BACKGROUND OF THE INVENTION5 Cleaning the skin is an activity that has been done for millennia.
Over time, skin cleansing and related skin cleansing methods involved the use of soap, surfactants, and the like. Today, a predominant form of skin cleansing compositions is the liquid form that is often known as liquid body soap. Liquid soap users enjoy the conveniences offered by these compositions; however experience is not ideal. Skin cleansing compositions have evolved, the problems associated with these compositions have not. Many of the problems associated with current skin cleansing compositions and methods, particularly liquid body soap compositions, have not been addressed and remain an issue for users of these products today.
Perfumes are frequently associated with liquid body soaps. These perfumes perform a number of tasks. Perfumes within a liquid body soap composition cover and / or mask the odor of a liquid body soap composition with a scent that pleases the user. The perfumes in a composition of liquid soap for the body Also indicate the effectiveness of the product to a user. Additionally, perfumes within a liquid body soap composition are supplied in very small amounts to the skin.
While perfumes within a liquid body soap are supplied to the skin, the delivery of these compositions runs poorly. Most of the perfume within the composition denjeBoaAiefu ΐΝηιιςτι 'IEDAD INDUSTRIAL
<img file="MX339063B_D0006.tif" />
The body is rinsed during the user's cleansing, leaving little perfume deposited on the skin to provide a benefit to the user. Furthermore, the benefit to the user of this perfume reservoir is not maximized, since the release of these materials begins immediately after the reservoir, probably while the user is still fresh from the associated cleaning.
Therefore, there is a need to provide a liquid body soap with a longer lasting perfume composition. Specifically, there is a need to provide a liquid body soap with a perfume composition that deposits, more effectively, and is capable of lasting beyond the user's initial cleaning. This invention addresses these needs.

The term "visually distinct," as used in the present description, refers to a region of the multiphase composition for personal care that has an average composition, so defined from another region that it has a different average composition, where the regions are visible to the naked eye. This would not prevent the different regions from being able to comprise two similar phases where one phase could comprise pigments, dyes, particles, and various optional ingredients and therefore a region of a different average composition. A phase generally occupies a space or several spaces with dimensions greater than that of the colloidal or subcolloidal components it comprises. A phase can be furthermore constituted or reconstituted, collected, or separated into a volume phase to observe its properties, for example, by centrifugation, filtration or the like.

Without theoretical limitations, cyclodextrin-fragrance complexes are believed to be released based on a dilution ratio (water: cyclodextrin-fragment complex). Surprisingly, it was found that the dilution ratio required for Ιε fragrance release is high enough to enable the formulation of a stable pure fragrance complex in an aqueous surfactant environment or, in addition to releasing in additional dilution in the shower (for create the surprising effect of changing the fragrance character during the shower) or release later in the day on the skin. The ability to tailor the release for the desired effect is highly dependent on the choice of perfume molecule and the strength of the cyc complex first beginning to use an odextrin formed. The strength of the complex formed requires that with a fragrance molecule that is, highly, bound by complex formation technology that achieves a high level of complex formation and second requires the selection of perfume molecules with a binding nourishing affinity within the cyclodextrin cavity. The binding affinity of fragrance molecules within the cyclodextrin cavity is governed by how well the perfume molecule fits (based on the size, shape, and chemical affinity of the molecule for the interior of the cyclodextrin cavity).

