Description

[Technical Field]

[0001] The present invention relates generally to silicone-free conditioning shampoo compositions, and more particularly to conditioning shampoo compositions containing polyvinyl alcohol, one or more cationic polymers, and a gel network that provide similar conditioning performance compared to shampoos containing silicone. [Background technology]

[0002] Human hair becomes soiled by contact with the environment and sebum secreted by the scalp, in addition to the use of third-step styling products and hair treatments that leave a visually or tactilely noticeable residue on the hair. Dirty hair can feel unclean and have an unattractive appearance, necessitating regular shampooing.

[0003] Shampooing cleanses hair by removing excess dirt and sebum. However, shampooing can leave hair wet, tangled, and generally unmanageable. When hair dries, it often becomes dry, rough, lackluster, and / or frizzy because the hair's natural oils are removed. Therefore, shampoos that provide cleansing and conditioning benefits to hair (hereinafter "conditioning shampoos") have become popular. Conditioning shampoos often contain silicones that coat the hair shaft, thereby locking in moisture, reducing frizz, and giving hair a desirable soft, silky feel. Silicones can provide these conditioning benefits without interfering with cleansing efficacy.

[0004] However, some consumers prefer silicone-free hair care products.Many substitutes, such as natural oils, are incorporated into shampoo compositions.However, these substitutes are generally less effective and / or make hair look and feel greasy and / or dirty. Summary of the Invention [Problem to be solved by the invention]

[0005] Therefore, there is a need for a silicone-free shampoo composition that provides good conditioning and cleansing benefits. [Means for solving the problem]

[0006] The conditioning shampoo composition comprises: (a) from about 4% to about 25% of a detersive surfactant; (b) from about 0.05% to about 5% of a polyvinyl alcohol; (c) from about 1% to about 8% of a fatty alcohol; (d) from about 0.01% to about 15% of one or more gel network surfactants, the one or more gel network surfactants comprising an anionic surfactant, a cationic surfactant, a zwitterionic surfactant, a nonionic surfactant, or a combination thereof; (e) from about 60% to about 85% of a liquid carrier; and (f) a dispersed gel network phase comprising (i) at least a portion of the fatty alcohol, (ii) at least a portion of the gel network surfactant, and (iii) at least a portion of the liquid carrier, wherein the anionic surfactant and the gel network surfactant are the same or different; the composition is substantially free of silicone; and the composition is liquid. [Brief explanation of the drawings]

[0007] While the specification concludes with claims particularly pointing out and distinctly claiming the subject matter of the invention, it is believed the present invention may be more readily understood from the following description taken in conjunction with the accompanying drawings. [Figure 1A] 1 shows a hair tress washed with Comparative Example C5. [Figure 1B] 1 shows a hair tress washed in Example 1. [Figure 2A] 1 is an image from a scanning electron microscope (SEM) at 1000x magnification of a hair tress washed with Comparative Example C5.

[Figure 2C] 1 is an image from a scanning electron microscope (SEM) at 1000x magnification of a hair tress washed in Example 1. [Figure 2D] 1 is an image from a scanning electron microscope (SEM) at 5000x magnification of a hair tress washed in Example 1. DETAILED DESCRIPTION OF THE INVENTION

[0008] Conditioning shampoo compositions containing various combinations of cleansing surfactants and hair conditioning agents are known. Many of these products contain a combination of anionic surfactants, cationic polymers, and silicones, which function in combination to form coacervates that deposit on the hair during washing and ultimately give the hair a smooth texture and a clean, silky feel.

[0009] However, some consumers desire a silicone-free liquid conditioning shampoo. Formulating a consumer-acceptable silicone-free conditioning shampoo is difficult because silicones are highly effective hair conditioning agents and it is difficult to find compositions that match their performance, especially the smooth, clean feel of dry hair.

