Description

Technical Field

[0001] The present invention is directed to combinations of non-ethoxylated surfactants and co-surfactants that achieve product viscosity, maintain a desirable foaming profile, and adhere hair / scalp actives.

Background Art

[0002] Ethoxylated surfactants such as sodium lauryl sulfate are widely used in the beauty industry in personal care products. These surfactants have conventionally been used to achieve a consumer-desired product profile including hand viscosity / product texture, foaming, cleansing, and hair / scalp actives adhesion.

[0003] There is a need to develop alternative formulations of shampoo products that utilize non-ethoxylated surfactants without significant negative consumer compromises to meet the ever-changing demands of customers and retailers of ethoxylated-free surfactants.

[0004] When using combinations of non-ethoxylated surfactants and co-surfactants, problems arise in achieving product viscosity, maintaining a desirable foaming profile, and adhering hair / scalp actives.

Summary of the Invention

Means for Solving the Problems

[0005] The present invention is directed to a personal care composition comprising from about 6% to about 15% sodium lauryl sulfate, in a ratio of sodium lauryl sulfate to co-surfactant of from about 0.63:1 to about 15:1, and from about 10% to about 20% total surfactant, having a viscosity of 3000 cps to 20,000 cps and containing less than about 2% sodium lauryl sulfate.

[0067] The personal care compositions of the present invention may contain a galactomannan polymer derivative having a mannose to galactose ratio greater than 2:1 on a monomer to monomer basis. The galactomannan polymer derivative is selected from the group consisting of a cationic galactomannan polymer derivative and an amphoteric galactomannan polymer derivative having a net positive charge. As used herein, the term "cationic galactomannan" refers to a galactomannan polymer to which a cationic group has been added. The term "amphoteric galactomannan" refers to a galactomannan polymer to which a cationic group and an anionic group have been added such that the polymer has a net positive charge.

[0068] Galactomannan polymers are present in the endosperm of seeds of leguminous plants. Galactomannan polymers are composed of a combination of mannose monomers and galactose monomers. Galactomannan molecules are linear mannans in which single-unit galactose units branch off at regular intervals on specific mannose units. Mannose units are linked to each other by β(1-4) glycosidic bonds. Galactose branching occurs by α(1-6) bonds. The mannose monomer to galactose monomer ratio varies by plant species and is also affected by climate. The non-guar galactomannan polymer derivative of the present invention has a mannose to galactose ratio greater than 2:1 on a monomer-to-monomer basis. A suitable mannose to galactose ratio may be greater than about 3:1, and the mannose to galactose ratio may be greater than about 4:1. Analysis of the mannose to galactose ratio is well known in the art and is typically based on the measurement of galactose content.

[0069] The gums used in the preparation of non-guar galactomannan polymer derivatives are typically obtained as naturally occurring materials such as seeds of plants or legumes. Examples of various non-guar galactomannan polymers include, but are not limited to, tara gum (mannose 3 parts / galactose 1 part), locust bean or carob (mannose 4 parts / galactose 1 part), and cassia gum (mannose 5 parts / galactose 1 part).

[0070] The non-guar galactomannan polymer derivative can have a molecular weight of about 1,000 to about 10,000,000, and / or about 5,000 to about 3,000,000.

[0071] The personal care composition of the present invention can also 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 can have a cationic charge density of about 1 meq / g to about 5 meq / g. The degree of substitution of cationic groups onto the galactomannan structure needs to be sufficient to provide the required cationic charge density.

[0072] The galactomannan polymer derivative may be a cationic derivative of a non-guar galactomannan polymer, which is 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 the formation of the cationic galactomannan polymer derivative include those conforming to general formulas 1 to 5 defined above.

[0073] The cationic non-guar galactomannan polymer derivative formed from the above reagents is represented by general formula 6,

[0076] Alternatively, the galactomannan polymer derivative may be an amphoteric galactomannan polymer derivative having a net positive charge, which is obtained when the cationic galactomannan polymer derivative further contains an anionic group.

