DESCRIPTION

Methods to improve the performance of long-lasting cosmetic products.

Technical field

The invention relates to compositions and a method for using said compositions to improve the performance of long-lasting cosmetic products. These compositions, and methods for using such compositions, allow the user to significantly increase the attributes of long-lasting cosmetic products without compromising their primary benefits. Background of the technique

Compositions used to enhance cosmetic products are known in the art. Such compositions include those that are applied over foundation-top compositions, such as lipstick, to provide attributes such as shine, lubrication, and transfer resistance of the cosmetic product to which they are applied. These improved products utilize a variety of polymeric fluids and film-forming technologies. For example, acrylic film formers, which are incorporated into protective lipstick products, such as CSI-incorporated "Sealed with a Kiss," are supplied in a volatile vehicle, alcohol, which is spread over the surface of the lipstick.

Alternative topcoat products to those described above are described in Japanese Patent Application No. HEI 5 [1993] -221829, published August 31, 1993. Such overcoat products are considered to exhibit a improved durability of the makeup effect, suppression of color transfer, and improved applicability. Such topcoat products comprise 0.2 to 25% silica powder and / or alumina powder, and 75% to 99.8% of a general starch perfluorinated polyether:

R¹-—CF₂CFCF₂OR-_p - (CFCF₂OR-_what -CFO —- R² in which R¹ aR⁵ they are independent fluorine atoms, perfluoroalkyl groups or oxyperfluoroalkyl groups; the value of p, q and r is at least zero; wherein the molecular weight of the perfluorinated polyether is from about 500 to about 10,000, wherein P, Q, and R may be equal, but not zero. The preferred perfluorinated polyether described herein is a commercially available product known as Fomblin HC-04, HC-25 and HC-R, available from Montefluosu, Milaén, Italy.

DE 3837473 describes the use of 3% to 60% by weight of sucrose fatty acid ester, in which the remaining fatty acid has 2 to 6 carbon atoms to increase the adhesion capacity of cosmetic compositions.

DE 4025040 describes an oily composition for external application, comprising (a) a dextrin fatty acid ester, (b) a glycerol fatty acid ester having a melting point greater than 20 ° C, and (c) a cosmetically acceptable oil that is liquid at 20 C.

JP63230618 describes a cosmetic composition comprising a mixture of a certain polyethylene wax and a low viscosity fatty acid tri or diglyceride.

Document EP-A-0519727 describes a cosmetic oleogel suitable for topical application to the surface of the human body, comprising (a) from 5 to 95% by weight of a solvent chosen from certain polyol fatty acid polyesters, (b ) from 5 to 70% by weight of a hydrophobic, cosmetically acceptable polymeric thickener substantially free of crosslinking.

Although such compositions can provide certain advantages, they have been found to often undermine the main advantages of the cosmetic products on which they are applied. For example, cosmetic products compromise their shine or sensory attributes in order to enhance the long-lasting properties provided by the composition that is applied on top of the cosmetic product. Alternatively, cosmetic products must sacrifice long-lasting properties in order to enhance the shine and / or sensory attributes provided by such compositions.

Summary of the invention

The present invention relates to methods for using complementary compositions with cosmetic products that have a solubility parameter less than or equal to 8.5 (calories / cm³)^1/2in order to improve the overall performance associated with the cosmetic product. These complementary compositions comprise oils that have a C log P value greater than or equal to 13.

Additionally, the present invention covers a method for improving the transfer resistant and flexible film-forming cosmetic product, wherein said method comprises the steps of:

to. applying a flexible film-forming and transfer resistant cosmetic product, in which said cosmetic product has a solubility parameter less than or equal to 8.5 (calories / cm³) ^1/2;

b. allowing said cosmetic product to dry; Y

c. apply on said cosmetic product a complementary composition in which said composition has a C log P value greater than or equal to 13.

Background of the invention

It is better that, by supplementing the benefits of a cosmetic product with a complementary composition, the main benefits attributable to the cosmetic product are not compromised. In the context of film-forming cosmetic products, the supplemental compositions should be sufficiently incompatible with the cosmetic film that it does not fall apart when the supplemental composition is applied. By incompatible is meant that the complementary composition

ES 2 180 804 T3 comprises specific components that do not undo the film formed after application of the cosmetic product.

to. Transfer resistant, flexible film-forming cosmetic products

The supplemental compositions of the present application can be used in conjunction with all types of cosmetic products where it is desirable to provide additional attributes. In the case of lip products, such attributes include luster, shine, and lubrication.

Lip cosmetic products are well known in the art, and can encompass a number of different formulations in order to provide both cosmetic and skin care benefits to the skin. A benefit that has often been sought by consumers, particularly in a lip cosmetic product, is that of prolonged or "long-lasting" use.