[0010] Emulsified non-silicone conditioning actives, such as coconut oil, are initially attractive alternatives to silicones. However, over time, these actives distribute into surfactant micelles within the aqueous phase, reducing the viscosity of the product to a level lower than typically preferred by consumers, making it difficult to effectively spread the product throughout the user's hair. The layered surfactant phase can be effective in stabilizing high levels (1% or more) of emulsified oil. However, these products are generally not preferred by consumers because they typically lather slowly and produce less foam than conventional (micellar) shampoos. Furthermore, when these actives are deposited at the levels required to mimic silicone as a hair conditioning active, dry hair generally appears dirty, oily, and / or greasy.

[0011] It has been found that liquid conditioning shampoos containing polyvinyl alcohol (PVOH), one or more cationic polymers, and a gel network can meet or exceed the performance of silicone. Comparative Example C5 (see Table 2 below) is a shampoo composition containing 0.4% cationic polymer, 2.3% gel network premix, and 3% silicone. Example 1 (see Table 3 below) does not contain silicone and contains 0.4% cationic polymer, 2.3% gel network premix, and 0.5% polyvinyl alcohol. Example 1, which does not contain silicone, had better dry hair performance than Comparative Example C5, as determined by the hair texture analysis test method described below.

[0012] Figure 1A shows a hair tress washed with Comparative Example C5, and Figure 1B shows a hair tress washed with Example 1. Each tress was washed as described in the Hair Texture Analysis Test Method described below. Surprisingly, Figure 1A, which was washed with a shampoo containing 3% silicone, clearly shows more frizz than Example 1, which was washed with a shampoo having 0.5% polyvinyl alcohol but no silicone.

[0013] Figures 2A and 2B are images from a scanning electron microscope (SEM) at 1000x and 5000x magnification, respectively, of a hair tress washed with the silicone-containing shampoo of Comparative Example C5, according to the Hair Texture Analysis Test Method described below. Figures 2C and 2D are SEM images at 1000x and 5000x magnification, respectively, of a hair tress washed with the PVOH-containing but silicone-free shampoo of Example 1, according to the Hair Texture Analysis Test Method described below. Surprisingly, the tresses of Figures 2A and 2B are rougher, with distinct ridges, compared to the tresses of Figures 2C and 2D.

[0014] The shampoo composition may have a viscosity of from 2000 cP (2 Pa·s) to 23,000 cP (23 Pa·s), alternatively from 4000 cP (4 Pa·s) to 14,000 cP (14 Pa·s), alternatively from 4500 cP (4.5 Pa·s) to 12,000 cP (12 Pa·s), alternatively from 5,000 cP (5 Pa·s) to 11,000 cP (11 Pa·s), alternatively from 7,000 cP (7 Pa·s) to 10,000 cP (10 Pa·s), as measured by the Cone and Plate Viscosity Measurement Test Method described herein.

[0015] The shampoo composition may contain 0.05% to 0.05% PVOH, alternatively 0.05% to 2% PVOH, alternatively 0.1% to 1.5% PVOH, alternatively 0.15% to 1% PVOH, alternatively 0.2% to 0.9% PVOH, alternatively 0.2% to 0.5% PVOH. The PVOH may have a degree of hydrolysis of 50% or more, alternatively 80% or more, alternatively 85% or more, alternatively 90% or more. The PVOH may have a viscosity of 1 cP to 100 cP, alternatively 1 cP to 50 cP, alternatively 2 cP to 40 cP, alternatively 3 cP to 35 cP, when measured as a 4% aqueous solution at 20°C. The viscosity of the PVOH is measured according to the PVOH Viscosity Test Method described herein.

[0016] Hair tresses washed and dried according to the Hair Texture Analysis Test Method described below have an average disentangling force of less than 210 gf, alternatively less than 200 gf, alternatively less than 180 gf, alternatively less than 150 gf, alternatively less than 145 gf. Hair tresses washed and dried according to the Hair Texture Analysis Test Method described below have an average disentangling force of from 45 gf to 180 gf, alternatively from 60 gf to 165 gf, alternatively from 65 gf to 145 gf, alternatively from 70 gf to 130 gf, alternatively from 70 gf to 100 gf.