It is contemplated that PRMs having a FDV of less than about 0.69 (L-PRM) can be used in combination with PRMs having a FDV of at least about 0.69 (H-PRM). Such consideration allows the supply of L-PRM before a provoked dilution step, since these materials are less bound to cyclodextrin. Thus, the supply of materials can be controlled within a perfume and a product that depends on the desired characteristics for the supply of perfume. When staged delivery of PRM is desired, the ratio of H-PRM to L-PRM is between about 1: 2 to about 2: 1, alternatively between about 1: 4 and 4: 1.
The ARDON test has been developed as a mechanism to determine if general perfume release uses complex cyclodextrins within a body of liquid body soap. In this way, the presence of PRM with sufficiently high FDV values can be determined without the need to test each individual PRM to determine the presence or without knowing the final formulation of the final product.
Without theoretical limitations, it is believed that the dilution of the product when it contains cyclodextrin and H-PRM results in a significantly higher ARDON value than products either without cyclodextrin or H-PRM within its structure. This mechanism allows product testing to determine delivery mechanisms without the need to know the chemical composition of the product. The present invention uses compositions having an ARDON value of at least about 130%, alternatively, at least about 140%, alternatively, at least about 150%.
Surfactant phase
One of the phases of the personal care composition of the present invention is a surfactant phase. The surfactant phase comprises a structured domain comprising a surfactant and, optionally, a cosurfactant. The structured domain is preferably an opaque structured domain that is preferably a lamellar phase. The lamellar phase can provide shear resistance, adequate performance to suspend particles and droplets, and at the same time provide long-term stability, since it is thermodynamically stable. The sheet phase tends to have a viscosity that minimizes the need to use viscosity modifiers.
In one embodiment, the personal care compositions of the present invention comprise from about 3% to about 20% of
STnS, alternatively, from about 5% to about 15% STnS, alternatively, from about 7% to about 13% STnS, alternatively, from about 5% to about 13% STnS, alternatively, from about 1% to about 13 % of STnS.
STnS having less than 3 moles of ethoxylation were found to offer surprising structural improvements. Figure 1 illustrates these improvements by comparing a composition comprising, ST1S, ST2S, and ST3S. By increasing dilution levels, ST3S initiates the transition from a lamellar structure to a micellar structure that begins at approximately 19% of the surfactant level. As such, dilution beyond this level results in a loss of structure. This loss of structure has, until now, the need for them to be present

higher surfactant concentrations within a package. ST2S compositions can remain well structured up to a pu ^ q ^^^ p ^ n '.
FROM THE INDUSTRIAL REDUCTION of the surfactant within this example, allowing the transition to a more micellar structure at much higher dilution levels. ST1S compositions can remain lamellar at even lower surfactant concentrations.
Although sodium trideceth sulfate has been described and marketed, the use and benefits of sodium trideceth sulfate having lower ethoxylation values is unknown, additional reasoning supported by the general popularity of ST3S within commercially available products, and the lack of commercial availability of lower ethoxylation products. It is this unknown and surprising result that allows for various benefits of the personal care compositions of the present invention, including improved stability, softness, compatibility, and foaming.
Without claiming to be bound by theory, the rationale for better STNS function, where n is below 3, can be illustrated through the use of dynamic dissipative particle simulations (DPD). As for STnS, the surfactant aggregates form curved surfaces based on the shape of the surfactant and the interactions between the molecules, resulting in phase surfactant architectures; and to the degree of phase structure as measured by rheological parameters, such as zero shear viscosity. To measure the amount of curvature of the surfactant, molecular simulations were performed using DPD by breaking surfactant atoms into globules, where one globule typically represents 3-4 heavy atoms. Simulations were performed in a cube cell with an edge length of approximately 25nm. The compositions of the simulation boxes varied in the average amount of ethoxylation (n = 0 to 3) of STnS. The assembly of the
<img file="MX339063B_D0020.tif" />
Surfactants in aggregates with onset from random positions were observed during the course of the simulations. The DPD curvature was calculated J ^ rlo-íEní<sup>1</sup>
MEXICAN INSTITUTE OF PROPERTY Average of multiple independent simulations for the surface-water surface group of the surfactant of all resulting objects in a simulation framework, which includes all bilayers and micelles, and is a relative measure of the average surface deviation colligative of the main surfactant group from the plane. Zero DPD curvature are flat layers with edge defects, which do not form multilamellar vesicles and are therefore not expected to show structured rheology, e.g. eg, high zero shear viscosity. At DPD curvature of approximately 0.07 and above, elongated micellar structures were observed to form. At intermediate DPD curvature, the curved bilayers can form multilamellar vesicles, leading to high zero shear viscosity and stable compositions.
STnS is often combined with SLS to form a surfactant system. In one embodiment, the personal care compositions of the present invention comprise less than about 5% SLS, alternatively less than about 4% SLS, alternatively less than about 3% SLS, alternatively less than about 2% of SLS, alternatively less than about 1% SLS, alternatively between about 0.1% SLS and about 2% SLS, alternatively about 0% SLS. Without intending to be bound by theory, the presence of SLS is believed to increase the hardness of the personal care composition, which at least in part negates the softness and / or efficacy benefits of beneficial agents within the composition. for personal care.