[0077] Cationic non-guar galactomannan can have a mannose-to-galactose ratio greater than about 4:1, a molecular weight of about 1,000 g / mol to about 10,000,000 g / mol, and / or about 50,000 g / mol to about 1,000,000 g / mol, and / or about 100,000 g / mol to about 900,000 g / mol, and / or about 150,000 g / mol to about 400,000 g / mol, and a cationic charge density of about 1 meq / g to about 5 meq / g, and / or 2 meq / g to about 4 meq / g, and can be obtained from a plant called cassia.

[0078] Personal care compositions can include a water-soluble cationic modified starch polymer. As used herein, the term "cationic modified starch" refers to starch to which a cationic group has been added before the starch is degraded to a smaller molecular weight, or starch to which a cationic group has been added after modification of the starch to reach a desired molecular weight. The definition of the term "cationic modified starch" includes amphoteric modified starch. The term "amphoteric modified starch" refers to a starch hydrolyzate to which a cationic group and an anionic group have been added.

[0079] The cationic modified starch polymer disclosed herein has a percentage of bound nitrogen of about 0.5% to about 4%.

[0080] The cationic modified starch polymer used in personal care compositions can have a molecular weight of about 850,000 g / mol to about 1,500,000 g / mol, and / or about 900,000 g / mol to about 1,500,000 g / mol.

[0081] The personal care composition can include a cationic modified starch polymer having a charge density of from about 0.2 meq / g to about 5 meq / g and / or from about 0.2 meq / g to about 2 meq / g. Chemical modifications for obtaining such charge density can include, but are not limited to, adding amino groups and / or ammonium groups to the starch molecule. Non-limiting examples of these ammonium groups can include substituents such as hydroxypropyltrimonium chloride, trimethylhydroxypropylammonium chloride, dimethylstearylhydroxypropylammonium chloride, and dimethyldodecylhydroxypropylammonium chloride. See Solarek, D.B., Cationic Starches in Modified Starches: Properties and Uses, Wurzburg, O.B., Ed., CRC Press, Inc., Boca Raton, Fla. 1986, pp 113-125. The cationic groups may be added to the starch before being degraded to a smaller molecular weight, or the cationic groups may be added after such modification.

[0082] The cationic modified starch polymer generally has a degree of substitution of cationic groups of from about 0.2 to about 2.5. As used herein, the "degree of substitution" of a cationic modified starch polymer is the average value of the number of hydroxyl groups on each glucose anhydride unit derivatized by a substituent. Since each glucose anhydride unit has three possible hydroxyl groups available for substitution, the maximum possible degree of substitution is 3. The degree of substitution is expressed on a molar average basis as the number of moles of substituent per mole of glucose anhydride unit. The degree of substitution can be determined using proton nuclear magnetic resonance spectroscopy (".sup.1H NMR") methods well known in the art. Suitable.sup.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.

[0083] The starch source before chemical modification can be selected from various sources such as tubers, legumes, cereal straws, and grains. Non-limiting examples of starches from this source include corn starch, wheat starch, rice starch, waxy corn starch, oat starch, cassava starch, waxy barley, waxy rice starch, glutinous rice starch, sticky rice starch, amoca, potato starch, tapioca starch, oat starch, sago starch, sticky rice, or mixtures thereof.

[0084] The cationically modified starch polymer can be selected from degraded cationic corn starch, cationic tapioca, cationic potato starch, and mixtures thereof. Alternatively, the cationically modified starch polymer is cationic corn starch and cationic tapioca.

[0085] The starch can include one or more additional modifications before being degraded to a smaller molecular weight or after being modified. For example, these modifications can include cross-linking, stabilization reactions, phosphorylation reactions, and hydrolysis. Stabilization reactions can include alkylation and esterification.

[0086] The cationically modified starch polymer can be incorporated into the composition in the form of hydrolyzed starch (e.g., acid, enzyme, or alkaline hydrolysis), oxidized starch (e.g., peroxide, peracid, hypochlorite, alkali, or any other oxidizing agent), physically / mechanically degraded starch (e.g., by input of thermal mechanical energy in a processing device), or a combination thereof.