[0029] As used herein, the term "suitable for application to human hair" means that the composition so described or its components are acceptable for use in contact with human hair and scalp and skin without undue toxicity, incompatibility, instability, allergic reaction, etc.

[0030] "Sulfated surfactant" means a surfactant that contains a sulfate moiety. Some non-limiting examples of sulfated surfactants are sodium lauryl sulfate, sodium laureth sulfate, ammonium lauryl sulfate, and ammonium laureth sulfate.

[0031] As used herein, "water-soluble" means that the material is soluble in the water in the composition. Generally, such a material should be soluble in the water solvent at 25°C at a concentration of 0.1%, alternatively 1%, alternatively 5%, alternatively 15% by weight.

[0032] Conditioning shampoo composition As used herein, the term "dispersed gel network" or "gel network" refers to a lamellar and / or vesicular solid crystalline phase comprising at least one fatty alcohol, at least one gel network surfactant, and water or other suitable solvent. This dispersed gel network is further combined with a shampoo base comprising a surfactant system, polyvinyl alcohol, one or more cationic polymers, and a liquid carrier to form a conditioning shampoo composition.

[0033] Dispersed gel network phase The shampoo composition may comprise a dispersed gel network phase in combination with a detersive surfactant to provide the composition with suitable cleaning benefits. The shampoo composition may comprise from 1% to 12%, alternatively from 1% to 7%, alternatively from 1.25% to 6%, alternatively from 1.5% to 5%, alternatively from 2% to 4% of the dispersed gel network phase.

[0034] A suitable dispersed gel network can be formed by combining an aliphatic alcohol and a gel network surfactant in a suitable ratio and heating the dispersion to a temperature above the melting point of the aliphatic alcohol. During this mixing process, the aliphatic alcohol melts, distributing the gel network surfactant and introducing water into the aliphatic alcohol. The mixing of the gel network surfactant and the aliphatic alcohol also causes the isotropic aliphatic alcohol droplets to change into liquid crystalline phase droplets. Subsequently, when the mixture is cooled below the melting transition temperature of the aliphatic alcohol, the liquid crystal phase is transformed into a solid crystalline gel network. Further details of suitable gel networks are described in G.M. Eccleston, "Functions of Mixed Emulsifiers and Emulsifying Waxes in Dermatological Lotions and Creams," Colloids and Surfaces A: Physiochem. and Eng. Aspects 123-124 (1997) 169-182, and in "The Microstructure of Semisolid Creams" by G.M. Eccleston, Pharmacy International, Vol. 7, 63-70 (1986), each of which is incorporated herein by reference.

[0035] In some embodiments, it may be desirable to preform the gel network phase, meaning that at least 50 percent of the mixture of fatty alcohol, gel network surfactant, and liquid carrier is in a substantially solid crystalline phase before being added to the other components of the shampoo composition. When the dispersed gel network is preformed, the gel network component can be prepared as a separate premix, which, after cooling, can then be incorporated with the detersive surfactant and any other components of the shampoo composition. Without intending to be bound by theory, it is believed that incorporating the preformed gel network component with the detersive surfactant and other components of the shampoo composition results in the formation of a substantially equilibrated lamellar dispersion ("ELD") in the final composition. The ELD is a lamellar or vesicular dispersed phase resulting from the preformed gel network component in substantial equilibrium with the detersive surfactant, carrier, and other optional components of the shampoo composition. This equilibrium occurs upon incorporation of the preformed gel network component into the other components of the shampoo composition and can be effectively completed within about 24 hours after incorporation. If the components including the gel network component (i.e., fatty alcohol, gel network surfactant, and liquid carrier) are added as individual components with the other components of the shampoo composition in a single mixing step, and not as separate preformed gel network components, an ELD will not form.

[0036] The presence of gel network in premix and shampoo compositions can be confirmed by means well known to those skilled in the art.For example, X-ray analysis, optical microscopy, electron microscopy, and differential scanning calorimetry can be used to identify gel network.Suitable X-ray analysis is described in U.S. Patent Application Publication No. 2006 / 0024256, which is incorporated herein by reference.