The personal care compositions of fa<sup>D [</sup>pq $ ^ | $ ”inMqjeSsk additionally comprise a cosurfactant. The cosurfactants in the present invention comprise from about 0.1% to 20%, alternatively from about 2% to about 10% of the personal care composition. The cosurfactants of the present invention comprise amphoteric surfactants, zwltterionic surfactants, and mixtures thereof. In one embodiment, the personal care composition comprises at least one amphoteric surfactant. Amphoteric surfactants suitable for use in the present invention include those generally described as secondary and tertiary aliphatic amine derivatives in which the allphatic radical can be straight-chain or branched-chain and in which one of the aliphatic substituents contains from about 8 to about 18 carbon atoms and one contains an anionic group for solubilization in water, e.g. ex. carboxyl, sulfonate, sulfate, phosphate, or phosphonate. Examples of compounds included in this definition are sodium 3-dodecylaminopropionate, sodium 3-dodecylaminopropanesulfonate, sodium lauryl sarcosinate, N-alkylIltaurines, such as that prepared by reaction of dodecylamine with sodium sesionate, according to the teachings of the US patent USA no. 2,658,072, long-chain N-alkyl of aspartic acids, such as those produced according to the teachings of US Pat.

Associative polymer
In one embodiment, the associative polymer is a crosslinked alkali swellable associative polymer, comprising acidic monomers and associative monomers with hydrophobic end groups, whereby the polymer comprises a percent hydrophobic modification and a hydrophobic side chain comprising alkaline functional groups that have a length. Without intending to be limited by theory, it is believed that acidic monomers contribute to the ability of the polymer to swell in water upon neutralization of the acid groups; and associative monomers anchor the polymer in hydrophobic domains of the structured surfactant, e.g. Eg, lamellae, to confer structure to the surfactant compositions and prevent the polymer from collapsing and losing efficacy in the presence of the electrolyte. The crosslinked associative polymer comprises a percent hydrophobic modification, which is the mole percent of monomers expressed as a percent of the total number of all monomers in the polymer backbone, which includes both acidic and other non-acidic monomers . The percent hydrophobic modification of the polymer, hereinafter% HM, can be determined by the ratio of monomers added during synthesis, or by analytical techniques such as proton nuclear magnetic resonance (NMR). The length of the alkyl side chain can be similarly determined. Monomers

