Description

Technical Field

[0001] The present invention relates to a hair care composition containing a combination of one or more cationic polymers of a given molecular weight and charge density and a lower concentration of a surfactant, which provides a solubilizer attachment effect.

Background Art

[0002] For many years, anti-dandruff shampoos have been widely used for dandruff treatment and hair and scalp cleaning, but there is still a need for improved anti-dandruff shampoos. Generally, anti-dandruff shampoos are formulated by combining an anti-dandruff agent with a surfactant and an aqueous solution system that aims to adhere the anti-dandruff agent onto the scalp. The anti-dandruff agent can be insoluble fine particles such as zinc pyrithione and / or surfactant-soluble substances such as climbazole or octopirox. Many anti-dandruff shampoos use a cationic polymer together with an anionic surfactant to form coacervates that help the attachment of insoluble fine particle agents such as zinc pyrithione or silicone droplets. In most cases, coacervates are formed upon dilution of the shampoo and capture the insoluble fine particle agents with their formation. When the coacervates adhere to the hair and scalp, the captured insoluble fine particle agents also adhere.

Summary of the Invention

Problems to be Solved by the Invention

[0003] However, it is believed that the coacervate does not affect the deposition of the soluble agent because the soluble agent is soluble in the continuous surfactant phase of the shampoo, which makes it difficult to trap the coacervate during coacervate formation upon shampoo dilution. Thus, it may prove difficult to deposit more than 1%-2% of the soluble agent present in the anti-dandruff shampoo on the scalp while rinsing off the remaining 98%-99% of the soluble agent in the formulation. Since many of the anti-dandruff agents can be relatively expensive, having >97% of the soluble agent washed off is like throwing money down the drain, so there remains a need for shampoos that can deposit soluble anti-dandruff agents more efficiently. Also, consumers continue to desire shampoos that deliver superior anti-dandruff benefits, and the lower the agent deposition, the less anti-dandruff effect, so there remains a need for shampoos that can deposit a high percentage of the soluble agent present in the anti-dandruff shampoo on the scalp.

[0004] Surprisingly, the molecular weight is about 250,000 to about 2,500,000 g / mol, the charge density is about 0.25 to about 7.0 meq / g, and the charge density of the polymer is about 8×10 of the molecular weight. -7 It has been found that hair care compositions comprising a combination of one or more cationic polymers having a .times.-1.5 minus value greater than or equal to zero and low levels of surfactants provide soluble agent deposition benefits. [Means for solving the problem]

[0005] 8% to 16% of one or more surfactants, 0.01% to 10% of one or more surfactant-soluble antidandruff agents, and 0.01% to 5% of one or more cationic polymers having a molecular weight (MW) of about 250,000 to about 2,600,000 g / mol and a charge density (CD) of about 0.25 to about 7.0 meq / g, and -7* A hair care composition having a MW-1.5≧0, wherein the composition has a deposition efficiency of about 1.4 to about 3 times that of a control composition, the control composition having a pH of about 6, comprising 14% SLE1S, no polymeric component, and 1% surfactant-soluble anti-dandruff agent.

These cationic polymers can include at least one of (a) cationic guar polymers, (b) cationic non - guar galactomannan polymers, (c) cationic tapioca polymers, (d) cationic copolymers of acrylamide monomers and cationic monomers, and / or (e) synthetic non - crosslinked cationic polymers which may or may not form lyotropic liquid crystals when combined with a detergency surfactant, (f) cationic cellulose polymers. Further, the cationic polymer may be a mixture of cationic polymers.

[0056] The hair care composition can include a cationic guar polymer which is a cationically substituted galactomannan (guar) gum derivative. The guar gum used in the preparation of these guar gum derivatives is typically obtained as a material naturally produced from the seeds of the guar plant. The guar molecule itself is a linear mannan that branches at regular intervals where single - unit galactose units are alternately on the mannose units. The mannose units are linked to each other by β(1 - 4) glycosidic bonds. The galactose branches occur by α(1 - 6) bonds. The cationic derivatives of guar gum are obtained by the reaction between the hydroxyl groups of the polygalactomannan and a reactive quaternary ammonium compound. The degree of substitution of the cationic groups on the guar structure must be sufficient to provide the required cationic charge density described above.

