg, no more than 10% or about 10% by weight of the nonpolar active ingredient. In another example, the nonpolar active ingredient contains DHA, representing at least 35% or about 35% of the nonpolar active ingredient and EPA representing no more than 13% or about 13% of the nonpolar active ingredient, for example, no more than 10% or about 10% of the non-polar active ingredient. In another example, the non-polar active ingredient contains dHa and EPA, for example, DHA representing at least 70% or about 70% of the non-polar active ingredient and EPA representing no more than 13% or about 13% of the active ingredient. non-polar, eg, no more than 10% or about 10% of the non-polar active ingredient.
(i) Fish oils
Exemplary PUFA-containing non-polar active ingredients that can be used in the provided compositions are fish derived oils containing DHA, EPA, or both DHA and EPA. In particular, cold-water marine fish is a known source of Omega-3 fatty acids (US Patent No. 4,670,285). Suitable fish oil containing DHA, EPA, or both DHA and EPA can be obtained from any of a number of commercial sources, for example, fish oils available from Jedwards International, Inc., any of which can be used with the compositions provided.
Fish oils are typically extracted from fish tissue, for example frozen fish tissue. In one example, the fish oil is an unflavored fish oil, for example cod liver oil, which has been isolated from fish, for example cod liver, and then refined and deodorized or has been treated in some other way so as to make its taste neutral, for example, as described in International Publication Nos. WO 00/23545 and WO 2004/098311. In one example, these fish oils are isolated from frozen fish tissue by a process that minimizes oxidation. Exemplary of such unflavored fish oils are Denomega ™ 100, Borregaard Ingredients, Sarpsborg, Norway; distributed by Denomega Nutritional Oils AS, Boulder, CO. Typically, unflavored fish oil, for example cod liver oil, contains between 25% or about 25% and 35% or about 35% Omega-3 fatty acids, for example 34% of Omega-3 fatty acids. In one example, fish oil, for example, Denomega ™ 100 oil contains 13% or about 13% DHA and 13% or about 13% EPA.
Fish oils containing high amounts of Omega-3 fatty acids, eg high amounts of DHA, are also exemplary of fish oils that can be included in the provided compositions. In one example of such fish oil they contain at least about 85% DHA, typically more than 85% DHA, and at least about 90% Omega-3 fatty acids, typically greater than 90% Omega-3 fatty acids. . In another example, fish oil may contain 98% PUFA, 89% Omega-3 fatty acids, approximately 70% DHA, approximately 10% EPA, 8.9% Omega-6 fatty acids, and 0.7 % Omega-9 fatty acids.
ES 2 396 946 T3
Exemplary of a fish oil containing high amounts of Omega-3 fatty acids that can be used as the non-polar compound in the provided compositions is Omega-3 Fish Oil EE (O3C Nutraceuticals, supplied by Jedwards International Inc., Quincy , MA), which contains 89% Omega-3 fatty acids, 8.9% Omega-6 fatty acids, 0.7% Omega-9 fatty acids, 0.1% saturated fatty acids, 1.0% of monounsaturated fatty acids, 74.5% Docosahexaenoic fatty acids (DHA), 9.3% Eicosapentaenoic fatty acids (EPA) and 98% polyunsaturated fatty acids (PUFA).

Exemplary of the non-polar active ingredients are compounds containing Coenzyme Q, for example, Coenzyme Q10 (also referred to as CoQ10, ubiquinone, ubidecarenone, ubiquinol and vitamin Q10). Coenzyme Q compounds are benzoquinone compounds that contain isoprenyl units. The number of isoprenyl units in each of the different CoQ species is indicated by a number following the CoQ. For example CoQ10 contains 10 isoprenyl units. Coenzyme Q10 is a predominant Coenzyme Q species.
Coenzyme Q can exist in two different forms: an oxidized form and a reduced form. When the oxidized form of a Coenzyme Q species is reduced by one equivalent, it becomes ubisemiquinone, denoted QH, which contains a free radical in one of the oxygens on the benzene ring of benzoquinone.

(1) Coenzyme Q10
Exemplary of the non-polar active ingredients containing Coenzyme Q that can be used in the compositions provided active ingredients containing Coenzyme Q10. Coenzyme Q10 (also known as CoQ10, ubiquinone, ubidecarenone, ubiquinol, and vitamin Q10) is a benzoquinone compound that contains 10 isoprenoid units. The Q in the name refers to Quinone and the 10 refers to the number of isoprenoid units.

Both oxidized and reduced CoQ10 are exemplary of the coenzyme Q species that can be used as active ingredients in the compositions provided.
CoQ10 has electron transfer capabilities and is present in cell membranes such as those of the endoplasmic reticulum, peroxisomes, lysosomes, vesicles, and in mitochondria. A decrease in the synthesis of natural CoQ10 has been observed in sick and elderly people. Due to this observation and its powerful antioxidant properties, CoQ10 is used as a dietary supplement and a treatment for diseases such as cancer and heart disease. CoQ10, however, has a relatively poor bioavailability.

c. Surfactants
The compositions provided contain surfactants. For example, in addition to the nonpolar compound (s), liquid concentrates contain one or more surfactants. In the provided methods for producing the concentrates, the surfactant is added to the water phase, the oil phase, or the water and oil phase. The compositions may additionally contain one or more co-surfactants or emulsifiers.
Surfactants are added to aqueous liquids, such as in provided compositions (eg, concentrates and aqueous liquid dilution compositions) to form micelles, which contain the nonpolar compound (s). The hydrophilic portion or portions of the surfactant molecules are oriented toward the outside of the micelle, in contact with the aqueous medium, while the hydrophobic portion or portions of the surfactant molecules are oriented toward the center of the micelle, in contact with the compound. or nonpolar compounds, which are contained in the center of the micelle. Micelles can contain more than one surfactant and / or co-surfactant. The properties of the compositions provided, eg, the particle size of the compositions and the desirable properties related to the particle size, are influenced by the choice of the surfactant (s) and the relative amount (concentration) of the surfactant. For example, the HLB of the surfactant (s) can affect the particle size, transparency, taste, odor, crystal formation, and other properties of the compositions provided. Similarly, the concentration of the surfactant compared to the concentration or concentrations or concentrations of other ingredients, particularly compared to the concentration of the polar solvent (s) and the concentration of the non-polar compound (s), can affect various desirable properties, for example, the ability to disperse or dissolve in aqueous media, for example, to form an aqueous liquid composition for dilution or with a pleasant taste and / or odor.
Surfactants (and co-surfactants) are molecules that contain hydrophobic and hydrophilic moieties. In one example, the hydrophobic portion is a hydrophobic tail and the hydrophilic portion is a hydrophilic head of the surfactant molecule.
Exemplary of the surfactants that can be used in the provided compositions and methods are surfactants having an HLB value of between 14 or about 14 and 20 or about 20, typically between 16 or about 16 and 18 or about 18. Exemplary suitable surfactants include, but are not limited to, surfactants derived from Vitamin E, such as surfactants derived from tocopherol and / or tocotrienol in which the Vitamin E moiety represents the hydrophobic region of the surfactant, and is attached, via linker to another moiety, such as a polyethylene glycol (PEG) moiety, which provides the hydrophilic portion of the surfactant. Vitamin-E derived surfactants include, but are not limited to, tocopherol derived surfactants, including polyalkylene glycol derivatives of tocopherol, typically polyethylene glycol (PEG) derivatives of tocopherol, such as polyethylene glycol tocopherol succinate (TPGS), TPGS analogs, TPGS homologs and TPGS derivatives. Alternatively, the surfactants can be other PEG derivatives that have similar properties, for example, PEG derivatives of sterols, for example a cholesterol or sitosterol (including, for example, any of the PEG derivatives disclosed in US Pat. Nos. 6,632,443) or PEG derivatives of other fat-soluble vitamins, eg, some forms of Vitamin A (eg, Retinol) or Vitamin D (eg, Vitamin D1-D5).
The HLB value of a surfactant comes from a semi-empirical formula; HLB values are used to index surfactants according to their relative hydrophobicity and hydrophilicity. An HLB value is a numerical representation of the relative representation of hydrophilic groups and hydrophobic groups in a surfactant or a mixture of surfactants. The weight percent of these respective groups indicate properties of the molecular structure. See, for example, Griffin, WCJ Soc. Cos. Chem. 1: 311 (1949).
ES 2 396 946 T3
Surfactant HLB values range from 1-45, while the range for nonionic surfactants is typically 1-20. The more lipophilic a surfactant is, the lower its HLB value. Conversely, the more hydrophilic a surfactant is, the higher its HLB value. Lipophilic surfactants have higher solubility in oil and lipophilic substances, while hydrophilic surfactants dissolve more easily in aqueous liquids. In general, surfactants with HLB values greater than 10 or greater than about 10 are called hydrophilic surfactants, while surfactants having HLB values less than 10 or less than about 10 are called hydrophobic surfactants. HLB values are known for a number of surfactants. Table 1A shows HLB values of exemplary surfactants and cosurfactants.
The surfactants in the compositions provided are typically nonionic surfactants and typically have an HLB value between and about 14 and about 20. Particular examples of suitable surfactants include PEG-derived surfactants, such as PEG derivatives of Vitamin E having appropriate HLB values, such as an HLB value between 14 or about 14 and 20 or about 20, eg, 14, 15, 16, 17, 18, 19, 20, about 14, about 15, about 16, about 17, about 18, about 19, or about 20. Typically, the surfactants are natural surfactants, for example, a surfactant that is GRAS (generally recognized as safe) by the FDA and / or certified Kosher.
i. Surfactants derived from vitamin E
Surfactants include, but are not limited to, Vitamin-E derived surfactants such as tocopherol and / or tocotrienol derived surfactants, in which the Vitamin E moiety represents the hydrophobic region of the surfactant, and is linked, through a linker, to other moieties, such as a polyethylene glycol (PEG) moiety, which provides the hydrophilic portion of the surfactant. Vitamin E-derived surfactants include, but are not limited to, tocopherol-derived surfactants, including polyethylene glycol derivatives of tocopherol, typically polyethylene glycol (PEG) derivatives of tocopherol, such as tocopherol polyethylene glycol succinate (TPGS), TPGS analogs, homologues of TPGS and derivatives of TPGS. Alternatively, the surfactants may be other PEG derivatives having similar properties as TPGS and TPGS analogs, for example, PEG derivatives of sterols, for example, a cholesterol or a sitosterol (including, for example, any of the derivatives of PEGs disclosed in U.S. Patent No. 6,632,443) or PEG derivatives of other fat-soluble vitamins, for example, some forms of Vitamin A (for example, Retinol) or Vitamin D (for example, Vitamin D1-D5).
(1) PEG derivatives of Vitamin E
Vitamin E derived surfactants (eg, tocopherol derived surfactants or tocotrienol derivatives) include polyalkylene glycol derivatives of Vitamin E, typically polyethylene glycol (PEG) derivatives of Vitamin E, eg, PEG derivatives of tocopherol and tocotrienol. Suitable PEG derivatives of Vitamin E typically contain one or more tocopherols or tocotrienols, linked (eg, via an ester, ether, amide, or thioester bond) to one or more PEG moieties, through a linker, eg, a dicarboxylic acid linker. An exemplary surfactant is schematically shown below:
<td>PEG -</td><td>- Crimping -</td><td>- Vitamin E</td>
where the line between the PEG and the Crimp; and the line between the Linker and Vitamin E each independently represent a covalent bond selected from an ester, ether, amide, or thioester.
Typically, PEG derivatives of Vitamin E are prepared by linking the PEG moiety, by esterification, to a vitamin E-linker conjugate (eg, a tocopherol-linker conjugate). In one example, the tocopherol-linker conjugate is formed first by covalently linking (by esterification) the hydroxyl moiety of tocopherol with a dicarboxylic acid to produce an ester bond. In this example, the tocopherol-linker conjugate is a tocopherol ester (such as tocopherol succinate). The esterification reaction can be carried out by any number of known methods (see, for example, US Patent Nos. 2,680,749, 4,665,204, 3,538,119, and 6,632,443). To prepare the tocopherol-PEG surfactant, the resulting tocopherol ester is then attached (via linker) to the PEG molecule, in another esterification reaction. In this example, the resulting surfactant is a polyethylene glycol tocopherol diester (TPGD).
Alternatively, PEG derivatives of a tocopherol-linker or tocotrienol-linker conjugate can be prepared by other methods. Various methods known in the art can be used to produce PEG derivatives to link a PEG molecule to tocopherol-linker or tocotrienol-linker compounds. For example, a tocopherol-linker conjugate can be covalently attached to the molecule through an amide, ether, or thioether bond. For example, a tocopherol-linker conjugate containing an amine group can be reacted with a PEG-NHS derivative to form an amide bond between the tocopherol-linker and the PEG molecule. A tocopherol-linker conjugate containing an amine group can be reacted with a PEG49 derivative.

In another example, a tocopherol-linker containing a carboxylic acid can be activated to the corresponding acid halide and reacted with a derivative of PEG-SH to form a thioester bond between the tocopherol-linker and the molecule of
PEG.

Exemplary tocopherols are da tocopherols and d, 1-tocopherols. To prepare the surfactant, tocopherol is typically esterified with a linker, eg, a dicarboxylic acid, to form a tocopherol ester, which is then attached to a PEG moiety.

