Description

[Technical Field]

[0001] This disclosure relates, in a broad sense, to a stable, transparent personal cleansing composition that is substantially free of sulfate-containing surfactants and is formulated with anionic surfactants, amphoteric or amphoteric surfactants, cationic deposition polymers, and low concentrations of inorganic salts. [Background technology]

[0002] Most commercially available cleansing compositions, including shampoo compositions, contain sulfate-based surfactants for their high foam volume generation, good foam stability, and effectiveness in cleansing. However, some consumers may prefer shampoo compositions that are substantially free of sulfate-based surfactants. In addition, users of sulfate-free shampoos prefer high-conditioning shampoos because shampoos with higher conditioning properties cause less stripping to the hair. Conditioning shampoos based on sulfate-based surfactants typically contain cationic conditioning polymers that form coacervates with the sulfate-based surfactants during use. However, the use of non-sulfate surfactants in liquid shampoos can be challenging because it can be difficult to formulate compositions with acceptable foam volume, cleansing properties, conditioning effects, stability, and clarity. [Overview of the project] [Problems that the invention aims to solve]

[0003] One common problem with using certain cationic conditioning polymers in products that are substantially free of sulfate-containing surfactants is that they can lead to instability. In particular, as a result of the interaction between cationic polymers and non-sulfate anionic surfactants, a second hydrophobic phase known as a surfactant-polymer coacervate may form in the composition (not the desired formation during use). This is perceived by consumers as a cloudy product or a product containing a precipitate layer and is undesirable. The presence of coacervate in a cleansing composition can lead to separation during storage and inconsistent performance during use. Therefore, there is a need to formulate a stable shampoo product that contains anionic non-sulfate surfactants, amphoteric surfactants, and cationic polymers, and does not form a coacervate phase in the product, but forms a coacervate when diluted with water during use, such as in shampoo, to provide the desired wetting conditioning effect to the hair. There is also a need to enable the formulation of these product variations without the use of rheological modifiers or thickeners. This need is even more important for low-viscosity products, such as foaming products supplied via mechanical formers such as aerosol devices or pumps. The viscosity of these compositions may be significantly lower than that of typical liquid shampoos.

[0004] Surprisingly, it was found that a stable product exhibiting good applicability and good conditioning properties could be achieved. [Means for solving the problem]

[0005] A personal care composition comprising an anionic surfactant in an amount of about 3% by weight and about 35% by weight, an amphoteric surfactant in an amount of about 3% to about 15% by weight, a cationic polymer in an amount of about 0.01% to about 2% by weight, an inorganic salt in an amount of about 0% to about 1.0% by weight, and an aqueous carrier, wherein the composition is substantially free of sulfate-based surfactants and has a %T value greater than about 80.

[0006] A cleansing composition comprising approximately 5% to 35% by weight of an anionic surfactant selected from amino acid-based surfactants, approximately 0.01% to 2% by weight of a cationic polymer, approximately 0% to 1.0% by weight of an inorganic salt, and an aqueous carrier, wherein the composition substantially contains no sulfate-based surfactants and has a %T value greater than approximately 80. [Modes for carrying out the invention]

[0007] This specification concludes with the "Claims," ​​which specifically point to and clearly assert the present invention, but this disclosure is thought to be better understood from the following description.

[0008] As used herein, the term “fluid” includes liquids and gels.

[0009] When used herein, articles such as "a" and "an" are understood to mean one or more of the claims or the things described herein when used in the claims.

[0010] As used herein, "comprising" means that other steps and other components may be added, provided they do not affect the final result. This term encompasses the terms "consisting of" and "consisting essentially of."

[0011] As used herein, “mixture” means a simple combination of materials and any compound that can be obtained as a result from such combination.

[0012] As used herein, "molecular weight" or "M.Wt." refers to the weight-average molecular weight unless otherwise specified. Molecular weight is measured using gel permeation chromatography ("GPC"), the industry standard method. Molecular weight is expressed in grams per mole.

[0013] As used herein, "cleansing composition" includes products such as shampoos, conditioners, conditioning shampoos, shower gels, liquid hand soaps, facial cleansers, and other surfactant-based liquid compositions.

[0014] As used herein, the terms "include", "includes", and "including" are meant to be non-limiting and are understood to mean "comprise", "comprises", and "comprising", respectively.

[0015] All percentages, parts, and ratios are based on the total weight of the composition of the present invention unless otherwise specified. All such weights, when referring to the components presented, are based on the concentration of the active ingredient and thus do not include carriers or by-products that may be present in commercially available materials.

[0016] Unless otherwise indicated, all component or composition concentrations relate to the active portion of such component or composition, and impurities that may be present in commercially available sources of such component or composition, such as residual solvents or by-products, are excluded.

[0017] All maximum numerical limitations given throughout this specification are to be understood to include all lower numerical limitations as if such lower numerical limitations were expressly recited herein. All minimum numerical limitations given throughout this specification are to include all higher numerical limitations as if such higher numerical limitations were expressly recited herein. All numerical ranges given throughout this specification are to include all narrower numerical ranges within such broader numerical ranges as if such narrower numerical ranges were all expressly recited herein.

[0018] Cleansing composition Typically, inorganic salts (NaCl) are added to sulfated surfactant-based cleansing formulations to increase the viscosity of the product. Surprisingly, it has been found that adding inorganic salts to formulations substantially free of sulfate-containing surfactants in the presence of cationic conditioning polymers, and / or using high inorganic salts containing sulfate-free surfactants, can cause instability of the product due to the formation of gel-like surfactant-polymer complexes known as coacervates in the composition. Maintaining a low inorganic salt (NaCl) concentration (about 0 to about 1% by weight) in the formulation solves the instability problem in sulfate-free formulations containing anionic surfactants and high molecular weight cationic polymers. This can be achieved by avoiding or minimizing the addition of additional inorganic salts to the formulation, and / or using low inorganic salt-containing raw materials. For example, commercially available sulfate-free surfactants such as disodium cocoyl glutamate typically contain high concentrations of inorganic salts, such as 5% or more. Amphoteric surfactants such as betaine or sultaine also typically contain high concentrations of inorganic salts, such as NaCl. Using these high-salt raw materials in sulfate-free surfactant-based cleaning formulations with a total NaCl content exceeding approximately 1% may result in the formation of undesirable coacervates in the product. When the inorganic salt concentration in the surfactant raw materials is reduced, and therefore the total salt content in the composition is less than about 1% or lower, a stable, single-phase, clear product can be formulated. On the other hand, when standard high-inorganic-salt materials are used, the product is turbid, two-phase, and unstable. The turbid, two-phase product is likely the result of a gel-like precipitate formed between the anionic surfactant and the high-molecular-weight cationic polymer, known as a coacervate. The solutions described herein prevent undesirable coacervate formation in the product during storage (before use), but allow for coacervate formation if necessary during use after dilution, providing the desired moist conditioning to the consumer.