For the purposes of the present invention, all side chains having more than 2 carbons are associative. Associative alkyl side chains comprise, for example, butyl, propyl, stearyl, esteareth, cetyl, lauryl, lauret, octyl, behenyl, beheneth, esteareth, or other linear or branched, saturated or unsaturated alkyl or alketh hydrocarbon side chains.
Crosslinked associative polymers having the preferred% HM and preferred carbon numbers of the hydrophobic end groups of the alkyl side chains were found to provide a significant improvement in structure to the structured surfactant compositions of the present invention, especially the compositions inventives involving reduced levels of surfactant; and supply such a structure at surprisingly low levels of the structuring polymer. Associative polymer concentrations of up to 5% or even 10% are taught in the art to obtain a sufficient amount of the structure, for example, the Illustrative compositions of US Pat. USA 7,119,059 (Llbrlzzl, et al.) And 6,897,253 (Schmucker-Castner, et al.). The Inventors found that when the% HM of the associative polymer and the number of carbons of the alkyl side chain is optimized, the aqueous phase structure of the structured surfactant is increased by the use of only less than 3% by weight of the associative polymer as a percent of the aqueous phase of the structured surfactant, preferably less than 2%, more preferably less than 1%, and even only about 0.2% of the phase, as demonstrated by the inventive examples hereinafter.
The acidic monomer can comprise any acidic functional group, for example, sulfate, sulfonate, carboxylate, phosphonate, or phosphate or mixtures of acid groups. In one embodiment, the acidic monomer co i ivi ri alternatively, the acidic monomer is an acrylate, which ac® *<sup>7</sup> INDUSTRIAL
methacrylic acid. The acidic monomer comprises a polymerizable structure, for example, vinyl functionality. Mixtures of the acidic monomers, for example, mixtures of the acrylic acid and methacrylic acid monomers, are useful.
The associative monomer comprises a hydrophobic end group and a polymerizable component, e.g. eg vinyl, which are bonded. The hydrophobic end group can be attached to the polymerizable component, hence to the polymer chain, by different means but is preferably attached by an ether or ester or amide functionality, such as an alkyl acrylate monomer or a vinyl alkanoate. The hydrophobic end group can be further separated from the chain, for example, by an alkoxy ligand such as an alkyl ether. In one embodiment, the associative monomer is an alkyl ester, alternatively an alkyl (meth) acrylate, where (meth) acrylate is understood to mean either methyl acrylate or acrylate or mixtures of the two.
In one embodiment, the hydrophobic end group of the associative polymer is incompatible with the composition of the aqueous phase and is associated with the foaming surfactant hydrophobic components of the present invention. Without intending to be bound by theory, it is believed that the longer alkyl chains of the end groups of the structuring hydrophobic polymer increase the incompatibility with the aqueous phase to improve structure, while the somewhat shorter alkyl chains having numbers of carbon very similar to hydrophobic foaming surfactant (eg, 12 to 14 carbons) or multiples of it (by bilayers, eg. eg) they are also effective, making a variety of preferred materials that balance these opposing requirements ideally, limited by the solubility of the total molecule itself.

Preferred associative polymers comprise approximately C16 (cetyl) alkyl hydrophobic side chains with approximately 0.7% hydrophobic modification, but the percent hydrophobic modification may be up to the limit of aqueous solubility in the surfactant compositions, e.g. eg, up to 2% or 5% or 10%. An illustrative preferred associative polymer is Aqupec SER-300 manufactured by Sumitomo Seika of Japan, which is the Acrylates / C10-30 alkyl acrylate crosslinked polymer and comprises stearyl side chains with less than about 1% HM. Other preferred associative polymers include stearyl, octyl, decyl, and lauryl side chains. Preferred associative polymers are Aqupec SER-150 (Acrylates / C10-30 alkyl acrylate crosslinked polymer) comprising approximately C18 (stearyl) side chains and approximately 0.4% HM, and Aqupec HV-701EDR comprising about C8 (octyl) and about 3.5% HM. Another preferred polymer is Stabylen 30 manufactured by Sigma 3V SpA, which has branched isodecanoate hydrophobic associative side chains. Importantly, the inventors discovered that not all crosslinked associative polymers are effective, many are detrimental to the structure. Associative polymers having hydrophobic side chains with less than 7 carbons and having a% HM greater than about 25% or about 50% are not preferred. For example, Carbopol
Aqua SF-1 (crosslinked acrylate copolymer) having alkyl side chains with an average "mi" of 4.5 carbons and more than 50% HM is deleterious in the examples below.