Exemplary of suitable PEG residues are PEG residues having varying chain lengths, and varying molecular weights, for example, PEG 1000, PEG 200, PEG 500 and PEG 20,000. The numbers following the individual PEG residues indicate the molecular weight (in kilodaltons (kDa) of the PEG residues. The PEG moiety of the tocopherol-derived surfactant typically has a molecular weight between 200 kDa or about 200 kDa and 20,000 kDa or about 20,000 kDa, typically between 200 kDa or about 200 kDa and 6000 kDa or about 6000 kDa, for example, between 600 kDa. or about 600 kDa and 6000 kDa or about 6000 kDa, typically between 200 kDa or about 200 kDa and 2000 or about 2000 kDa, between 600 or about 600 kDa and 1500 kDa or about 1500 kDa, such as, but not limited to, 200, 300, 400, 500, 600, 800, and 1000 kDa.

Also exemplary of suitable PEG residues are PEG residues that are modified, for example, methylated PEG (m-PEG), which is a PEG chain protected with a methyl group. Other known PEG analogs can also be used. PEG moieties can be selected from any reactive PEG including, but not limited to, PEG-OH, PEG-NHS, PEG-aldehyde, PEG-SH, PEG-NH2, PEGCO2H, and branched PEG.
(c) Crimps
Typically, the PEG derivatives of Vitamin E are diesters or other esters, eg, triesters. When the PEG derivative is a diester, the linker that binds Vitamin E to PEG is typically a carboxylic acid, typically a dicarboxylic acid as for example in polyethylene glycol tocopherol succinate (TPGS), where the linker is a succinic acid, The surfactant is prepared by an esterification region linking a PEG moiety and a tocopherol ester of the dicarboxylic acid. In another example, the linker is another molecule, for example, an amino acid, such as glycine, alanine, 5-aminopentanoic acid, or 8-aminooctanoic acid; or an amino alcohol, such as ethanolamine.
(d) Polyethylene glycol diesters of Tocopherol and polyethylene glycol of Tocotrienol (Dicarboxylic acid esters of Vitamin E bound to PEG)

Exemplary of the Vitamin E diesters are polyethylene glycol tocopherol diesters (TPGD) and polyethylene glycol tocotrienol diesters.
When the tocopherol or tocotrienol ester attached to the PEG moiety is a tocopherol ester of a dicarboxylic acid (for example, tocopherol succinate), the linker is a dicarboxylic acid (a carboxylic acid having two carboxy groups, for example, acid succinic). In this example, the PEG diester of tocopherol or tocotrienol is formed by an esterification reaction, in which PEG is bound to a tocopherol ester of a dicarboxylic acid.

Examples of PEG diesters of tocopherol and tocotrienol that can be used as surfactants in the compositions and methods provided include, but are not limited to: tocopherol polyethylene glycol succinates (TPGS; including Da TPGS and d, 1-TPGS; see for example, Patent US Patent No. 3,102,078), polyethylene glycol tocopherol sebacate (PTS; see, for example, US Patent No. 6,632,443), polyethylene glycol tocopherol dodecanedioate (PTD; see, for example, U.S. Patent No.
6,632,443), polyethylene glycol tocopherol suberate (PTSr; see for example US Patent No.
6,632,443), polyethylene glycol tocopherol azelaate (PTAz; see for example, U.S. Patent No.
6,632,443), tocotrienyl polyoxyethanyl sebacate (PTrienS, eg, PTrienS-600; see US Patent No. 6,632,443), as well as analogs, homologues and derivatives or any of the diesters of tocopherol.
(e) Other PEG Esters of Vitamin E
In another example, the tocopherol ester attached to the PEG to form the PEG diester of tocopherol is a tocopherol ester of a tricarboxylic acid, for example, Citric acid, Isocitric acid, Aconitic acid and Propane1,2,3-tricarboxylic acid ( tricarbalilic acid, carboxylic acid) or a carboxylic acid having three or more carboxy groups.
In another example, the PEG derivatives of tocopherol are polyethylene glycol tocopherol triesters (TPGT), for example, esters containing a tocopherol, a linker, a PEG moiety, and an additional moiety, for example an additional tocopherol, a second PEG moiety or a water soluble group, such as a quaternary amine. In one example, when the triester contains two PEG moieties, each PEG moiety has a shorter chain length (and lower molecular weight) than the PEG moiety in a PEG derivative of tocopherol, which has similar properties, containing only one PEG chain.
(f) TPGS surfactants
Exemplary are the tocopherol polyethylene glycol diester surfactants TPGS and analogs, homologues and derivatives thereof. TPGS is a natural surfactant that is GRAS and Kosher certified and thus desirable for use in products designed for human consumption, eg, beverages, food, and nutritional supplements. The TPGS typically has an HLB value between 16 or about 16 and 18 or about 18. Exemplary of the TPGS surfactants is TPGS-1000, which has a PEG residue of 1000 kDa. Exemplary of the TPGS surfactants that can be used in the provided compositions is the food grade TPGS surfactant marketed under the name Eastman Vitamin E Food grade TpGs® from Eastman Chemical Company, Kingsport, TN. This surfactant is a water-soluble form of vitamin E from a natural source, which is prepared by esterifying the carboxyl group of crystalline d-alpha-tocopheryl acid succinate with polyethylene glycol 1000 (PEG 1000) and contains between 260 and 300 mg / g of tocopherol. total. A similar compound can be prepared by esterifying the carboxyl group of synthetic Vitamin E form d, 1 with PEG 1000. This forms a clear liquid when dissolved 20% in water. This tocopheryl polyethylene glycol is a water-soluble preparation of a fat-soluble vitamin (vitamin E), for example, as disclosed in US Patent Nos. 3,102,078, 2,680,749 and US Published Applications N ° 2007/0184117 and 2007/0141203. The PEG moiety of alternative TPGS surfactants can have a molecular weight range between about 200 kDa or 200 kDa to 20,000 kDa or about 20,000 kDa, for example, between 600 kDa or about 600 kDa and 6000 kDa or about 6000 kDa, typically between 600 kDa or about 600 kDa and 1500 kDa or about 1500 kDa. Also exemplary of the TPGS surfactant that can be used in the provided compositions is Natural Water Soluble Vitamin E (TPGS) available from ZMC-USA, The Woodlands, Texas. Any known source of TPGS, or any analog, homologous or derivative thereof can be used.
Exemplary TPGS analogs are compounds other than TPGS, which are similar to a parent TPGS compound but differ slightly in composition, e.g., with the variation, addition, or removal of an atom, one or more units (e.g., a methylene unit (s) - (CH2) n) or one or more functional groups.
At room temperature, TPGS is typically a low melting waxy solid. In one example, the TPGS is heated before use, for example, to at least the melting temperature, for example, between 37 ° C or about 37 ° C and 41 ° C or about 41 ° C and the amount is poured desired. In another example, the TPGS can be added as a waxy solid to a container and heated with the heating apparatus.
They are also exemplary of the TPGS analog surfactants, including surfactants derived from Vitamin E, including PEG derivatives of Vitamin E, including PEG diesters of vitamin E, such as but not limited to, polyethylene glycol tocopherol (PTS) sebacate, dodecanediate polyethylene glycol tocopherol (PTD), polyethylene glycol tocopherol suberate (PTSr), Tocopherol polyethylene glycol azelaate (PTAz) and polyoxethanyl tocotrienyl sebacate (PTrienS) as well as other PEG derivatives of Vitamin E.
ii. Surfactant concentration
Typically, the concentration of the surfactant (s) in a particular concentrate composition is selected as described herein, by formulating an initial concentrate with a concentration of
ES 2 396 946 T3 surfactant (s) within a starting concentration range, followed by evaluation of the initial concentrate and, optionally, adjusting the concentration of the surfactant (s). Alternatively, the concentration of the surfactant can be chosen based on the concentration of the surfactant in one or more existing liquid concentrate formulas. Typically, the surfactant concentration is between 16% or about 16% and 30% or about 30% (w / w), for example, 16% or about 16%, 17% or about 17 %, 18% or about 18%, 19% or about 19%, the
20% or about 20%, 21% or about 21%, 22% or about 22%, 23% or about 23%, 24% or about 24%, 25% or about 25%, 26% or about 26%, 27% or about 27%, 28% or about 28%, 29% or about 29%, 30% or about 30% by weight ( w / w) of the concentrate. Exemplary of surfactant concentrations within the appropriate concentration range are 17.75% and 25.2% (w / w) of the concentrate. Typically, the surfactant concentration is less than or equal to 30% or about 30% (w / w) of the concentrate.
In one example, the surfactant concentration range is between 17% or about 17% and 25% or about 25% (w / w) of the concentrate. In another example, the concentration range of the surfactant is between 18% or about 18% and 25% or about 25% (w / w) of the concentrate. In another example, the concentration range of the surfactant is between 18% or about 18% and 20% or about 20% (w / w) of the concentrate. In another example, the concentration range of the surfactant is between 17% or about 17% and 20% or about 20% (w / w) of the concentrate. In another example, the concentration range of the surfactant is between 16% or about 16% and 20% or about 20% (w / w) of the concentrate.
iii. HLB
Exemplary of the properties of the surfactant (s) that contribute to the desirable properties of the compositions is the HLB (hydrophilic-lipophilic balance) of the surfactant (s). Generally, HLB is a value, derived from a semi-empirical formula, that is used to index surfactants according to their relative hydrophobicity / hydrophilicity. An HLB value is a numerical representation of the relative representation of hydrophilic groups and hydrophobic groups in a surfactant or mixture of surfactants. The weight percent of these respective groups indicates properties of the molecular structure. See, for example, Griffin, WCJ Soc. Cos. Chem. 1: 311 (1949).
Surfactant HLB values range from 1-45, while the range for nonionic surfactants is typically 1-20. The more lipophilic a surfactant is, the lower its HLB value. Conversely, the more hydrophilic a surfactant is, the higher its HLB value. Lipophilic surfactants have higher solubility in oil and lipophilic substances while hydrophilic surfactants dissolve more easily in aqueous media. In general, surfactants with HLB values greater than 10 or greater than about 10 are called hydrophilic surfactants, while surfactants having HLB values less than 10 or less than about 10 are called hydrophobic surfactants.
HLB values have been determined and are available for a plurality of surfactants (eg, see US Patent No. 6,267,985). It should be appreciated that the HLB values for a given surfactant or co-surfactant can vary, depending on the empirical method used to determine the value. Thus, the HLB values of surfactants and co-surfactants provide a rough guide for formulating compositions based on relative hydrophobicity / hydrophilicity. For example, a surfactant is typically selected from surfactants having HLB values within a particular range of surfactant or co-surfactant that can be used for guide formulations. Table 1A shows the HLB values of exemplary surfactants and cosurfactants.
The surfactants and HLB values set forth in Table 1A are exemplary. Any known surfactant or co-surfactant can be used with the provided compositions (see, for example, US Patent No. 6,267,985), provided it has an appropriate HLB value, such as an HLB value between and about 14 and about 20. The surfactant (s) used in the concentrate provided typically has an HLB value between 14 or about 14 and 20 or about 20, eg, 14, 15, 16, 17, 18, 19, 20, about 14, about 15, about 16, about 17, about 18, about 19, or about 20. Exemplary surfactants include, but are not limited to, nonionic surfactants such as surfactants derived from polyethylene glycol (PEG), including, but not limited to, PEG derivatives of Vitamin E, such as PEG diesters of tocotrienol or tocopherol, such as TPGS (for eg, TPGS 1000) and TPGS analogs, homologues, and derivatives. Other known surfactants having HLB values between 14 or about 14 and 20 or about 20, typically between about 15 and 18, may also be suitable. For example, surfactants having similar properties to TPGS can also be used. Typically the surfactant is a natural surfactant, for example a surfactant that is GRAS (generally recognized as safe) by the FDA and / or certified Kosher.
ES 2 396 946 T3
d. Co-surfactants (emulsifiers)
In one example, the liquid concentrate additionally contains one or more co-surfactants (emulsifiers). For example, a co-surfactant can be included to improve the emulsion of the active ingredient and / or the stability of the composition, for example by preventing or slowing the oxidation of the nonpolar compound. Exemplary of a cosurfactant used in the concentrates provided is a phospholipid, eg, phosphatidylcholine.
i. Phospholipids
Exemplary of the co-surfactants that can be used in the provided compositions are phospholipids. Phospholipids are amphipathic lipid-like molecules, typically containing a hydrophobic portion at one end of the molecule and a hydrophilic portion at the other end of the molecule. A number of phospholipids can be used as ingredients in the provided compositions for example, lecithin, including phosphatidylcholine (PC), phosphatidylethanolamine (PE), distearoylphosphatidylcholine (DSPC), phosphatidylserine (PS), phosphatidylglycerol (PG), phosphatidic acid (PA) (PI), sphingomyelin (PMS), or a combination thereof. Typically, the phospholipid is phosphatidylcholine (PC), which is sometimes referred to by the general name lecithin. Exemplary of the phospholipids that can be used as co-surfactants in the compositions provided are the phospholipids marketed by Lipoid, LLC, Newark, NJ, for example, Purified Egg Lecithins, Purified Soybean Lecithins, Egg Lecithins, and Soybean Seed. Hydrogenated, Egg Phospholipids, Soya Seed Phospholipids, Hydrogenated Egg Phospholipids and Soya Seed. Synthetic Phospholipids, PEGylated Phospholipids, and phospholipid combinations sold by Lipoid, LLC. Exemplary of phosphatidylcholine that can be used as a co-surfactant in the compositions provided is the phosphatidylcholine composition sold by Lipoid, LLC, under the name Lipoid S 100, which is derived from a soybean extract and contains more than 95% or more of about 95% phosphatidylcholine.
In one example, the phospholipid, eg, PC, represents less than or equal to 1% or about 1% by weight (w / w) of concentrate. In one example, phosphatidylcholine represents between 0.1% or about 0.1% and 1% or about 1%, for example 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.6, 0.65, 0.66, 0.6690, 0.7, 0.75, 0.8, 0, 85, 0.9, 0.95 or 1% by weight (w / w) of the concentrate. In one example, the phospholipid represents between 0.15% or about 0.15% and 0.7% or about 0.7% by weight (w / w) of the concentrate.
and. Polar solvents
The compositions, including liquid nanoemulsion concentrates and liquid dilution compositions, additionally include polar solvents. Polar solvents are well known in the art. The polarity of a solvent generally indicates which compounds are soluble in the solvent and in which other solvents / liquids the solvent is miscible. Generally speaking, polar compounds are more easily solubilized in water and other polar solvents that are nonpolar compounds. Polar solvents are more likely to be miscible with water and other polar and liquid solvents.
The polarity of a solvent can be evaluated by measuring a number of different parameters according to well known methods (see for example, Prizbytek, High Purity Solvent Guide, Burdickand Jackson Laboratories, Inc., 1980), such as by determining a solvent property such as the dielectric constant, the dipole moment or the polarity index. For example, polar solvents generally have high dielectric constants, typically dielectric constants greater than or about 15 (see for example, Lowery et al., Mechanism and Theory in Organic Chemistry, Harper Collins Publishers, 3<sup>to</sup> ed., 1987, p. 177), such as about 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, or greater than 90. For example, the dielectric constant of water is at or about 80.10. Polar solvents generally have high polarity indices, typically greater than or about 3 (see, for example, Snyder, Classification of the solvent properties of common liquids, J. Chromatography A, 92: 223-230, 1974), such as of or about 3, 4, 5, 6, 7, 8 or 9 or greater than 9. Polar solvents generally have large dipole moments, typically greater than or about 1 , 4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6 , 3.0, 3.5, 4 or greater than 4 Debye (see, for example, CRC Handbook of Chemistry and Physics, Lide, ed., 82nd edition, CRC Press, 2001, p. 15 (14) 15 (18 )). Other methods for evaluating solvent polarity are known in the art including but not limited to the Kosower Z scale (Kosower, An introduction to physical organic chemistry, Wiley, 1969, p. 293), the donor number and donor acceptor scale ( Gutmann, Solvent effects on the reactivities of organometallic compounds, Coord. Chem. Rev., 18: 225-255, 1976) and the Hildebrand solubility parameters (see, for example, Giddings et al., High pressure gas chromatography of nonvolatile species. Compressed gas is used to cause migration of intractable solutes, Science, 162: 67-73, 1968).
Polar solvents include polar protic solvents and polar aprotic solvents. A polar protic solvent (eg, water, methanol, ethanol) contains a hydrogen atom attached to an electronegative atom, so that hydrogen has a proton-like character and / or the bond between hydrogen and an electronegative atom is polarized . Polar aprotic solvents on the other hand (eg acetone, acetonitrile), generally do not contain positively polarized hydrogen atoms.
ES 2 396 946 T3
Polar solvents in the compositions provided are typically polar protic solvents, including, but not limited to, water; alcohols, including but not limited to dihydric alcohols (eg glycols, eg propylene glycol, ethylene glycol, tetraethylene glycol, triethylene glycol, trimethylene glycol), containing two hydroxyl groups, trihydric alcohols (eg glycerin, butane-1,2,3 -triol, pentane-1,3,5-triol, 2-amino-2-hydroxymethyl-propane-1,3-diol), containing three hydroxyl groups, monohydric alcohols (for example, methanol, ethanol, propanol, isopropanol, n-butanol and t-butanol) and other alcohols; and acids, including but not limited to acetic acid and formic acid. Other polar solvents include, but are not limited to, acetone, acetonitrile, butyl acetate, dimethylformamide, dimethylsulfoxide, dioxane, ethyl acetate, tetrahydrofuran, and hexamethylphosphoric triamide. Typically, the polar solvent is water or is an alcohol that typically contains two or more hydroxyl groups, such as a trihydric or dihydric alcohol, such as, but not limited to, glycerol and propylene glycol. Polar solvents further include low molecular weight polyethylene glycols (PEGs), such as PEGs having a molecular weight of no greater than or about 600 kDa, such as between or about 200 kDa and or about 600 kDa, typically no greater than or about 400 kDa, eg, no more than 200 kDa.
In one example, the polar solvent has a dielectric constant greater than or about 15 and typically between or about 20 and or about 80, such as or about 80.1, 46.53, or 28.67. In another example, the polar solvent has a polarity index between or about 3 and about 9. In another example, the dipole moment of the polar solvent is between 1.5 and 3, and typically between or about 1.8 and 2.8, such as 1.9, 2.6 and 2.2 (for dielectric constants of solvents see, for example, Landolt-Bornstein, New Series IV / 17, Static Dielectric Constants of Pure Liquids and Binary Liquid Mixtures, Springer, 2008; and CRC Handbook of Chemistry and Physics, Lide, ed., 82<sup>to</sup> edition, CRC Press, 2001; for the dipole moment of solvents, see, for example, CRC Handbook of Chemistry and Physics, Lide, ed., 82nd edition, CRC Press, 2001) and for polarity indices of solvents, see, for example, Snyder, Classification of the solvent properties of common liquids, J. Chromatography A, 92: 223-230, 1974).
The amount of the polar solvent is typically a high concentration, for example, within a concentration range of between 60% or about 60% and 80% or about 80% by weight (w / w) of the