[0019] To improve the wetting conditioning and deposition properties of various conditioning active substances, especially those with small droplet diameters (i.e., 2 microns or less), it is important that coacervates form when the cleansing composition is diluted with water, rather than while it is in the bottle during storage. To form coacervates at the correct time (during dilution in use), cleansing compositions containing substantially sulfate-free anionic surfactants, amphoteric surfactants, and cationic polymers should maintain an inorganic salt concentration of less than 1%.

[0020] The cleansing composition is transparent before dilution with water. As used herein, the terms “clear” or “transparent” mean that the composition has a transmittance (%T) of at least about 80% at 600 nm. %T may be about 75% to about 100%, about 80% to about 100%, about 85% to about 100%, about 90% to about 100%, or about 95% to about 100% at 600 nm.

[0021] A. Surfactants The cleansing compositions described herein may contain one or more surfactants in the surfactant system. The one or more surfactants may not substantially contain sulfate surfactants. As can be understood, surfactants provide a cleansing effect on soiled items such as hair, skin, and hair follicles by facilitating the removal of oil and other grime. Surfactants generally facilitate such cleansing due to their amphiphilic nature, which allows the surfactant to decompose and form micelles around the oil and other grime, which can then be rinsed away, thereby removing them from the soiled items. Suitable surfactants for cleansing compositions may contain an anionic moiety that allows the formation of coacervates with cationic polymers. Surfactants can be selected from anionic surfactants, amphoteric surfactants, dipolar surfactants, nonionic surfactants, and combinations thereof.

[0022] Cleansing compositions typically utilize sulfate-based surfactants (such as, but not limited to, sodium lauryl sulfate) for foam generation, stability, clarity, and their effectiveness in cleansing. The cleansing compositions described herein are substantially sulfate-free. As used herein, “substantially sulfate-free” means containing sulfate in amounts of about 0% to about 3% by weight, or about 0% to about 2% by weight, or about 0% to about 1% by weight, or about 0% to about 0.5% by weight, or about 0% to about 0.25% by weight, or about 0% to about 0.1% by weight, or about 0% to about 0.05% by weight, or about 0% to about 0.01% by weight, and / or alternatively, not sulfate. As used herein, “not containing” means 0% by weight.

[0023] Furthermore, the surfactant systems described herein contain about 0% to about 1% by weight of inorganic salts.

[0048] B. Cationic polymers The cleansing composition may contain a cationic polymer that enables the formation of coacervates. As can be understood, the cationic charge of the cationic polymer can interact with the anionic charge of the surfactant to form a coacervate. Suitable cationic polymers may include (a) cationic guar polymers, (b) cationic non-guar-galactomannan polymers, (c) cationic starch polymers, (d) cationic copolymers of acrylamide monomers and cationic monomers, (e) synthetic non-crosslinked cationic polymers that may or may not form lyotropic liquid crystals when combined with a cleansing surfactant, and (f) cationic cellulose polymers. In certain examples, two or more cationic polymers may be included.

[0049] Cationic polymers may be included in the cleansing composition in amounts of about 0.05% to about 3% by weight, about 0.075% to about 2.0% by weight, or about 0.1% to about 1.0% by weight. Cationic polymers may have cationic charge densities of about 0.9 meq / g or more, about 1.2 meq / g or more, and about 1.5 meq / g or more. However, the cationic charge density may be about 7 meq / g or less, or 5 meq / g or less. The charge density can be measured at the pH of the intended use of the cleansing composition (e.g., about pH 3 to about pH 9, or about pH 4 to about pH 8). The average molecular weight of cationic polymers can generally be about 10,000 to about 10,000,000, about 50,000 to about 5,000,000, about 100,000 to about 3,000,000, about 300,000 to about 3,000,000, and about 100,000 to about 2,500,000.

The cationic polymer may be a single type, such as guar hydroxypropyltrimonium chloride, a cationic guar polymer having a weight-average molecular weight of about 2,500,000 g / mol or less, and the cleansing composition may have additional cationic polymers of the same or different types.

[0050] Cationic guar polymer The cationic polymer may also be a cationic guar polymer, which is a cationically substituted galactomannan (guar) gum derivative. A suitable guar gum for guar gum derivatives can be obtained as a naturally occurring material from the guar plant species. As can be understood, the guar molecule itself is a linear mannan in which single galactose units branch at regular intervals on alternately positioned mannose units. The mannose units are linked to each other by β(1-4) glycosidic bonds. The galactose branching occurs by α(1-6) bonds. Cationic derivatives of guar gum can be obtained via a reaction between the hydroxyl group of polygalactomannan and a reactive quaternary ammonium compound. The degree of substitution of cationic groups into the guar structure may be sufficient to provide the required cationic charge density described above.

[0051] Cationic guar polymers can have a weight-average molecular weight ("M.Wt.") of less than approximately 3,000,000 g / mol and a charge density of approximately 0.05 meq / g to approximately 2.5 meq / g.

Cationic guar polymers can have charge densities of approximately 0.2 meq / g to approximately 2.2 meq / g, approximately 0.3 meq / g to approximately 2.0 meq / g, approximately 0.4 meq / g to approximately 1.8 meq / g, and approximately 0.5 meq / g to approximately 1.7 meq / g.

[0052] Cationic guar polymers may have a weight-average molecular weight of less than approximately 1,000,000 g / mol and a charge density of approximately 0.1 meq / g to approximately 2.5 meq / g. Cationic guar polymers may have weight-average molecular weights of less than 900,000 g / mol, approximately 150,000 to approximately 800,000 g / mol, approximately 200,000 to approximately 700,000 g / mol, approximately 300,000 to approximately 700,000 g / mol, approximately 400,000 to approximately 600,000 g / mol, approximately 150,000 to approximately 800,000 g / mol, approximately 200,000 to approximately 700,000 g / mol, approximately 300,000 to approximately 700,000 g / mol, and approximately 400,000 to approximately 600,000 g / mol. Cationic guar polymers have charge densities of approximately 0.2 meq / g to approximately 2.2 meq / g, approximately 0.3 meq / g to approximately 2.0 meq / g, approximately 0.4 meq / g to approximately 1.8 meq / g, and approximately 0.5 meq / g to approximately 1.5 meq / g.