Long-lasting cosmetic products are considered by some to be those that are resistant to transfer onto or to another object that comes into contact with the cosmetic product; for example, the resistance of the lip composition to being removed from table utensils, such as glasses and napkins. However, other factors that are critical in predicting long life is the ability of the cosmetic product to be flexible and resistant to solvents such as food oils once applied to the skin. Such compositions comprise organosiloxy resins, flowable diorganosiloxy polymers, and a volatile vehicle in which the film formed by applying the cosmetic product is substantially resistant to transfer and is flexible, wherein the cosmetic product has surprisingly long durability. Supplemental compositions that are sufficiently incompatible with the cosmetic product are described herein as useful with such cosmetic products. "Sufficiently incompatible" is described to mean that the application of the supplemental composition does not spoil the film formed by such cosmetic products.

Cosmetic products used in conjunction with the complementary composition of the present invention have solubility parameters less than or equal to about 8.5 (calories / cm³)^1/2 on the Hildebrand scale. In general, the solubility parameter is a function of the cohesive energy of the materials or of the cosmetic product comprising said materials. Cohesive energy is simply an attractive force that depends on the electronegativities of the atoms that make up a molecule, and serves as the basis for properties such as viscosity, adhesion, miscibility, and even boiling point. Some materials, like water, have a high cohesive energy; some, like oil, have low cohesive energy. Highly cohesive ingredients are "polar", while less cohesive ingredients are oily or "non-polar". Hildebrand developed a method to deduce the solubility parameter from the boiling point, molecular weight and specific density of a material: JH Hildebrand, JM Prausnitz and RL Scott, Regular and Related Solutions,

New York, Van Nostrand Reinholdt (1950). This Hildebrand solubility parameter has been published for many cosmetic and pharmaceutical materials in Cosmetic Bench Reference, Carol Stream IL, Allured Publishing (1992) and in AF Barton, Handbook of Solubility Parameters and Other Cohesion Parameters, 2-ed., Boca Raton, CRC Press (1992).

b. Complementary compositions

The complementary composition of the present invention comprises oils, and can take forms ranging from solid to liquid. Regardless of the form of the complementary compositions of the present invention, the C log P value of the composition is equal to or greater than 13, preferably greater than or equal to 17, and most preferably greater than or equal to 20.

The C log P value of the composition determines whether the complementary composition is sufficiently incompatible with the cosmetic product in order to improve the performance of the cosmetic products. The P value is the octanol / water partition coefficient of the oils comprising the complementary composition. The octanol / water partition coefficient is the ratio between the equilibrium concentration of the compositions in octanol and in water. Since the octanol / water partition coefficient values ​​are high, they are most conveniently given in the form of the logarithm to base 10, or log P.

The above log P values ​​are calculated using the "C log P" program available from Daylight CIS. This calculated logarithm of P is based on the Hansch and Leo fragment approximation (see A. Leo, in Comprehensive Medicinal Chemistry, vol. 4, C. Hansch, PG Sammens, JB Taylor and CA Ransden, editors, p-295, Pergamon Press, 1990). The fragment approach is based on the chemical structure of each oil ingredient, and takes into account the numbers and types of atoms, the conductivity of the atoms, and the chemical bond. The C log P values ​​are the most reliable and widely used approximations for this physicochemical property.

The oil component of the supplemental composition is the predominant ingredient of the composition. Typically, the oil content of the supplemental composition is at least about 55%, preferably about 65% and most preferably about 75% by weight of the composition. As such, the C log P value of the aggregate for all non-solid molecular entities that comprise the complementary composition is around that of the oil alone. Complementary compositions of the present invention comprise oils selected from the group consisting of polyols and fatty acid polyesters, triglycerides, fluid synthetic polymers, and mixtures thereof.

Polyesters of fatty acids and polyols

Polyol fatty acid polyesters are fatty acid polyesters derived from any aliphatic or aromatic polyol that has at least 4 free hydroxyl groups, of which at least 80% of these are free hydroxy groups, then they are esterified with one or more fatty acids what

ES 2 180 804 T3 have 8 to 22 carbon atoms.

The polyol from which the polyol fatty acid polyesters are derived are preferably chosen from sugar polyols comprising mono-, di- and polysaccharides. Preferred examples of monosaccharide sugar polyols include:

- Polyols of pentose sugars, such as D-ribose, D-arabinose, D-xylose, D-lixose, D-ribulose and D-xylulose;

- Polyols of hexose sugars, such as D-allose, D-altrose, D-glucose, D-mannose, D-gulose, D-idosa, D-galactose, D-talose, D-fructose, D-sorbose and D -tagatose;

- Heptose sugar polyols, such as D-mannoheptulose and D-pseudoheptulose.