liquid concentrates provided 71.74%, 75.8165%, 74.25%, 68.7865% and 68.29% (w / w) of the concentrate. In one example, the concentration range of the polar solvent is between 65% or about 65% and 80% or about 80% (w / w) of the concentrate. In one example, the polar solvent concentration range is between 65% or about 65% and 75% or about 75% (w / w) of the concentrate, or between 65% or about 65% and the 76% or about 76% by weight (w / w) of the concentrate, or between 68% or about 68% and 75% or about 75% by weight (w / w) of the concentrate.
In the provided methods for preparing the concentrates, the polar solvent (eg, water, propylene glycol, or glycerin) is added to the aqueous phase. In one example, the polar solvent is water, for example, purified water, such as water that has been purified before adding to the concentrated formula, for example, by charcoal filter, ion exchange, reverse osmosis, sterilization by UV and / or filtrations using a filter, for example a 50-100 micron filter. Typically, when a filter is used, it is an end-of-use filter that filters the water before it reaches the tank in the process provided. Alternatively, pre-filtered water can be added to the concentrates.
F. Preservatives and Sterilizers
In one example, the liquid concentrate provided further comprises one or more preservatives (or preservatives) and / or sterilizers. The preservative (s) can be included to improve the stability of the concentrate and compositions prepared by diluting the concentrate over time. Preservatives, particularly preservatives for food and beverages are well known. Any known preservative can be used in the compositions provided. Exemplary of preservatives that can be used in the provided compositions are oil-soluble preservatives, eg, benzyl alcohol, Benzyl Benzoate, Methyl Paraben, Propyl Paraben, antioxidants, eg, Vitamin E, Vitamin A Palmitate and Beta Carotene. Typically, a preservative is selected so that it is safe for human consumption, eg, in food and beverages, eg, a GRAS-certified and / or Kosher-certified preservative, eg, benzyl alcohol.
The preservative typically represents less than 1%, less than about 1%, 1%, or about 1% by weight (w / w) of the nanoemulsion liquid concentrate or between 0.1% or about 0.1%. and 1% or
ES 2 396 946 T3 about 1% by weight (w / w) of the concentrate, for example 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0, 6%, 0.7%,
0.725%, 0.75%, 0.8%, 0.9%, 1%, about 0.1%, about 0.2%, about 0.3%, about 0.4%, about 0.5% , about 0.6%, about 0.7%, about 0.8%, about 0.9%, about 1% by weight (w / w) of the liquid concentrate.
g. Emulsion stabilizers (co-emulsifier)
In one example, the liquid concentrates provided additionally contain one or more emulsion stabilizers (co-emulsifiers), which can be used to stabilize the liquid nanoemulsion concentrate and / or the aqueous compositions containing the dilute concentrates. In one example, the emulsion stabilizer increases the viscosity of the liquid concentrate. In one example, one or more emulsion stabilizers are added during formulation, after evaluation of an initial concentrate, particularly if the oil and aqueous phases of the initial concentrate (or the aqueous liquid dilution composition resulting from dilution of the initial concentrate ) it seems that they are separating. The addition of the emulsion stabilizer can prevent the separation of the oil and water phases.
Exemplary of an emulsion stabilizer that can be used in the provided compositions is a composition containing combinations of gums, for example gums used as emulsifying agents, for example, a combination containing one or more of xanthan gum, guar gum and alginate Sodium, for example, the emulsion stabilizer marketed under the trade name SALADIZER®, available from TIC Gums, Inc. (Belcamp, MD). Other gums can be included in the emulsion stabilizer, for example gum arabic and sugar beet pectin. Other similar gum blends can be used as emulsion stabilizers.
The emulsion stabilizer can be added to the aqueous phase, the oil phase, and typically to the aqueous and oil phase during the formation of the liquid concentrates. In one example, the emulsion stabilizer is added to the aqueous phase at a concentration such that it represents less than 1% or about 1% w / w of liquid concentrate. In one example, the emulsion stabilizer is added to the aqueous phase to a final concentration of between 0.1% or about 0.1% and 1% or about 1%, eg 0.1%. 0.12%, 0.13%, 0.14%, 0.15%, 0.16%, 0.17%, 0.18%, 0.19%, 0.2%, 0.25% , 0.3%, 0.31%, 0.32%, 0.33%, 0.34%, 0.35%, 0.36%, 0.37%, 0.38%, 0.39% , 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9% or 1% w / w of the liquid concentrate. In one example, the emulsion stabilizer is added to the oil phase in such a way that it represents less than 0.1% or about 0.1%, for example, between 0.01% or about 0.01% and 0.1% or about 0.1%, for example, 0.01%, 0.02%, 0.03%, 0.04%, 0.05%, 0.06%, 0.061%, 0.062%, 0.063%, 0.0635%, 0.07%, 0.08%, 0.09% or 0.1% by weight (w / w) of the concentrate. In one example, the emulsion stabilizer is added to the water phase and oil phase, for example, at a concentration within the oil and water phase concentration ranges noted above. In one of these examples, the emulsion stabilizer represents less than 1%, for example, between 0.01% or about 0.01% and 1% or about 1% (w / w) of the emulsion stabilizer , for example, 0.01%, 0.02%, 0.03%, 0.04%, 0.05%, 0.06%, 0.061%, 0.062%, 0.063%, 0.0635%, 0 .07%, 0.08%, 0.09%, 0.1%, 0.12%, 0.13%, 0.14%, 0.15%, 0.16%, 0.17%, 0 , 18%, 0.19%, 0.2%, 0.25%, 0.3%, 0.31%, 0.32%, 0.33%, 0.34%, 0.35%, 0 , 36%, 0.37%, 0.38%, 0.39%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9% or 1% by weight (w / w) of the liquid concentrate.
h. Non-polar solvents
In one example, the liquid concentrates additionally contain a non-polar solvent, eg, an oil. Typically, the nonpolar solvent is included in the composition in addition to the nonpolar active ingredient, and is used to dissolve the nonpolar active ingredient. In one example, the solvent is an oil that is not contained in the nonpolar active ingredient. When a non-polar solvent is included in the concentrate, it is typically used to dissolve the non-polar compound before mixing it with the other ingredients, for example, before mixing it with the oil phase ingredients. In one example, the use of a non-polar solvent reduces the size of the crystal and / or increases the transparency of the aqueous liquid dilution composition containing the dilute concentrate. Exemplary of the non-polar solvents that can be used in the concentrates provided are oils (in addition to the non-polar active ingredient) eg Vitamin E oil, linseed oil, CLA, Borage Oil, Dlimonene, Canola oil, Canola oil. corn, MCT oil, and oat oil. Other oils can also be used.