[0053] The cleansing composition may contain cationic guar polymer in amounts of about 0.01% to less than about 0.7% by weight, about 0.04% to about 0.55% by weight, about 0.08% to about 0.5% by weight, about 0.16% to about 0.5% by weight, about 0.2% to about 0.5% by weight, about 0.3% to about 0.5% by weight, and about 0.4% to about 0.5% by weight of the cleansing composition.

[0054] Cationic guar polymers can be formed from quaternary ammonium compounds conforming to general formula II.

[0055] [ka] In the formula, R 3 , R 4 , and R 5 R is a methyl group or an ethyl group, 6 is an epoxyalkyl group of the following general formula III,

[0056] [ka] Or, R 6is either a halohydrin group of general formula IV,

[0058] wherein R 7 is C1-C3 alkylene, X is chlorine or bromine, and Z is an anion such as Cl-, Br-, I-, or HSO4-.

[0059] Suitable cationic guar polymers can conform to the following general formula V,

[0060] [Chemical formula] wherein R 8 is guar gum, and R 4 , R 5 , R 6 , and R 7 are the same as defined above, and Z is a halogen. Suitable cationic guar polymers can conform to formula VI,

[0061] [Chemical formula] wherein R 8 is guar gum.

[0062] Suitable cationic guar polymers also include cationic guar gum derivatives such as guar hydroxypropyltrimonium chloride. Suitable examples of guar hydroxypropyltrimonium chloride include the Jaguar® series from Solvay SA, the Hi-Care series from Rhodia, and N-Hance and AquaCat from Ashland Inc. Jaguar® C-500 has a charge density of 0.8 meq / g and a molecular weight of 500,000 g / mol. Optima has a cationic charge density of approximately 1.25 meq / g and a molecular weight of approximately 500,000 g / mol, Jaguar® C-17 has a cationic charge density of approximately 0.6 meq / g and a molecular weight of approximately 2,200,000 g / mol, Jaguar® and approximately 0.8 meq / g cationic charge density, Hi-Care1000 has a charge density of approximately 0.7 meq / g and a molecular weight of approximately 600,000 g / mol, N-Hance3269 and N-Hance 3270 have a charge density of approximately 0.7 meq / g and a molecular weight of approximately 425,000 g / mol, N-Hance3196 has a charge density of approximately 0.8 meq / g and a molecular weight of approximately 1,100,000 g / mol, AquaCat CG518 has a charge density of approximately 0.9 meq / g and a molecular weight of approximately 50,000 g / mol.

[0063] Cationic non-guargalactomannan polymer The cationic polymer may also be a galactomannan polymer derivative. A suitable galactomannan polymer may have a mannose-to-galactose ratio greater than 2:1 on a monomer-to-monomer basis and may be a cationic galactomannan polymer derivative or an amphoteric galactomannan polymer derivative having a net positive charge. As used herein, the term "cationic galactomannan" refers to a galactomannan polymer to which cationic groups have been added. The term "amphoteric galactomannan" refers to a galactomannan polymer to which cationic and anionic groups have been added such that the polymer has a net positive charge.

[0064] Galactomannan polymers can be found in the endosperm of leguminous plant seeds. Galactomannan polymers are composed of a combination of mannose monomers and galactose monomers. A galactomannan molecule is a linear mannan in which individual galactose units branch at regular intervals on a specific mannose unit. The mannose units are linked to each other by β(1-4) glycosidic bonds. Galactose branching occurs via α(1-6) bonds. The ratio of mannose monomer to galactose monomer varies depending on the plant species and may also be influenced by climate. Non-guar galactomannan polymer derivatives may have a mannose-galactose ratio greater than 2:1 on a monomer-to-monomer basis. Preferred mannose-galactose ratios may also be greater than 3:1 or greater than 4:1. Analysis of the mannose-galactose ratio is well known in the art and is typically based on the measurement of galactose content.

[0065] The gums used in the preparation of non-guar-galactomannan polymer derivatives are obtained from natural substances such as plant seeds or beans. Examples of various non-guar-galactomannan polymers include tara gum (3 parts mannose / 1 part galactose), carob or locust (4 parts mannose / 1 part galactose), and cassia gum (5 parts mannose / 1 part galactose).

[0066] Non-guargalactomannan polymer derivatives may have molecular weights ranging from approximately 1,000 g / mol to approximately 10,000,000 g / mol, and from approximately 5,000 g / mol to approximately 3,000,000 g / mol.

[0067] The cleansing compositions described herein may include a galactomannan polymer derivative having a cationic charge density of about 0.5 meq / g to about 7 meq / g. This galactomannan polymer derivative may have a cationic charge density of about 1 meq / g to about 5 meq / g. The degree of substitution of cationic groups to the galactomannan structure may be sufficient to provide the desired cationic charge density.

[0068] Galactomannan polymer derivatives may also be cationic derivatives of non-guar galactomannan polymers, which are obtained by the reaction of a hydroxyl group of a polygalactomannan polymer with a reactive quaternary ammonium compound. Suitable quaternary ammonium compounds for use in forming cationic galactomannan polymer derivatives include those conforming to the general formulas II to VI defined above.

[0069] The cationic non-guargalactomannan polymer derivative formed from the above reagents may be represented by general formula VII.

[0070] [ka] In the formula, R is gum. The cationic galactomannan derivative can be gum hydroxypropyltrimethylammonium chloride, which can be represented more specifically by general formula VIII.

[0071] [ka]

[0072] The galactomannan polymer derivative may be an amphoteric galactomannan polymer derivative having a net positive charge, which can be obtained when the cationic galactomannan polymer derivative further contains an anionic group.

[0073] Cationic non-guargalactomannan can have a mannose-to-galactose ratio greater than approximately 4:1, a molecular weight of approximately 100,000 g / mol to approximately 500,000 g / mol, a molecular weight of approximately 50,000 g / mol to approximately 400,000 g / mol, a cationic charge density of approximately 1 meq / g to approximately 5 meq / g, and a cationic charge density of approximately 2 meq / g to approximately 4 meq / g.