[0057] In the present invention, examples of the cationic polymer include, but are not limited to, cationic guar polymers having a weight average molecular weight of less than 2,200,000 g / mol, or about 150,000 to about 2,200,000 g / mol, or about 200,000 to about 2,200,000 g / mol, or about 250,000 to about 2,500,000 g / mol, or about 300,000 to about 1,200,000 g / mol, or about 700,000 (700,000 thousand) to about 1,000,000 g / mol. Further, the cationic guar polymer can have a charge density of about 0.2 to about 2.2 meq / g, or about 0.3 to about 2.0 meq / g, or about 0.4 to about 1.8 meq / g, or about 0.5 meq / g to about 1.8 meq / g.

[0058] The cationic guar polymer can have a weight average molecular weight of less than about 1,500,000 g / mol and can have a charge density of about 0.1 meq / g to about 2.5 meq / g. The cationic guar polymer can have a weight average molecular weight of less than 900,000 g / mol, or about 150,000 to about 800,000 g / mol, or about 200,000 to about 700,000 g / mol, or about 300,000 to about 700,000 g / mol, or about 400,000 to about 600,000 g / mol, about 150,000 to about 800,000 g / mol, or about 200,000 to about 700,000 g / mol, or about 300,000 to about 700,000 g / mol, or about 400,000 to about 600,000 g / mol. The cationic guar polymer can have a charge density of about 0.2 to about 2.2 meq / g, or about 0.3 to about 2.0 meq / g, or about 0.4 to about 1.8 meq / g, or about 0.5 meq / g to about 1.5 meq / g.

[0067] The hair care composition of the present invention may contain a galactomannan polymer derivative having a mannose to galactose ratio of more than 2:1 on a monomer-to-monomer basis, and this 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 is added. The term "amphoteric galactomannan" refers to a galactomannan polymer to which a cationic group and an anionic group are added so 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 are branched 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 ratio of mannose monomers to galactose monomers varies depending on the plant species and is also affected by climate. The non-guar galactomannan polymer derivative of the present invention has a ratio of mannose to galactose greater than 2:1 on a monomer-to-monomer basis. A suitable ratio of mannose to galactose may be greater than about 3:1, and the ratio of mannose to galactose may be greater than about 4:1. Analysis of the ratio of mannose to galactose 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 polymers are typically obtained as natural substances such as plant seeds 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 hair care composition of the present invention can further 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 the cationic group on the galactomannan structure needs to be sufficient to provide the required cationic charge density.

[0072] The galactomannan polymer derivative can be a cationic derivative of a non-guar galactomannan polymer, which is obtained by reacting a hydroxyl group of the 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 that conform 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,

[0074]

[0075] [Chemical formula]

[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 anionic groups.

[0077] The 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] The hair care composition can include a water-soluble cationically modified starch polymer. As used herein, the term "cationically modified starch" refers to starch to which a cationic group has been added before the starch is decomposed into smaller molecular weights, or starch to which a cationic group has been added after the modification of the starch to reach the desired molecular weight. The definition of the term "cationically modified starch" includes amphoterically modified starch. The term "amphoterically modified starch" refers to a starch hydrolyzate to which a cationic group and an anionic group have been added.

[0079] The cationically modified starch polymer disclosed in the present invention has a percentage of bound nitrogen of about 0.5% to about 4%.

[0080] The cationic modified starch polymer used in the hair care composition 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 hair care composition may contain a cationic modified starch polymer having a charge density of about 0.2 meq / g to about 5 meq / g and / or about 0.2 meq / g to about 2 meq / g. Chemical modifications for obtaining such a charge density include, but are not limited to, adding amino groups and / or ammonium groups to the starch molecule. Non-limiting examples of these ammonium groups 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 it is degraded to a smaller molecular weight, or the cationic groups may be added after such modification.

[0082] Cationic modified starch polymers typically have 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 anhydroglucose unit derivatized by a substituent. Each anhydroglucose 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 mol average basis as the number of moles of substituent per mole of anhydroglucose 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 prior to 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, amylase, potato starch, tapioca starch, oat starch, sago starch, sticky rice, or mixtures thereof.

[0084] The cationically modified starch polymer can be selected from hydrolyzed 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 may include one or more additional modifications before being decomposed to a smaller molecular weight or before being modified. For example, these modifications can include crosslinking, stabilization reactions, phosphorylation reactions, and hydrolysis. Stabilization reactions can include alkylation and esterification.

[0086] The cationically modified starch polymer may 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 or mechanically decomposed starch (e.g., by the input of thermomechanical energy in a processing device), or combinations thereof.

