DESCRIPTION

Title of the Invention

LONG CHAIN AMIDE-MODIFIED SILICONE - AMINO-MODIFIED SILICONE COPOLYMER AND USES THEREOF

Technical Field

[0001] The present invention relates to an organopolysiloxane modified by a long chain amide group having a long chain hydrocarbon site and an amino group-containing group and uses thereof; and particularly relates to a cosmetic composition, in particular a hair cosmetic composition. Priority is claimed on Japanese Patent Application No.2011-239406, filed on October 31 , 2011 , the content of which is incorporated herein by reference.

Background Art

[0002] Conventionally, many products are known as modified silicones compounded in cosmetic compositions. Examples of widely used products include silicones with a high degree of polymerization, amino-modified silicones, and the like. Additionally, an amide-modified silicone has been suggested and composition of such in a hair cosmetic composition has been proposed.

[0003] For example, Japanese Unexamined Patent Application Publication Nos. H03-206022, H05-85918, and Japanese Unexamined Patent Application Publication (Translation of PCT Application) No. 2007-505917 describe a modified organopolysiloxane that may have amide groups and also suggest that it is possible to compound such an organopolysiloxane in a hair cosmetic composition.

[0004] Additionally, Japanese Unexamined Patent Application Publication No. 2004-224729 describes a cosmetic composition comprising a wax-like organopolysiloxane, and a wax-like organopolysiloxane having an amide group, but the chain length of the portion of the silicone backbone that does not have a functional group is short.

Technical Problem

[0006] However, with the amide group that may exist on the modified organopolysiloxane described in Japanese Unexamined Patent Application Publication Nos. H03-206022,

H05-85918, and Japanese Unexamined Patent Application Publication (Translation of PCT Application) No. 2007-505917, the chain length of the alkyl group forming the amide group is short. Therefore, it is difficult to impart smoothness, luxuriousness, softness, and similar cosmetic characteristics to the hair in a well-balanced manner. Particularly, effects are insufficient from the perspective of imparting cosmetic characteristics to hair that has been damaged through bleaching or hair coloring.

[0007] Additionally, with the wax-like organopolysiloxane having the amide group described in Japanese Unexamined Patent Application Publication No. 2004-224729, while a hard film is formed on the surface of the hair, the organopolysiloxane is wax-like and also the portion of the silicone backbone that does not have a functional group is short. Therefore, it is difficult to impart smoothness and softness, and there is clearly room for improvement regarding the imparting of cosmetic characteristics.

[0008] In light of the foregoing problems with existing technologies, an object of the present invention is to provide a modified silicone by which cosmetic characteristics such as smoothness, luxuriousness, softness, and the like can be imparted to the hair in a well-balanced manner, when used as a component of a hair cosmetic composition. Particularly, an object of the present invention is to provide a modified silicone by which an appropriate degree of smoothness when applying and rinsing, post-drying smoothness, and post-drying luxuriousness can be imparted, even when applied to damaged hair.

By setting the viscosity to be not greater than 1 ,000,000 mPa^»s, the possibility of the copolymer being unevenly applied to the hair surface, thus resulting in a heavy, varying tactile sensation, can be suppressed. On the other hand, by setting the viscosity to be not less than 5 mPa^«s, the copolymer will remain on the hair and a more smooth finish can be realized.

[0043] The viscosity of the long chain amide-modified silicone · amino-modified silicone copolymer of the present invention can be measured using a commercial rotating viscometer. Examples of commercial viscometers include Brookfield viscometers (manufactured by

Brookfield Engineering, USA) and Vismetron viscometers (manufactured by Shibaura System Co., Ltd.).

[0051] A tertiary amine preferably co-exists in the amidation reaction using the long chain carboxylic acid halide (c) in order to supplement the hydrogen halide that is produced as a result of the reaction. The reaction proceeds at a low temperature, but cooling is necessary because heat is generated. Additionally, the components may be reacted, as necessary, in a solvent.

[0057] A container in which the cosmetic composition of the present invention is stored is not particularly limited, and any container such as a jar, pump, tube, bottle, pressurized can dispensing container, pressure resistant aerosol container, light-blocking container, compact container, cosmetic receptacle (kanazara), stick container, repeating container, spray container, divided container provided with a compound liquid dispensing opening, and the like can be filled with the cosmetic composition or cosmetic product. Normal silicone-based formulations tend to separate easily in tubes, but the cosmetic composition of the present invention has superior stability and the tendency to separate is suppressed. Therefore, there is a benefit that the cosmetic composition of the present invention can be stored stably, even when charged into a tube container.

[0058] The cosmetic composition (and the oil-based composition) of the present invention can be prepared appropriately by mixing the component (A) and various components that are known in the field of cosmetic compositions. A detailed description thereof is given hereinafter.

[0059] [Oil agent]

The cosmetic composition (and the oil-based composition) of the present invention preferably comprise at least one type of oil agent (B). By using the component (A) and the oil agent (B) together, feeling to touch and other characteristics can be improved. The oil agent in the present invention is not particularly limited and oil agents commonly used as components of cosmetic compositions can be used. The oil agent (B) is typically a liquid at 5 to 100°C, and preferably is a liquid at 25°C, but may be a solid such as a wax, or may be in a highly viscous gum-like or paste-like form described hereinafter. One or two or more types of the oil agent (B) can be used, depending on the purpose thereof.

[0060] The oil agent (B) is preferably dispersed in the component (A), or has compatibility therewith. An oil phase in which the component (A) and the component (B) are mixed is preferably mixed/dispersed uniformly or homogeneously. Particularly, the oil phase is preferably substantially free of gel particles. The oil agent (B) is not particularly limited and any oil agent can be used. For example, both a silicone-based oil agent (B1) and a hydrocarbon oil or similar non silicone-based oil agent (B2) can be used as the oil agent (B). However, from the perspective of affinity, the component (B) is preferably a silicone-based oil agent.

[0061] In general, silicone-based oil agents (B1) are hydrophobic, and a molecular structure thereof may be straight, cyclic, or branched. In general, the functional groups of silicone-based oil agents are methyl groups or hydroxyl groups, but the silicone-based oil agent may be an organo-modified silicone having a portion or all of said groups substituted with functional groups. This organo-modified silicone may be an organo-modified silicone other than the component (A), and is a component that is compounded in the cosmetic composition of the present invention. The backbone of the organo-modified silicone, in addition to polysiloxane bonds, may include an alkylene chain, an aminoalkylene chain, or a polyether chain; and may include a so-called "block copolymer". Additionally, the organo-modified groups may be included in a sidechain or one or both terminals of a polysiloxane chain. Specific examples thereof include amino-modified silicone, aminopolyether-modified silicone, epoxy-modified silicone, carboxyl-modified silicone, amino acid-modified silicone, acryl-modified silicone, phenol-modified silicone,

amidealkyl-modified silicone, polyamide-modified silicone, aminoglycol-modified silicone, alkoxy-modified silicone, silicone modified by higher alkyl having from 8 to 30 carbons, polyglyceryl-modified silicone, glyceryl-modified silicone, xylitol-modified silicone, sugar alcohol-modified silicone, fatty acid-modified silicone, higher alcohol-modified silicone, and alkyl-modified silicone resin.

[0062] Examples of the straight organopolysiloxane include organopolysiloxanes represented by the following general formula (5):

In this formula, R is a hydrogen atom, or a group selected from a hydroxyl group, a substituted or unsubstituted monovalent hydrocarbon group, an alkoxy group, a polyoxyalkylene group, and a polyorganosiloxane group;

f is an integer from 0 to 3; g^' is an integer from 0 to 10,000; and is an integer from 0 to 10,000; provided that 1≤g'+l'<10,000. A viscosity at 25°C of this straight organopolysiloxane is not particularly limited, and may include silicone oils having typical viscosities in a range of 0.65 to 1 ,000,000 mm²/sec and silicone gums having ultra-high viscosities.