[0074] The cleansing composition may contain at least about 0.05% by weight of a galactomannan polymer derivative. The cleansing composition may contain about 0.05% to about 2% by weight of a galactomannan polymer derivative.

[0075] Cationic starch polymer A suitable cationic polymer may also be a water-soluble cationic modified starch polymer. As used herein, the term “cationic modified starch” refers to starch to which cationic groups have been added before it is broken down into smaller molecular weights, or to starch to which cationic groups have been added after modification to reach a desired molecular weight. The definition of the term “cationic modified starch” also includes amphoteric modified starch. The term “amphoteric modified starch” refers to a starch hydrolysate to which cationic and anionic groups have been added.

[0076] The cleansing compositions described herein may contain cationic modified starch polymers in an amount ranging from about 0.01% to about 10% by weight, and / or from about 0.05% to about 5% by weight, of the composition.

[0077] The cationic modified starch polymer disclosed in this invention has a bound nitrogen percentage of about 0.5% to about 4%.

[0078] Cationic modified starch polymers can have molecular weights ranging from approximately 850,000 g / mol to approximately 15,000,000 g / mol, and from approximately 900,000 g / mol to approximately 5,000,000 g / mol.

[0079] Cationic modified starch polymers may have charge densities of about 0.2 meq / g to about 5 meq / g and about 0.2 meq / g to about 2 meq / g. Chemical modification to obtain such charge densities may involve adding amino and / or ammonium groups to the starch molecule. Non-limiting examples of such ammonium groups include substituents such as hydroxypropyltrimonium chloride, trimethylhydroxypropylammonium chloride, dimethylstearylhydroxypropylammonium chloride, and dimethyldodecylhydroxypropylammonium chloride. Further details are provided in Solarek, DB, Cationic Starches in Modified Starches: Properties and Uses, Wurzburg, OB, Ed., CRC Press, Inc. (Boca Raton, Fla.), 1986, pp. 113-125, which is incorporated herein by reference. The cationic group may be added to the starch before it is broken down to a smaller molecular weight, or it may be added after such modification.

[0080] Cationically modified starch polymers may have a degree of substitution of cationic groups of about 0.2 to about 2.5. As used herein, the "degree of substitution" of a cationically modified starch polymer is the average number of hydroxyl groups on each glucose anhydride unit derivatized by the substituent. Each glucose anhydride unit has three possible hydroxyl groups available for substitution, and the maximum possible degree of substitution is 3. The degree of substitution is expressed on a molar basis as the number of moles of substituents per mole of glucose anhydride units. The degree of substitution is determined by proton nuclear magnetic resonance spectroscopy, which is well known in the art. 1 This can be determined using the 1H NMR method. 1Examples of 1H NMR methods include those described in "Observation on NMR Spectra of Starches in Dimethyl Sulfoxide, Iodine-Complexing, and Solvating in Water-Dimethyl Sulfoxide," Qin-Ji Peng and Arthur S. Perlin, Carbohydrate Research, 160 (1987), 57-72; and "An Approach to the Structural Analysis of Oligosaccharides by NMR Spectroscopy," J. Howard Bradbury and J. Grant Collins, Carbohydrate Research, 71 (1979), 15-25.

[0081] The starch source before chemical modification can be selected from a variety of sources, such as tubers, legumes, cereals, and grains. For example, starch sources include corn starch, wheat starch, rice starch, waxy corn starch, oat starch, cassava starch, glutinous barley, waxy rice starch, glutenous rice starch, sweet rice starch, amyoca, potato starch, tapioca starch, oat starch, sago starch, sweet rice, or mixtures thereof. Suitable cationic modified starch polymers can be selected from decomposed cationic corn starch, cationic tapioca, cationic potato starch, and mixtures thereof. Cationic modified starch polymers include cationic corn starch and cationic tapioca.

[0082] Starch can undergo one or more additional modifications before or after being broken down into smaller molecular weight molecules. Examples of these modifications include crosslinking, stabilization reactions, phosphorylation reactions, and hydrolysis. Examples of stabilization reactions include alkylation and esterification.

[0083] Cationic modified starch polymers may be included in the cleansing composition in the form of hydrolyzed starch (e.g., acid, enzyme, or alkaline decomposition), oxidized starch (e.g., peroxide, peracid, hypochlorite, alkali, or any other oxidizing agent), physically / mechanically decomposed starch (e.g., by thermomechanical energy input of a processing device), or a combination thereof.

[0084] Starch is readily soluble in water and can form a substantially translucent solution in water. The transmittance of the composition is measured by ultraviolet-visible (UV / VIS) absorbance spectroscopy. This method uses a Gretag Macbeth Colorimeter Color to measure the absorption or transmittance of UV / VIS light from the sample. A light wavelength of 600 nm has been shown to be suitable for characterizing the transparency of the cleansing composition.

[0085] Cationic copolymer of acrylamide monomer and cationic monomer The cleansing composition may contain a cationic copolymer of an acrylamide monomer and a cationic monomer, the copolymer having a charge density of about 1.0 meq / g to about 3.0 meq / g.

[0123] The cationic polymers described herein may also help repair damaged hair, particularly chemically treated hair, by providing a substitute hydrophobic F layer. This microscopically thin F layer helps retain moisture and prevents further damage while providing natural weather resistance. Chemical treatment damages the hair cuticle, causing the protective F layer to peel off. As the F layer peels off, the hair becomes more hydrophilic. It has been found that applying lyotropic liquid crystal to chemically treated hair makes the hair even more hydrophobic, so that it looks and feels like untreated hair. While not bound by any particular theory, it is thought that lyotropic liquid crystal complexes form a hydrophobic layer or film, and this layer or film coats and protects the hair fibers in a similar way to how the natural F layer protects hair. The hydrophobic layer can restore the hair to a healthier state, generally like untreated hair. Lyotropic liquid crystals are formed by combining the synthetic cationic polymers described herein with the anionic cleansing surfactant components of the cleansing compositions described above. The charge density of the synthetic cationic polymers is relatively high. It should be noted that some synthetic polymers with relatively high cationic charge densities do not form lyotropic liquid crystals, mainly due to their unusually linear charge densities. Such synthetic cationic polymers are described in International Publication No. 94 / 06403 and are incorporated by reference. The synthetic polymers described herein can be incorporated into stable cleansing compositions that improve the conditioning performance for damaged hair.