The polyol from which the polyol fatty acid polyesters are derived can also be chosen from disaccharides, such as maltose, lactose, cellobiose, sucrose, trehalose, gentiobiose, melibiose and primrose.

The polyol from which the polyol fatty acid polyesters are derived can also be chosen from trisaccharides, such as gentianose and raffinose.

The polyol from which the polyol fatty acid polyesters are derived can alternatively be chosen from sugar alcohols, such as D-mannitol, D-sorbitol, D-ribitol, D-erythritol, Dlactitol and D-xylitol.

The polyol from which the polyol fatty acid polyesters are derived can alternatively be chosen from sugars, such as methylglucaoside and inositol. The preferred sugar polyol is sucrose. Sucrose polyol fatty acid asters, or SPE, are described in the priority document cited in the specification, and are derived from sucrose and vegetable oil. These have been extensively described in the patent literature, in the context of nondigestible oils, including but not limited to U.S. Patents 3,600,186, issued August 17, 1971, Patent 4,005,195, issued on January 25, 1977, Patent 4,005,196, issued January 25, 1977, all assigned to Procter & Gamble Company.

The fatty acids that are used to form the polyol fatty acid polyesters described in this specification can be individual free fatty acids having 8 to 24, preferably 16 to 22 carbon atoms in the fatty acid molecule. These fatty acids can be saturated or unsaturated, linear or branched.

Fats and oils

The useful fats and oils in the present invention are triacylglycerides or triglycerides formed by an esterification reaction of fatty acids with glycerol. Although the distinction between fats and oils is arbitrary, fats are typically considered solid or plastic at room temperature, while oils are liquid under these same conditions. Fatty acids that are subsequently esterified to form triglyceride fats and oils are most commonly derived from marine, animal and plant sources. For more information regarding triglyceride oils, their sources and processing, see Bailey, "Industrial Oil and Fats Products," Interscience Publications.

At least 90% of the ester substitution in the triglyceride backbone has carbon chain lengths of at least 12. Oils are often hydrogenated to some degree to prevent rancidity. Such triglycerides include oils derived from plants, such as soybean oil, castor bean oil, olive oil, sunflower oil, almond oil, peanut oil, rapeseed acid rich in monounsaturated fatty acids, corn oil. , other similarly related oils, and mixtures thereof.

Synthetic polymeric oils

Synthetic polymeric oils are useful in the present invention. Such synthetic polymeric oils are liquid at room temperature, and include crosslinked glycerin / diethylene glycol / adipate polymers, available as Lexorez 100 from Inolex Chemical Company.

Optional ingredients

There are a large number of other ingredients approved for use in the cosmetic technique, which can be used in compositions of the present invention. Such ingredients are approved for use in cosmetics, and can be found in the reference literature, such as CTFA Cosmetic Ingredient Handbook, Second Edition, The Cosmetic, Toiletries and Fragrance Association, Inc., 1988, 1992. Such materials can be used provided that their inclusion does not significantly spoil the film formed once the cosmetic product has been applied to the skin. Such ingredients include waxes, fragrances, flavor oils, skin care ingredients such as sunscreens, emulsifiers, and the like. Hypoallergenic compositions can be obtained in the present invention, wherein said compositions do not contain fragrances, aroma oils, lanolin, sunscreens, particularly PABA, or other sensitizers and irritants. The additional ingredients that are added should not lower the C Log P values ​​for the composition as a whole below 13. The following is a discussion of a non-exclusive group of such additional ingredients.

Although the supplemental composition is typically transparent, colorants, including pigments and particulate materials, such as talc and mica, can be used to add desirable effects to the cosmetic product. Suitable colorants for use in this specification are all inorganic and organic colors / pigments suitable for use in lip compositions. AND^toThese usually include aluminum, barium or calcium salts or lakes. Lacquers are a pigment that is extended or reduced with a solid diluent, or an organic pigment that is prepared by precipitating a water-soluble colorant on an adsorbent surface, which is usually aluminum hydrate. A lacquer is also formed from the precipitation of an insoluble salt from an acidic or basic dye. Also used herein

ES 2 180 804 T3 descriptive of barium and calcium lakes.

The preferred lacquers of the present invention are Red 3 aluminum lacquer, Red 21 aluminum lacquer, Red 27 aluminum lacquer, Red 28 aluminum lacquer, Red 33 aluminum lacquer, Yellow 5 aluminum lacquer, Yellow 6 aluminum lacquer, Aluminum Lacquer Yellow 10, Aluminum Lacquer Orange 5 and Aluminum Lacquer Blue 1, Barium Lacquer Red 6, and Calcium Lacquer Red 7.

Other colors and pigments can also be included in lip compositions, such as pearls, titanium oxides, Red 6, Red 21, Blue 1, Green 5, Orange 5 colorants, chalk, talc, iron oxides and titanium micas.