[0087] The optimal form of the starch is one that readily solubilizes in water and forms a substantially transparent aqueous solution (about 80% transmittance at 600 nm). The transmittance of the composition is measured by ultraviolet-visible (UV / Visible, UV / VIS) absorbance measurement, which measures the absorbance or transmittance of UV / VIS light of the sample using a Gretag Macbeth Colorimeter Color i5 according to the relevant instructions. It has been shown that a light wavelength of 600 nm is suitable for characterizing the transparency of the cosmetic composition.

[0088] Cationic modified starches suitable for use in personal care compositions are available from known starch suppliers. Nonionic modified starches, which can be further derivatized to cationic modified starches known in the art, are also suitable for use in personal care compositions. Other suitable starting materials for modified starches may be quaternized to produce cationic modified starch polymers suitable for use in personal care compositions, as is known in the art.

[0089] Starch decomposition procedure: A starch slurry can be prepared by mixing granular starch in water. The temperature is raised to about 35 °C. Next, an aqueous potassium permanganate solution is added at a concentration of about 50 ppm based on the starch. The pH is raised to about 11.5 with sodium hydroxide, and the slurry is stirred well to prevent the starch from settling. Next, a about 30% solution of hydrogen peroxide diluted with water is added until the peroxide concentration based on the starch reaches about 1%. Subsequently, the pH is returned to about 11.5 by adding additional sodium hydroxide. This reaction is completed over about 1 to about 20 hours. Next, the mixture is neutralized with dilute hydrochloric acid. The decomposed starch is recovered by filtration and then washed and dried.

[0126] The cationic polymers described herein can serve to provide a surrogate hydrophobic F-layer to damaged hair, particularly chemically treated hair. The microscopically thin F-layer provides natural weather resistance while helping to retain moisture and prevent further damage. Chemical treatment damages the hair cuticle and causes the protective F-layer to peel off the hair. As the F-layer peels off, the hair becomes more hydrophilic. It has been found that when a lyotropic liquid crystal is applied to chemically treated hair, the hair becomes more hydrophobic and its appearance and feel become like that of untreated hair. Without being bound by any theory, it is believed that the lyotropic liquid crystal complex forms a hydrophobic layer or film that coats the hair fiber and protects the hair in a manner similar to how the natural F-layer protects the hair. The hydrophobic layer returns the hair to a generally healthier state similar to untreated hair. The lyotropic liquid crystal is formed by combining the synthetic cationic polymers described herein with the anionic detergent surfactant component of the personal care composition above. The charge density of the synthetic cationic polymer is relatively high. It should be noted that some synthetic polymers with a relatively high cationic charge density do not form lyotropic liquid crystals, mainly due to their unusual linear charge density. Such synthetic cationic polymers are described in International Publication No. WO 94 / 06403 (Reich et al.). The synthetic polymers described herein can be incorporated into stable personal care compositions that improve the conditioning performance on damaged hair.

[0150] Suspension wax Suitable stabilizers include mono-esters and / or di-esters of alkylene glycols having the following formula:

[0151] [Chemical formula] In the formula, R1 is a linear or branched C12-C22 alkyl group, R is a linear or branched C2-C4 alkylene group, P is selected from H, C1-C4 alkyl or -COR2, and R2 is C4-C22 alkyl, or in other embodiments, C12-C22 alkyl, n = 1-3.

[0152] In one embodiment, the long-chain fatty ester has the above general structure [wherein R1 is a linear or branched C16-C22 alkyl group, R is -CH2-CH2-, P is selected from H or -COR2, and R2 is C4-C22 alkyl, and in other embodiments, C12-C22 alkyl].

[0153] Typical examples are fatty acids containing about 6 to about 22, about 12 to about 18 carbon atoms, such as caproic acid, caprylic acid 2-ethylhexanoic acid, capric acid, lauric acid, isotridecanoic acid, myristic acid, palmitic acid, palmitoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, petroselinic acid, linoleic acid, linolenic acid, arachidic acid, gadoleic acid, behenic acid, erucic acid, and mixtures thereof, and monoesters and / or diesters with ethylene glycol, propylene glycol, diethylene glycol, dipropylene glycol, triethylene glycol or tetraethylene glycol.