[0124] Cationic synthetic polymers capable of forming lyotropic liquid crystals have cationic charge densities of about 2 meq / gm to about 7 meq / gm, and / or about 3 meq / gm to about 7 meq / gm, and / or about 4 meq / gm to about 7 meq / gm. The cationic charge density is about 6.2 meq / gm. These polymers further have molecular weights of about 1,000 to about 5,000,000, and / or about 10,000 to about 2,000,000, and / or about 100,000 to about 2,000,000.

[0125] Cationic synthetic polymers that provide enhanced conditioning and adhesion properties for beneficial agents but do not necessarily form lyotropic liquid crystals may have cationic charge densities of about 0.7 meq / gm to about 7 meq / gm, and / or about 0.8 meq / gm to about 5 meq / gm, and / or about 1.0 meq / gm to about 3 meq / gm. The polymers also have molecular weights of about 1,000 g / mol to about 5,000,000 g / mol, about 10,000 g / mol to about 2,000,000 g / mol, and about 100,000 g / mol to about 2,000,000 g / mol.

[0128] Techniques for analyzing the formation of complex coacervates are known in the art. For example, microscopic analysis of the composition at any selected dilution stage can be used to determine whether a coacervate phase has formed. Such a coacervate phase may be identified as an additional emulsion phase in the composition. Dyes can be used to help distinguish the coacervate phase from other insoluble phases dispersed in the composition. Further details regarding the use of cationic polymers and coacervates are disclosed in U.S. Patent No. 9,272,164, which is incorporated herein by reference.

When small particles are applied to hair, the volume-average particle size may be in the range of approximately 0.01 μm to approximately 4 μm, approximately 0.01 μm to approximately 2 μm, and approximately 0.01 μm to approximately 0.5 μm.

Suitable insoluble polysiloxanes include polysiloxanes having a molecular weight in the range of about 50,000 to about 500,000 g / mol, such as α,ω-hydroxy-terminated polysiloxanes or α,ω-alkoxy-terminated polysiloxanes. The average molecular weight of the insoluble polysiloxane can be in the range of about 50,000 to about 500,000 g / mol. For example, the average molecular weight of the insoluble polysiloxane may be in the range of approximately 60,000 to approximately 400,000; approximately 75,000 to approximately 300,000; approximately 100,000 to approximately 200,000; or the average molecular weight may be approximately 150,000 g / mol.

[0137] Alternatively, the cleansing composition may be substantially silicone-free. As used herein, substantially silicone-free means about 0 to about 0.2% by weight.

[0138] Organic conditioning materials The conditioning agents of the cleansing compositions described herein may further include at least one organic conditioning material, such as an oil or wax, either alone or in combination with other conditioning agents such as the silicones described above. The organic material may be a nonpolymer, oligomer, or polymer. The organic material may be in the form of an oil or wax and may be added to the cleansing formulation in neat or pre-emulsified form. Preferred examples of organic conditioning materials include: i) hydrocarbon oils, ii) polyolefins, iii) aliphatic esters, iv) fluorinated conditioning compounds, v) aliphatic alcohols, vi) alkyl glucosides and alkyl glucoside derivatives; vii) quaternary ammonium compounds; viiii) polyethylene glycols and polypropylene glycols having a molecular weight of up to about 2,000,000, such as those with CTFA names PEG-200, PEG-400, PEG-600, PEG-1000, PEG-2M, PEG-7M, PEG-14M, PEG-45M, and mixtures thereof.

[0139] emulsifier Various anionic and nonionic emulsifiers can be used in the cleansing compositions of the present invention. Anionic and nonionic emulsifiers can be essentially monomers or polymers. Examples of monomers include, but are not limited to, alkyl ethoxylates, alkyl sulfates, soaps, and fatty acid esters, and their derivatives. Examples of polymers include, but are not limited to, polyacrylates, polyethylene glycols, and block copolymers, and their derivatives. Natural emulsifiers such as lanolin, lecithin, and lignin, and their derivatives, are also non-limiting examples of useful emulsifiers.

[0140] Chelating agents This cleansing composition may also contain a chelating agent. Suitable chelating agents are those described in AE Martell & R M Smith, Critical Stability Constants, Vol. 1, Plenum Press, New York & London (1974) and AE Martell & R D Hancock, Metal Complexes in Aqueous Solution, Plenum Press, New York & London (1996), both of which are incorporated herein by reference. With respect to chelating agents, the term “salts and derivatives thereof” means salts and derivatives that contain the same functional structure (e.g., the same chemical backbone) as the referenced chelating agent and have similar or superior chelating properties. This term includes alkali metals, alkaline earth metals, ammonium, substituted ammonium salts (i.e., monoethanolammonium, diethanolammonium, triethanolammonium) salts, esters of chelating agents having an acidic moiety, and mixtures thereof, in particular all sodium, potassium, or ammonium salts. The term “derivative” also includes “chelating surfactant” compounds, such as the compounds exemplified in U.S. Patent No. 5,284,972, and large molecules containing one or more chelating groups having the same functional structure as the parent chelating agent, such as the polymer EDDS (ethylenediamine disuccinic acid) disclosed in U.S. Patent No. 5,747,440. U.S. Patents No. 5,284,972 and No. 5,747,440 are incorporated herein by reference, respectively. Preferred chelating agents may further include histidine.

[0141] The concentration of the EDDS chelating agent or histidine chelating agent in the cleansing composition may be low. For example, the EDDS chelating agent or histidine chelating agent may be included at about 0.01% by weight. If it exceeds about 10% by weight, formulation and / or human safety concerns may arise. The concentration of the EDDS chelating agent or histidine chelating agent may be at least about 0.01% by weight, at least about 0.05% by weight, at least about 0.1% by weight, at least about 0.25% by weight, at least about 0.5% by weight, at least about 1% by weight, or at least about 2% by weight, based on the weight of the cleansing composition.

[0142] Gel Network The cleansing composition may also contain an aliphatic alcohol gel network. The gel network is formed by adding an aliphatic alcohol and a surfactant in ratios of about 1:1 to about 40:1, about 2:1 to about 20:1, and / or about 3:1 to about 10:1. The formation of the gel network involves heating an aqueous dispersion of the aliphatic alcohol together with the surfactant to a temperature above the melting point of the aliphatic alcohol. During this mixing process, the aliphatic alcohol melts, distributing the surfactant into droplets of the aliphatic alcohol. The surfactant carries water into the aliphatic alcohol along with the surfactant. This transforms the isotropic aliphatic alcohol droplets into liquid crystal phase droplets. When this mixture is cooled to a temperature below the chain melting point, the liquid crystal phase is converted into a solid crystalline gel network. The gel network can provide several advantages to the cleansing composition. For example, the gel network can provide a stabilizing effect to cosmetic creams and hair conditioners. Furthermore, the gel network can provide the benefit of a conditioned texture to hair conditioners and shampoos.