[0063] Examples of the substituted or unsubstituted monovalent hydrocarbon group include methyl groups, ethyl groups, propyl groups, butyl groups, pentyl groups, hexyl groups, heptyl groups, octyl groups, decyl groups, dodecyl groups, and similar straight or branched chain alkyl groups having from 1 to 30 carbons; cyclopentyl groups, cyclohexyl groups, and similar cycloalkyl groups having from 3 to 30 carbons; phenyl groups, tolyl groups, xylyl groups, naphthyl groups, and similar aryl groups having from 6 to 30 carbons; and groups wherein the hydrogen atoms bonded to the carbon atoms of these groups are substituted at least partially by fluorine or a similar halogen atom, or an organic group having an epoxy group, an acyl group, a carboxyl group, an amino group, an amido group, a (meth)acryl group, a mercapto group, a carbinol group, a phenol group, or the like. Examples of the alkoxy group include methoxy groups, ethoxy groups, propoxy groups, and similar alkoxy groups having from 1 to 30 carbons.

[0064] Specific examples of the silicone oil include a dimethylpolysiloxane in which both molecular terminals are capped with trimethylsiloxy groups (from low viscosities such as 2 mPa-s, 6 mPa*s, or the like to high viscosities such as 1 ,000,000 mPa^«s and the like; and, furthermore, gum-like ultra-high viscosity dimethyl silicones), an organohydrogenpolysiloxane, a

methylphenylpolysiloxane in which both molecular terminals are capped with trimethylsiloxy groups, a copolymer of methylphenylsiloxane and dimethylsiloxane in which both molecular terminals are capped with trimethylsiloxy groups, a diphenylpolysiloxane in which both molecular terminals are capped with trimethylsiloxy groups, a copolymer of diphenylsiloxane and dimethylsiloxane in which both molecular terminals are capped with trimethylsiloxy groups, a trimethylpentaphenyltrisiloxane, a phenyl(trimethylsiloxy)siloxane, a methylalkylpolysiloxane in which both molecular terminals are capped with trimethylsiloxy groups, a copolymer of methylalkylsiloxane and dimethylpolysiloxane in which both molecular terminals are capped with trimethylsiloxy groups, a copolymer of methyl (3,3,3-trifluoropropyl) siloxane and

dimethylsiloxane in which both molecular terminals are capped with trimethylsiloxy groups, an α,ω-diethoxypolydimethylsiloxane, a high alkoxy-modified silicone, a higher fatty acid-modified silicone, a dimethiconol, a 1 ,1 ,1 ,3,5,5,5-heptamethyl-3-octyltrisiloxane, a

1 ,1 ,1 ,3,5,5,5-heptamethyl-3-dodecyltrisiloxane, a

1 ,1 ,1 ,3,5,5,5-heptamethyl-3-hexadecyltrisiloxane, a tristrimethylsiloxymethylsilane, a

tristrimethylsiloxyalkylsilane, a tetrakistrimethylsiloxysilane, a

tetramethyl-1 ,3-dihydroxydisiloxane, an octamethyl-1 ,7-dihydroxytetrasiloxane, a

hexamethyl-1 ,5-diethoxytrisiloxane, a hexamethyldisiloxane, an octamethyltrisiloxane, and similar low molecular weight products; and a dimethylpolysiloxane capped at both molecular terminals with trimethylsilyl groups, an σ,ω-dihydroxypolydimethylsiloxane; and the like.

[0065] In the cosmetic composition of the present invention, silicone gums having viscosities exceeding 1 ,000,000 mm²/s are referred to as having ultra-high viscosity, but those products that have fluidity can be suitably used as the silicone oil. Silicone gum is a straight

diorganopolysiloxane having an ultra-high degree of polymerization, and is also called silicone raw rubber or organopolysiloxane gum. Silicone rubber is differentiated from the oily silicones described above because the degree of polymerization of silicone rubber is high and, as a result, it has a degree of plasticity that is measurable. This silicone gum can be compounded as-is in the cosmetic composition of the present invention, or alternately can be compounded as a liquid gum dispersion in which an oil-like silicone is dispersed (oil dispersion of the silicone gum).

[0066] Examples of such a silicone raw rubber include substituted or unsubstituted

organopolysiloxanes having a dialkylsiloxy unit (D unit) such as a dimethylpolysiloxane, a methylphenylpolysiloxane, an aminopolysiloxane, a methylfluoroalkylpolysiloxane, or the like, or products having micro crosslinked structures thereof. Typical examples thereof include products represented by the general formula:

1⁰(CH3)2SiO{(CH3)₂SiO}_s{(CH3)R¹²SiO},Si(CH₃)2R¹⁰. In this formula, R¹² is a group selected from a vinyl group, a phenyl group, an alkyl group having from 6 to 20 carbons, an aminoalkyi group having from 3 to 15 carbons, a perfluoroalkyl group having from 3 to 15 carbons, and a quaternary ammonium salt group-containing alkyl group having from 3 to 15 carbons; the terminal group R¹⁰ is a group selected from an alkyl group having from 1 to 8 carbons, a phenyl group, a vinyl group, an aminoalkyi group having from 3 to 15 carbons, a hydroxyl group, and an alkoxy group having from 1 to 8 carbons. Additionally, s is from 2,000 to 6,000, t is from 0 to 1 ,000, and s+t= 2,000 to 6,000. Of these, a dimethylpolysiloxane raw rubber having a degree of polymerization of 3,000 to 20,000 is preferable. Additionally, an amino-modified

methylpolysiloxane raw rubber having a 3-aminopropyl group, an

N-(2-aminoethyl)3-aminopropyl group, or the like on the molecular sidechain or terminal is preferable. Furthermore, in the present invention, one or two or more types of silicone gums can be used as necessary.

[0067] Silicone gum has an ultra-high degree of polymerization and, therefore forms a protective film with superior breathability and retention on hair. Therefore, the silicone gum is a component which can particularly provide glossiness and luster to hair and can impart a texture of firmness and body to the entire hair during use and after use.

[0068] A compounded amount of the silicone gum is, for example, from 0.05 to 30 wt.% (mass%) and preferably from 1 to 15 wt.% (mass%) of the entire cosmetic composition. When the silicone gum is used as an emulsion composition prepared via a step of pre-emulsifying

(including emulsion polymerization), the silicone gum can easily be compounded, and can be stably compounded in the cosmetic composition of the present invention. An effect of imparting a specific feeling to touch or glossiness of the hair may be insufficient if the compounded amount of the silicone gum is less than the lower limit described above.

[0069] Examples of the cyclic organopolysiloxane include organopolysiloxanes represented by the following general formula (6):

In this formula, R⁹ is the same as described above;

m is an integer from 0 to 8; and

n is an integer from 0 to 8, provided that 3≤m+n<8.

[0070] Examples of the cyclic organopolysiloxane include hexamethyl cyclotrisiloxane (D3), octamethyl cyclotetrasiloxane (D4), decamethyl cyclopentasiloxane (D5),

dodecamethyl-cyclohexasiloxane (D6), 1 ,1-diethylhexamethyl cyclotetrasiloxane,

phenylheptamethyl cyclotetrasiloxane, 1 ,1-diphenylhexamethyl cyclotetrasiloxane,

1 ,3,5,7-tetravinyltetramethyl cyclotetrasiloxane, 1 ,3,5,7-tetramethyl cyclotetrasiloxane,

1 ,3,5,7-tetracyclohexyltetramethyl cyclotetrasiloxane, tris(3,3,3-trifluoropropyl)

trimethylcyclotrisiloxane, 1 ,3,5,7-tetra(3-methacryloxypropyl) tetramethyl cyclotetrasiloxane, 1 ,3,5,7-tetra(3-acryloxypropyl) tetramethyl cyclotetrasiloxane, 1 ,3,5,7-tetra(3-carboxypropyl) tetramethyl cyclotetrasiloxane, 1 ,3,5,7-tetra(3-vinyloxypropyl) tetramethyl cyclotetrasiloxane, 1 ,3,5,7-tetra(p-vinylphenyl) tetramethyl cyclotetrasiloxane, 1 ,3,5,7-tetra[3-(p-vinylphenyl) propyl] tetramethyl cyclotetrasiloxane, 1 ,3,5,7-tetra(N-acryloyl-N-methyl-3-aminopropyl) tetramethyl cyclotetrasiloxane, 1 ,3,5,7-tetra(N,N-bis (lauroyl)-3-aminopropyl) tetramethyl cyclotetrasiloxane, and the like.