[0154] In one embodiment, ethylene glycol monostearate (EGMS) and / or ethylene glycol distearate (EGDS) and / or polyethylene glycol monostearate (PGMS) and / or polyethylene glycol distearate (PGDS) are the suspension waxes used in the composition. There are several commercial suppliers of these materials. For example, PEG6000MS® is available from Stepan, and Empilan EGDS / A® is available from Albright & Wilson.

[0155] Conventionally, glyceride ester compounds can be used as structuring agents in personal care compositions. For example, Thixcin® R is trihydroxystearin, manufactured by Elementis Specialties (New Jersey), and is a commercially available hydrogenated castor oil that is marketed as a stabilizer and structuring agent for personal care compositions. Suitable glyceride esters for the personal care compositions described herein can be selected from any crystalline glyceride ester that enables the formation of coacervates in personal care compositions containing suitable surfactants and cationic polymers. For example, suitable glyceride esters are hydrogenated castor oils (such as trihydroxystearin or dihydroxystearin).

[0156] Examples of additional crystalline glyceride esters can include substantially pure triglycerides of 12-hydroxystearic acid. 12-Hydroxystearic acid is the pure form of the triglyceride of fully hydrogenated 12-hydroxy-9-cis-octadecenoic acid. As can be appreciated, many additional glyceride esters are possible. For example, variations in the hydrogenation process and natural variations in castor oil can enable the production of additional suitable glyceride esters from castor oil.

[0157] Suitable glyceride esters can also be formed from a mixture of one or more glycerides. For example, a mixture of glycerides containing about 80% by weight or more of castor oil may be suitable. Other suitable mixtures include a mixture of triglycerides only, a mixture of diglycerides and triglycerides, a mixture of triglycerides, diglycerides, and monoglycerides in a limited amount, such as less than about 20% by weight of the mixture, or any mixture thereof containing the corresponding acid hydrolysis products of any of the glycerides up to about 20% by weight of the mixture. About 80% by weight or more of the mixture may be chemically identical to the glyceride of fully hydrogenated ricinoleic acid, i.e., the glyceride of 12-hydroxystearic acid. Hydrogenated castor oil can be modified such that in a given triglyceride, two 12-hydroxystearic moieties and one stearic moiety are present. Alternatively, partial hydrogenation can also be used. However, poly(oxyalkylated) castor oil is not suitable because it has an unsuitable melting point.

[0158] Castor oils include glycerides, particularly triglycerides, containing a C10-C22 alkyl or alkenyl moiety having a hydroxy group. In the hydrogenation of castor oil, hydrogenated castor oil is produced by the conversion of double bonds present as ricinoleyl moieties in the starting oil. These moieties are converted to saturated hydroxyalkyl moieties, such as hydroxystearyl, ricinoleyl moieties. Hydrogenated castor oil (HCO) herein may, in some embodiments, be selected from trihydroxystearic acid, dihydroxystearic acid, and mixtures thereof. HCO can be processed in any suitable starting form including, but not limited to, solids, melts, and mixtures thereof. Useful HCO has the following properties: a melting point of about 40°C to about 100°C, or about 65°C to about 95°C, and / or an iodine value in the range of about 0 to about 5, or about 0 to about 4, or about 0 to about 2.6. The melting point of HCO can be measured using DSC: differential scanning calorimetry.

[0159] Suitable HCOs include those that are commercially available. Non-limiting examples of commercially available HCOs that are suitable for use include THIXCIN-R® (supplied by Elementis), which is supplied as a powder having small particles (99 wt% is less than 44 μm).

[0160] The present invention is not intended to be directed only to the use of hydrogenated castor oil. Any other suitable crystallizable glyceride may be used. In one example, the structuring agent is a substantially pure triglyceride of 12-hydroxystearic acid. This molecule corresponds to the pure form of the triglyceride of fully hydrogenated 12-hydroxy-9-cis-octadecenoic acid. Naturally, the composition of castor oil can vary to some extent. Similarly, the method of hydrogenation can also vary. Any other suitable equivalent substance, such as a mixture of triglycerides in which at least about 80 wt% is derived from castor oil, may be used. Exemplary equivalent substances mainly contain, or consist of, triglycerides; or mainly contain, or consist of, a mixture of diglycerides and triglycerides; or mainly contain, or consist of, a mixture of triglycerides and diglycerides and a limited amount, for example, less than about 20 wt% of monoglycerides of the mixture of said glycerides; any of the foregoing glycerides, and a limited amount, for example, less than about 20 wt% of the corresponding acid hydrolysis products of any of the foregoing glycerides, mainly contain, or consist of.