[0143] Aliphatic alcohols may be present in the gel network at concentrations ranging from approximately 0.05% to approximately 14% by weight. For example, aliphatic alcohols may be present in amounts ranging from approximately 1% to approximately 10% by weight, and / or approximately 6% to approximately 8% by weight.

[0144] Suitable aliphatic alcohols include those having about 10 to about 40 carbon atoms, about 12 to about 22 carbon atoms, about 16 to about 22 carbon atoms, and / or about 16 to about 18 carbon atoms. These aliphatic alcohols may be straight-chain or branched-chain alcohols, and may be saturated or unsaturated. Non-limiting examples of aliphatic alcohols include cetyl alcohol, stearyl alcohol, behenyl alcohol, and mixtures thereof. A mixture of cetyl alcohol and stearyl alcohol in a ratio of about 20:80 to about 80:20 is preferred.

[0145] A gel network can be prepared by placing water in a container. The water can then be heated to approximately 74°C. Cetyl alcohol, stearyl alcohol, and a surfactant can then be added to the heated water. After mixing, the resulting mixture can be passed through a heat exchanger and cooled to approximately 35°C. Upon cooling, the aliphatic alcohol and surfactant may crystallize, forming a crystalline gel network. Table 1 shows the components and their respective amounts for an example gel network composition.

[0146] To prepare the gel network premix shown in Table 1, water is heated to approximately 74°C, and the amounts of aliphatic alcohol and gel network surfactant shown in Table 1 are added to it. After mixing, the mixture is passed through a mill and a heat exchanger and cooled to approximately 32°C. As a result of this cooling process, the aliphatic alcohol, gel network surfactant, and water form a crystalline gel network.

[0147] [Table 1] 1 In the case of anionic gel networks, the preferred gel network surfactants mentioned above include surfactants having a net negative charge, particularly sulfonates, carboxylates, and phosphates, as well as mixtures thereof.

[0148] In the case of cationic gel networks, the preferred gel network surfactants mentioned above include surfactants having a net positive charge, including quaternary ammonium surfactants and mixtures thereof.

[0149] In the case of amphoteric or zwitterionic gel networks, the preferred gel network surfactants mentioned above include surfactants having both positive and negative charges at the product's operating pH, particularly betaine, amine oxide, sultaine, amino acids, and mixtures thereof.

[0150] Beneficial agent The cleansing composition may further contain one or more beneficial agents. Exemplary beneficial agents include, but are not limited to, particles, colorants, fragrance microcapsules, gel networks, and other insoluble skin conditioning agents or hair conditioning agents such as skin silicones, and natural oils such as sunflower oil or castor oil. The beneficial agents may be selected from the group consisting of particles; colorants; fragrance microcapsules; gel networks; other insoluble skin conditioning agents or hair conditioning agents such as skin silicones, natural oils such as sunflower oil or castor oil; and mixtures thereof.

[0151] Suspension The cleansing composition may contain a suspending agent in a concentration effective for suspending a water-insoluble substance in a dispersed form within the composition, or in a concentration effective for modifying the viscosity of the composition. Such concentrations range from about 0.1% to about 10% by weight and about 0.3% to about 5.0% by weight of the composition. However, as can be understood, if certain glyceride ester crystals are included, the suspending agent may not be necessary, as the specific glyceride ester crystals may act as a suitable suspending or structural agent.

[0152] Suitable suspending agents include anionic polymers and nonionic polymers. Examples include vinyl polymers, such as cross-linked acrylic polymers having the CTFA name Carbomer; cellulose derivatives and modified cellulose polymers, such as methylcellulose, ethylcellulose, hydroxyethylcellulose, hydroxypropylmethylcellulose, nitrocellulose, sodium cellulose sulfate, sodium carboxymethylcellulose, crystalline cellulose, cellulose powder, polyvinylpyrrolidone, polyvinyl alcohol, guar gum, hydroxypropyl guar gum, xanthan gum, acacia gum, tragacanth, galactan, carob gum, guar gum, karaya gum, carrageenan, pectin, agar, and quince seeds (Cydonia oblonga).

[0153] Other suitable suspending agents include crystalline suspending agents that can be classified as acyl derivatives, long-chain amine oxides, and mixtures thereof. Examples of such suspending agents are described in U.S. Patent No. 4,741,855, incorporated herein by reference. Suitable suspending agents include ethylene glycol esters of fatty acids having 16 to 22 carbon atoms. The suspending agent may be ethylene glycol stearate in both monostearate and distearate forms, but distearate containing less than about 7% monostearate is particularly preferred. Other suitable suspending agents include alkanolamides of fatty acids having about 16 to about 22 carbon atoms, or about 16 to 18 carbon atoms, suitable examples of which include stearate monoethanolamide, stearate diethanolamide, stearate monoisopropanolamide, and stearate monoethanolamide stearate. Other long-chain acyl derivatives include long-chain esters of long-chain fatty acids (e.g., stearyl stearate, cetyl palmitate); long-chain esters of long-chain alkanolamides (e.g., stearamide diethanolamide distearate, stearamide monoethanolamide stearate); and the aforementioned glyceryl esters. Long-chain acyl derivatives, ethylene glycol esters of long-chain carboxylic acids, long-chain amine oxides, and alkanolamides of long-chain carboxylic acids may also be used as suspending agents.

[0154] Other long-chain acyl derivatives suitable for use as suspending agents include N,N-dihydrocarbylamidebenzoic acid and its soluble salts (e.g., Na, K), in particular N,N-di(hydrogenated)C of this classification. 16 , C 18 Examples include taloamide benzoic acid species, which are commercially available from Stepan Company (Northfield, Ill., USA).

[0155] Examples of long-chain amine oxides suitable for use as suspending agents include alkyldimethylamine oxides, such as stearyldimethylamine oxide.

[0156] Other suitable suspending agents include primary amines having a fatty acid alkyl moiety with at least about 16 carbon atoms (examples include palmitamine or stearamine), and secondary amines having two fatty acid alkyl moieties, each having at least about 12 carbon atoms (examples include dipalmitoylamine or di(hydrogenated tallow)amine). Further other suitable suspending agents include di(hydrogenated tallow)phthalamides and crosslinked maleic anhydride-methyl vinyl ether copolymers.