Determination of the degree of retention of BCD-PRM complex in a pure liquid body soap product
The BCD-PRM complex was prepared where the degree of complex formation is greater than 90%.
Control product: Liquid body soap with a free fragrance
Test Product: The same liquid body soap with a total equivalent of fragrance coming entirely from a BCD-PRM complex
The degree of complex retention is determined by the average ratio of the void concentration of all PRMs prior to the test product to the control product.
If the ratio is one, the degree of complex retention is zero since all PRMs are released from the BCD and the liquid body soap test product behaves the same as the control product.
If the ratio is zero, the degree of complex retention is one since all the PRMs bind to the BCD, there are no PRMs released from the product.
Gas chromatography / mass spectrometry ("GC-MS") solid phase microextraction (SPME) is used to measure the amount of perfume raw material in the empty space of the products. 1.0 grams of the control and test product was placed in clean 20 ml empty space flasks and allowed to equilibrate for at least 2 hours at room temperature.
The samples are then analyzed using the MPS2-SMPE-GC-MS analysis system (GC-02001-0153, MSD-02001-0154, MPS2-02001-0155).

Instruments AR2000, in order to determine the zero shear viscosity. The determination is made at 25 ° C with the parallel plate measurement system 4 cm in diameter and with a space of 1 mm. The geometry has a shear stress factor of 79580 m-3 to convert the torque obtained into effort. Toothed plates can be used to obtain consistent results when an error occurs.
First the material is placed on the rheometer base plate, the measurement geometry (top plate) is moved at the position 1.1 mm above the base plate. Surplus material is removed at the edge of the geometry by scraping after freezing the geometry. The geometry is then moved to the target position 1mm above the base plate and a pause of approximately 2 minutes is allowed to allow the load stresses to relax. This loading procedure ensures that no tangential stress is loaded at the beginning of the measurement, which could influence the results obtained. If the material contains particles discernible with the naked eye or by touch (globules, e.g. eg) that are larger than about 150 microns in numerical average diameter, the gap established between the base plate and the top plate is increased to the smallest of 4 mm or eight times the diameter of the particle diameter at the 95th percentile of the volume. If the phase does not contain particles larger than 5 mm in some dimension, the particles are removed before measurement.
The measurement is made by applying a continuous increase in shear stress from 0.1 Pa to 1,000 Pa during a time interval of 4 minutes per

decade of increased effort. If the measurement result is eeompotor, for example, yes. it is observed that the material flows from the space, the obtained results are evaluated with the incomplete data points excluded. If there are insufficient points to obtain an exact measurement, the measurement is repeated with a greater number of sample points.
Young's modulus (Pa) is obtained by graphing the stress (Pa) compared to the stress (without units) and by obtaining the slope of the regression line of the initial linear region between stress vs. stress, which typically occurs in the region below about 4% of stress. If the relationship is not linear, the slope of the linear regression line below 2% of the stress is taken as Young's Modulus (Pa), using the unitless stress.
Zero shear viscosity is obtained by taking a first average value of the viscosity in Pascal per seconds (Pa-sec) for the viscosity data obtained between and including 0.1 Pa and the point where the viscosity begins to decline abruptly. After taking the first average viscosity, all viscosity values greater than 5 times the first average value and less than 0.2x the average value are excluded and a second average viscosity value is obtained from the same viscosity data, and excluded the indicated data points. The second average viscosity obtained is the zero cut viscosity.