[0161] The stabilizing premix contains from about 4 wt% to about 30 wt% of 100% active stabilizer in the personal care composition. In other embodiments, the stabilizing premix contains from about 15% to about 25% stabilizer.

[0162] The suspension wax can be from about 0.01% to about 4% in the present invention. The suspension wax can be from about 0.1% to about 3% in the present invention. The suspension wax can be from about 0.5% to about 2% in the present invention. The suspension wax can be from about 0.3% to about 1.5% in the present invention.

For example, the shelf life of the personal care composition can be improved by including one or more of preservatives such as ethylene glycol distearate, citric acid, citrate salts, caton, sodium chloride, sodium benzoate, and ethylenediaminetetraacetic acid ("EDTA").

[0171] Such optional components need to be physically and chemically compatible with the components of the composition and should not unduly impair the stability, aesthetics, or performance of the product. The CTFA Cosmetic Ingredient Handbook, 10th Edition (published by the Cosmetic, Toiletry, and Fragrance Association, Inc. (Washington, D.C.)) (2004) (hereinafter "CTFA") describes various non-limiting substances that can be added to the compositions herein.

[0172] Conditioning agent The conditioning agent of the personal care composition may be a silicone conditioning agent. The silicone conditioning agent may include volatile silicone, non-volatile silicone, or a combination thereof. The concentration of the silicone conditioning agent is typically in the range of about 0.01% to about 10% by weight, about 0.1% to about 8% by weight, about 0.1% to about 5% by weight, and / or about 0.2% to about 3% by weight of the composition. Non-limiting examples of suitable silicone conditioning agents and optional suspending agents for silicone are described in U.S. Reissue Patent No. 34,584, U.S. Patent Nos. 5,104,646, and 5,106,609, the disclosures of which are incorporated herein by reference.

[0173] The silicone conditioning agent for use in the composition of the present invention may have a viscosity of about 20 to about 2,000,000 centistokes ("cSt"), about 1,000 to about 1,800,000 cSt, about 10,000 to about 1,500,000 cSt, and / or about 20,000 to about 1,500,000 cSt when measured at 25°C.

[0174] The dispersed silicone conditioning agent particles typically have a volume average particle size in the range of about 0.01 micrometer to about 60 micrometers.

[0175] Further information on silicones, including silicone fluids, rubbers, and resins, and sections considering the manufacture of silicones, can be found in Encyclopedia of Polymer Science and Engineering, vol. 15, 2d ed., pp 204 - 308, John Wiley & Sons, Inc. (1989), the disclosure of which is incorporated herein by reference.

[0176] Examples of silicone emulsions suitable for use in the present invention include, but are not limited to, emulsions of insoluble polysiloxanes prepared according to the descriptions set forth in U.S. Patent No. 6,316,541 or 4,476,282 or U.S. Patent Application Publication No. 2007 / 0276087. Thus, suitable insoluble polysiloxanes include polysiloxanes such as α,ω-hydroxy-terminated polysiloxanes or α,ω-alkoxy-terminated polysiloxanes having an internal phase viscosity of about 5 cSt to about 500,000 cSt. For example, the insoluble polysiloxane can have an internal phase viscosity of less than 400,000 cSt, less than 200,000 cSt, about 10,000 cSt to about 180,000 cSt. The insoluble polysiloxane can have an average particle size in the range of about 10 nm to about 10 micrometers. The average particle size can be in the range of about 15 nm to about 5 micrometers, about 20 nm to about 1 micrometer, or about 25 nm to about 500 micrometers.