[0087] The optimal form of starch is one that readily solubilizes in water and forms a substantially clear 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 nanometers is suitable for characterizing the transparency of cosmetic compositions.

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

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

[0090] The hair care composition can include a cationic copolymer of an acrylamide monomer and a cationic monomer, and this copolymer has a charge density of about 1.0 meq / g to about 3.0 meq / g.

Non-limiting examples of such counterions include halides (e.g., chlorine, fluorine, bromine, iodine), sulfates, and methyl sulfates.

[0126] The cationic polymers described herein can help 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 seal in moisture and prevent further damage. Chemical treatment damages the hair cuticle and the protective F-layer is stripped away from the hair. As the F-layer is stripped away, the hair becomes more hydrophilic. Applying a lyotropic liquid crystal to chemically treated hair has been found to make the hair more hydrophobic and to have an appearance and feel similar to 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 and protects the hair fiber in the same way that the natural F-layer protects the hair. The hydrophobic layer returns the hair to a healthier state, typically similar to that of untreated hair. The lyotropic liquid crystal is formed by combining the synthetic cationic polymers described herein with the anionic detersive surfactant component of the hair care composition. 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 hair care compositions that have improved conditioning performance for damaged hair.

[0151] gel network In the present invention, a gel network may be present. The gel network component of the present invention contains at least one kind of aliphatic amphiphilic substance. As used herein, "aliphatic amphiphilic substance" refers to a hydrophobic end 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 render the compound water-soluble, and the compound also has a net neutral charge at the pH of the shampoo composition.

[0152] The shampoo composition of the present invention contains an aliphatic amphiphilic substance in an amount of about 0.05% to about 14%, about 0.5% to about 10%, and about 1% to about 8% by weight of the shampoo composition as part of a pre-formed dispersed gel network phase.

[0153] 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 above 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 if the composite melting point of the mixture is at least about 27 °C.

[0154] 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, fatty alkyoxyalted 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 glucose amides, and phospholipids, and mixtures thereof.

[0155] The shampoo composition may contain an aliphatic alcohol gel network. These gel networks are formed by adding an aliphatic alcohol and a surfactant in 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 distributes the surfactant into the 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 provides a stabilizing effect on cosmetic creams and hair conditioners. In addition, they provide a tactile effect adjusted for hair conditioners.

[0156] The aliphatic alcohol may be contained in the aliphatic alcohol gel network at a concentration of about 0.05% by weight 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%.

[0157] Aliphatic alcohols useful in the present invention 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 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 of cetyl alcohol and stearyl alcohol in a ratio of about 20:80 to about 80:20 is preferred.

[0158] Preparation of Gel Network: Fill a container with water and heat the water to about 74 °C. Add cetyl alcohol, stearyl alcohol, and SLES 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 the exemplary gel network composition.

The propellant or foaming agent may be liquefied when enclosed under pressure in a conventional aerosol container. The rapid boiling of the propellant or foaming agent as it exits from an aerosol foam dispenser can serve to spray or foam the other components of the hair care composition.

[0165] Examples of aerosol propellants or foaming agents that can be used in aerosol compositions include chemically inert hydrocarbons such as propane, n-butane, isobutane, cyclopropane, and mixtures thereof, and halogenated hydrocarbons such as dichlorodifluoromethane, 1,1-dichloro-1,1,2,2-tetrafluoroethane, 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, and mixtures thereof. The propellant or foaming agent may contain hydrocarbons such as isobutane, propane, and butane, and these materials can be used due to their low ozone reactivity and can be used as individual components when the vapor pressure ranges from about 1.17 bar to about 7.45 bar, alternatively from about 1.17 bar to about 4.83 bar, or alternatively from about 2.14 bar to about 3.79 bar at 21.1 °C.

The composition may have about 0.5% to about 7% fragrance.

[0169] Such optional ingredients must be physically and chemically compatible with the ingredients of the composition and must not unduly impair the stability, aesthetics, or performance of the product. The CTFA Cosmetic Ingredient Handbook, 10th Edition (published by Cosmetic, Toiletry, and Fragrance Association, Inc. (Washington, D.C.)) (2004) (hereinafter "CTFA") describes various non-limiting materials that can be added to the compositions of this specification.

[0170] 1. Conditioning Agent The conditioning agent of the hair 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 wt% to about 10 wt%, about 0.1 wt% to about 8 wt%, about 0.1 wt% to about 5 wt%, and / or about 0.2 wt% to about 3 wt% 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 No. 5,104,646, and U.S. Patent No. 5,106,609, the disclosures of which are incorporated herein by reference.