Ultracentrifuation method
The ultracentrlfugation method is a physical method that is used to determine the structure in a composition or a subset of a composition. The method is also used to determine the rate at which a structured surfactant composition dissolves with dilution to present effective amounts of surfactant to the cleaning environment near surfaces.
A composition is ultracentrifugally separated into separate, but distinguishable, layers. The multiphase personal care composition of the present invention can have multiple distinguishable layers (eg, a structured surfactant layer, and a beneficial layer).
First, approximately 4 grams of the composition is dispensed into a Beckman centrifuge tube (11x60mm) to fill the tube. The composition is then diluted to a dilution level of 10% by using 90% of the composition and 10% DI water by using a suitable mixer and the same amount of composition is supplied in a tube company centrifuge. The dilution of the composition is continued and the tubes are filled in the same manner until a dilution level of 60% is obtained for the composition by using% of the composition with 60% DI water. The tuíjsj ^^ pfrju an ultracentrifuge (Beckman model L8-M or equivalent) pdF is placed<sup>s</sup>fí§ ^ iOiéíYour sling rotor and ultracentrifuge by using the following conditions:
• - -t m. i *<sup>1</sup> "me
50,000 rpm, 2 hours and 40 ° C.
The relative phase volumes of the phases of the composition are measured by measuring the height of each layer using an electronic digital caliper (within 0.01 mm). Those with experience in the field identify the layers using physical observation techniques paired with chemical identification if necessary. For example, the structured surfactant layer is identified by transmission electron microscope (TEM), polarized light microscopy, and / or X-ray diffraction for the present invention as a structured lamellar phase comprising multilamellar vesicles, and the layer Hydrophobic benefit is identified by its low moisture content (less than 10% water measured by Karl Fischer titration). Total height H<sub>to</sub> all materials in the ultracentrifuge tube are measured and included. The height of each layer is then measured from the bottom of the centrifuge tube to the top of the layer, and the span of each layer is determined algebraically by subtraction. The beneficial layer can comprise multiple layers if the beneficial phase has more than one component that can cause the phase to divide into the liquid and waxy layers, or if there is more than one beneficial component. If the charitable phase is divided, the sum of the charitable layers measured is the height of the charitable layer, H<sub>b</sub>Generally, a hydrophobic beneficial layer, when present, is on top of the centrifuge tube.
The surfactant phase can comprise several layers or a single layer, H<sub>c</sub>. In addition, there may be a clear, unstructured, isotropic micellar layer at or near the bottom of the ultracentrifuge tube. Layers immediately

INDUSTRIAL PROPERTY structured layers are often opaque to the naked eye, or translucent, or clear.
There may be several structured layers present, in which case H<sub>c</sub> it is the sum of the individual structured layers. If any type of polymer-surfactant phase is present, it is considered a structured phase and is included in the measurement of H<sub>c</sub>. The sum of the aqueous phases is H<sub>s</sub>.
Finally, the volume ratio of the structured domain is calculated as follows:
Structured domain volume ratio = H<sub>c</sub> / H<sub>s</sub> *100 %
If no beneficial phase is present, the total height is used as the surfactant layer height, H<sub>s</sub>= H<sub>to</sub>. For the present invention, the volume ratio of the structured domain is% of the lamellar phase. Measurement is made for each prepared and centrifuged dilution, i.e. the volume ratio of the structured domain is determined for the composition, and for the 90%, 80%, 70% and 60% dilutions prepared as indicated above.
The highest amount of dilution (i.e. the lowest dilution level) where the composition maintains at least 95% lamellar phase is an indicator of the amount of structure for compositions that have different values of n for
STnS.
In one embodiment, the higher dilution where the composition has at least 95% lamellar phase is greater than about 15%, alternatively, greater than about 25%, alternatively, greater than about

In one embodiment, the composition has a structured ratio of at least about 40%, alternatively, at least about 45%, alternatively, at least about 50%, alternatively, at least about 55%, alternatively, at least about 60%, alternatively , at least about 65%, alternatively, at least about 75%, alternatively, at least about 80%, alternatively, greater than about 90% by volume of the aqueous surfactant composition.
Ultracentrlfuqaclón dilution method
The dilution ultracentrifugation method is a physical method used to determine the amount of structure in a composition at a certain point in its dilution profile, which refers to the composition's ability to foam. The dilution ultracentrifugation method uses the results of the ultracentrifugation method at the 50% dilution point. When consumers use the surfactant compositions with an instrument such as a towel or a bean bag, typically, about 10 ml of the composition is dispensed into the instrument containing about 10 ml of water in it. Consumers shake to foam, requiring the composition to dissolve rapidly at this dilution force. The ability of the structured surfactant compositions to dissolve in the 50% dilution is measured by the method.
The method is identical in all its details to the ultracentrifugation method. The result in the 50% dilution is obtained for a composition and is expressed as the volume of the lamellar phase diluted to 50%.
The results of the dilution ultracentrifugation method are compared with the results obtained for the dissolution rate test for the compositions of the present invention comprising STnS, and
FROM THE INDUSTRIAL PROPERTY the high structure and the reduced foam, and vice versa, which give rise to the improved stability and the aesthetics of use within a narrower range of values of STnS. The STOS composition of Example 4 which is relatively unstructured, has a lower structure after dilution, but is not suitable for the purposes of a structured surfactant composition due to its inability to supply the required stabilization to a composition based on its rheology. The ST3S composition of Example 1 has sufficient structure and rapidly dilutes micellar surfactants useful for foaming and cleansers, but disadvantageously these ST3S compositions cannot be easily formulated into compositions comprising reduced levels of surfactant; they will always be expensive, inefficient, less environmentally preferred, and less gentle. The ST1S composition of Example 3 has a 50% dilute lamellar phase volume of 100%, which will result in poor foam and cleaning characteristics in many modes of use. The ST2S composition of Example 2 demonstrates versatility since at a high degree of structure it still dilutes sufficiently to provide a good foaming result, lather capacity supported by its volume value of lamellar phase diluted to 50% of 70% . ST2S compositions can be prepared at reduced surfactant levels, for example 15%, or 12%, or 10% or 8%, or even 6% surfactant and retain many of the preferred characteristics of the present invention.
In an embodiment of the present invention, the volume of the lamellar phase diluted to 50% for a composition of the present invention is less than about 90%, alternatively, less than about 80%, alternatively, less than 75%.