[0177] The average molecular weight of the insoluble polysiloxane, the internal phase viscosity of the insoluble polysiloxane, the viscosity of the silicone emulsion, and the size of the particles containing the insoluble polysiloxane are measured by methods widely used by those skilled in the art, such as the methods disclosed in Smith, A.L. The Analytical Chemistry of Silicones, John Wiley & Sons, Inc.: New York, 1991. For example, the viscosity of the silicone emulsion can be measured at 30 °C using a Brookfield viscometer equipped with spindle 6 at 2.5 rpm. The silicone emulsion may further contain an additional emulsifier together with an anionic surfactant.

[0178] Other classes of silicone suitable for use in the compositions of the present invention include: i) silicone fluids (including but not limited to silicone oils), which are fluid substances having a viscosity of less than about 1,000,000 cSt when measured at 25°C; ii) aminosilicones containing at least one primary, secondary, or tertiary amine; iii) cationic silicones containing at least one quaternary ammonium functional group; iv) silicone rubbers (including materials having a viscosity of 1,000,000 cSt or more when measured at 25°C); v) silicone resins including a crosslinked polymer siloxane system; vi) high refractive index silicones having a refractive index of at least 1.46; and vii) mixtures thereof.

The organic material can be non-polymeric, oligomeric, or polymeric. It may be in the form of an oil or wax and may be added directly to the formulation or in a pre-emulsified form. Some non-limiting 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; viii) 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, but are not limited thereto.

[0180] gel network In the present invention, a gel network may be present. The gel network components of the present invention include at least one type of aliphatic amphiphilic substance. As used herein, "aliphatic amphiphilic substance" refers to a hydrophobic terminal group defined as an alkyl, alkenyl (including up to three double bonds), alkyl aromatic, or branched alkyl group having a length of C 12 ~C 70 and a hydrophilic end group that does not make the compound water-soluble. The compound also has a net neutral charge at the pH of the shampoo composition.

[0181] The shampoo composition of the present invention may contain an aliphatic amphiphilic substance in an amount of about 0.05% to about 14% by weight, about 0.5% to about 10% by weight, about 1% to about 8% by weight of the shampoo composition as part of a pre-formed dispersed gel network phase.

[0182] According to the present invention, a suitable aliphatic amphiphilic substance, or a suitable mixture of two or more aliphatic amphiphilic substances, has a melting point of at least about 27°C. As used herein, the melting point can be measured by the standard melting point method described in U.S.Pharmacopeia, USP-NF General Chapter <741> "Melting range or temperature". The melting point of a mixture of two or more materials is measured by mixing the two or more materials at a temperature higher than their individual melting points and then cooling the mixture. If the resulting composite is a homogeneous solid below about 27°C, the mixture has a melting point suitable for use in the present invention. A mixture of two or more aliphatic amphiphilic substances containing at least one aliphatic amphiphilic substance with an individual melting point below about 27°C is also suitable for use in the present invention as long as the composite melting point of the mixture is at least about 27°C.

[0183] Suitable aliphatic amphiphilic substances of the present invention include fatty alcohols, alkoxylated fatty alcohols, fatty phenols, alkoxylated fatty phenols, fatty amides, alkoxylated fatty amides, fatty amines, fatty alkylamide alkylamines, alkoxylated amines, fatty carbamates, fatty amine oxides, fatty acids, alkoxylated fatty acids, fatty diesters, fatty sorbitan esters, fatty sugar esters, methyl glucoside esters, fatty glycol esters, mono-, di-, and tri-glycerides, polyglycerin fatty esters, alkyl glyceryl ethers, propylene glycol fatty acid esters, cholesterol, ceramides, fatty silicone waxes, fatty glucosamides, and phospholipids, and mixtures thereof.

[0184] In the present invention, the shampoo composition may contain an aliphatic alcohol gel network. These gel networks are formed by combining an aliphatic alcohol and a surfactant at a ratio 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 and the surfactant is compartmentalized into aliphatic alcohol droplets. The surfactant carries water into the aliphatic alcohol together with the surfactant. As a result, isotropic aliphatic alcohol droplets are transformed into liquid crystal phase droplets. When this mixture is cooled to a temperature lower than the chain melting temperature, the liquid crystal phase is converted into a solid crystalline gel network. The gel network contributes to the stabilization effect on cosmetic creams and hair conditioners. In addition, they provide a tactile effect adjusted for hair conditioners.