1. Aromas
In one example, the concentrate additionally contains one or more flavorings or flavoring agents, for example, any compound for adding flavor to the concentrate and / or aqueous dilution liquid composition containing the dilute concentrate, for example, the food or beverage containing the concentrate. Various aromas are well known. Any flavor can be added to the concentrates, for example, any flavor marketed by Mission Flavors, Foothill Ranch, Ca. Examples of flavors that can be used are flavors of fruits such as guava, kiwi, peach, mango, papaya, pineapple, banana, strawberry, currant, blueberry, orange, grapefruit, tangerine, lemon, lime and lemon-lime; cola scents, tea scents, coffee scents, chocolate scents, dairy scents, sarsaparilla and birch soda scents, methyl salicylate (wintergreen oil, sweet birch oil), citrus oils and other scents. Typically the flavors are safe and / or desirable for human consumption, for example GRAS or Kosher certified flavors. Exemplary flavoring agents that can be used in the compositions are lemon oil, for example, lemon oil sold by Mission Flavors, Foothill Ranch, CA; and GRAS certified 99% D-limonene, available from Florida Chemical, Winter Haven, FL. Typically, the flavor is added, using the methods provided, to the nanoemulsion concentrates after combining the oil and water phases. Alternatively, the flavor (s) can be added to the aqueous and / or oily phase directly.
Typically, the concentration of the flavoring agent added to the concentrates provided is less than 5% or about 5%, typically less than 1% or about 1%, for example 0.1%, 0.2%, 0, 3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 0.37%, or 0.525%.
j. PH adjusters
In one example, one or more pH adjusters are added to the provided concentrates, typically to the emulsion that is formed after combining the water and oil phases according to the provided methods. In particular, the pH adjuster is used in compositions containing water. Alternatively, the pH adjuster can be added, at an appropriate concentration to achieve a desired pH, to the oil phase and / or the aqueous phase. Typically, the pH adjuster is added to adjust the pH of the concentrate within a range of 2.0 or about 2.0 to 4.0 or about 4.0. One or more of a plurality of pH adjusting agents can be used. Typically the pH adjusting agent is safe for human consumption, eg GRAS certified. An exemplary pH adjuster is citric acid, eg, citric acid available from Mitsubishi Chemical, Dublin, OH.
Typically, the concentration of the pH adjuster added to the concentrates provided is less than 5% or about 5%, typically less than 1% or about 1%, eg 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 0.28%, or 0.19%.
2. Powder forms of the compositions
The compositions can also be provided in powder form, ie, powder that is prepared by converting the provided nanoemulsion concentrates into a powder, using one of several well-known methods (eg, spray drying and / or milling). Powdered compositions include, but are not limited to, coated or uncoated swallowable or chewable tablets, dry powders in hard or soft gelatin capsules, and dry powders in single or multi-use containers for reconstituted suspensions or sprinkles. Preferable solid dosage forms are coated or uncoated swallowable or chewable tablets. Suitable methods for preparing powder compositions are well known in the art.
Additionally, the powder composition may further comprise at least one excipient. Excipients include, but are not limited to, diluents (sometimes referred to as fillers) including, for example, microcrystalline cellulose, mannitol, lactose, calcium phosphate, dextrates, maltodextrin, starch, sucrose, and pregelatinized starch; disintegrants including, for example, crospovidone, sodium starch glycolate, croscarmellose sodium, starch, pregelatinized starch, and sodium carboxymethyl cellulose; binders including, for example, starch, hydropropylcellulose, hydroxypropylmethylcellulose, pregelatinized starch, guar gum, alginic acid, acacia, sodium carboxymethylcellulose, and polyvinylpyrrolidone; emollients including, for example, colloidal silicon dioxide and talc; and lubricants / release agents including, for example, magnesium stearate, calcium stearate, stearic acid, sodium stearyl fumarate, glyceryl monostearate, hydrogenated vegetable oil, and talc. In a particular example, the excipients are selected from any one or more of maltodextrin and acacia.
The powder forms can be used for any convenient dosage amount of the nonpolar compound. Generally, the level of the nonpolar compound can be increased or decreased in accordance with the judgment of the physician, pharmacist, pharmaceutical scientist, or other person skilled in the art. The amount of the remaining non-active ingredients can be adjusted as needed.
ES 2 396 946 T3
Typically, the concentration of the excipients is within a concentration range of between 50% or about 50% and 85% or about 85%, for example, 50, 51, 52, 53, 54, 55, 56 , 57, 58, 59,
60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85 or greater,% by weight of the free-flowing powder.
The powder forms can be used for any convenient dosage amount of the nonpolar compound. Generally, the level of the nonpolar compound can be increased or decreased in accordance with the judgment of the physician, pharmacist, pharmaceutical scientist, or other person skilled in the art. The amount of remaining non-active ingredients can be adjusted as needed.
In one example, the powder form is a free-flowing powder. Free flowing powders can be obtained using techniques well known in the art, such that, but are not limited to, spray drying, freeze drying or absorption plating. In one example, to achieve a free flowing powder, the protein derivative is formulated with an excipient such as lactose or starch. For example, the formulation can be a spray-dried lactose formulation (see, for example, US Patent No. 4,916,163).
Methods for forming the powders include spray drying. Spray drying processes and spray drying equipment are generally described in Perry's Chemical Engineers' Handbook, pages 20-54 to 20-57 (Sixth Edition 1984). More details on spray drying processes and equipment are reviewed by Marshall, Atomization and Spray-Drying, 50 Chem. Eng. Prog. Monogr. Series 2 (1954), and Masters, Spray Drying Handbook (Fourth Edition 1985). Methods for spray drying are well known (see, for example, US Patent No. 5,430,021; 6,534,085 and US Application Publication No. US2007 / 0184117). In general, spray drying is used to dry a heated liquid by passing it through hot gas. One or more spray nozzles are used to atomize the liquid in a cooling tower or chamber. As the material is atomized (pulverized) the surface tension causes a uniform spherical particle to form, which is passed through the cooling chamber and hardens into a solid intact sphere. The spray-dried particles can be between or about 0.5 microns and or about 100 microns, and typically are less than or about 10 microns, typically less than or about 5 microns, and typically less than or about or or about 1 micrometer.
Methods are provided for spray drying liquid nanoemulsion compositions to form powder compositions. In spray drying methods, liquid nanoemulsion compositions can be heated, for example, to a temperature between or about 100 (37.777 ° C) and or about 150 ° F (65.555 ° C), typically between 110 ° F (43,333 ° C) and 140 ° F (60 ° C), for example, from or about 110 (43,333 ° C), 115 (46,111 ° C), 120 (48,888 ° C), 125 (51,666 ° C), 130 (54.444 ° C), 135 (57.222 ° C) or 140 ° F (60 ° C). The compositions can be mixed while heating, such as with any of the mixers described herein, eg, homogenizers (eg, reversible homogenizers and piston-actuated homogenization).
For spray drying, one or more excipients are mixed with a polar solvent, typically water, and heated, for example, to a temperature between or about 100 ° F (37.777 ° C) and or about 150 ° F ( 65,555 ° C), typically between 110 ° F (43,333 ° C) and 140 ° F (60 ° C), for example, from or about 110 (43,333 ° C), 115 (46,111 ° C), 120 (48,888 ° C ), 125 (51.666 ° C), 130 (54.444 ° C), 135 (57.222 ° C) or 140 ° F (60 ° C). In one example, the excipient is mixed with water in an amount of one part excipient (by weight) to two parts water (by weight). The excipient-solvent mixture (eg, water) can be mixed while heating, eg, using any of the mixers described herein, eg, homogenizers (eg, reversible homogenizers and piston-actuated homogenization) while heating during mixing. The heated liquid nanoemulsion composition and the heated water-excipient mixture are then mixed together, such as by transferring one mixture to the other, for example, by any of the transfer means provided herein. Typically, the two mixtures are homogenized, for example, with a reversible homogenizer or a piston-driven homogenizer or any other homogenizer. The homogenized mixture is then subjected to spray drying using a spray drier.
They are exemplary of the spray dryers cyclone spray dryers. During spray drying with cyclone spray dryers, the homogenized mixture is pumped into a spray device where it degrades into small droplets. Upon contact with a stream of hot air, moisture is very quickly removed from the droplets while they are still suspended in the drying air. Drying dust is separated from humid air in cyclones by centrifugal action. The centrifugal action is caused by the large increase in air velocity when the mixture of particles and air enters the cyclone system. The denser dust particles are forced toward the walls of the cyclone while the lighter, moist air is directed away through the exhaust pipes. The dust settles at the bottom of the cyclone where it is removed through a discharge device. Sometimes the air transport ducts for the dry powder are connected with cooling systems that admit cold air for the transport of the product through transport tubes. Cyclone dryers have been designed for production schemes capable of drying batches of tons of
ES 2 396 946 T3 dust per hour.
As will be appreciated by one of ordinary skill in the art, the inlet temperature and outlet temperature of the spray dryer are not critical but will be of a level such that it provides the desired particle size, less than or about 1 micron and results in a powder that has a desired property. Typically, the ability of the free-flowing powder to produce a clear (or relatively clear) dilution liquid composition upon dilution in an aqueous medium is the desired property that is evaluated. In this sense, the inlet and outlet temperatures are adjusted depending on the melting characteristics of the liquid nanoemulsion components and the composition of the homogenized mixture of liquid nanoemulsion / excipient concentrate. The inlet temperature is between or about 60 ° C and or about 170 ° C, with outlet temperatures of or about 40 ° C up to or about 120 ° C. Preferably the inlet temperatures are from or about 90 ° C to or about 120 ° C and outlet temperatures are from or about 60 ° C to or about 90 ° C. The flow rate used in spray drying equipment will generally be from or about 3 ml per minute to at or about 15 ml per minute. The air flow of the atomizer will vary between values of or approximately 25 l per minute up to or approximately 50 l per minute. Commercially available spray dryers are well known to those of skill in the art and suitable accessories for any dispersion can be readily determined by one of ordinary skill in the art without undue experimentation. Operating conditions such as inlet temperature and outlet temperature, flow rate, atomization pressure, drying air flow rate, and nozzle configuration can be adjusted according to the manufacturer's guidelines.
In some examples, the dry powder is stored in a capsule form or pressed into a tablet form. For use as tablets, the compositions typically contain multiple other excipients. These excipients include tablet disintegrants, such as cornstarch, emollients, such as silicon dioxide, and lubricants, such as magnesium stearate. Ordinarily these compositions contain minor amounts by weight of emollients and lubricants, eg, every two percent (2%) or less by weight. Tablet disintegrators are optionally present and, if present, are included in amounts sufficient to ensure that the tablet disintegrates upon ingestion. Accordingly, materials such as cornstarch are employed at concentrations of from about zero to about 30 percent by weight of the composition.
Free-flowing powders can also be used to deliver the active agent by inhalation using a dry powder inhaler. Such dry powder inhalers typically deliver the active agent as a free-flowing powder that disperses in a patient's air stream during inspiration. To get the free flowing powder in the active agent it is typically formulated with a suitable excipient such as lactose or starch. For example, such a dry powder formulation can be prepared, for example, by combining the lactose with the active agent and then dry combining the components. Alternatively, if desired, the active agent can be formulated without an excipient. The pharmaceutical composition is then typically loaded into a dry powder dispenser, or inhalation cartridges or capsules for use with a dry powder delivery device. Examples of dry powder inhaler delivery devices include Diskhaler (GlaxoSmithKline, Research Triangle Park, NC) (see, for example, US Patent No. 5,035,237); Diskus (GlaxoSmithKline) (see, for example, US Patent No. 6,378,519; Turbuhaler (AstraZeneca, Wilmington, Del.) (See, for example, US Patent No. 4,524,769); Rotahaler (GlaxoSmithKline) (see, for example, US Patent No. 4,353,365) and Handihaler (Boehringer Ingelheim). Other examples of suitable DPI devices are described in US Patent Nos. 5,415,162, 5,239,993, and 5,715,810 and references cited therein.

As described above, the liquid concentrates are formulated in accordance with the desired properties of the aqueous liquid dilution compositions containing the concentrates.
to. Transparency
In one example, aqueous dilution liquid compositions are clear dilution aqueous liquid compositions or non-turbid dilution aqueous liquid compositions, for example, as determined as described below, empirically or by measuring turbidity and / or particle size. . In another example, aqueous liquid dilution compositions are not transparent, or are not completely transparent. The liquids can be more or less transparent, or have the same transparency as another liquid, for example, an aqueous dilution liquid composition prepared according to the methods provided or a beverage, for example, a beverage that does not contain the diluted concentrate. The properties of liquid concentrates can affect the transparency of the liquid. A number of parameters can vary the transparency of the liquids, for example, the relative concentration of the surfactant, nonpolar compound and / or water; the type of non-polar ingredient; the concentration of the excipient (s) in the particular non-polar compound and the purity of the non-polar compound, for example, whether it has been standardized to high purity, or whether it is an extract or a filtered extract. For example, an aqueous liquid dilution composition prepared by diluting a concentrate containing a non-polar active ingredient that contains lecithin, for example, a high amount of lecithin, may be less transparent than one prepared with a concentrate containing a non-polar compound that does not contain lecithin. In another example, a liquid concentrate containing a nonpolar compound that is a filtered extract can produce a more transparent dilution aqueous liquid composition when diluted than a concentrate containing a crude extract.
ES 2 396 946 T3
i. Transparency determined by empirical evaluation
In one example, the transparency / turbidity of the dilution aqueous liquid composition containing the dilute concentrate is qualitatively evaluated, by observation. In one example, a liquid can be considered transparent if it does not have an opaque appearance and / or if there are no or very few particles visible when liquid is seen with the naked eye or if it is the same or substantially similar in transparency to another liquid, for example , a drink, for example water, fruit juice, soda or milk. In some cases, the aqueous liquid dilution composition is as clear or about as clear as water or another liquid, eg, a beverage. For example, the liquid (containing the liquid concentrate diluted in an aqueous medium, eg a beverage), may be as clear or about as clear as the aqueous medium that does not contain the liquid concentrate. In a related example, there is no substantial difference, for example, there is no observable difference between the aqueous liquid dilution composition containing the concentrate and the aqueous medium without the concentrate. A clear liquid is not necessarily colorless, for example, a yellow liquid that does not contain visible particles or opacity can be considered transparent. In another example, the liquid is transparent or partially transparent or substantially transparent if there are no visible crystals and / or if no ring formation is observed in the container containing the liquid.
ii. Transparency determined by particle size or number of particles
In another example, the transparency of the aqueous dilution liquid composition is evaluated by measuring the particle size and / or the number of particles in the liquid.
In one example, aqueous dilution liquid compositions have a particle size of less than 200 nm or less than about 200 nm, for example, 5, 10, 15, 20, 25, 26, 27, 28, 29, 30, 31 , 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 60, 70, 80, 90, 100, 110 , 120, 130, 140, 150, 160, 170, 180, 190 or 200 nm. In another example, the aqueous liquid dilution composition has a particle size less than 100 nm or about 100 nm, less than 50 nm or about 50 nm, or less than 25 nm or about 25 nm. Typically, the particle size of the aqueous liquid dilution composition is between 5 nm or about 5 nm and 200 nm or about 200 nm, or between 5 nm or about 5 nm and 50 nm or about 50 nm.
Typically, the particle size of the provided aqueous dilution liquid composition containing the liquid concentrate containing the nonpolar compound is smaller than the particle size of a liquid containing the nonpolar compound (not formulated in a liquid concentrate ).
iii. Turbidity
In another example, the transparency of the liquid is evaluated and / or expressed using a turbidity measurement, eg, Nephelometric Turbidity Units (NTU), as measured using the provided methods, described below.