[0071] Examples of the branched organopolysiloxane include organopolysiloxanes represented by the following general formula (7):

R⁹(4-p)Si(OSiCH3)q (7) In this formula, R⁹ is the same as described above;

p is an integer from 1 to 4; and

q is an integer from 0 to 500.

[0072] Examples of the branched organopolysiloxane include low molecular weight products such as methyltristrimethylsiloxysilane, ethyltristrimethylsiloxysilane,

propyltristrimethylsiloxysilane, tetrakistrimethylsiloxysilane, and phenyltristrimethylsiloxysilane. A silicone resin having a highly branched structure, a net-like structure, or a cage-like structure may be used as the branched organopolysiloxane. A silicone resin having at least a monoorganosiloxy unit (T unit) and/or a siloxy unit (Q unit) is preferable. Such silicone resins having branch units as described above have net-like structures and, therefore, form a uniform film when applied to the hair or the like and impart protective effects against drying and low temperatures. Furthermore, silicone resins that have these branch units adhere firmly to the hair or the like and can impart luster and a feeling of sheerness to the hair or the like.

[0073] Next, higher alkyl-modified silicones, alkyl-modified silicone resins, and

polyamide-modified silicone resins that are particularly preferable as the organo-modified silicone will be described. The higher alkyl-modified silicone is in the form of a wax at room temperature, and is a useful component as a portion of the base material of an oil-based solid cosmetic composition. Thus, the higher alkyl-modified silicone can be suitably used in the cosmetic composition of the present invention. Examples of the higher alkyl-modified silicone wax include methyl (long chain alkyl) polysiloxanes having both molecular terminals capped with trimethylsiloxy groups, copolymers of a dimethylpolysiioxane having . both molecular terminals capped with trimethylsiloxy groups and a methyl (long chain alkyl) siloxane, dimethylpolysiioxane modified with long chain alkyls at both terminals, and the like. Examples of commercially available products include AMS-C30 Cosmetic Wax, 2503 Cosmetic Wax, and the like

(manufactured by Dow Corning Corporation, in the USA).

[0074] The component (A) has superior dispersibility properties in the higher alkyl-modified silicone wax due to having long chain hydrocarbon groups and, thereby a cosmetic composition exhibiting superior storage stability over an extended period of time can be obtained. Additionally, the formability of the cosmetic composition is superior. In particular, in a system containing a powder, there is an advantage in that separation of the higher alkyl-modified silicone wax, for the most part, does not occur, and a cosmetic composition having superior

form-retaining strength and which spreads smoothly and uniformly when applied can be provided.

[0075] In the cosmetic composition of the present invention, the higher alkyl-modified silicone wax preferably has a melting point of not lower than 60°C because such will lead to cosmetic retainability effects and stability at high temperatures.

[0076] The alkyl-modified silicone resin is a component that imparts sebum durability, moisturizing properties, and a fine feeling to touch of the skin to the cosmetic composition; and an alkyl-modified silicone resin that is in the form of a wax at room temperature can be suitably used. Preferred examples thereof include the silsesquioxane resin wax described in Japanese Patent Application (Translation of PCT Application) No. 2007-532754. Examples of

commercially available products include SW-8005 C30 RESIN WAX (manufactured by Dow Corning Corporation, in the USA), and the like.

[0077] Like the higher alkyl-modified silicone wax, the component (A) can uniformly disperse the alkyl-modified silicone resin wax in the cosmetic composition. Furthermore, an oil phase including the alkyl-modified silicone resin wax can be stably emulsified with another arbitrary surfactant and, as a result can improve conditioning effects and the like with respect to hair, and impart a luxurious feeling to touch.

[0078] Examples of the polyamide-modified silicone include siloxane base polyamide

compounds described in U.S. Patent 5981680 (Japanese Unexamined Patent Application Publication No. 2000-038450) and Japanese Unexamined Patent Application Publication (Translation of PCT Application) No. 2001-512164. Examples of commercial products thereof include 2-8178 Gellant and 2-8179 Gellant (manufactured by Dow Corning Corporation, in the USA), and the like. This polyamide-modified silicone also functions as an oil-based raw material, specifically as a thickening/gelling agent of a silicone oil.

[0079] When the polyamide-modified silicone is used in combination with the component (A), the cosmetic composition of the present invention delivers an excellent sense of stability and adhesion, and excellent spreading and setting when applied to the hair or the like, Additionally, there are advantages from a quality standpoint such that a glossy feeling of sheerness and superior luster can be provided, the viscosity or hardness (softness) of the entire cosmetic composition containing the oil-based raw material can be appropriately adjusted, and an oily sensation (oily and sticky feeling to touch) can be totally controlled. Furthermore, by using the component (A), the dispersion stability of perfumes, powders, and the like will be improved. Therefore, the obtained cosmetic composition will be characterized by being able to maintain a uniform and fine cosmetic sensation for an extended period of time.

[0080] A higher alcohol (B2-1), a hydrocarbon oil (B2-2), a fatty acid ester oil (B2-3), a higher fatty acid (B2-4), oils and fats, and fluorine-based oil agents are exemplary as the non silicone-based oil agent (B2), but the non silicone-based oil agent (B2) is not particularly limited in the present invention, and preferably is a higher alcohol, a hydrocarbon oil, a fatty acid ester oil, or a higher fatty acid, and more preferably is a higher alcohol. These oil agents display superior compatibility and dispersibility with the component (A) and, therefore, can be stably compounded in the cosmetic composition of the present invention, and, moreover can supplement the effects of the component (A), and reinforce each unique effect thereof.

[0081] The higher alcohol (B2-1) is, for example, a higher alcohol having from 10 to 30 carbons. Said higher alcohol is a saturated or unsaturated monovalent aliphatic alcohol, and the hydrocarbon group portion thereof may be straight or branched, but is preferably straight.

Examples of the higher alcohols having from 10 to 30 carbons include lauryl alcohol, myristyl alcohol, palmityl alcohol, stearyl alcohol, behenyl alcohol, hexadecyl alcohol, oleyl alcohol, isostearyl alcohol, hexyldodecanol, octyldodecanol, cetostearyl alcohol, 2-decyltetradecinol, cholesterol, sitosterol, phytosterol, lanosterol, lanolin alcohol, hydrogenated lanolin alcohol, and the like. Note that in the present invention, it is preferable that a single higher alcohol having a melting point from 40 to 80°C is used or, alternately that a plurality of higher alcohols is combined so that a melting point thereof is from 40 to 70°C. The higher alcohols described above act with a surfactant to form an aggregate known as an "alpha gel", increase the viscosity of the formulation, and stabilize emulsions and, therefore are particularly useful as the base ingredient of a cosmetic composition. Note that of the organo-modified silicones described above as the oil agent (B), particularly, the higher alcohol-modified silicone obtained by modifying

monohydrogenheptamethyltrisiloxane with undecenyl alcohol has an aspect as a higher alcohol due to the formation of an alpha gel aggregate, in addition to the aspect as the oil agent and, therefore, can be used in combination as necessary for the purpose of obtaining improved feel and the like.

[0082] Examples of the hydrocarbon oil (B2-2) include liquid paraffin, light liquid isoparaffin, heavy liquid isoparaffin, petrolatum, n-paraffin, isoparaffin, isododecane, isohexadecane, polyisobutylene, hydrogenated polyisobutylene, polybutene, ozokerite, ceresin, microcrystalline wax, paraffin wax, polyethylene wax, polyethylene/polypropylene wax, squalane, squalene, pristane, polyisoprene, and the like.