[0037] In some aspects, the scale size of the dispersed gel network in the shampoo composition can range from 10 nm to 500 nm (eg, 0.5 μm to 10 μm, or 10 μm to 150 μm).

[0038] The scale size distribution of the dispersed gel network in a shampoo composition can be measured by laser light scattering technology using a Horiba Model LA910 Laser Scattering Particle Size Distribution Analyzer (Horiba Instruments, Inc., Irvine, California, USA). The scale size distribution in a shampoo composition can be measured by combining 1.75 g of shampoo composition with 30 mL of 3% NH4Cl, 20 mL of 2% Na2HPO4 7H2O, and 10 mL of 1% Laureth-7 to form a mixture. This mixture is then stirred for 5 minutes. Depending on the particular Horiba instrument used, a sample ranging from 1 to 40 mL is taken and then injected into a Horiba instrument containing 75 mL of 3% NH4Cl, 50 mL of 2% Na2HPO4 7H2O, and 25 mL of 1% Laureth-7 until the Horiba instrument reads 88-92% T, which is the required value for the scale size measurement. Once this is achieved, after 2 minutes of circulation, it is measured by Horiba instrument, and the scale size measurement is obtained.This subsequent measurement is carried out using a sample of shampoo composition that is heated to a temperature above the melting transition temperature of all fatty materials present in the shampoo composition, in order to ensure that the dispersed gel network is melted.This subsequent measurement obtains a scale size distribution for all remaining materials in the shampoo composition, which can then be compared with the scale size distribution of the initial sample to aid in analysis.

[0039] Gel network fatty alcohol The dispersed gel network phase may comprise a fatty alcohol (e.g., a C10-C40 fatty alcohol) at 0.05% or more by weight of the composition (e.g., 0.05% to 25%, 0.5% to 20%, or 1% to 8%). The fatty alcohol may be linear or branched, saturated or unsaturated. As can be appreciated, suitable fatty alcohols may be of natural, vegetable, or synthetic origin. In some embodiments, it may be desirable to blend several fatty alcohols, such as, for example, a mixture of cetyl alcohol and stearyl alcohol in a ratio of 20:80 to 80:20, to provide a dispersed gel network phase having a melting transition temperature of 38°C or greater. Some non-limiting examples of fatty alcohols that may be suitable for use herein include cetyl alcohol, stearyl alcohol, arachidyl alcohol, behenyl alcohol, C 21 Fatty alcohol (1-heneicosanol), C 23 Fatty alcohol (1-tricosanol), C 24 Fatty alcohols (lignoceryl alcohol, 1-tetracosanol), C 26 Aliphatic alcohol (1-hexacosanol), C 28 Fatty alcohol (1-octacosanol), C 30 Fatty alcohol (1-triacontanol), C 20~40 Alcohol (e.g., Performacol® 350 Alcohol and 425 Alcohol available from New Phase Technologies), C 30~50 Alcohol (e.g., Performacol® 550 Alcohol), C 40~60 Alcohol (eg, Performacol® 700 Alcohol), or mixtures thereof.

[0040] The shampoo composition may include a fatty alcohol, at least a portion (if not a majority) of which is part of the dispersed gel network phase. The composition may comprise at least 1%, alternatively 1% to 8%, alternatively 1.25% to 6%, alternatively 1.5% to 5%, alternatively 2% to 5%, alternatively 2% to 4%, by weight of the shampoo composition.

[0041] In one example, the weight ratio of fatty alcohol to gel network surfactant in the gel network component is greater than 1:9, alternatively between 1:5 and 100:1, alternatively between 1:1 and 50:1.

[0042] Gel Network Surfactant The shampoo composition may include a gel network surfactant, at least a portion (if not a majority) of which is part of the dispersed gel network phase. The composition may include from 0.01% to 15%, alternatively from 0.1% to 10%, alternatively from 0.2% to 5% of the gel network surfactant, by weight of the shampoo composition.