3. General methods for preparing liquid nanoemulsion concentrates
In general, the methods for preparing the concentrates include the steps for generating phases (eg, the oil phase (s) and the aqueous phase (s)) and the steps for combining and emulsifying the phases, to form the liquid nanoemulsion concentrates. In some examples, the methods include additional steps, such as evaluation, addition of additional ingredients, packaging, and filtration. The methods provided can be performed using an experimental scale manufacturing process (typically for small batch sizes). Alternatively, the methods can be performed using a larger scale manufacturing process (typically for larger batch sizes). Each of the provided concentrates can be prepared using a large scale process or an experimental scale process. In one example, after the concentrate is first prepared using the experimental scale process, the method is scaled up to prepare larger amounts of the concentrate using the large scale processes. When concentrates are formulated according to the methods provided, the initial concentrate is typically prepared by an experimental scale procedure. In one example of the formulation methods, a selected formulation is then prepared using a large scale procedure. Any of the concentrates provided herein can be prepared by the methods provided using any of the manufacturing processes. Any method described in this document, when using an experimental scale method, can be scaled up for the production of the concentrates using the large scale processes.
In general, the methods for preparing liquid nanoemulsion concentrates include first generation steps, whereby one or more oil phases and one or more aqueous phases are produced. The generation of the aqueous phase and the generation of the oil phase are typically carried out in at least two different vessels, for example, an oil phase vessel and an aqueous phase vessel. Each of the generation steps typically includes a mixing step and a heating step, which can be performed simultaneously, sequentially in any order, or partially simultaneously.
To generate the aqueous phase, the aqueous phase ingredient (s) (eg, the polar solvent (eg, water, propylene glycol, glycerin, or other polar solvent) and, in some examples, additional aqueous phase ingredients) are added to an aqueous phase vessel. The ingredient (s) are mixed, typically using a conventional mixer, and heated, for example, using a heating apparatus. Typically, the ingredients of the aqueous phase are heated to a low heat temperature, for example, 60 ° C or about 60 ° C. To prepare the oil phase, the oil phase ingredients (eg, a nonpolar compound (s), surfactant (s), and, in some examples, another oil phase ingredient (s)) are added to an oil phase container. The oil phase ingredient (s) are mixed, typically using a conventional mixer, and heated, for example, using a heating apparatus. Typically the ingredients are heated to a low heat temperature, for example 60 ° C or about 60 ° C. The mixing / heating of the water and oil phase can be carried out simultaneously or sequentially in any order. In one example, the generation of the oil phase is carried out subsequent to the generation of the aqueous phase, for example, to preserve the non-polar active ingredient, for example, to prevent its oxidation. Typically both phases are heated to the desired temperature, eg, a low heat temperature, and / or until the ingredients dissolve, before combining the oil and water phases in a subsequent emulsion step.
In general, the methods additionally include an emulsion step. For the emulsion stage, the oil and water phases are combined, for example, using one or more transfer means. The oil and water phases are emulsified, typically with mixing, typically homogenizing, eg, using high shear to generate an emulsion (eg, the nanoemulsion liquid concentrate). The emulsion step can be carried out in the aqueous phase vessel, oil phase vessel or a different vessel.
Typically, during the emulsion step, the forming emulsion is cooled, eg, rapidly cooled, eg, using one or more cooling apparatus. Typically, the cooling stage is performed simultaneously with the emulsifying stage. In one example, cooling is carried out until the emulsion reaches a temperature between 25 ° C or about 25 ° C and 43 ° C or about 43 ° C.
The methods may include additional steps, eg, evaluation steps, steps to add additional ingredients, purification steps (eg, filtration), and / or packaging / containment steps, as detailed below.