[0171] The silicone conditioning agent for use in the compositions of the present invention may have a viscosity of about 20 to about 2,000,000 centistokes ("csk"), about 1,000 to about 1,800,000 csk, about 10,000 to about 1,500,000 csk, and / or about 20,000 to about 1,500,000 csk as measured at 25°C.

[0172] The discrete silicone conditioning agent particles typically have a volume average particle size in the range of about 0.01 micrometer to about 60 micrometers. When applying small particles to the hair, the volume average particle size is typically in the range of about 0.01 micrometer to about 4 micrometers, about 0.01 micrometer to about 2 micrometers, or about 0.01 micrometer to about 0.5 micrometer.

[0173] 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), which is incorporated herein by reference.

[0174] Suitable silicone emulsions for use in the present invention include, but are not limited to, emulsions of insoluble polysiloxanes. These can be prepared via emulsion polymerization according to the descriptions provided in U.S. Patent No. 6,316,541, or U.S. Patent No. 4,476,282, or U.S. Patent Application Publication No. 2007 / 0276087, or they can be emulsified after polymerization is complete via various emulsification methods such as those described in U.S. Patent No. 9,255,184 (B2), or U.S. Patent No. 7,683,119, or Emulsions and Emulsion Stability, edited by Johan Sjoblom, CRC Press, 2005. These references can be considered for a non-limiting list of suitable emulsifiers and emulsifier formulations based on the functionality of the silicone used, the emulsification method, and the desired emulsion particle size. 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, for example, in the range of about 15 nm to about 5 micrometers, about 20 nm to about 1 micrometer, about 25 nm to about 550 nm, or about 1 to 10 micrometers. The concentration of the dispersed silicone in the emulsion can be in the range of about 5 to 90 weight percent, or 20 to 85 weight percent, or 30 to 80 weight percent of the emulsion composition.

[0175] The average molecular weight of the insoluble polysiloxane, the internal phase viscosity of the insoluble polysiloxane, the viscosity of the silicone emulsion, and the diameter 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 a spindle 6 at 2.5 rpm. The silicone emulsion may further contain an additional emulsifier together with an anionic surfactant.

[0176] Other classes of silicones 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 those containing a highly crosslinked polysiloxane system; vi) high refractive index silicones having a refractive index of at least 1.46; and vii) mixtures thereof.

[0177] The conditioning agent of the hair care composition of the present invention may further contain at least one organic conditioning material such as oil or wax, either alone or in combination with other conditioning agents such as the above-mentioned silicone. The organic material may be a non-polymer, oligomer, or polymer. This organic material may be in the form of an oil or wax and may be added to the formulation as such 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.

[0178] 2. Emulsifying agent A variety of anionic and non-ionic emulsifying agents can be used in the hair care composition of the present invention. The anionic and non-ionic emulsifying agents can essentially be 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. Natural emulsifying agents such as lanolin, lecithin, and lignin, and derivatives thereof are also non-limiting examples of useful emulsifying agents.

[0179] 3. Chelating agent The hair care composition can further contain a chelating agent. 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 the chelating agent, the term "salts and their derivatives" 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 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, particularly all sodium, potassium or ammonium salts.

[0185] G. Foam dispenser The hair care compositions described herein can be supplied with a foam dispenser. The foam dispenser can be an aerosol foam dispenser. The aerosol foam dispenser can include a storage container for holding the hair treatment composition. The storage container can be made of any suitable material selected from the group consisting of plastic, metal, alloy, laminate, and combinations thereof. The storage container can be provided for single use only. The storage container can be removable from the aerosol foam dispenser. Alternatively, the storage container can be integrated with the aerosol foam dispenser. Further, two or more storage containers may be present.

[0186] The foam dispenser can be a mechanical foam dispenser. The described mechanical foam dispenser can be selected from the group consisting of a squeeze foam dispenser, a pump foam dispenser, other mechanical foam dispensers, and combinations thereof. The mechanical foam dispenser can be a squeeze foam dispenser. Non-limiting examples of suitable pump dispensers include those described in WO 2004 / 078903, WO 2004 / 078901, and WO 2005 / 078063, and can be supplied by Albea (60 Electric Ave., Thomaston, CT 06787 USA) or Rieke Packaging Systems (500 West Seventh St., Auburn, Indiana 46706).