[0083] Examples of the fatty acid ester oil (B2-3) include hexyldecyl octanoate, cetyl octanoate, isopropyl myristate, isopropyl palmitate, butyl stearate, hexyl laurate, myristyl myristate, oleyl oleate, decyl oleate, octyldodecyl myristate, hexyldecyl dimethyloctanoate, cetyl lactate, myristyl lactate, diethyl phthalate, dibutyl phthalate, lanolin acetate, ethylene glycol monostearate, propylene glycol monostearate, propylene glycol dioleate, glyceryl monostearate, glyceryl monooleate, glyceryl tri-2-et ylhexanoate, trimethylolpropane tri-2-ethylhexanoate, ditrimethylolpropane triet ylhexanoate, ditrimethylolpropane (isostearate/sebacate),

2-butyl-2-ethyl-1 ,3-propanediol dioctanoate, pentaerythrityl tetraoctanoate, pentaerythrityl hydrogenated rosin, pentaerythrityl triethylhexanoate, dipentaerythrityl

(hydroxystearate/stearate/rosinate), polyglyceryl tetraisostearate, polyglyceryl-10

nonaisostearate, polyglyceryl-8 deca(erucate/isostearate/ricinoleate), (hexyldecanoic

acid/sebacic acid) diglyceryl oligoester, glycol distearate (ethylene glycol distearate), diisopropyl dimer dilinoleate, diisostearyl dimer dilinoleate, di(isostearyl/phytosteryl) dimer dilinoleate, (phytosteryl/behenyl) dimer dilinoleate, (phytosteryl/isostearyl/cetyl/stearyl/behenyl) dimer dilinoleate, dimer dilinoleyl dimer dilinoleate, dimer dilinoleyl diisostearate, dimer dilinoleyl hydrogenated rosin condensate, dimer dilinoleic acid hardened castor oil, hydroxyalkyl dimer dilinoleyl ether, glyceryl triisooctanoatei glyceryl triisostearate, glyceryl trimyristate, glyceryl triisopalmitate, glyceryl trioctanoate, glyceryl trioleate, glyceryl diisostearate, glyceryl

tri(caprylate/caprate), glyceryl tri(caprylate/caprate/myristate/stearate), hydrogenated rosin triglyceride (hydrogenated ester gum), rosin triglyceride (ester gum), glyceryl behenate eicosane dioate, glyceryl di-2-heptylundecanoate, diglyceryl myristate isostearate, cholesteryl acetate, cholesteryl nonanoate, cholesteryl stearate, cholesteryl isostearate, cholesteryl oleate, cholesteryl 12-hydroxystearate, cholesteryl ester of macadamia nut oil fatty acid, phytosteryl ester of macadamia nut oil fatty acid, phytosteryl isostearate, cholesteryl ester of soft lanolin fatty acid, cholesteryl ester of hard lanolin fatty acid, cholesteryl ester of long-chain branched fatty acid, cholesteryl ester of long-chain a-hydroxy fatty acid, octyldodecyl ricinoleate, octyldodecyl ester of lanolin fatty acid, octyldodecyl erucate, isostearic acid hardened castor oil, ethyl ester of avocado fatty acid, isopropyl ester of lanolin fatty acid, and the like. Lanolin and lanolin derivatives can also be used as the fatty acid ester oil.

[0084] Examples of higher fatty acid (B2-4) include lauric acid, myristic acid, palmitic acid, stearic acid, behenic acid, undecylenic acid, oleic acid, linolic acid, linolenic acid, arachidonic acid, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), isostearic acid, 12-hydroxystearic acid, and the like.

[0085] A combination of a silicone-based oil agent and a non silicone-based oil agent may be used as the oil agent (B). By using both the silicone-based oil agent and the non silicone-based oil agent, in addition to the dry feeling to touch unique to silicone oils, moisture will be retained and a moisturizing feel whereby the skin or hair feels moisturized (also referred to as a luxurious feeling to touch) and smooth feeling to touch can be imparted to the cosmetic composition of the present invention. Moreover, there is a benefit in that stability over time of the cosmetic composition will not be negatively affected. Furthermore, with a cosmetic composition comprising the hydrocarbon oil and/or fatty acid ester oil and the silicone oil, these moisturizing components (the hydrocarbon oil and/or the fatty acid ester oil) can be applied on the skin or hair in a more stable and uniform manner. Therefore, the moisturizing effects of the moisturizing components on the skin are improved. Thus, compared to a cosmetic composition comprising only a non silicone-based oil agent (e.g. a hydrocarbon oil, a fatty acid ester oil, or the like), the cosmetic composition comprising a non silicone-based oil agent along with a silicone-based oil agent is advantageous in that a smoother, more luxurious feeling to touch is imparted.

[0086] In the present invention, in addition to the oil agents described above, oils and fats, higher fatty acids, fluorine-based oils, and the like may be used as the oil agent (B), and a combination of two or more types of these may be used. Particularly, oils and fats derived from plants can be suitably used in the cosmetic composition of the present invention because such oils and fats provide a healthy, natural image and are superior in terms of moisturizing, conformability to the hair, and the like.

[0087] Examples of natural animal or vegetable oils and fats and semi-synthetic oils and fats included as the oils and fats include avocado oil, linseed oil, almond oil, ibota wax, perilla oil, olive oil, cacao butter, kapok wax, kaya oil, carnauba wax, liver oil, candelilla wax, beef tallow, hydrogenated beef tallow, apricot kernel oil, spermaceti wax, hydrogenated oil, wheat germ oil, sesame oil, rice germ oil, rice bran oil, sugar cane wax, sasanqua oil, safflower oil, shea butter, Chinese tung oil, cinnamon oil, jojoba wax, olive squalane, shellac wax, turtle oil, soybean oil, tea seed oil, camellia oil, evening primrose oil, corn oil, lard, rapeseed oil, Japanese tung oil, rice bran wax, germ oil, horse fat, persic oil, palm oil, palm kernel oil, castor oil, hydrogenated castor oil, castor oil fatty acid methyl ester, sunflower oil, grape oil, bayberry wax, jojoba oil, hydrogenated jojoba ester, macadamia nut oil, beeswax, mink oil, cottonseed oil, cotton wax, Japanese wax, Japanese wax kernel oil, montan wax, coconut oil, hydrogenated coconut oil, tri-coconut oil fatty acid glyceride, mutton tallow, peanut oil, lanolin, liquid lanolin, reduced lanolin, lanolin alcohol, hard lanolin, lanolin acetate, lanolin fatty acid isopropyl ester, POE lanolin alcohol ether, POE lanolin alcohol acetate, lanolin fatty acid polyethylene glycol, POE hydrogenated lanolin alcohol ether, POE cholesterol ether, monostearyl glycerin ether (batyl alcohol ), monooleyl glyceryl ether (selachyl alcohol), egg yolk oil, and the like. Herein, "POE" means "polyoxyethylene".

[0088] Examples of the fluorine-based oil include perfluoropolyether, perfluorodecalin, perfluorooctane, and the like.

[0089] A compounded amount of the oil agent (B) in the cosmetic composition of the present invention is not particularly limited, but is preferably in a range from 0.1 to 90 wt.% (mass%), more preferably in a range from 0.5 to 70 wt.% (mass%), even more preferably in a range from 1 to 50 wt.% (mass%), and yet even more preferably in a range from 5 to 25 wt.% (mass%).

[0090] Additionally, a compounding ratio (weight ratio of (B)/(A)) of the oil agent (B) to the component (A) in the cosmetic composition (and the oil-based composition) of the present invention is preferably in a range from 0.01 to 100, and more preferably in a range from 0.1 to 50. This is because if the compounded amount of the component (B) is excessive, the effects of the component (A) will decline.

[0091] The cosmetic composition of the present invention preferably comprises at least one type of surfactant (C). The surfactant (C) is not particularly limited, and at least one type can be selected from the group consisting of anionic surfactants (C1), cationic surfactants (C2), nonionic surfactants (C3), amphoteric surfactants (C4), and semipolar surfactants (C5).

[0092] Examples of the anionic surfactants (C1) include saturated or unsaturated fatty acid salts (e.g. sodium laurate, sodium stearate, sodium oleate, sodium linolenate, and the like);

If the compounded amount of the water-soluble polymer (E) exceeds the upper limit described above, depending on the type of cosmetic composition, the hair or the like may be left with a coarse feeling to touch; and if less than the lower limit described above, advantageous technical effects such as the thickening effect, the conditioning effect, and the like may not be sufficiently realized.

[0107] [Thickening agent/gelling agent]

A ratio in the entire cosmetic composition is preferably from 0.01 to 30 wt.% (mass%),more preferably from 0.1 to 20 wt.% (mass%), and even more preferably from 1 to 10 wt.% (mass%).