[0043] The gel network surfactant can be any suitable anionic surfactant, zwitterionic surfactant, amphoteric surfactant, cationic surfactant, nonionic surfactant, or mixtures thereof, as described herein. In some examples, the gel network surfactant is sulfate-free or substantially sulfate-free. The detersive surfactant and gel network surfactant can be independently selected and can be the same or different. In some embodiments, the gel network surfactant has a hydrophobic end group having a chain length of 10 to 40 carbon atoms. The hydrophobic end group can be alkyl, alkenyl (containing up to three double bonds), alkylaromatic, or branched alkyl. Mixtures of two or more gel network surfactants can also be used. Some non-limiting examples of gel network surfactants are disclosed in U.S. Patent Application Publication No. 2006 / 0024256.

[0044] Water or a suitable solvent The dispersed gel network phase may also contain water or a suitable solvent. Both the water or suitable solvent and the gel network surfactant are involved in the swelling of the fatty alcohol. This in turn leads to the formation and stability of the gel network. As used herein, the term "suitable solvent" refers to any solvent that can be used in place of or in combination with water in the formation of the gel network.

[0045] The shampoo composition may include water or a suitable solvent as part of the pre-formed dispersed gel network component in an amount suitable to obtain a gel network when combined with the fatty alcohol and gel network surfactant according to the present invention.

[0046] The shampoo composition may include at least 0.05% water or suitable solvent, by weight of the shampoo composition, as part of the pre-formed dispersed gel network component.

[0047] The shampoo composition may include water or a suitable solvent as part of a pre-formed dispersed gel network phase in an amount of at least a 1:1 weight ratio relative to the amount of fatty alcohol.

[0048] Shampoo base material The dispersed gel network phase can be dispersed in a shampoo base. The shampoo base can include a cationic deposition polymer, a surfactant, a co-surfactant, an aqueous carrier, and additional components. The resulting shampoo composition can be substantially free of silicone. As used herein, substantially free of silicone means that the level of silicone components, if present, is 0.1% or less, alternatively 0.05% or less, alternatively 0.01% or less, or alternatively 0%.

[0049] Cationic Deposition Polymer The V shampoo composition may include a cationic deposition polymer. The cationic deposition polymer is included to effectively enhance the deposition of the gel network components. The cationic deposition polymer may include any cationic polymer that enhances the deposition of the gel network from the shampoo to the hair and / or scalp.

[0050] The concentration of the deposition aid in the shampoo composition is sufficient to effectively enhance deposition of the gel network component and may range from 0.05% to 5%, alternatively from 0.075% to 2.5%, alternatively from 0.1% to 1.0%, alternatively from 0.3% to about 0.9%, and 0.4% to about 0.8%, by weight of the shampoo composition.

[0051] Further, the weight ratio of the amount of cationic deposition polymer to PVOH in the shampoo composition may range from 0.4 to 10, alternatively from 0.5 to 8, alternatively from 0.75 to 5, alternatively from 1 to 4.

[0052] The cationic charge density of suitable cationic deposition polymers may be at least 0.4 meq / g, alternatively at least 0.7 meq / g, alternatively at least 1.2 meq / g, alternatively at least 1.5 meq / g, alternatively less than 7 meq / g, alternatively less than 5 meq / g, at the pH of the intended use of the composition. The pH will generally range from pH 3 to pH 9, alternatively from pH 4 to pH 8. The "cationicity" of a polymer, as that term is used herein, refers to the ratio of the number of positive charges on the polymer to the molecular weight of the polymer. The weight average molecular weight of such suitable cationic polymers is generally 10,000 to 10,000,000, alternatively 50,000 to 5,000,000, alternatively 100,000 to 3,000,000.