Typically, the aqueous phase ingredients are weighed and / or measured, for example, using one or more balances (e.g., one or more of the balances described herein), prior to addition to the aqueous phase container (e.g. example, any container described in this document). In one example, the amount of each ingredient to be added to the aqueous phase container will be determined according to the methods provided for formulating the ingredients.
ES 2 396 946 T3 concentrates. Typically, the desired concentration by weight (w / w) of the final nanoemulsion concentrate is used to calculate the amount of each water phase ingredient that is added to the water phase container. Alternatively, desired volume by weight, volume by volume, or weight by volume can be used to calculate the correct amount of an ingredient to measure and add to the container.
In one example, when water is the polar solvent, impurities in the water, for example urban water, are removed using one or more purifiers (for example, one or more purifiers as described herein) above, prior to Add the water to the aqueous phase tank. In one example, the water is purified by passing through and using the following purifiers sequentially: a carbon filter, an ion exchange filter, a reverse osmosis purifier, and an end-point filter, for example, a 100 micron end point filter, prior to adding to aqueous phase vessel.
Typically, the aqueous phase ingredient (s) are mixed in the aqueous phase container using a conventional mixer (for example, any of the conventional mixers described herein), and heated, typically simultaneously or, in part, simultaneously, using a heating apparatus (eg, any of the heating apparatus described in this document). Typically, the aqueous phase is heated so that the ingredients in the aqueous phase reach a low heat temperature, for example, between about 45 ° C or about 45 ° C and 85 ° C or about 85 ° C, for example, 45 , 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70 , 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84 or 85 ° C, typically 60 ° C or 60 ° C, for example, to prevent oxidation of non-polar ingredients and / or maintain ingredient stability. Typically, mixing and / or heating the aqueous phase ingredients is continued in the aqueous phase vessel, for example, before combining the aqueous phase and the oil phase. In one example, the aqueous phase is mixed and / or heated until the ingredients dissolve in the aqueous phase. Typically, the temperature of the water phase is maintained by mixing before combining the oil and water phases.
i. Ingredients of the aqueous phase
The aqueous phase includes one or more polar solvents such as water, diols, such as propylene glycol, and sugar alcohols such as glycerin, and in some examples other aqueous phase ingredients are included. Typically, the aqueous phase ingredients are hydrophilic and / or amphipathic ingredients of the liquid nanoemulsion concentrate. For example, oils and other lipophilic ingredients are typically not added to the aqueous phase. Certain ingredients, eg ingredients having hydrophobic and hydrophilic moieties, eg surfactants and co-surfactants, can be added to either the oil phase or the water phase, or to the oil phase and the water phase. Exemplary aqueous phase ingredients include, but are not limited to, polar solvents, eg, water, typically filtered water, propylene glycol, glycerin, and other diols; emulsion stabilizers; pH adjusters, for example phosphoric acid and / or citric acid; aromas; surfactants, co-surfactants, eg, phosphatidylcholine and / or quillaja saponaria; and preservatives.
The ingredients of the aqueous phase can be added to the aqueous phase simultaneously and / or sequentially, in a specific order. In one example, one or more aqueous phase ingredients are added first and heated, prior to the addition of the additional ingredient (s). In one example, when the ingredients of the aqueous phase include a polar solvent and an emulsion stabilizer, these ingredients are added sequentially, in the following order: 1) polar solvent; 2) emulsion stabilizer. In one example, when the aqueous phase ingredients include water and an emulsion stabilizer, these ingredients are added sequentially, in the following order: 1) water, 2) emulsion stabilizer. In another example, when the aqueous phase ingredients include a surfactant, a polar solvent (eg, water), and an emulsion stabilizer, these ingredients are added to the aqueous phase container sequentially, in the following order: 1) surfactant; 2) polar solvent (eg water); 3) emulsion stabilizer. Alternatively, the ingredients of the aqueous phase can be added in any order. Typically, when the aqueous phase includes a surfactant, particularly when the surfactant is a surfactant that is solid at room temperature, for example, polyethylene glycol tocopherol succinate surfactant, the surfactant is the first ingredient in the aqueous phase added to the phase container. watery. Typically, when the aqueous phase ingredients include an emulsion stabilizer, the emulsion stabilizer is the last ingredient added to the aqueous phase container.
b. Generation of the oil phase
Typically the oil phase ingredient (s) are weighed and / or measured, for example, using one or more balances (e.g., one or more of the balances described herein), prior to addition to the oil phase container ( for example, any of the containers described in this document). In one example, the amount of each oil phase ingredient to add is determined according to the methods provided for formulating the concentrates. Typically, the desired concentration by weight (w / w) of the final nanoemulsion concentrate is used to calculate the amount of each oil phase ingredient that should be added to the oil phase container. Alternatively, the volume by weight, volume by volume or weight by volume can be used to calculate the correct amount of an ingredient to measure and add to the container.
ES 2 396 946 T3
Typically, the oil phase ingredients are mixed in the oil phase container using a conventional mixer (for example, any of the conventional mixers described herein) and heated, typically simultaneously, using a heating apparatus (for example, any of the heating devices described in this document). Typically, the oil phase is heated so that it reaches a low heat temperature for example between 45 ° C or about 45 ° C and 85 ° C or about 85 ° C, for example 45, 46, 47, 48, 49 , 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74 , 75, 76, 77, 78, 79, 80, 81, 82, 83, 84 or 85 ° C, typically 60 ° C or 60 ° C, for example, to avoid oxidation of the non-polar ingredients and / or maintain the stability of the ingredients. In one example, one or more of the oil phase ingredients are mixed and heated according to the methods provided prior to the addition of the remainder of the oil phase ingredients. For example, the nonpolar compound can be mixed and heated with one or more solvents, for example an oil, for example linseed oil and / or Vitamin E oil, until the nonpolar compound dissolves in the oil, before from the addition of the other oily ingredients. Typically, the oil phase ingredients are mixed in the oil phase container until dissolved. Typically, the temperature of the oil phase is maintained with the mixture before combining the oil and water phases.
In some examples the oil and / or aqueous phase may be prepared in more than one container, for example, by mixing one or more of the aqueous phase ingredients in one container and mixing one or more other oil ingredients in another container. In this example, the mixed oil phase ingredients in the separate containers may be mixed together prior to emulsifying with the aqueous phase or, alternatively, they may be added separately during emulsification to the aqueous phase.
i. Oil phase ingredients
The oil phase includes the nonpolar compound, eg, the nonpolar active ingredient and, in some examples, other ingredients of the oil phase. Typically, the oil phase ingredients include one or more lipophilic and / or amphipathic ingredients of the liquid nanoemulsion concentrate. Oil phase ingredients typically do not include aqueous ingredients or hydrophilic ingredients. Certain ingredients, eg ingredients having hydrophobic and hydrophilic moieties, eg surfactants and co-surfactants, can be added to either the oil or water phase, or the oil and water phase. Exemplary of ingredients used in the oil phase of the concentrates provided are non-polar compounds, eg, non-polar active ingredients, including any of the non-polar active ingredients provided herein, emulsion stabilizers, pH adjusters, for example , phosphoric acid and / or citric acid; surfactants; co-surfactants, for example phosphatidylcholine and / or quillaja saponaria; preservatives and oils, eg solvents and other oil phase ingredients.
The oil phase ingredients can be added to the oil phase simultaneously and / or sequentially, for example, in any order or in a specific order. In one example, one or more oil phase ingredients are added first and heated, prior to the addition of an additional ingredient or ingredients. In one example, when the oil phase ingredients include a surfactant, a preservative, a solvent, a cosurfactant, and a nonpolar compound, these ingredients are added sequentially, in the following order: 1) surfactant; 2) preservative; 3) solvent; 4) co-surfactant; 5) nonpolar compound; and 6) emulsion stabilizer. In another example, when the oil phase ingredients include a surfactant, a preservative, and a nonpolar compound, the ingredients are added sequentially in the following order: 1) surfactant; 2) preservative; 3) nonpolar compound. In another example, when the oil phase ingredients include a surfactant, a preservative, a nonpolar compound, and an emulsion stabilizer, the ingredients are added sequentially in the following order: 1) surfactant, 2) preservative, 3) nonpolar compound. polar and 4) emulsion stabilizer. Alternatively, the oil phase ingredients can be added in a different order, eg any order. Two or more ingredients of the oil phase can be added simultaneously.
Typically, when the oil phase includes a surfactant, particularly when the surfactant is a surfactant that is solid at room temperature, for example, polyethylene glycol tocopherol succinate surfactant, the surfactant is the first oil phase ingredient added to the phase vessel. oily. Typically, when the oil phase ingredients include an emulsion stabilizer, the emulsion stabilizer is the last ingredient added to the oil phase container. Typically, the nonpolar compound is either of the last ingredient added to the oil phase, or is added immediately prior to the addition of the emulsion stabilizer, which is the last ingredient added to the oil phase container.
c. Combination and emulsion of the oil phase and the water phase
In general, in the methods, after generation of the oil phase and the water phase, the oil and water phases are combined, for example, using one or more transfer means (for example, any of the transfer means described in this document). The combined phases are emulsified, eg, by mixing, eg, homogenization, to form an emulsion (eg, a liquid nanoemulsion concentrate). Typically, the phases are mixed during the blending and emulsifying steps, eg, using a homogenizer (eg, any of the homogenizers described herein). In one example,
ES 2 396 946 T3 the oil and water phases (eg the emulsion being formed) are further cooled, eg rapidly cooled during the emulsion and / or blending steps.
i. Combination of the oil and water phases
To emulsify them, the oil and water phases are first combined, typically by transfer, using one or more transfer media (eg, any of the transfer media described herein). In one example, the oil phase is transferred to the water phase vessel. In another example, the aqueous phase is transferred to the oil phase vessel. In another example, a plurality of the oil phases or aqueous phases are transferred to an aqueous phase or oil phase vessel. In another example, the aqueous phase (s) and the oil phase (s) are transferred to another container, eg, an emulsion container.
Any transfer medium can be used to combine the phases. For example, any means for transferring the contents of one container to another container as described above, for example transfer pumps and associated equipment, for example sanitary fittings, hoses and / or ball valves; and manual transfer means, for example pouring and / or pipetting means or other known transfer means. In some examples, the phases are kept clean, eg, sterile during transfer, eg, using transfer media with sanitary fittings and / or by combining the phases in a sterile environment.
ii. Emulsion of the oil and water phases
Simultaneously with and / or subsequent to combining the phases, the phases are mixed (eg, homogenized), eg, using a homogenizer (eg, any of the homogenizers described) to form an emulsion. Typically, the emulsion is made in the container containing the combined liquids, eg, the oil phase or the aqueous phase container. For this emulsifying step, the oil and water phases are mixed, for example after the combining step, typically during and after the combining step, using a mixer that is capable of emulsifying liquids, for example a homogenizer, for example, a reversible homogenizer. Typically liquids are homogenized using the mixer (eg homogenizer) at a low speed, eg low rpm, eg between 850 rpm or about 850 rpm and 1200 rpm or about 1200 rpm, eg 850, 900, 950, 1000, 1050, 1100, 1150 or 1200 rpm.
The liquids are typically mixed, continuously or intermittently, until the liquids emulsify, for example, into a nanoemulsion. In one example, the mixing speed is maintained to emulsify the oil and water phases. In one example, the mixer baffle plate is adjusted, for example by moving the baffle plate further down into the mix or further up out of the mix, to control the type of mix, for example to change flow descending to ascending flow and vice versa, during mixing of the emulsion. In another example, the homogenizer can be adjusted to increase or decrease the shear or to maintain the shear at a particular speed. The methods for homogenizing the oil and water phases are well known and other methods can be used to homogenize the oil and water phases in the methods.
iii. Cooling
Typically, the emulsion is cooled during mixing, for example, by quenching. In one example, the emulsion is cooled to promote emulsion stability and phase emulsification, eg, avoiding or minimizing oxidation, eg, oxidation of the nonpolar compound. Cooling, eg quenching, is typically accomplished using one or more cooling apparatus, eg, any of the cooling apparatus described herein or any known cooling apparatus. In one example, the cooling apparatus is a recirculating cooler. In another example, the cooling apparatus is a water bath or an ice bath. In one example, when the apparatus is a recirculating cooler, the fluid in the container that is used for the emulsion stage is recirculated through the cooler, then back to the container, to rapidly cool and maintain the temperature of the mixture during mixing. . Typically, the forming emulsion is mixed and cooled until the phases emulsify and the temperature reaches between 25 ° C or about 25 ° C and 43 ° C or about 43 ° C, for example 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39; 40, 41, 42 or 43 ° C. Typically, when cooling is quenching, the temperature is reached in less than 2 hours or about 2 hours, typically less than 1 hour or about 1 hour, for example, in at least between 30 minutes or about 30 minutes and 60 minutes or about 60 minutes, for example 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51 , 52, 53, 54, 55, 56, 57, 58, 59 or 60 minutes.
Once the oil and water phases have been emulsified, thereby forming an emulsion, for example a liquid nanoemulsion concentrate, the emulsion can be used, for example, in the dilution methods provided to prepare a liquid dilution composition, for example, a drink, which contains the concentrate. Alternatively, one or more additional steps can be performed prior to using the concentrate.
ES 2 396 946 T3
d. Additional stages
Typically, one or more additional steps are performed, after emulsifying the phases, before using the concentrate. For example, the emulsion can be evaluated (eg, by measuring the pH and / or temperature of the concentrate). In another example, one or more additional ingredients can be added to the emulsion. In another example, the nanoemulsion concentrate is transferred to a containment container or packaging container, eg, a containment / packaging container, eg, a containment / packaging tank. In another example, the nanoemulsion is purified, eg filtered, before use. In one example, the addition of additional ingredients, evaluation, and / or purification can be done in the containment / packaging container. Other additional steps can be performed prior to use.
i. Additional ingredients
In one example, additional ingredients, for example pH adjusters and / or flavors, may be added to the emulsion after it is formed. In one example, citric acid and / or phosphoric acid is added to adjust the pH, for example, until the pH reaches a pH between 2.5 and 3.5, typically between 2.6 or about 2.6 and 3, 2 or about 3.2, for example 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, or 3.2. In another example, one or more flavors are added to the concentrate, for example, to enhance the taste and / or odor of the concentrate and / or beverages containing the concentrate. In another example, an additional polar solvent, eg water, may be added to the emulsion, eg in the case of evaporation to bring the concentrate to the appropriate volume. Other additional ingredients can also be added to the emulsion. Typically, additional ingredients are added to the container containing the emulsion, eg, the aqueous phase container, the oil phase container, the emulsion container, or another container, eg, a containment / packaging container. Typically, the emulsion is mixed (eg, using any of the described mixers, typically conventional mixers) while the additional ingredients are added.
ii. Concentrate evaluation
Typically, the concentrate is evaluated prior to use. Typically, pH and / or temperature are measured, for example, using a pH and temperature meter. In one example, pH and / or temperature are evaluated after additional ingredients have been added. In one example, additional ingredients can be added to adjust the parameters after evaluation.
iii. Concentrate filtration
In one example, the concentrate is purified (eg, with any of the purifiers described), eg, using a final product filter, before using the concentrate, eg, before diluting the concentrate in an aqueous medium.
Four. Experimental scale procedure
In one example of the methods for preparing the liquid nanoemulsion concentrates, the method steps are performed using an experimental scale manufacturing process that is performed on a bench, counter, table, and other surface. Typically, the experimental scale process is used to prepare emulsions that have volumes relatively smaller than those prepared with the large scale processes, for example, volumes less than 1 or about 1 or less than 1 gallon (3.79 liters) or about 1 gallon (3.79 liters), for example, less than about 500 ml, for example, 1000, 900, 800, 700, 600, 500, 450, 400, 350, 300, 250, 200, 150, 100, 50 or less.
For the experimental scale process, the equipment is typically compact enough to be used on top of a counter or other similar surface, typically compact enough to be moved, for example, to be moved, for example, lifted by the expert using the methods. . For example, the containers, for example, aqueous phase containers, oil phase containers, containment containers and packaging containers are typically experimental scale containers, for example, flasks, beakers, vials, measuring containers, flasks and / or other containers of experimental scale. In one example, the vessels in the experimental scale process are a Pyrex® beaker. Typically, the mixers are mixers that can be used in experimental scale vessels, for example, conventional mixers including hand mixers, stir bars, stir bars, magnetic mixers and top mixers, for example mechanical and / or electric top mixers and / or mixers. or other mixers that can be used in the containers. Exemplary of suitable experimental scale mixers are conventional mixers, for example conventional mixers marketed by IKA®, for example IKA® top mixers, for example models No. RW-14 Basic and RE-16S, which are laboratory mixers and which can be used to mix ingredients, for example to generate the oil and water phases. Also exemplary of suitable experimental scale mixers are homogenizers, eg, reversible homogenizers, including the Arde Barinco reversible homogenizer, Model No. CJ-4E, which can be used to emulsify the phases. Typically, heating appliances are those that can
ES 2 396 946 T3 be used with experimental scale containers, eg hot plates. Cooling apparatuses are typically apparatus suitable for use with smaller experimental scale vessels, eg ice baths and / or water baths in which the vessels can be placed, eg for rapid cooling. The evaluation means used in the experimental scale process, for example temperature and / or pH meters, typically may be capable of being put into the experimental scale vessels.
In general, for experimental scale processes, the oil phase and the water phase are generated by mixing and heating separately in experimental scale vessels, for example, flasks, beakers, vials, measuring containers, flasks and / or other containers. on an experimental scale. Mixing is typically performed using an appropriate experimental scale mixer, for example a conventional mixer, such as a hand mixer, stir bar, stir bar, magnetic mixer and / or top mixer, for example the commercially available IKA® mixer. For example, the IKA® top mixers, for example, models N ° RW-14 Basic and RE-16S, which are laboratory stirrers. Typically, the heating of the oil and water phases is carried out using a heating apparatus appropriate for the experimental scale method, for example, a heating apparatus on which one or more of the containers can be placed, for example, a hot plate. . To combine the oil phase and the aqueous phase, one or more phases, typically one phase, is typically transferred manually to another container eg, by pouring, pipetting, and / or other manual transfer means. To emulsify the oil and water phases, a reverse homogenizer is typically used. To cool the forming emulsion, for example to rapidly cool the emulsion, a cooling apparatus suitable for the experimental scale method is typically used, for example a cooling apparatus in which the container can be placed on top of or inside the container. For example, a water bath or an ice bath.
5. Large-scale manufacturing processes
The methods for preparing the liquid nanoemulsion concentrates can be carried out using a large-scale manufacturing process. A large-scale manufacturing process is typically used when the liquid nanoemulsion concentrate being prepared has a relatively larger volume than a concentrate being prepared by the experimental-scale process, for example, volumes greater than 1 or about 1 or more. greater than 1 gallon (3.79 liters) or about 1 gallon (3.79 liters), for example, greater than about 500 ml, for example, at least 0.5 l, 1 l, 2 l or 1 (3.79 liters), 2 (7.57 liters), 3 (11.36 liters), 4 (15.14 liters), 5 (18.93 liters), 6 (22.71 liters), 7 (26.0 liters), 8 (30 , 28 liters), 9 (34.07 liters), 10 (37.85 liters), 11 (41.64 liters), 12 (45.42 liters), 13 (49.21 liters), 14 (53.00 liters), 15 (56.78 liters), 16 (60.57 liters), 17 (64.35 liters), 18 (68.14 liters), 19 (71.92 liters), 20 (75.71 liters) , 21 (79.49 liters), 22 (83.28 liters), 23 (86.06 liters), 24 (90.85 liters), 25 (94.63 liters), 26 (98.42 liters), 27 (102.21 liters), 28 (105.99 liters), 29 (109.78 liters), 30 (113.56 liters), 40 (151.42 liters), 50 (189.27 liters), 60 (227.12 liters), 70 (264 , 98 liters), 80 (302.83 liters), 90 (340.69 liters), 100 (368.54 liters), 150 (567.81 liters), 200 (757.08 liters), 250 (946.35 liters), 300 (1135.62 liters), 350 (1324.89 liters), 400 (1514.16 liters), 450 (1703.43 liters), 500 (1892.70 liters), 550 (2081.97 liters) , 600 (2271.24 liters), 650 (2460.51 liters), 700 (2649.78 liters), 800 (3028.32 liters), 900 (3406.86 liters), 1000 (3785.40 liters) or more gallons.
In general, large-scale manufacturing processes are performed with equipment that is compatible with these higher volume batches (batch sizes). For example, vessels used in large-scale processes are typically tanks, e.g., water-jacketed tanks, which are equipped with water jackets that can be used as heating apparatus to heat the oil and water phase ingredients during the generation of the oil and water phases. Water jackets are typically controlled by control panels. Similarly, the transfer means used in the large-scale process typically include transfer pumps and associated accessories, eg, ball valves and hoses. Exemplary of mixers used in large-scale processes are conventional mixers (for example, mounted mixers, for example LIGHTNIN® mixers, for example, the Model XJC117 (a fixed-mount, gear-driven, high-flow mixer). and model ND2)). An exemplary large-scale process is set forth in Figure 1 and described in this section, below. The methods provided for preparing the concentrates can be performed using this exemplary large-scale process, or any variation of the large-scale process, for example, eliminating one or more steps from the exemplary process, adding one or more steps in accordance with the method and / or by substituting steps and / or equipment according to the methods described in this document.
Figure 1 sets forth an exemplary large-scale process 100 for preparing the liquid concentrate. In this example, the polar solvent is water. This exemplary large-scale process includes the following stages:
to. Water treatment
As indicated herein, the polar solvent can include water (including purified water) and other polar solvents, for example, glycerin and propylene glycol. In the example illustrated in Figure 1, the polar solvent is water 101 (e.g. urban water), which is purified prior to addition to the aqueous phase vessel by passing the water through the following purifiers, sequentially, in the following order: a carbon filter 105, an ion exchange kit 106, a reverse osmosis kit 107, a 100 micron end-point filter 108, and a 50 micron point-of-use filter 109.
ES 2 396 946 T3
b. Generation of the aqueous phase and the oil phase:
As described above, for the generation of the aqueous phase, the polar solvent and any other ingredients of the aqueous phase, typically are weighed and / or measured and added to the aqueous phase container and mixed, using a conventional mixer or another mixer, such as a homogenizer or other mixer described in this document and are typically heated during mixing, whereby the aqueous phase is generated with mixing and heating, typically at low heat (eg 60 ° C, 70 ° C, 71 ° C), according to the methods provided. In the example of the large-scale manufacturing process set forth in Figure 1, the aqueous phase vessel is an aqueous phase tank 103, which is a water jacketed tank. In the example illustrated in Figure 1, the ingredient (s) of the aqueous phase are mixed using a conventional mixer 111, for example, a LIGHTNIN® mixer (for example, model # XJC117, a gear-driven high flow mixer , fixed mounting), fixed to the tank, for example, mounted on the top of the tank. In the example illustrated in Figure 1, the heating apparatus used to heat the ingredients of the aqueous phase is the water jacket of the water jacket tank; the temperature in the water jacket is controlled through a control panel.
As described above, for the generation of the oil phase, the oil phase ingredients are typically weighed and / or measured, and added to the oil phase container and mixed, using a conventional mixer or other such mixer. as a homogenizer or other mixer described herein, and are typically heated during mixing, whereby the oil phase is generated with mixing and heating, typically with low heat (e.g. 60 ° C), according to the methods provided. In the example of the large scale manufacturing process set forth in Figure 1, the oil phase vessel is a water jacketed oil phase tank 102. In the example illustrated in Figure 1, the oil phase ingredients are mixed using a conventional 111 mixer, for example, a LIGHTNIN® mixer (for example, model ND2), attached to the oil phase tank, for example, mounted in the tank. In the example illustrated in Figure 1, the heating apparatus used to heat the oil phase ingredients is the water jacket of the water jacketed oil phase tank; the temperature in the water jacket is controlled by a control panel.
c. Combination and emulsion of the phases
As described in this document, once the oil and water phases reach the desired temperatures (for example, 60 ° C, 70 ° C, 71 ° C or other temperature), after the ingredients of the oil phase and / or aqueous phase, and optionally after cooling of one of the phases, for example cooling of the aqueous phase to 60 ° C according to the methods provided, the oil and water phases are combined by transfer and are typically emulsified by homogenization. In one example, the transfer is performed slowly to avoid build-up in the forming emulsion, such as by periodically stopping the transfer while continuing to mix the emulsion, or combining the phases slowly with the mixture. In the example of the large-scale manufacturing processes illustrated in Figure 1, phase combining is effected by transferring the oil phase to the aqueous phase container through transfer means 112, including a transfer pump (e.g., a Teel pump, model 2P377B, available from Granger, Inc.), sanitary fittings, a transfer tube or tubes (for example, food grade tubing marketed by Sani-Tech West) and a ball valve (s). Alternatively, the aqueous phase can be transferred to the oil phase. In the example set forth in Figure 1, to begin the blending / emulsifying steps, a homogenizer 110 (eg, an Arde Barinco, Inc. reversible homogenizer), mounted in the oil phase tank, is connected, for example, to 850-1200 rpm. The ball valves are then opened and the transfer pump is switched on, thus beginning the transfer of the liquid oil phase to the water phase tank through a transfer tube or tubes. As the phases are combined, the mixture is homogenized by continuous mixing with homogenizer 110.
In some examples of the large-scale manufacturing process, to avoid lumps, the pump is stopped periodically (eg by turning off the pump), while continuing to mix with the mixer, during emulsification. In one aspect of this example, this method is used to avoid lumps when the polar solvent is a solvent other than water, such as propylene glycol or glycerin. During mixing, the homogenizer can be adjusted, for example, by adjusting the baffle plate over the homogenizer to achieve and maintain an emulsion, for example, by moving the baffle plate further into the emulsion formation and / or further out of the emulsion in training. In one example, the shear rate is set to a rate where the oil phase can be seen exiting the top of the mixer. In one example, this setting is used when the polar solvent is a solvent other than water, such as propylene glycol or glycerin.
d. Cooling
As described herein, the forming emulsion typically cools, typically cools rapidly during the emulsion step. In the large-scale process, as shown in the example illustrated in Figure 1, quenching is typically accomplished by repeatedly passing the forming emulsion through a recirculating cooler 115 (for example, Model No. OC-1000 RO, marketed by Turmoil, West
ES 2 396 946 T3
Swanzey, NH), which is attached to the aqueous phase tank. Homogenization continues during the cooling stage, for example between 850 and 1200 rpm. Cooling continues, for example, until the temperature of the emulsion reaches between or about 25 ° C and about 43 ° C, such as between or about 25 ° C and about 35 ° C, between or about 35 ° C and about 43 ° C, or at about 40 ° C. Typically, the quench is done between or about 30 and in or about 60 minutes.
and. Additional stages
As described herein, additional steps can be performed after the emulsion is formed. In the example of the large-scale manufacturing process set forth in Figure 1, additional steps include transferring the emulsion, through a transfer means 112, which includes a transfer pump (e.g., a Teel pump, model 2P377B, sold by Granger, Inc.), sanitary fittings, a transfer tube or tubes (for example, food grade tubes sold by SaniTech West), and a ball valve or valves, to a containment / packaging tank 104. The transfer is done by connecting the transfer pump and opening the ball valves. Additional ingredients, eg, pH adjusters, may be added, eg, while controlling the pH, sufficient to bring the nanoemulsion to an appropriate pH, eg, between about 2.6 and 3.2. Flavors can also be added. The additional ingredients are mixed into a concentrate using a conventional mixer 111. The addition and mixing of additional ingredients and / or evaluation can be performed in the containment / packaging tank 104; alternatively, it can be done prior to transfer to the containment / packaging tank, eg, in tank 103 of the aqueous phase.
Variations of this exemplary large-scale process (Figure 1) can also be performed using the methods, including any of the variations described herein for preparing the concentrates. For example, by elimination and / or modification of one or more stages and / or equipment, according to the general methods described in this document.
D. Methods for preparing the liquid dilution compositions containing the dilute concentrates
Also described herein are methods for diluting liquid nanoemulsion concentrates to prepare liquid dilution compositions, typically aqueous liquid dilution compositions, containing nonpolar compounds. Generally, the nanoemulsion concentrate is diluted in an aqueous medium, for example, a beverage, for example, soda, water, milk, juice, health drinks, nutritional drinks, nutritional supplements, or other aqueous food or beverage. The concentrate and the aqueous medium can be mixed, for example, by stirring and / or combining or by any known mixing means. The concentrate is dispersed in the aqueous medium to form an aqueous dilution liquid composition, for example, a clear or partially clear aqueous dilution liquid composition. The aqueous liquid dilution composition can be evaluated, for example, to evaluate the transparency, taste, odor and / or stability of the liquid.
In one example, the liquid nanoemulsion concentrate is diluted in the aqueous medium, eg, water, with heating of the aqueous medium, eg, heating of the aqueous medium, eg, to at least 40 ° C or at least about 40 ° C. , for example, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50 or more ° C, for example, 48.9 ° C. In this example, the liquid nanoemulsion concentrate is added at an appropriate dilution, as described herein, to the heated aqueous medium, and stirred until dispersed or dissolved in the solution. The resulting liquid dilution composition can then be cooled, eg, to room temperature eg 25 ° C or about 25 ° C. After dilution, the aqueous liquid dilution composition can be packaged, for example, by transferring to containers, for example vials or beverage containers. In one example, a portion of the liquid dilution composition is transferred to vials for analysis, eg, evaluation of properties, such as transparency, turbidity, taste, odor, ring formation, crystal formation, and / or other properties.
They are exemplary of the equipment used to dilute the liquid nanoemulsion concentrates to form the liquid dilution compositions containing the diluted concentrates beakers, eg Pyrex® glass beakers, hot plates, eg Thermolyne hot plate, model number 846925 or model number SP46615, stir bars, temperature gauges, for example, temperature probes, for example, Cooper Temperature Probes (Model No. DPP400W) and Balances, for example, the 2.0 kg OHuAs Balance (Model No. CS2000) and / or the Sartorius Analytical Scale (Model BA 110S).
1. Dilutions
Typically, the concentrates provided can be diluted in an aqueous medium to form aqueous liquid dilution compositions over a wide range of dilutions. In one example, the concentrate can be diluted so that the aqueous liquid dilution composition contains between 0.05 g or about 0.05 g and 10 g or about 10 g, typically between 0.05 g and 5 g of the liquid concentrate per 8 fluid ounces. of the liquid (0.236588 liters), at least 8 fluid ounces (0.236588 liters) of the liquid or less than 8 fluid ounces (0.236588 liters)