MEXICAN INSTITUTE
Structured compositions are prone to loss.<sup>i</sup>fetus, '<sup>4</sup>As a result, poor foaming and cleaning characteristics can result. The slow dissolution of structured surfactant phases is largely behind the development of the “Puff” instrument many years ago, a stirring instrument that supports dissolution, foaming and cleaning. Foaming and cleaning result from the ability of aqueous surfactant molecules to diffuse and stabilize air interfaces and soil surfaces. When surfactants remain enclosed in lamellar structures or other organized structures, they are not able to diffuse into the aqueous phase and therefore must first be dissolved as individual monomers and surfactant micelles in order to be effective. Dilution and agitation support dissolution during use. The dissolution rate method measures the extent of dissolution of a surfactant composition in water.

Third phase method to determine the stability of the structured surfactant
The "third phase" method is used to determine the stability of the structured surfactant phase in a personal cleansing composition. The method involves putting the personal care compositions at 50 ° C for 10 days for rapid aging. After rapid aging, approximately 4 grams of the composition is transferred to a Beckman centrifuge tube (11x60mm). The centrifuge tube is placed in a Beckman LE-80 Ultracentrifuge and operated under the following conditions: 50,000 rpm; 2 hours, and at 40 ° C.
After ultracentrifugation, the volume of the third phase is determined by measuring the height of the various surfactant phases with an electronic digital caliper (within 0.01 mm).
The top layer is the hydrophobic beneficial phase layer (hydrocarbons or soybean oil, etc.). The layers below the hydrophobic beneficial phase layers containing surfactant / water are determined as follows: H<sub>to </sub>is the height of all layers containing surfactant / water and H<sub>b</sub> is the height of the clear “third phase” layer just below the hydrophobic beneficial phase layer. It is important to record the readings within 30 minutes after the ultracentrifugation has finished to reduce the migration of the material through the different layers. The volume of the third phase is calculated as follows:% of the volume of the third phase = Hu / H<sub>to</sub> *100 %
Preferably, the structured surfactant composition comprises less than 10% of the "third phase" volume after the rapid aging stability protocol. More preferably, the
INSTITUTO Ml'TCANO OE LA TRCriIC.O structured comprises less than 5% of the volume of the "third IS ^ 'tlespbes ^ Jel rapid aging stability protocol. With — mayen — preference,<sup>1</sup> the structured surfactant composition comprises less than 2% of the "third phase" volume after the rapid aging stability protocol. Still more preferably, the structured surfactant composition comprises less than 1% of the "third phase" volume after the rapid aging protocol. Most preferably, the structured surfactant composition comprises approximately 0% by volume of the "third phase" after the rapid aging protocol.