[0053] Suitable cationic polymers for use in the present composition include polysaccharide polymers such as cationic cellulose derivatives and cationic starch derivatives, such as salts of hydroxyethylcellulose reacted with trimethylammonium-substituted epoxides.Other suitable cationic polymers include cationic guar gum derivatives, such as guar hydroxypropyltrimonium chloride.Further suitable cationic polymers include galactomannan polymer derivatives with a mannose to galactose ratio of greater than 2:1 on a monomer-to-monomer basis, such as cassia gum hydroxypropyltrimonium chloride.A particularly suitable cationic adhesion polymer is guar hydroxypropyltrimonium chloride.

[0054] The cationic guar polymer may be formed from a quaternary ammonium compound. In one embodiment, the quaternary ammonium compound for forming the cationic guar polymer conforms to the following general formula 1:

[0055] [ka] wherein R3, R4, and R5 are methyl or ethyl groups, and R6 is an epoxyalkyl group of general formula 2, or

[0056] [ka] or R6 is a halohydrin group of general formula 3,

[0057] [ka] In the formula, R7 is C1-C3 alkylene, X is chlorine or bromine, and Z is an anion such as Cl-, Br-, I-, or HSO4-.

[0058] In one embodiment, the cationic guar polymer conforms to general formula 4:

[0059] [ka] wherein R8 is guar gum, R4, R5, R6, and R7 are as defined above, and Z is a halogen. In one embodiment, the cationic guar polymer conforms to Formula 5.

[0060] [ka]

[0061] Suitable cationic guar polymers include cationic guar gum derivatives such as guar hydroxypropyltrimonium chloride. In one embodiment, the cationic guar polymer is guar hydroxypropyltrimonium chloride. Specific examples of guar hydroxypropyltrimonium chloride include the Jaguar® series available from Rhone-Poulenc Incorporated, such as Jaguar® C-17, which has a cationic charge density of 0.6 meq / g and a molecular weight of 2,200,000 g / mol and is available from Rhodia Company. Jaguar® C13S has a molecular weight of 2,200,000 g / mol and a cationic charge density of 0.8 meq / g (available from Rhodia Company). N-Hance 3196 has a charge density of 0.7 and a molecular weight of 1,100,000 g / mol and is available from ASI. BF-13 is a borate-free guar with a charge density of 1.1 meq / g and a molecular weight of 800,000, and BF-17 is a borate-free guar with a charge density of 1.7 meq / g and a molecular weight of 800,000, both available from ASI.

[0062] The combination of cationic polymers can improve the conditioning benefits and foaming properties of shampoo compositions. The use of a cationic polymer having a charge density of 0.4 meq / g to 0.8 meq / g, or even 0.7 meq / g, in combination with a cationic polymer having a molecular weight greater than 1,000,000 can result in shampoo compositions that have both foam stability and creaminess.

[0063] In one embodiment, the shampoo composition may comprise a combination of cationic guar and cationic polysaccharide attachment polymer, wherein the corresponding weight ratio of guar to polysaccharide attachment polymer is greater than 2:1, alternatively the weight ratio of guar to polysaccharide attachment polymer is greater than 3:1, alternatively the weight ratio of guar to polysaccharide attachment polymer is greater than 4:1.

[0064] In another embodiment, the shampoo composition may include a combination of only cationic guar polymers, where one cationic guar has a charge density of 1.7 meq / g and another cationic guar has a molecular weight of 1,100,000 g / mole.

[0065] In yet another embodiment, the shampoo composition may include a mixture of 3196 guar and BF-17 cationic guar, where the weight ratio of these two cationic deposition polymers is 5:1, alternatively 2:1, alternatively 1:1, and further alternatively 1:2, or alternatively 2:5, of 3196 to BF-17, respectively.

[0066] Additional examples of suitable cationic polymers are disclosed in US Patent Application Serial No. 17 / 960,862.

[0067] surfactant system Shampoo compositions can include a surfactant system having one or more anionic detersive surfactants and, optionally, one or more additional surfactants. Such surfactants should be physically and chemically compatible with the components described herein or not unduly impair product stability, aesthetics, or performance. Shampoos can contain from 5% to 50%, alternatively from 8% to 30%, alternatively from 8% to 20%, alternatively from 10% to 18%, by weight of the composition.