Waxes can be used in the present invention, in amounts sufficient to provide a traditional solid form composition. Waxes are defined as low melting point organic mixtures or high molecular weight compounds, solid at room temperature and generally similar in composition to fats and oils, except that they do not contain glycoerides. Some are carbohydrates, others are fatty acid esters with alcohols. The waxes useful in the present invention are selected from the group consisting of animal waxes, vegetable waxes, mineral waxes, various fractions of natural waxes, synthetic waxes, petroleum waxes, ethyloenic polymers, types of hydrocarbons such as Fischer-Tropsch waxes, silicone waxes, and their mixtures, in which the waxes have a melting point between 30 ° C and 100 ° C. Specific waxes useful in the present invention are selected from the group consisting of synoetic waxes, ozokerite, jojoba osters, "Unilins", available from Petrolite Corporation, C22 to C50 fatty alcohols, and mixtures thereof. Synthetic waxes include those described in Warth, Chemistry and Technology of Waxes, part 2, 1956, Reinhold Publishing. The most useful waxes herein have melting points of from about 30 ° C to about 115 ° C, and are selected from C8 to C50 hydrocarbon waxes. Such waxes include long chain ethylene oxide polymers combined with a dihydric alcohol, primarily polyoxyethylene glycol. Such waxes include carbowax, from the company Carbide and Carbon Chemicals. Other synoetic waxes include long chain polymers of ethylene with OH or other grouping that stops the length at the end of the chain. Such waxes include FischerTropsch waxes, as described in the aforementioned text, on pages 465-469, and include Rosswax, available from the Ross company, and PT-060, available from the Astor Wax company. Additional synthetic waxes include the alkylated class of polyvinylpyrrolidones or PVPs, including tricontanil-PVP (available as Gannex WP-660, from ISP company) and PVP / eicosene copolymer (available from ISP company).

Emulsifiers can be used as coupling agents having an affinity for the hydrophilic and hydrophobic phases of the lip compositions of this invention. Emulsifiers are also useful for incorporating polar fluids, such as water, propylene glycol, glycerin, or mixtures thereof. Such emulsifiers include those routinely used in cosmoetics, and are found in the CTFA. Polar fluids, such as water, glycerin, propylene glycol and their mixtures, can also be incorporated without an emulsifier, when amphipholic materials such as polyol fatty acid polyesters are used in the composition.

Active skin care ingredients in both water-soluble and water-insoluble forms can be added to the lip composition. Such ingredients include fat-soluble vitamins, sunscreens, and pharmacoeutically active ingredients. These active ingredients for skin care include glycerin; zinc oxide; chamomile oil; ginko biloba extract; pyroglutamic acid, salts or osesters; sodium hyaluronate; 2-hydroxyoctanoic acid; sulfur; salicholic acid; carboxymethylcysteone; and their mixtures.

Method to improve cosmetic products

The present invention encompasses a method for improving the transfer resistant and flexible film-forming cosmetic product, wherein said method comprises the steps of:

804 T3 18

to. applying to the skin a flexible film-forming and transfer-resistant cosmetic product, wherein said cosmetic product has a solubility parameter less than or equal to 8.5 (calories / cm³)^1/2;

b. allowing said cosmetic product to dry; Y

c. apply on said cosmetic product a complementary composition in which said composition has a C log P value greater than or equal to 13.

The user applies both the cosmetic product and the complementary composition of the present invention from a suitable cosmetic applicator. One such applicator used for fluid products is a liquid brush container, described in British Patent 21198037, issued 09/05/90, assigned to Mitsubishi Pencil Co., Ltd., Japan.

Another such cosmetic dispenser is a one-way twist dispensing device with incremental dosing. Such a twisting dispensing device may include a hollow housing defining a chamber with an open dispensing end and a piston located within the chamber and limited in translational movement within the chamber. The piston preferably has a threaded rod extending therein which engages a threaded opening in an actuator so that advancement of the piston towards the dispensing end occurs when the actuator is rotated. The rotation of the actuator causes the product to be dispensed from the dispensing end. Preferably, the actuator is attached to the dispensing end of the housing, in fluid communication with the chamber, where the product is dispensed through the applicator. The applicator may comprise a sleeve and an applicator portion, wherein the sleeve is attached to the dispensing end of the housing, and the applicator portion has at least one hole located therein. Various versions of applicators can be used, for example a fiber brush or an applicator surface that has eraser on it. The fluff is a mat of thin, short, plastic fibers, substantially perpendicular to the application surface. The bristles of a fiber brush are preferably sharp, and are made of a plastic material. Furthermore, the supplemental composition may be formed of a solid and may be supplied in a more traditional applicator or instrument known in the art.