[0185] The aliphatic alcohol may be contained in the aliphatic alcohol gel network at a concentration of about 0.05% to about 14% by weight. For example, the aliphatic alcohol may be present in an amount in the range of about 1% to about 10% and / or about 6% to about 8% by weight.

[0186] Useful aliphatic alcohols herein include those having from about 10 to about 40 carbon atoms, from about 12 to about 22 carbon atoms, from about 16 to about 22 carbon atoms, and / or from about 16 to about 18 carbon atoms. These aliphatic alcohols may be straight-chain alcohols 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 in a ratio of about 20:80 to about 80:20 of cetyl alcohol to stearyl alcohol is preferred.

[0187] Preparation of the gel network: Fill a container with water and heat the water to about 74 °C. Add cetyl alcohol, stearyl alcohol, and sodium lauryl sulfate surfactant to the heated water. After incorporation, pass the resulting mixture through a heat exchanger where the mixture is cooled to about 35 °C. Upon cooling, the aliphatic alcohol and surfactant crystallize to form a crystalline gel network. Table 1 shows the components and their respective amounts of an exemplary gel network composition.

[0188] [Table 1]

[0189] Emulsifier Various anionic and nonionic emulsifiers can be used in the personal care compositions of the present invention. The anionic and nonionic emulsifiers can be essentially either monomers or polymers. Examples of monomers include, but are not limited to, alkyl ethoxylates, alkyl sulfates, soaps, and fatty acid esters, and derivatives thereof. Examples of polymers include, but are not limited to, polyacrylates, polyethylene glycols, and block copolymers, and derivatives thereof. Naturally occurring emulsifiers such as lanolin, lecithin, and lignin, and derivatives thereof are also non-limiting examples of useful emulsifiers.

Suitable chelating agents include those described in A E Martell & R M Smith, Critical Stability Constants, Vol.1, Plenum Press, New York & London (1974) and A E 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 their derivatives" means salts and derivatives that contain the same functional structure (e.g., the same chemical backbone) as the chelating agent being referenced and have similar or better chelating properties. This term includes alkali metals, alkaline earths, ammonium, substituted ammonium salts (i.e., monoethanolammonium, diethanolammonium, triethanolammonium) salts, esters of chelating agents having an acidic moiety, and mixtures thereof, and in particular, all sodium, potassium or ammonium salts.

[0194] aqueous carrier The personal care composition can be in the form of a liquid that can be poured (under ambient conditions). Thus, such a composition typically contains a carrier, which is present at a concentration of about 40 wt% to about 85 wt%, or about 45 wt% to about 80 wt%, or about 50 wt% to about 75 wt% of the personal care composition. The carrier may include water or a miscible mixture of water and an organic solvent, and in one embodiment, it may contain water with minimal organic solvent or no organic solvent at a significant concentration, except when accidentally incorporated into the composition as a minor component of other essential or optional components.

[0195] Useful carriers for the personal care compositions of the present invention include water and aqueous solutions of lower alkyl alcohols and polyhydric alcohols. Lower alkyl alcohols useful herein are monohydric alcohols having from 1 to 6 carbons, and in one embodiment, ethanol and isopropanol. Exemplary polyhydric alcohols useful herein include propylene glycol, hexylene glycol, glycerin, and propanediol.

[0196] Product Form The personal care compositions of the present invention may be present in typical hair care formulations. The compositions may be in the form of solutions, dispersions, emulsions, powders, talcs, capsules, spheres, spongers, solid dosage forms, foams, and other delivery mechanisms. The compositions of the present invention may be hair tonics, leave-on hair products such as treatments and styling products, rinse-off hair products such as shampoos and personal cleansing products, and treatment products, and any other form that can be applied to the hair.

[0197] Applicator In the present invention, the personal care composition may be dispensed from an applicator for direct dispensing onto the scalp area. By directly dispensing onto the scalp via a targeted delivery applicator, it is possible to deposit the undiluted cleansing agent directly onto the areas that are particularly in need of cleansing. This also minimizes the risk of the cleansing solution getting into the eyes.