[0157] Viscosity modifier Viscosity modifiers can be used to adjust the rheology of the cleansing composition. Suitable viscosity modifiers include carbomers with the trademark names Carbopol934, Carbopol940, Carbopol950, Carbopol980, and Carbopol981, all available from BFGoodrich Company; acrylate / steareth-20 methacrylate copolymer with the trademark name ACRYSOL22, available from Rohm and Hass; non-oxynyl hydroxyethylcellulose with the trademark name AMERCELL POLYMER HM-1500, available from Amerchol; methylcellulose with the trademark name BENECEL, all supplied by Hercules; hydroxyethylcellulose with the trademark name NATROSOL; hydroxypropylcellulose with the trademark name KLUCEL; cetyl hydroxyethylcellulose with the trademark name POLYSURF67; and ethylene oxide and / or propylene oxide polymers with the trademark names CARBOWAX PEG, POLYOX WASR, and UCON FLUIDS, all supplied by Amerchol. Sodium chloride can also be used as a viscosity modifier. Other suitable rheology modifiers include crosslinked acrylates, crosslinked maleic anhydride comethyl vinyl ether, hydrophobic modified associative polymers, and mixtures thereof.

[0158] The cleansing composition was tested using a Brookfield R / S Plus rheometer at 26.6°C for 2 seconds. -1 When measured, it can have a viscosity of approximately 1 cP to 20,000 cP, or approximately 100 cps to 15,000 cps, or approximately 2,500 cP to 12,000 cP, or approximately 1 cP to 5,000 cP, or approximately 3,500 cP to 8,500 cP. cP stands for centipoise.

[0159] dispersed particles Dispersed particles known in the art may be included in the cleansing composition. When such dispersed particles are included, the particles can be incorporated at concentrations of about 0.025% by weight or more, about 0.05% by weight or more, about 0.1% by weight or more, about 0.25% by weight or more, and about 0.5% by weight or more, based on the weight of the composition. However, the cleansing composition may also contain dispersed particles of about 20% by weight or less, about 10% by weight or less, about 5% by weight or less, about 3% by weight or less, and about 2% by weight or less of the composition.

[0160] As can be understood, the cleansing composition may further contain optional components. For example, it may contain amino acids. Suitable amino acids include, for example, water-soluble vitamins such as vitamins B1, B2, B6, B12, C, pantothenic acid, pantothenyl ethyl ether, panthenol, biotin, and derivatives thereof; water-soluble amino acids such as asparagine, alanine, indole, glutamic acid, and salts thereof; water-insoluble vitamins such as vitamins A, D, E, and derivatives thereof; and water-insoluble amino acids such as tyrosine, tryptamine, and salts thereof.

[0161] It may contain an anti-dandruff agent. As can be understood, coacervate formation facilitates the deposition of the anti-dandruff agent on the scalp.

[0162] The cleansing composition may optionally contain pigment materials such as inorganic, nitroso, monoazo, disazo, carotenoid, triphenylmethane, triarylmethane, xanthene, quinoline, oxazine, azine, anthraquinone, indigoid, thion indigoid, quinacridone, phthalocyanine, plant colors, and natural colors, including water-soluble components such as those with a CI name. The composition may also contain antibacterial agents useful as biocides and anti-dandruff agents for cosmetics, including water-soluble components such as piroctone olamine, water-insoluble components such as 3,4,4'-trichlorocarbanilide (triclosan), triclocarban, and zinc pyrithione.

[0163] The cleansing composition may further contain one or more stabilizers. For example, the shelf life of the cleansing composition can be improved by including one or more preservatives such as ethylene glycol distearate, citric acid, citrate, or katone, as well as sodium benzoate, sodium salicylate, and ethylenediaminetetraacetic acid ("EDTA").

[0164] Foam dispenser The shampoo composition may be stored in an aerosol foam dispenser that may include a container for holding the shampoo composition, and dispensed from there. The container may be made of any suitable material, including materials selected from the group consisting of plastic, metal, alloy, laminate, and combinations thereof. The container may be for single use only. The container may be removable from the aerosol foam dispenser, or it may be integrated with the aerosol foam dispenser, or there may be two or more containers.

[0165] The containment vessel may be made of a material selected from the group consisting of rigid materials, flexible materials, and combinations thereof. The containment vessel may be made of a rigid material if it does not collapse under external pressure when the inside is exposed to an incomplete vacuum.

[0166] Alternatively, the hair composition may be stored in a mechanical foam dispenser and dispensed from there. Not limited examples of suitable pump dispensers are those described in International Publications 2004 / 078903, 2004 / 078901, and 2005 / 078063, which may be supplied by Albea (60 Electric Ave., Thomaston, CT 06787 USA) or Rieke Packaging Systems (500 West Seventh St., Auburn, Indiana 46706).

[0167] The shampoo composition can be stored in a squeeze-type foam dispenser and dispensed from there. An example of a squeeze-type foamer is EZ'R, available from Albea.

[0168] The shampoo composition and / or dispenser may contain or substantially not contain a propellant, such as an aerosol propellant.

[0169] propellant The shampoo compositions described herein may contain a propellant in an amount of about 2% to about 10% by weight, or about 3% to about 8% by weight, or about 4% to about 7% by weight of the shampoo.

[0170] The propellant may contain one or more volatile substances that can carry other components of the shampoo in particulate or droplet form in a gaseous state. The propellant may have a boiling point in the range of about -45°C to about 5°C. The propellant may liquefy when packaged in a conventional aerosol container under pressure. The rapid boiling of the propellant as it exits the aerosol foam dispenser may help atomize other components of the shampoo composition.

[0171] Aerosol propellants that can be used in aerosol compositions include chemically inert hydrocarbons such as propane, n-butane, isobutane, cyclopropane, and mixtures thereof, as well as halogenated hydrocarbons such as dichlorodifluoromethane, 1,1-dichloro-1,1,2,2-tetrofluoroethane, 1-chloro-1,1-difluoro-2,2-trifluoroethane, 1-chloro-1,1-difluoroethylene, 1,1-difluoroethane, dimethyl ether, monochlorodifluoromethane, trans-1,3,3,3-tetrafluoropropene (HFO 1234ze available from Honeywell), and mixtures thereof. The propellant may include hydrocarbons such as isobutane, propane, and butane, which can be used due to their low ozone reactivity and can be used as individual components if their vapor pressure ranges from about 1.17 bar to about 7.45 bar, or about 1.17 bar to about 4.83 bar, and / or about 2.14 bar to about 3.79 bar at 21.1°C. The propellant may also include hydrofluoroolefins (HFOs).