[0068] Anionic Detersive Surfactants The shampoo composition may include one or more detersive surfactants in the shampoo base to provide cleansing performance. The concentration of anionic surfactant in the shampoo composition is sufficient to provide the desired cleaning and foaming performance, and may generally range from 4% to 25%, alternatively from 8% to 20%, alternatively from 8% to 15%, alternatively from 10% to 14%, by weight of the composition.

[0069] Additional anionic surfactants suitable for use herein include those of the formula ROSO3M and RO(C2H4O) x Included are alkyl and alkyl ether sulfates of the formula SO3M, where R is alkyl or alkenyl of 8 to 18 carbon atoms, x is 1 to 10, and M is a water-soluble cation such as ammonium, sodium, potassium, and triethanolamine cation, or a salt of a divalent magnesium ion with two anionic surfactant anions.

[0088] Methods for Making Personal Care Compositions The compositions described herein can be made using conventional methods. In some embodiments, the compositions can be made by (a) combining a fatty alcohol, a gel network surfactant, and water at a temperature sufficient to partition the gel network surfactant and water into the fatty alcohol to form a premix, (b) cooling the premix below the chain melting temperature of the fatty alcohol to form a gel network, and (c) adding the gel network to a shampoo base comprising one or more detersive surfactants, a cationic polymer, polyvinyl alcohol, and a liquid carrier to form a conditioning shampoo composition comprising a dispersed gel network phase having a melting transition temperature of at least 38°C.

[0089] In some embodiments, the gel network phase can be prepared by heating and mixing a fatty alcohol, a gel network surfactant, and water to a level ranging from 75° C. to 90° C. The mixture can be cooled (e.g., by passing the mixture through a heat exchanger) to 27-35° C. As a result of this cooling step, at least 50 percent of the mixture of fatty alcohol and gel network surfactant crystallizes to form a crystalline gel network.

[0090] Other methods of preparing the gel network phase include heating the fatty alcohol, gel network surfactant, and water while sonicating and / or milling these components to reduce the particle size of the dispersed gel network phase. This increases the surface area of ​​the gel network phase and allows the gel network surfactant and water to swell the gel network phase. Another variation for preparing the gel network involves first heating and mixing the fatty alcohol and gel network surfactant, and then adding this mixture to water.

[0091] How to use The shampoo composition can be used in a conventional manner to cleanse and condition hair.The effective amount of the composition for use is generally in the range of 1 g to 50 g (for example, 1 g to about 20 g).Generally, the method of treating hair can include wetting the hair, squirting an effective amount of the liquid conditioning shampoo composition into the palm of the user's hand, applying the composition to the hair by massaging the composition into the hair and scalp until the composition lathers, working the composition through the hair, and then rinsing the composition.

[0092] In some embodiments, a method for treating hair or skin may include the steps of: (a) wetting the hair or skin with water; (b) applying an effective amount of a personal care composition to the hair or skin; and (c) rinsing the applied skin or hair with water. These steps can be repeated as many times as desired to achieve the desired cleansing and conditioning benefits.

[0093] Test Method Cone and Plate Viscosity Measurement The viscosity of the examples is measured with a Brookfield Rheometer R / S Plus Cone / Plate Controlled Stress manufactured by Brookfield Engineering Laboratories (Stoughton, MA). The cone used (Spindle C-75-1) has a diameter of 75 mm and an angle of 1°. The viscosity is measured at a constant shear rate of 2 s -1 A steady-state flow experiment is used to determine the liquid viscosity at 26.7°C. The sample size is 2.5 mL to 3 mL, and the total measurement read time is 3 minutes.

[0094] PVOH viscosity method The viscosity of PVOH was measured as a 4% aqueous solution using a Brookfield DV-II+ Procup and Bob viscometer equipped with an ultra-low viscosity adapter. The measurement geometry was a cylindrical type 0 rotor. The sample temperature was 20°C. The shear rate was adjusted to accommodate different PVOHs with different viscosities while maintaining the torque within the range of 60-80%.