[0111] By thickening or gelling the oil agent in a cosmetic composition of the present invention, it is possible to obtain an appropriate viscosity and hardness for a cosmetic composition and improve the appearance, compounding properties and sensation during use thereof, and it is also possible to obtain a desired dosage form or cosmetic composition type. An example thereof is a cosmetic composition agent in a paste-like or gel-like form. When the thickening agent/gelling agent (F) is used, quality benefits are realized such as the overall oiliness (the oily, sticky feeling to touch) can be further suppressed, and retainability can be further improved.

Compared to a silicone resin powder consisting of T units and Q units, the silicone elastomer powder is soft, has elasticity, and has superior oil absorbency. Therefore, oils and fats on the skin can be absorbed and makeup smearing can be prevented.

[0118] The silicone elastomer powder can be in various forms such as spherical, flat, amorphous, or the like. The silicone elastomer powder may also be in the form of an oil dispersion. With the cosmetic composition of the present invention, the silicone elastomer powder is particulate in form, and the primary particle size observed using an electron microscope and/or the average primary particle size measured by laser analysis or scattering is in a range from 0.1 to 50 μηι.

[0123] The solid silicone resin (H) is an organopolysiloxane having a highly branched structure, a net-like structure, or a cage structure, and is solid at room temperature. Any type of product may be used, provided that it is a silicone resin that is commonly used in cosmetic compositions and does not oppose the object of the present invention. The solid silicone resin may be a spherical powder, a flaky powder, a needle like powder, a plate-like flaky powder (including plate-like powders having appearances and particle aspect ratios commonly identified with plate-like forms), or a similar particulate. Particularly, a silicone resin powder having monoorganosiloxy units (T units) and/or siloxy units (Q units), described below, can be preferably used.

[0124] Compounding the component (A) along with the solid silicone resin (H) is useful because compatibility with the oil agent (B) and uniform dispersibility are improved, and improvement effects in sensation during use can be obtained, namely uniform adhesion to the applied area due to the compounding of the solid silicone resin (H).

[0125] Examples of the solid silicone resin (H) include MQ resins, MDQ resins, MTQ resins, MDTQ resins, TD resins, TQ resins, and TDQ resins consisting of arbitrary combinations of triorganosiloxy units (M units) (where the organo groups are only methyl groups, or are methyl groups and vinyl groups or phenyl groups), diorganosiloxy units (D units) (where the organo groups are only methyl groups, or are methyl groups and vinyl groups or phenyl groups), monoorganosiloxy units (T units) (where the organo groups are methyl groups, vinyl groups, or phenyl groups), and siloxy units (Q units). Furthermore, other examples include

trimethylsiloxysilicate, polyalkylsiloxysilicate, dimethylsiloxy unit-containing trimethylsiloxysilicate, and alkyl(perfluoroalkyl)siloxysilicate. These silicone resins are preferably oil soluble and can be dissolved in volatile silicone.

[0126] Particularly, a phenyl silicone resin having a high refractive index and a high content of phenyl groups (e.g. 217 Flake resin and the like, manufactured by Dow Corning Toray Co., Ltd.) can be easily used as a flaky silicone resin powder and, when compounded in a hair cosmetic composition, can impart a radiant feeling of sheerness of the hair.

[0127] The organopolysiloxane chain of the crosslinking organopolysiloxane (H) preferably has a three-dimensionally crosslinked structure, obtained by reacting a polyether unit and a

crosslinking component or the like consisting of an alkylene unit having from 4 to 20 carbons or an organopolysiloxane unit.

[0128] Specifically, the crosslinking organopolysiloxane (H) can be obtained via an addition reaction of an organohydrogenpolysiloxane having a silicon-bonded hydrogen atom, a polyether compound having unsaturated bonds at both terminals of the molecular chain, an unsaturated hydrocarbon having more than one double bond in the molecule, and an organopolysiloxane having more than one double bond in the molecule. Here, the crosslinking organopolysiloxane may have or may be free of unreacted silicon-bonded hydrogen atoms, phenyl groups, and similar aromatic hydrocarbon groups; octyl groups and similar long chain alkyl groups having from 6 to 30 carbons; polyether groups, carboxyl groups, the silylalkyl group having the carbosiloxane dendrimer structure described above; and similar modifying functional groups. In other words, any crosslinking organopolysiloxane can be used without limitations to physical modes or preparation methods such as dilution, properties, and the like.

[0129] As an example, the crosslinking organopolysiloxane can be obtained via an addition reaction of crosslinking components selected from an organohydrogenpolysiloxane consisting of a structural unit selected from the group consisting of an Si0₂ unit, an HSi0 ₅ unit, a R SiOi.₅ unit, a R^bHSiO unit, a R^b ₂SiO unit, a R^b ₃SiO_{0 5} unit, and a R^b ₂HSiO₀.₅ unit (where R^b is a substituted or unsubstituted monovalent hydrocarbon group having from 1 to 30 carbons, with the exception of aliphatic unsaturated groups; and a portion of R^b is a monovalent hydrocarbon group having from 8 to 30 carbons), the organohydrogenpolysiloxane having an average of 1.5 or more silicon-bonded hydrogen atoms in the molecule; a polyoxyalkylene compound having unsaturated hydrocarbon groups at both molecular terminals; a polyglycerine compound, a polyglycidylether compound, or simillar polyether compound; an α,ω-diene unsaturated hydrocarbon represented by the general formula: CH₂=CH-C_rH2r-CH=CH₂ (where r is an integer from 0 to 26); and an organopolysiloxane consisting of a structural unit selected from the group consisting of an Si0₂ unit, a (CH₂=CH)Si0_{1 5} unit, a R^cSiOi.₅ unit, a R^c(CH₂=CH)SiO unit, a R^c ₂SiO unit, a R^c ₃SiO_{0 5} unit, and a R^c ₂(CH₂=CH)SiO_{0 5} unit (where R^c is a substituted or unsubstituted monovalent hydrocarbon group having from 1 to 30 carbons, with the exception of aliphatic unsaturated groups), the organopolysiloxane having an average of 1.5 or more silicon-bonded vinyl groups in the molecule. Note that by addition reacting the unreacted silicon-bonded hydrogen atoms, the modifying functional groups described above can be introduced. For example, by reacting 1-hexene with a crosslinking organopolysiloxane having unreacted silicon-bonded hydrogen atoms, hexyl groups (C6 alkyl groups) are introduced.

[0130] Any crosslinking organopolysiloxane can be used without limitations to physical modes or preparation methods such as dilution, properties, and the like, provided that it is a crosslinking organopolysiloxane. Particularly preferable examples include α,ω-diene crosslinking silicone elastomers (commercially available products include DC 9040 Silicone Elastomer Blend, DC 9041 Silicone Elastomer Blend, DC 9045 Silicone Elastomer Blend, and DC 9046 Silicone Elastomer Blend, manufactured by Dow Corning Corporation, in the USA) described in US Patent No. 5,654,362. Likewise, examples of partial crosslinking organopolysiloxane polymers include by International Nomenclature Cosmetic Ingredient (INCI) labeling names,

(dimethicone/vinyldimethicone) crosspolymers, (dimethicone/phenylvinyldimethicone) crosspolymers, (PEG-8 to 30/C6 to C30 alkyldimethicone) crosspolymers, (vinyldimethicone/C6 to C30 alkyldimethicone) crosspolymers, (dimethicone/polyglycerine) crosspolymers, and the like.

[0131] In the case of an emulsifiable crosslinking organopolysiloxane formed by crosslinking by means of a polyether compound being compounded as a component in a cosmetic composition, the component (A) will function as a dispersing agent. In this case, there is an advantage in that a uniform emulsification system can be formed.

[0132] On the other hand, in the case of a non-emulsifiable crosslinking organopolysiloxane, formed by crosslinking by means of an unsaturated hydrocarbon group such as a diene or an organopolysiloxane being compounded as a component in a hair cosmetic composition, feel of adhesion to the hair can be improved. Furthermore, there are advantages in that excellent compatibility with other oil agents can be obtained, and the entire oil system can be uniformly and stably compounded in the hair cosmetic composition.

[0133] One or two or more types of the solid silicone resin or crosslinking organopolysiloxane (H) can be compounded depending on the purpose thereof. A compounded amount thereof is preferably in a range from 0.05 to 25 wt.% (mass%) and more preferably in a range from 0.1 to 15 wt.% (mass%) of the entire cosmetic composition, depending on purpose and compounding intention.