[0172] Compositions using HFO propellants can have a higher foam density (approximately twice as high) compared to hydrocarbon propellants, at the same formula pressure and formula % saturated pressure. This higher density allows for a higher weight-to-weight foam dosage per unit volume of the resulting dispensed foam shampoo. This means consumers can use less foam to achieve similar results to those achieved with lower-density foams.

[0173] Pressure and saturation pressure % will be important to ensure sufficient foam distribution throughout the product's lifespan (from the beginning to the middle to the end of the pressurized vessel). 1,3,3,3-tetrafluoropropene may also enable a remarkably high gloss or shine in the distributed foam.

[0174] Method for producing a cleansing composition The cleansing compositions described herein can be formed in the same way as known cleansing compositions. For example, the manufacturing process of a cleansing composition may include the step of mixing together a surfactant, a cationic polymer, and a liquid carrier to form the cleansing composition.

[0175] Test method A. Transparency evaluation Measurement of transmittance (%T) Techniques for analyzing the formation of composite coacervates are known in the art. One method for evaluating coacervate formation during dilution of transparent or translucent compositions is to measure the percentage (%T) of light transmitted through the diluted sample using a spectrophotometer. Typically, as the measured light transmission percentage (%T) decreases with decreasing dilution, a higher level of coacervate formation occurs. Diluted samples can be prepared in various weight ratios of water to composition, e.g., 2 parts water to 1 part composition (2:1), 7.5 parts water to 1 part composition (7.5:1), 16 parts water to 1 part composition (16:1), or 34 parts water to 1 part composition (34:1), and the %T can be measured for each dilution ratio sample. Examples of possible dilution ratios include 2:1, 3:1, 5:1, 7.5:1, 11:1, 16:1, 24:1, or 34:1. By averaging the %T values ​​of samples across a range of dilution ratios, it is possible to simulate and verify how much coacervate a composition will form on average when a consumer applies the composition to wet hair, lathers it, and then rinses it off. The average %T can be calculated by taking the numerical average of the individual %T measurements for the following dilution ratios: 2:1, 3:1, 5:1, 7.5:1, 11:1, 16:1, 24:1, and 34:1.

[0176] %T can be measured using ultraviolet / visible (UV / VI) spectroscopy, which determines the transmission of UV / VIS light through the sample. A light wavelength of 600 nm has been shown to be suitable for characterizing the degree of light transmittance through a sample. Typically, it is best to follow the specific instructions for the particular spectrophotometer used. Generally, the procedure for measuring transmittance percentage begins by setting the spectrophotometer to 600 nm. Then, a calibration "blank" is performed to calibrate the readout to 100 percent transmittance. Next, a single test sample is placed in a cuvette designed to fit the particular spectrophotometer, and care is taken to ensure that there are no bubbles in the sample before measuring %T with the 600 nm spectrophotometer. Alternatively, multiple samples can be measured simultaneously using a spectrophotometer such as the SpectraMax M-5, available from Molecular Devices. Multiple diluted samples can be prepared in a 96-well plate (VWR catalog number 82006-448) and then transferred to a 96-well visible flat-bottom plate (Greiner part number 655-001), ensuring that the samples are free of air bubbles. The flat-bottom plate was placed in a SpectraMax M-5 available from Molecular Devices, and %T was measured using Software Pro v.5® software.

[0177] B.Lasentec FBRM method The composition does not contain coacervates before dilution. One option for measuring the absence of coacervates is to use the Lasentec FBRM method without dilution. Using the Lasentec focused beam reflection (FBRM) method [Model S400A, available from Mettler Toledo Corp], the size and amount of flocs can be determined by chord length and particle count / second (number per second). Compositions containing only surfactants substantially free of sulfates, optionally amphoteric surfactants, cationic deposition polymers, and low concentrations of inorganic salts do not contain flocs. Compositions with other materials added do not contain flocs with particle sizes different from the particle sizes of the other materials added.

[0178] C. Coacervate volume Coacervate centrifugation The presence of coacervates can be measured by centrifugation of the cleansing composition and gravimetrically by the coacervates. Cleansing compositions containing only sulfate-free surfactants, amphoteric surfactants, cationic deposition polymers, and low concentrations of inorganic salts are centrifuged at 9200 rpm for 20 minutes using a Beckman Couller TJ25 centrifuge. Several time / rpm combinations can be used. The supernatant is then removed, and the remaining settled coacervates are evaluated by gravimetrically. The coacervate percentage (%) is calculated as the weight of settled coacervates as a percentage of the weight of the cleansing composition added to the centrifuge tube, using the following formula. This quantifies the proportion of the cleansing composition that is involved in the coacervate phase. The coacervate percentage (%) for compositions containing sulfate-free surfactants, optionally amphoteric surfactants, cationic deposition polymers, and low concentrations of inorganic salts is 0%.

[0180] D. Determination of foam properties Determination of Kruss DFA100 foam properties Prepare a cleansing composition dilution solution by mixing 1 part by weight of cleansg with 10 parts by weight of water. Dispense the shampoo dilution solution into a Kruss DFA100, which generates foam and measures the foam's properties.

[0181] E. Determination of combability characteristics when wet. Wet Combing Force Method Hairpieces of 4-gram, 8-inch long hair from a general population are used for measurement. Each hairpiece is treated with a cleansing composition for 4 cycles (one foam / rinse cycle per cycle, 0.1 gm of cleansing composition per 1 gm of hair in each foam / rinse cycle, drying between cycles). Four hairpieces are treated with each shampoo. The hair is not dried after the previous treatment cycle. While the hair is wet, it is pulled through half of the fine teeth of two Beautician 3000 combs. The force pulling the hairpiece through the comb is measured by a friction analyzer with a load cell (such as an Instron or MTS tensile meter) and output in grams-force (gf). This pull is repeated a total of 5 times per hairpiece. The average wet combing force is calculated by averaging the force measurements from the 5 pulls on the 4 hairpieces treated with each cleansing composition. The data may be presented as the average wet combing force through one or both of the two combs. [Examples]

[0182] The following examples illustrate various personal care compositions. Each personal care composition is prepared using conventional formulation and mixing techniques.