[0095] Hair Texture Analysis Method hair base material General population Chinese hair, weighing 4 grams and measuring 8 inches in length in a round ponytail tress, was purchased from International Hair Importers & Products Inc. (87-29 Myrtle Ave., Glendale, NY 11385) and used in the following hair treatment procedure: Each test product was applied to three separate tresses (n=3).

[0096] Hair treatment A 0.4 g (0.1 g per 1 g of hair) of conditioning shampoo (e.g., Composition A) was applied to a hair tress that had first been pre-wetted with 100-105°F water and then squeezed to remove excess water. The product was applied to the tress in a zigzag pattern, evenly to the front and back of the tress (0.2 g per side). The tress was then brushed using a Goody Brush with large, stiff plastic bristles, alternating between the front and back of the tress at approximately one stroke per second for 30 strokes, for a total of 30 seconds. The tress was then rinsed for 30 seconds using 100-105°F water, milking the switch at approximately one stroke per second. The tress was squeezed to remove excess water. The test product was then reapplied to the tress a second time, following the same procedure as above, and then rinsed from the tress.

[0097] Combing force measurement The force required to comb the treated hair tresses (wet and dry) was measured using a Texture Analyzer TA-XT Plus (Stable Micro Systems), an Instron 5542 (Instron) or equivalent force measuring device, which is the industry standard method for measuring wet / dry hair combing force as disclosed by TRI Princeton.

[0098] The hair tress is placed in the holder of the Texture Analyzer, secured at its root end. The hair tresses are positioned in series within the comb and then pulled through the comb by the Texture Analyzer while recording the average force pulling the hair tress through each comb (=1 combing stroke). The hair tress is removed from the comb and returned to its pre-combing position. The hair tress is then combed nine more times using the same combing procedure. The output includes the work to detangle (gram force, gf) and tip combing (tip resistance). [Example]

[0103] [Table 3] * Values ​​represent the average (mean) gram force (gf) values ​​from the second to sixth combing strokes (out of a 10 stroke test) using a sample size of n=3 tresses per product. Lower values ​​represent lower combing force and better conditioning benefits, which are preferred for the present invention. Product names and suppliers in Tables 2 and 3: (1) Sodium laureth-n sulfate (wherein n is 1 or more and 3 or less) (2) PVOH 3-80 (Kuraray Poval (registered trademark)) (3) PVOH 32-80 (Kuraray Poval (registered trademark)) (4) PVOH 3-98 (Kuraray Poval (registered trademark)) (5) N-Hance® 3196 (Ashland®) (6) Jaguar® C500 (Solvay®) (7) Polymer JR30M (Dow®) (8) Mirapol® 100S (SNF) (9) Thixcin® R (Elementis®) (10) Purified EGDS (Evonik®) (11) Rheocare® TTA (BASF®) (12) 330M Silicone (Momentive®)

[0104] Examples 1, 2, and 7 had, on average, improved detangling power and wet combing compared to Comparative Examples C1-C5. It is interesting to note that C5 contains a cationic polymer, a gel network, and 3% silicone, while Examples 1, 2, and 7 are silicone-free and have 0.2-0.5% PVOH, and perform better than C5. The examples in Table 3 are considered to have consumer-acceptable detangling power and wet combing.

[0105] The data in Table 4 below show the results of consumer testing on Chinese female consumers aged 18-45. Three separate test groups, each with eight consumers, used the test product in place of their regular shampoo product for one week. The consumers then gave each product an overall rating using a sliding rating scale ranging from 1 (did not like this shampoo) to 100 (like this shampoo). The scores for each test group were averaged (mean value), and then the scores were normalized to allow comparisons between test groups. Individual product test scores were normalized by the highest test score obtained for the silicone control shampoo (C3) (94 - Test Group 2). The non-silicone shampoo (Example 1) was found to be nearly as well-received by consumers as the silicone-containing control C5.