[0134] [Acryl silicone dendrimer copolymer]

The cosmetic composition of the present invention may further comprise an acryl silicone dendrimer copolymer (I). The acryl silicone dendrimer copolymer (I) is a vinyl polymer having a carbosiloxane dendrimer structure on the sidechain, and preferable examples thereof include the vinyl polymer described in Japanese Patent No. 4009382 (Japanese Unexamined Patent Application Publication No. 2000-063225). Examples of commercially available products include FA 4001 CM Silicone Acrylate and FA 4002 ID Silicone Acrylate (manufactured by Dow Corning Toray Co., Ltd.), and the like. However, the acryl silicone dendrimer copolymer (I) may also be an acryl silicone dendrimer copolymer having a long chain alkyl group having from 8 to 30 and preferably from 14 to 22 carbons on the sidechain or the like. When compounding the acryl silicone dendrimer copolymer alone, superior film formability can be obtained. Therefore, by compounding the acryl silicone dendrimer copolymer (I) in the cosmetic composition of the present invention, a strong coating film can be formed on the applied part, and cosmetic durability such as sebum resistance, rubbing resistance, and the like can be significantly improved.

[0135] By using the component (A) together with the acryl silicone dendrimer copolymer (I), there are advantages in that a surface protective property such as sebum resistance can be improved due to strong water repellency provided by the carbosiloxane dendrimer structure, and irregularities such as pores can be effectively concealed. Additionally, the component (A) causes the acryl silicone dendrimer copolymer (I) to blend well with the other oil agents and, therefore, there is an advantage in that degradation of the hair over a long period of time can be suppressed.

[0136] A compounded amount of the acryl silicone dendrimer copolymer (I) can be suitably selected based on the purpose and compounding intent thereof, but is preferably in a range from 1 to 99 wt.% (mass%) and more preferably in a range from 30 to 70 wt.% (mass%) of the entire cosmetic composition.

[0137] [Ultraviolet light blocking component]

The cosmetic composition of the present invention can further comprise an ultraviolet light blocking component (J). The ultraviolet light blocking component (J) preferably is hydrophobic, having absolutely no solubility in water at room temperature, or a solubility of less than 1 wt.% (mass%) per 100 g of water. The ultraviolet light blocking component (J) is a component that blocks or scatters ultraviolet light, and can be an inorganic ultraviolet light blocking component or an organic ultraviolet light blocking component. In cases where the cosmetic composition of the present invention needs to have sunblocking effects, preferably at least one type of inorganic or organic, and particularly preferably at least one type of organic ultraviolet light blocking component is compounded.

[0138] The inorganic ultraviolet light blocking component may be compounded as an ultraviolet light scattering agent such as the inorganic pigment powders and metal powder pigments mentioned above. Examples thereof include metal oxides such as titanium oxide, zinc oxide, cerium oxide, titanium suboxide, iron-doped titanium oxides, and the like; metal hydroxides such as iron hydroxides and the like; metal flakes such as platy iron oxide, aluminum flake, and the like; and ceramics such as silicon carbide, and the like. Of these, at least one type of a material selected from fine particulate metal oxides and fine particulate metal hydroxides with an average particle size in a range from 1 to 100 nm and a particulate, plate-like, needle-like, or fiber form is preferable. The powder is preferably subjected to, for example, a conventional surface treatment such as fluorine compound treatments, of which a perfluoroalkyl phosphate treatment, a perfluoroalkylsilane treatment, a perfluoropolyether treatment, a fluorosilicone treatment, or a fluorinated silicone resin treatment is preferable; silicone treatments, of which a

methylhydrogenpolysiloxane treatment, a dimethylpolysiloxane treatment, or a vapor-phase tetramethyltetrahydrogen cyclotetrasiloxane treatment is preferable; silicone resin treatments, of which a trimethylsiloxysilicic acid treatment is preferable; pendant treatments which are methods of adding alkyl chains after a vapor-phase silicone treatment; silane coupling agent treatments; titanium coupling agent treatments; silane treatments, of which a treatment by an

organopolysiloxane modified at one terminal by a trialkoxy group, an alkylsilane treatment, or an alkylsilazane treatment is preferable; oil agent treatments; N-acylated lysine treatments;

polyacrylic acid treatments; metallic soap treatments in which a stearic acid salt or a myristic acid salt is preferably used; acrylic resin treatments; metal oxide treatments; MiBrid treatments in which double coating by a liquid surface treatment agent and a soild surface treatment agent is performed; and the like. Multiple treatments described above are preferably performed. For example, the surface of the fine particulate titanium oxide can be coated with a metal oxide such as silicon oxide and alumina, and, thereafter, surface treating using an alkylsilane can be carried out. A total amount of the surface treatment agent is preferably in a range from 0.1 to 50 wt.% (mass%) of the powder.

[0139] -6-(4-methoxyphenyl)-1 ,3,5-triazine (INCI: bis-ethylhexyloxyphenol methoxyphenyl triazine, trade designation: Tinosorb® S), and the like;

2-cyano-3,3-diphenylprop-2-enoate-2-ethylhexyl ester (INCI: octocrylene); and the like. [0140] Additionally, it is possible to use a product in which the organic ultraviolet light blocking component is comprised in a hydrophobic polymer powder. The polymer powder may be hollow, and preferably has an average primary particle size in a range from 0.1 to 50 m. Particle size distribution may be broad or sharp. Types of polymer include acrylic resins, methacrylic resins, styrene resins, polyurethane resins, polyethylene, polypropylene, polyethylene terephthalate, silicone resins, nylons, acrylamide resins, and silylated polypeptide resins. A polymer powder comprising from 0.1 to 30 wt.% (mass%) of an organic ultraviolet light blocking component is preferable, and a polymer powder comprising 4-tert-butyl-4'-methoxydibenzoylmethane, which is a UV-A absorber, is particularly preferable.

[0141] In the cosmetic composition of the present invention, the ultraviolet light blocking component (J) that can be preferably used is at least one selected from the group consisting of fine particulate titanium oxide, fine particle zinc oxide, paramethoxy cinnamic acid 2-ethylhexyl, 4-tert-butyl-4'-methoxydibenzoylmethane, a benzotriazole-based UV absorber, and a

triazine-based UV absorber. These ultraviolet light blocking components (J) are generally used, are easy to acquire, and have high ultraviolet light blocking effects and, thus can be beneficially used. In particular, using both inorganic and organic ultraviolet light blocking components is preferable, and using a UV-A blocking component in combination with a UV-B blocking component is more preferable.

[0142] In the cosmetic composition of the present invention, by using the component (A) and the ultraviolet light blocking component (J) together, the ultraviolet light blocking component (J) can be stably dispersed in the cosmetic composition and the feeling to touch and the storage stability of the entire cosmetic composition can be improved. Therefore, superior UV blocking capacity can be imparted to the cosmetic composition.

[0143] In the cosmetic composition of the present invention, a total compounded amount of the ultraviolet light blocking component (J) with respect to the entire cosmetic composition is in a range from 0.1 to 40.0 wt.% (mass%), and more preferably in a range from 0.5 to 15.0 wt.% (mass%).

[0144] [Oxidation dye]

When the cosmetic composition of the present invention is used as an oxidation hair colorant, the cosmetic composition of the present invention can comprise an oxidation dye (K). Products commonly used in oxidation hair colorants, such as oxidative dye precursors, and couplers, can be used as the oxidation dye (K). Examples of oxidative dye precursors include

phenylenediamines, aminophenols, diaminopyridines, and salts thereof such as hydrochloric acid salts, sulfuric acid salts, and the like. Specific examples include phenylenediamines such as p-phenylenediamine, toluene-2,5-diamine, toluene-3,4-diamine, 2,5-diaminoanisole,

Other examples that can be arbitrarily used include those products listed in "Japanese Standards of Quasi-drug Ingredients" (published June 1991 by Yakuji Nippo Limited). Additionally, of the oxidative dye precursors and the couplers described above, one type may be used alone or a combination of two or more types may be used. At the least, an oxidative dye precursor is preferably used. Note that, from the perspectives of hair coloring properties and safety such as skin irritation and the like, a compounded amount of the oxidation dye in the composition is preferably about 0.01 to 10 wt.%.