2. Analysis of Aqueous Liquid Dilution Compositions Containing Liquid Concentrates
The properties of the aqueous liquid dilution compositions containing the liquid concentrates can be evaluated using a number of different evaluation means. For example, transparency can be assessed; desirability for human consumption, eg, pleasant taste and / or odor, eg, no fishy taste / odor, no ring formation, and no crystal formation; stability, for example, absence of oxidation, ring formation, precipitation and / or overcoming of visible phases, with time; and safety for human consumption. Several of these properties can be empirically evaluated, for example, by observing liquids immediately or over time, or by smelling and / or tasting liquids. In one example, after evaluation of the aqueous dilution liquid compositions, the concentrates are reformulated to fit one or more parameters. In another example, the dilution factor can be adjusted.
to. Transparency / turbidity
The transparency of aqueous liquid dilution compositions can be evaluated using one or more of several approaches or for example, empirical observation, particle size measurement, and / or measurement of a haze value. Measurement can be qualitative or quantitative. In one example, a particular quantitative or qualitative transparency value is specified. In another example, the transparency of one liquid can be expressed relative to the transparency of another liquid, for example, an aqueous dilution liquid composition prepared according to the methods provided, or a beverage, for example, a beverage that does not contain the liquid concentrate. In this example, the liquid can be as clear as, less clear, or more clear than another liquid. For example, an aqueous liquid dilution composition containing the liquid concentrate diluted in a beverage may be as clear or about as clear as the same beverage that does not contain the concentrate. Any type of evaluation can be carried out qualitatively, for example by empirical evaluation or quantitatively, for example by taking a measurement of particle size or turbidity.
i. Empirical evaluation
In one example, the transparency / haze of the aqueous liquid dilution composition is qualitatively evaluated, eg, by observation. In one example, a liquid is considered transparent if it does not have an opaque appearance and / or if it contains no or few particles that are visible to the naked eye. In another example, the liquid can be considered relatively clear or relatively cloudy based on a comparison with other liquids, eg, water, fruit juice, soda and / or milk and / or other aqueous dilution liquid composition (s).
ES 2 396 946 T3 prepared according to the methods provided. For example, the aqueous liquid dilution composition can be as clear or about as clear as water or another liquid, eg, a beverage. For example, the liquid that contains the liquid concentrate diluted in a beverage may be as clear or about as clear as the beverage that does not contain the liquid concentrate. In a related example, the liquid can be clear or partially clear when there is no substantial difference, for example, there is no observable difference between the aqueous liquid dilution composition containing the concentrate and the aqueous medium that does not contain the concentrate. A clear liquid is not necessarily colorless. For example, a yellow liquid that does not contain or contains (few) visible particles or opacity can be transparent. In another example, the absence of crystal formation or ring formation may be indicative of a clear liquid.
ii. Particle size
In another example, transparency / haze is evaluated by quantitatively measuring particle size and / or number of particles, in the aqueous liquid dilution composition. In this example, transparency can be expressed as a numerical representation of the particle size, or as a comparison of the particle size of another liquid.
Methods for measuring the particle size of liquids are well known. Any method for measuring particle size can be used, provided it is sensitive to particle size in the expected and / or appropriate ranges of the provided aqueous liquid dilution compositions. For example, particle size analysis is commercially available, for example, from Delta Analytical Instruments, Inc., North Huntingdon, PA. In one example, the particle size of the aqueous liquid dilution composition is measured, for example, by Delta Analytical Instruments, Inc., using a light scattering analyzer, for example, a dynamic light scattering analyzer, for example , The Horiba® LB-550 which can measure particle sizes within a range of 0.001 microns to 6 microns and uses an iterative deconvolution / Fourier transform technique to present data and can measure sample concentrations from ppm to 4.0% of solid; the Horiba® LA-920, which is a laser light scattering instrument having a HeNe laser and a tungsten lamp that can determine particle sizes from 0.02 microns to 2000 microns using Mie's Theory; and other analyzers available from Delta Analytical Instruments, Inc.
Alternatively, the particle size can be measured by viewing the liquid under a microscope at magnification, eg, a 640X magnification. The particle size can then be measured by comparison with a measurement standard, for example a ruler, which is also viewed under magnification. In one example, particles of about 25 nm or greater than about 25 nm are visible, while particles less than 25 nm are not visible, for example, at 640X magnification.
iii. Turbidity measurement
In another example, the transparency / turbidity of the liquid is evaluated and / or expressed using a turbidity measurement, eg, Nephelometric Turbidity Units (NTU). In this example, the turbidity is measured optically, to obtain a value that indicates the opacity or turbidity of the liquid, which is related to the number and size of particles suspended in the liquid. The more transparent the liquid, the lower its turbidity value. Turbidity can be measured optically, for example, using a nephelometer, an instrument with a light, and a detector. The nephelometer measures turbidity by detecting scattered light resulting from exposure of the aqueous liquid dilution composition to incident light. The amount of scattered light is correlated with the amount and size of the particulate matter in the liquid and, thus, with the transparency. For example, a beam of light will pass through a sample that has low turbidity with little alteration, creating very little scattered light, resulting in a low turbidity value (NTU) reading. Other methods for measuring turbidity may be used, including commercial services for measuring turbidity, for example, services available from ACZ Laboratories, Inc., Steamboat Springs, CO.
The following examples are included for illustrative purposes only and are not intended to limit the scope of the invention.
E. Examples
Example 1: General Procedure Used to Prepare the Liquid Nanoemulsion Concentrates in Examples 2-4
Tables 2A (i) to 4A, below, set forth ingredients that were used to prepare a plurality of liquid nanoemulsion concentrates, described in greater detail in Examples 2 to 4, according to the methods provided. Each of these nanoemulsion concentrates contained one or more non-polar active ingredients, and contained water as the polar solvent, and a tocopherol polyethylene glycol succinate (TPGS) surfactant (the TPGS surfactant marketed under the name Vitamin E TPGS® from Eastman Chemical Company).
ES 2 396 946 T3
Each of Tables 2A (i) to 4A shows the milligrams (mg) for each serving (serving size is indicated) of each ingredient in the concentrate, the percentage, by weight (of the total concentrate), for each ingredient and the quantity (g) of each ingredient per batch of the indicated batch size (g). It is also indicated in each table, in the phase column, if each ingredient was added to the aqueous phase (water), the oil phase (oil) or was subsequently added to the emulsion that was formed by emulsifying the oil and aqueous phases (emulsion) .
Each of the liquid nanoemulsion concentrates set forth in Examples 2-4 was prepared using an experimental scale process according to the methods provided. Each of the concentrates could alternatively be prepared by scaling up the experimental scale process to prepare concentrates using a large scale manufacturing process of the methods provided, for example, to prepare larger batch sizes of the concentrates in the following Examples.
The experimental scale process to prepare the concentrates in Examples 2-4 was carried out using the following general steps (details are indicated in the specific examples).
To prepare each of the liquid nanoemulsion concentrates set forth in Examples 2-4 below, the indicated amount of each ingredient was weighed using a Toledo Balance (Model GD13x / USA), a Sartorius Basic Analytical Balance (Model BA110S), or a OHAUS Balance (Model CS2000). The selection of the scale (s) depended on the weight of the particular ingredient (s).
To prepare the aqueous phase, the ingredients of the aqueous phase (indicated as aqueous in each table in the phase column) were added in the indicated amounts (g / batch) to the aqueous phase container (a Pyrex® beaker), and were mixed using a conventional mixer (IKA® model No. RE-161S, which is a top mixer (laboratory shaker) compatible with the experimental scale process). While mixing, the aqueous phase ingredients were heated using a heating apparatus. The heating apparatus was a hot plate (a Thermolyne Hot Plate Model No. SP46615, Bamstead International, Dubuque, Iowa). Except where noted, when the aqueous phase included water and an emulsion stabilizer, those ingredients were added sequentially in the following order: 1) water; 2) emulsion stabilizer. The ingredients of the aqueous phase were heated with the hot plate until the temperature reached 60 ° C. The aqueous phase was kept at 60 ° C before combining and emulsifying the aqueous and oil phases. A temperature meter (temperature probe (Model No. DPP400W, Cooper-Atkins)) was used to evaluate (measure) the temperature of the aqueous phase.
The oil phase ingredients (indicated as oil in each table in the phase column) were added to an oil phase container (a Pyrex® beaker), and mixed using a conventional mixer (IKA® model No. RE -16 1S, which is a top mixer (laboratory shaker) compatible with the experimental scale process). In general, unless otherwise indicated, when the oil phase included two or more surfactants, preservative, nonpolar solvent, cosurfactant, nonpolar compound, and emulsion stabilizer, these ingredients were added sequentially, in the following order : 1) surfactant; 2) preservative; 3) non-polar solvent; 4) co-surfactant; 5) nonpolar compound; and 6) emulsion stabilizer. For example, when the oil phase included surfactant, preservative, and nonpolar compound, these ingredients were added in the following order (unless otherwise indicated): 1) surfactant, 2) preservative; 3) nonpolar compound.
As the oil phase ingredients were mixed, they were heated using a heating apparatus. The heating apparatus was a hot plate (Thermolyne Hot Plate Model No. SP46615, Bamstead International, Dubuque, Iowa). The oil phase ingredients were heated until the mixture reached 60 ° C. The oil phase was mixed at that temperature until all ingredients had dissolved, and was kept at 60 ° C before mixing with the aqueous phase. A temperature meter (temperature probe (Model No. DPP400W, Cooper-Atkins)) was used to evaluate (measure) the temperature of the oil phase.
After both phases had reached 60 ° C and the oil phase components had dissolved, the phases were combined and emulsified using the following steps. A reversible homogenizer (Arde Barinco, Inc .; Model CJ-4E) was placed in an aqueous phase vessel and turned on at 850-1200 RPM. The oil phase was then transferred to the water phase container by pouring the oil phase from the oil phase container into the water phase container. Mixing with the homogenizer continued, with the adjustment of the baffle plate in the homogenizer to achieve and maintain an emulsion, for example, by moving the baffle plate further into the forming emulsion and / or out of the forming emulsion.
Homogenization of the forming emulsion continued at between 850 and 1200 rpm, with rapid cooling. Rapid cooling was effected by placing the aqueous phase container (beaker), containing the forming emulsion, in a water bath, to cool the forming emulsion until the liquid temperature reached between 25 ° C and 43 ° C. C (specified specific temperatures; typically takes about 30 to about 60 minutes).
After emulsifying and quenching, additional ingredients were added, as indicated in the individual Examples / Tables. For example, any ingredient that was added later to the
ES 2 396 946 T3 emulsion (instead of to one of the individual phases) is indicated by the word emulsion in the phase column. The emulsion was mixed while adding any additional ingredients, using a conventional mixer (IKA® model No. RE-16 1S). Exemplary of the additional ingredients that were added in the following examples are flavors (D-limonene and lemon oil) and pH adjusters (eg, citric acid). In several examples (where indicated), the pH of the emulsion was measured using a pH and temperature meter (Hanna Instruments, model HI 8314). When necessary, the pH was adjusted with the appropriate amount of a pH adjuster (amount indicated in the tables), for example citric acid or phosphoric acid, until the emulsion reached a pH between 2.6 and 3.2. . Each of the concentrates produced in the following Examples had a pH of between about
2.6 and 3.2.
As a final step, the concentrates were filtered using a 100 micron end product filter, prior to further evaluation, dilution and / or use.