[0187] A mechanical foam dispenser may include a containment vessel for holding a hair treatment composition. The containment vessel may be made of any suitable material selected from the group consisting of plastic, metal, alloy, laminate, and combinations thereof.

The containment vessel may be removable from the mechanical foam dispenser. Alternatively, the containment vessel may be integral with the mechanical foam dispenser. Further, two or more containment vessels may be present.

[0188] The containment vessel may be constructed of a material selected from the group consisting of rigid materials, flexible materials, and combinations thereof. The containment vessel may be constructed of a rigid material if it does not collapse under external atmospheric pressure when the interior is subjected to a partial vacuum.

[0189] H. Product Form The hair care composition of the present invention may be present in typical hair care formulations. The composition may be in the form of a solution, dispersion, emulsion, powder, talc, capsule, sphere, sponger, solid dosage form, foam, and other delivery mechanisms. The composition of the present invention may be in the form of leave-on hair products such as hair tonics, 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.

[0190] I. Applicator In the present invention, the hair care composition may be dispensed from an applicator for direct dispensing onto the scalp region. By direct dispensing onto the scalp via a targeted delivery applicator, it becomes possible to directly attach an undiluted cleaning agent to the locations where cleaning is particularly required. This also minimizes the risk of the cleaning solution getting into the eyes.

[0191] The applicator is attached to or can be attached to a bottle containing a cleansing hair care composition. The applicator can consist of a base that holds or extends to the 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.

[0192] Alternatively, the applicator can also consist of brush-like bristles attached to or extending from the base. In this case, the product is ejected from the base, and the bristles allow for the distribution of the product by a combing or brushing motion.

[0193] The design and material of the applicator and comb teeth can also be optimized to allow for a scalp massage. In this case, the shape of the comb teeth or bristles at the tip would be more rounded, like the roller ball applicator used for eye cream, which would be effective. The material would be smoother and softer, and it could be beneficial, for example, to have a metallic or metallic-like finish, a "rubber-like material".

[0194] Measurement of the Adhesion of the Surfactant-Soluble Agent The adhesion of the surfactant-soluble agent onto the scalp in vivo can be measured by treating the scalp with the surfactant-soluble agent containing the cleansing composition, rinsing it off, and then ethanol-extracting the soluble agent. The concentration of the agent 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 the amount collected in grams by using the concentration multiplied by the volume.

[0195] The percentage of the adhered agent can be calculated using the following equation.

[0202] Preparation of shampoo composition The shampoo 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 make a homogeneous mixture. The mixture can be heated to 50 - 75 °C to accelerate the solubilization of the solubilizing agent and then cooled. The product pH may be adjusted as necessary to provide a shampoo composition of the present invention suitable for application to human hair and scalp, and the pH may vary from about pH 4 - 9, or from about pH 4 - 6, or from about pH 4.5 - 5.5 based on the selection of a particular detergency surfactant and / or other components.

[0203] Non-limiting Examples The shampoo compositions shown in the following examples are prepared by conventional compounding and mixing methods. All amounts exemplified are listed as weight percentages on an active basis, excluding minor materials such as diluents, preservatives, coloring solutions, imaging components, plants, etc., unless otherwise specified. Unless otherwise specified, all % are based on weight.

[0207] Discussion of Results for Examples 1 - 6 Example 2 is a comparative example demonstrating that when only reducing the surfactant concentration, the adhesion efficiency only increases up to 1.3 times that of the control (Example 1). Examples 4 and 6 are comparative examples showing that when combined with a lower surfactant concentration and a cationic polymer whose molecular weight (MW) and charge density (CD) do not satisfy the formula CD + 8×10 -7* MW - 1.5 ≥ 0, the adhesion efficiency only increases up to 1.3 times that of the respective control (Examples 3 and 5).

[0213] Discussion on the Results for Examples 7 to 20 Examples 7, 10, 13, 16 and 19 are controls. The remaining examples in this set (Examples 7 to 20) contain a lower concentration of surfactant in combination with a cationic polymer whose molecular weight (MW) and charge density (CD) satisfy the formula CD + 8×10 -7* MW - 1.5 ≥ 0, and are representative compositions of the present invention showing an increased adhesion efficiency 1.4 to 2.2 times that of each control. These adhesion efficiencies are higher than those observed in Examples 2, 4 and 6 in which only the surfactant concentration was decreased or a lower surfactant concentration was combined with a cationic polymer that does not satisfy the formula CD + 8×10 -7* MW - 1.5 ≥ 0.