[0145] When the cosmetic composition of the present invention is used as a two part oxidation hair colorant, a first agent includes an alkalizing agent and the oxidation dye (K) (and preferably also the coupler), and a second agent includes an oxidizing agent.

One or more of the direct dyes (L) can be used and, while a compounded amount thereof in the cosmetic composition of the present invention is not particularly limited, the compounded amount is preferably from 0.005 to 5 wt.% (mass%) and more preferably from 0.01 to 2 wt.% (mass%) of the entire weight (mass) of the composition.

[0148] When the cosmetic composition of the present invention is used as a permanent setting agent, the cosmetic composition of the present invention can comprise the reducing agent and the oxidizing agent described above. When the cosmetic composition of the present invention is used as a two part permanent setting agent, for example, a first agent includes the reducing agent (and preferably an alkalizing agent), and a second agent includes the oxidizing agent.

First, the first agent is used to dissociate the disulfide linkage of the hair and, thereafter, the hair is arranged in the desired style. Then, the second agent is used to regenerate the disulfide linkage of the hair and fix the hair style.

[0149] [Other components]

The following other components generally used in cosmetic compositions may be added to the cosmetic composition of the present invention, provided that such components do not inhibit the effectiveness of the present invention: organic resins, moisturizing agents, preservatives, antimicrobial agents, perfumes, salts, oxidizers or antioxidants, pH adjusting agents, chelating agents, refreshing agents, anti-inflammatory agents, bioactive components (skin-lightening agents, cell activating agents, agents for ameliorating skin roughness, circulation promoters, astringents, antiseborrheic agents, and the like), vitamins, amino acids, nucleic acids, hormones, clathrates, natural vegetable extract components, seaweed extract components, herbal medicine components, water, volatile solvents, and the like. However, the other components are not limited to the above. One of the other components may be used alone or an appropriate combination of two or more of the other components may be used. More specifically, these components correspond with the components recited in paragraphs 0100 to 0116 of Japanese Unexamined Patent Application Publication No. 2011-149017. Additionally, it goes without saying that cosmetic composition components and medicament components other than those recited above can be compounded in the cosmetic composition of the present invention.

[0150] The cosmetic composition (and the emulsion composition) of the present invention may comprise water. Thus, the cosmetic composition of the present invention may take the form of an oil-in-water emulsion, a water-in-oil emulsion, or a similar emulsion. In this case, the cosmetic composition of the present invention displays superior emulsion stability and sensation during use.

[0151] Water is free of ingredients that are harmful to the human body and needs only be clean. Examples thereof include tap water, purified water, mineral water, and the like. Additionally, in the cosmetic composition, particularly a cosmetic composition having the form of an emulsion, of the present invention, a compounded amount of the water is preferably from 2 to 98 wt.%

(mass%) of the cosmetic composition.

[0152] The cosmetic composition of the present invention, depending on the form and purpose thereof, may include light isoparaffin, ethers, LPG, N-methylpyrrolidone, next-generation chlorofluorocarbons, and similar volatile solvents, in addition to the water.

[0153] The component (A) may be compounded in the cosmetic composition as-is, or may be emulsified beforehand using the water and the surfactant component (C) and compounded as an emulsion. Additionally, in addition to the component (A), the oil agent component (B), or a portion thereof, may be emulsified using the water and the surfactant component (C), and compounded as an emulsion. It is necessary that the form of the emulsion correspond to the form of the cosmetic composition in which it will be compounded. For example, when the cosmetic composition is an oil-in-water emulsion such as a cleansing cosmetic composition, the emulsion can be compounded as-is by preparing it as an oil-in-water emulsion. In this case, in order to maintain the stability of the formulating system, the surfactant component (C) used in the preparation of the emulsion of the component (A) is preferably selected appropriately. Multiple surfactant components (C) may be combined. For example, surfactants with different properties such as an ionic surfactant and a nonionic surfactant, or the like, can be combined for the purpose of ensuring the stability of the emulsion.

[0154] The form of the emulsion is not limited to oil-in-water emulsions and water-in-oil emulsions, and may be a multi-layer emulsion or a micro-emulsion. Note that the form of the emulsion (oil-in-water or water-in-oil) and the particle diameter of the emulsion can be appropriately selected and adjusted depending on the type of cosmetic composition desired.

When the cosmetic composition of the present invention is an oil-in-water emulsion, a dispersion phase of the cosmetic composition is a particulate phase in which the component (A) or the component (A) and the oil agent (B) are emulsified using the surfactant component (C). The average diameter of the particles can be measured using a known measurement device employing a laser diffraction/scattering method or the like. The oil-in-water emulsion cosmetic composition may be a transparent micro-emulsion in which the measured average diameter of the dispersion phase is not more than 0.1 μηη, or may be a large particulate white turbid emulsion in which the average diameter is more than 4 μπν Furthermore, the emulsion particles may be micronized for the purpose of improving the stability and transparency of the appearance of the emulsion. An emulsion having a particle diameter from 0.5 to 20 μπι can be selected, and is particularly preferable for the purpose of improving sensation during use and adhesion characteristics to hair and skin. For example, when a micro-emulsion is used, stability will improve and, when the cosmetic compound is a cleansing cosmetic composition, lathering characteristics will improve. When the general particle diameter is from submicron to 4 μιη, general use characteristics will be superior, the balance between formulating benefits and stability will be excellent, and preparation will be easy. Additionally, when the particle diameter is large, that is, a few microns or more (e.g. from 4 to 5 μιη), improvements in sensation during use and adhesion to hair can be expected.

[0155] The cosmetic composition (and the emulsion composition) of the present invention having the form of an oil-in-water emulsion or a water-in-oil emulsion can be produced by blending the components of the cosmetic composition by means of mechanical forces using an apparatus such as a homomixer, a paddle mixer, a Henschel mixer, a homo-disper, a colloid mill, a propeller stirrer, a homogenizer, an in-line continuous emulsifier, an ultrasonic emulsifier, or a vacuum kneader, or the like.

[0156] The cosmetic composition of the present invention that is in the form of an emulsion essentially includes the component (A), and the dispersion phase thereof has superior dispersion stability. Thus, the cosmetic composition of the present invention has excellent stability over time, a uniform appearance, and superior sensation during use.

[0157] The cosmetic composition of the present invention can be advantageously used as a hair cosmetic composition.

[0158] Uses of the hair cosmetic composition of the present invention include all uses as a cosmetic composition to be applied to hair and, as described above, can be particularly advantageously used as a hair cleansing cosmetic composition, a hair conditioning cosmetic composition, a hair styling cosmetic composition, and a hair coloring cosmetic composition. [0159] Hair cleansing cosmetic compositions are cleansing agents used for the purpose of cleaning the hair or the scalp and the features thereof are diverse. In addition to the fundamental feature of cleansing, hair cleansing cosmetic compositions may have conditioning effects, dandruff prevention effects, and other secondary features. Specific examples of hair cleansing cosmetic compositions include shampoos, conditioning shampoos, dandruff shampoos, and the like.

[0160] Hair conditioning cosmetic compositions are hair cosmetic compositions that have features such as concealing and repairing hair damage, protecting damaged hair itself, and preventing damage to the hair. Hair conditioning cosmetic compositions may be used immediately following hair cleansing, or after drying the hair. Specific examples of hair conditioning cosmetic compositions include rinses, rinse-in shampoos, hair conditioners, hair creams, hair treatments, and the like.

[0161] Hair styling cosmetic compositions are cosmetic compositions used for the purpose of finishing hair and are divided into two main categories of those focused on the immobilization and hair dressing/setting of the hair, and those focused on improving the luster, feeling to touch, texture, workability, and the like of the hair. Due to progression in imparting multiple features and advanced features to cosmetic compositions, there are also cosmetic compositions that have the features of both categories and, in some cases, functionally overlap with the hair conditioning cosmetic compositions described above. Specific examples of the hair styling cosmetic compositions include hair foams, hair sprays, hair styling lotions, hair gels, hair liquids, hair oils, hair waxes, hair blows, and the like. More specific examples include hair mists, super hard mousses, super hard gels, super hard sprays, hard mousses, hard gels, hard sprays, soft sprays, soft mousses, soft gels, blowing lotions, straightening lotions, straightening mousses, waters, pomades, hair liquids, wet gels, hair waxes, hair creams, hair milks, wavy mousses, styling essences, and the like.