[0198] The applicator may be or can be attached to a bottle containing the cleansing personal care composition. The applicator can consist of a base that holds or extends to one or more comb teeth. The comb teeth have openings that can be at the tip, the base, or any point between the tip and the base. These openings allow the product to be dispensed directly from the bottle onto the hair and / or scalp.

[0199] Alternatively, the applicator can consist of brush-like bristles attached to or extending from the base. In this case, the product is dispensed from the base and the bristles allow for the distribution of the product by combing or brushing movements.

[0200] The design and materials of the applicator and the teeth can also be optimized to allow for a scalp massage. In this case, the shape of the teeth or bristles at the tip is advantageously more rounded, similar to the roller ball applicators used for eye cream. The materials can also be smoother and softer, for example, having a metallic or metallic-like finish, a "rubber-like material".

[0201] Method Viscosity measurement The viscosity of the shampoo can be measured using a cone and plate Brookfield RS rheometer equipped with cone C75-1, at a constant shear rate of 2 s -1 for 3 minutes at 27 °C with a 2.5 mL sample.

[0202] The personal care composition of the present invention can have a viscosity of about 3000 cps to about 20,000 cps, can have a viscosity of about 5000 cps to about 15,000 cps, and can have a viscosity of about 8000 cps to about 12,000 cps.

[0203] Measurement of zinc pyrithione (ZPT) adhesion The adhesion of zinc pyrithione (ZPT) to the scalp in vivo can be measured by treating the scalp with a ZPT-containing cleansing composition, rinsing, and then extracting the drug with ethanol. The drug concentration in the ethanol extraction solvent is measured by HPLC. Quantification is performed based on a standard curve. The concentration detected by HPLC is converted to grams per unit of the amount collected by using the concentration multiplied by the volume.

[0204] Next, the mass concentration per volume of the drug measured by HPLC is converted to the mass adhesion per area by multiplying the measured HPLC concentration by the volume of the extraction solvent and dividing by the area of the extracted scalp.

[0205] Results and Non-Limiting Examples

[0206] [Table 2]

[0207] [Table 3] When the total surfactant concentration is less than 10%, typically it does not have a desirable viscosity exceeding 3000 cps. This can be confirmed both with and without a co-surfactant.

[0208] [Table 4-1]

[0209] [Table 4-2]

[0210] [Table 5] When the total surfactant concentration is 10% or more, usually the desired range of viscosity can be achieved. This is observed over a wide range of total surfactant concentrations and anionic surfactant / co-surfactant ratios.

[0211] [Table 6]

[0212] [Table 7] The ratio of anionic surfactant / cosurfactant can produce a desirable viscosity of about 0.63 to about 14. Formulations with a surfactant / cosurfactant ratio greater than about 15, including formulations without cosurfactant, typically cannot achieve a desirable viscosity profile.

[0213] Preparation of Shampoo Composition The personal care composition is prepared by adding a surfactant, an anti-dandruff agent, a fragrance, a viscosity modifier, a cationic polymer, and the balance of water while stirring well to ensure a homogeneous mixture. The mixture can be heated to 50 - 75 °C to accelerate the solubilization of the solubilizing agent and then cooled. To provide the shampoo composition of the present invention suitable for application to human hair and scalp, the product pH can be adjusted as necessary, and the pH can vary from about pH 4 - 9, or about pH 6.5 - 8, or about pH 5.5 - 6.5 based on the selection of specific cleansing surfactants and / or other components.

[0214] Adhesion

[0215] [Table 8]

[0216] [Table 9] In the formula space of anionic surfactant / cosurfactant, as described in Example 19, when the ratio of anionic surfactant to cosurfactant is high (sodium lauryl sulfate:cocamidopropyl betaine = 13:1), the low molecular weight polymer provides adhesion equivalent to the control formulation. Example 18 exceeds the percentage of ethoxylated surfactant that can be targeted and is provided as an example of a benchmark that the present invention can achieve or a benchmark standard.