Example 6: Dilution of Liquid Nanoemulsion Concentrates and Evaluation of Liquid Dilution Compositions
For the evaluation of various properties, the selected liquid nanoemulsion concentrates, prepared in the previous Examples, were diluted according to the methods provided, in an aqueous medium to form aqueous liquid dilution compositions. The results are described in detail in Examples 6A-B below.
Example 6A: Dilution and Transparency Evaluation of Dilution Compositions: Turbidity Analysis
The concentrates prepared in Examples 2A (vi), 2A (xii), 2A (iii), 2A (v) and 3A were diluted in the aqueous medium, according to the methods provided to dilute the concentrates. The resulting aqueous liquid dilution compositions were then evaluated for transparency by measuring turbidity using a nephelometer. Dilution parameters and evaluation results are set forth in Table 6A below. For each sample indicated in Table 6A, the Example in which the concentrate was prepared is indicated.
Each of the liquid nanoemulsion concentrates shown in Table 6A was diluted by adding the amount of concentrate indicated in Table 6A to the amount of water (purified according to the methods provided) indicated in Table 6A. Approximate dilution factors are also shown. The concentrates were diluted in an aqueous medium according to the methods provided to dilute the concentrates, using the following steps:
The indicated amount of water was heated in a Pyrex® beaker, by placing the beaker in a Thermolyne hot plate (Model No. 846925), until the water reached 49.8 ° C. The indicated amount of liquid nanoemulsion concentrate (approximately 1 g) was then added to the heated water, and stirred with a stir bar until dispersed. The resulting aqueous liquid dilution composition was added to a screw cap amber glass vial (Alcon) for evaluation. Each of the liquid dilution compositions containing DHA prepared from the concentrates of Examples 2A (iii) and 2A (v) contained 17.5 mg of DHA (in 250 ml and 500 ml of water, respectively). The liquid dilution composition containing DHA prepared from the concentrate of Example 2A (xii) contained 10 mg of DHA and 20 mg of EPA in 250 ml of water. The liquid dilution composition containing DHA prepared from the concentrate of Example 2A (vi) contained
6.5 mg of DHA and 6.5 mg of EPA in 250 ml of water.
The vials containing the liquid dilution compositions were sent to ACZ Laboratories, Inc., Steamboat Springs, CO, for turbidity analysis using a nephelometer. The results are shown in the form of Nephelometric Turbidity Units (NTU) and are listed in Table 6A below. As shown in Table 6A, each of the aqueous liquid compositions containing the dilute concentrates had an NTU value of less than about 300. Several of the compositions had an NTU value of between about 10 and about 12.

Example 7: General Procedure Used to Prepare Liquid Nanoemulsion Concentrates in Examples 8 and 9
Tables 8A (i) through 9C, below, set forth ingredients that were used to prepare the exemplary nanoemulsion liquid concentrates described in Examples 8 and 9 below. Each of these concentrates contained a non-polar active ingredient, a polar solvent, and a surfactant. Each concentrate additionally contained a certified natural preservative GRAS (benzyl alcohol) and was produced, according to this general method, in a batch of 1000 grams (g) or 500 g (batch sizes indicated in the Tables).
Each of Tables 8A (i) to 9C shows the milligrams (mg) per 2 ml serving of each ingredient in the exemplary concentrate, the percentage, by weight (of the total concentrate) for each ingredient, and the amount in grams (g ) of each ingredient per 1000 g batch. As also indicated in each table, in the phase column, it is said whether each ingredient is added to the aqueous phase (aqueous), to the oil phase (oily) or is subsequently added to the emulsion formed after combining the oil phases and aqueous in the emulsifying stage (emulsion).
Each of the liquid nanoemulsion concentrates set forth in Examples 8 and 9 was prepared using an experimental scale process of the methods provided. To prepare larger batch sizes, the experimental scale process was scaled up to prepare any of these exemplary concentrates in Examples 8-9 using a large scale manufacturing process of the methods provided as above.
108
ES 2 396 946 T3 described in this document.
The experimental scale process to prepare the concentrates in Examples 8 and 9 was performed using the following general steps (additional details are provided in the individual examples):
To prepare the concentrates, the indicated amount of each ingredient was weighed using a Toledo Balance (Model GD13x / USA), a Sartorius Basic Analytical Balance (Model BA110S) or an OHAUS Balance (Model CS2000). The selection of a scale or scales depends on the weight of the particular ingredient or ingredients. To generate the aqueous phase, the ingredients of the aqueous phase (indicated by aqueous in each table in the phase column) were added in the indicated amount (g / batch) to an aqueous phase container (a Pyrex® beaker ), and mixed using a reversible homogenizer (Arde Barinco, Inc .; Model CJ-4E), at 30 RPM. During mixing, the aqueous phase ingredients were heated until the ingredients reached the desired temperature of 60 ° C, using a hot plate as a warming device (a Thermolyne Hot Plate Model No. SP46615, Bamstead International, Dubuque, Iowa) . The temperature of the water phase and the mixing rate were maintained until the water and oil phases were combined and emulsified. A temperature meter (temperature probe (Model No. DPP400W, Cooper-Atkins)) was used to evaluate (measure) the temperature of the aqueous phase. The aqueous phase ingredients included a polar solvent (water, glycerin, or propylene glycol) and additional aqueous phase ingredients, where indicated.
The oil phase ingredients (indicated by oil in each table in the phase column) were added to an oil phase container (a Pyrex® beaker) and mixed using a conventional mixer (IKA® model No.RE- 16 1S, which is a top mixer (laboratory mixer) compatible with the experimental scale process). The oil phase ingredients included non-polar active ingredients and other oil ingredients as indicated in the Examples.
As the oil phase ingredients were mixed, they were heated using a hot plate as a warming apparatus (a Thermolyne Hot Plate Model No. SP46615, Bamstead International, Dubuque, Iowa), to a desired temperature of 60 ° C and they were generally mixed at that temperature until the ingredients had dissolved, and were kept at this temperature before mixing with the aqueous phase. A temperature meter (temperature probe (Model No. DPP400W, Cooper-Atkins)) was used to evaluate (measure) the temperature of the oil phase.
After both phases had reached the appropriate temperatures and the oil phase components had dissolved, the phases were combined and emulsified. The emulsion was carried out with a reversible homogenizer (Arde Barinco, Inc .; Model CJ-4E). The reversible homogenizer that was used to mix the aqueous phase ingredients was held at 30 RPM for mixing during the emulsifying step. While mixing with the homogenizer at this speed, the oil phase was transferred to the water phase container by pouring it from the oil phase container into the water phase container. Mixing with the homogenizer continued, with the adjustment of the baffle plate in the homogenate to achieve and maintain an emulsion, for example by moving the baffle plate further into the forming emulsion and / or out of the forming emulsion. During emulsification, the forming emulsion was rapidly cooled by placing the aqueous phase container (beaker) in a water bath, until the temperature of the liquid reached a desired temperature, as indicated in the Examples, between 35 ° C and 43 ° C, (which typically takes between about 30 and about 60 minutes).
In some examples, after emulsification and quenching, additional ingredients were added, as indicated in the individual Examples / Tables. In some examples, citric acid was added after combining and emulsifying the oil and water phases (indicated by emulsion on the phase column), while mixing with the reversible homogenizer (Arde Barinco, Inc .; Model CJ-4E).
As a final step, the concentrates were filtered using a 100 micron end product filter, prior to further evaluation, dilution and / or use.