[0162] Hair coloring cosmetic compositions act either physically or chemically on the surface of the hair to temporarily, semi-permanently, or permanently color the hair. Examples thereof include coloring sprays, coloring sticks, hair manicures, coloring lotions, glossy sprays, manicuring sprays, and the like.

[0163] The hair cosmetic composition of the present invention can optionally comprise any combination of all of the components, provided that the component (A) is comprised. In other words, the hair cosmetic composition of the present invention can comprise any combination of the components (B) to (M) below along with the component (A).

[0164] (B) Oil agent

(C) Surfactant

(D) Alcohol

(E) Water-soluble polymer (F) Thickening agent/gelling agent

Note that the hair cosmetic composition of the present invention generally comprises water.

[0166] Hereinafter, examples will be used to describe general, preferable combinations of the components and compounding purposes thereof, for various types and uses of cosmetic composition to be applied to the hair. However, the hair cosmetic composition according to the present invention shall not be construed to be limited to the configurations given by way of example below.

[0167] Of the hair cosmetic compositions of the present invention, a hair cleansing cosmetic composition comprises the following as exemplary compounding components: the component (A), the oil agent (B) as a conditioning agent, the water-soluble polymer (E) also as a

conditioning agent, the surfactant (C) as a foaming/cleansing base agent, the alcohol (D) as a moisturizing/stabilizing agent, and also water, a pH adjusting agent, a preservative, and similar other components (M). From the perspective of cleansing effects and the like, of the component (C), generally it is preferable that the anionic surfactant (C1) is used, and it is more preferable that a combination of the anionic surfactant (C1 ) and one or more of the nonionic surfactant (C3) and the amphoteric surfactant (C4) is used. Additionally, one or two or more types selected from a dimethylpolysiloxane, an amino-modified silicone, and similar

organo-modified silicones, an ester oil, a lanolin derivative, and a higher alcohol can be used preferably as the oil agent (B). Particularly, from the perspective of the conditioning effects imparted to the hair, the amino-modified silicone is preferably selected, and the amino equivalent weight and the like of the modified silicone can be designed as deemed appropriate. Likewise, of the components (E), the cationic water-soluble polymer (E1) is preferably selected from the perspective of conditioning effects. Particularly, a combination of the component (A), the anionic surfactant (C1), and the cationic water-soluble polymer (E1) is advantageous because latherability and the feel of the lather will be superior, cleansing characteristics will be superior, and when the hair is wet after cleansing and when the hair is dry, smooth passability of the fingers through the hair, without a feeling of sticking/squeaking, can be imparted. Additionally, for the purpose of imparting smooth passability of the fingers through the hair, a polyether-modified silicone, a straight chain block ABn-type polyether-modified silicone, a straight chain block ABn-type amino polyether-modified silicone, or similar polyether-modified ^ silicone that is a water-soluble or nonionic surfactant is preferably compounded.

[0168] Of the hair cosmetic compositions of the present invention, a hair conditioning cosmetic composition comprises the following as exemplary compounding components: the component (A), the oil agent (B) and particularly the higher alcohol (B2-1), the surfactant (C), the alcohol (D), the water-soluble polymer (E) (e.g. as thickening agent of the water system), and also water, a pH adjusting agent, a preservative, and similar other components (M). From the perspective of adhesion characteristics to the hair, of the components (C), generally the cationic surfactant (C2) is preferably used as an essential component, and alkyltrimethylammonium chloride or a similar quaternary ammonium salt or diethylaminoethylamide stearate or a similar alkyl amidoamine is particularly preferable. Additionally, one or two or more types selected from a

dimethylpolysiloxane, an amino-modified silicone, and similar organo-modified silicones, an ester oil, a lanolin derivative, and a higher alcohol can be used preferably as the oil agent (B). Using the higher alcohol is particularly preferable from the perspective of forming an a-gel with the surfactant.

[0169] Additionally, from the perspectives of remaining on the hair and the conditioning effects to the hair, using a silicone is preferable, and selecting an amino-modified silicone or a

dimethylpolysiloxane with a high degree of polymerization is more preferable. Using a silicone with a high degree of polymerization that is a silicone gum is particularly preferable. The amino equivalent weight and the like of the modified silicone can be designed as deemed appropriate. Additionally, for the purpose of emulsifying these silicones and the like, it is particularly preferable that a combination of the silicone and one or more of the nonionic surfactant (C3) and the amphoteric surfactant (C4), other than the cationic surfactant, is used. The water-soluble polymer (E) may be preferably compounded. In this case, the component (E) is preferably a water-soluble polymer other than the cationic water-soluble polymer, and, from the perspective of conditioning effects, is particularly preferably a guar gum or similar natural water-soluble polymer, hydroxyethylcellulose or a similar semisynthetic water-soluble polymer. On the other hand, when using a combination of the component (A), the higher alcohol (B2-1), and the cationic surfactant (C2), the hair conditioning cosmetic composition can provide smooth passability of the fingers through the hair, without a feeling of sticking/squeaking both when the hair is wet after cleansing and when the hair is dry; and smooth combability and touch and a luxurious feeling to touch when dry. Moreover the hair will be free of unpleasant stickiness and the hair can be provided with a soft sense of being gathered. Furthermore, with the hair conditioning cosmetic composition of the present invention, these effects will have superior durability.

[0170] Of the hair cosmetic compositions, a hair styling cosmetic composition comprises the following as exemplary compounding components: the component (A), the oil agent (B), the surfactant (C), and the water-soluble polymer (E). The hair styling cosmetic composition of the present invention is not particularly limited and may have an oil-based raw material as the base material, or may have an aqueous raw material as the base material (i.e. may have the water (M) as the carrier). Including an oil agent as the component (B) is preferable with the hair styling cosmetic composition of the present invention and, depending on the form selected from liquid, cream-like, solid, paste-like, gel-like, mousse-like, and spray-like forms, the formulation and compounded components are determined. When the component (A) of the present invention is compounded, smooth combability and touch and a luxurious feeling to touch when dry and a soft sense of being gathered are provided to the hair; and the durability of these styling effects is superior.

[0171 ] Note that a combination of a high viscosity oil agent (B) exhibiting a wax-like or gum-like form at room temperature (25°C) and a liquid oil agent (B) that is a liquid at room temperature is preferable; and a combination of a high viscosity oil agent with a viscosity at room temperature of not less than 5,000 mPa*s (more preferably from 10,000 mPa-s to being a solid) and a low viscosity oil agent having a viscosity at room temperature of less than 5,000 mPa^«s (more preferably from 0.65 to 3,000 mPa^«s) is particularly preferable. Additionally, a combination of a polyvinylpyrrolidone, a carboxyvinyl polymer, or a similar vinyl-based polymer and another water-soluble polymer is preferable as the component (E).

[0172] Of the hair cosmetic compositions, a hair coloring cosmetic composition comprises the component (A) and at least one hair coloring component selected from the oxidation dye (K) and the direct dye (L). Particularly, combining the component (A) with these hair coloring components is advantageous because stability and the dispersibility of the hair coloring components can be improved, color retention on the hair and color development can be improved, and color variation can be eliminated. Therefore, the hair can be beautifully dyed. Additionally, using the direct dye (L) is advantageous because rinsing can be performed in a relatively easy manner.

[0173] The form of the cosmetic composition of the present invention is not particularly limited and in addition to an emulsion, can be in a liquid, cream-like, solid, paste-like, gel-like, powder-like, multi-layer, mousse-like, spray-like, or sheet-like form.

Examples

[0174] Hereinafter, the present invention is described with reference to examples, but it should be understood that the present invention is not limited to these examples. In the following compositional formulae, "M" represents an Me₃SiO group (or an Me₃Si group), "D" represents an Me₂SiO group, "M^H" represents an MeHSiO group, and "D^H" represents an MeHSiO group. Additionally, "Me" represents a methyl group.

[0175] Practical Example 1 : Synthesis of organopolysiloxane 1 488.28 parts by weight (mass) of an amino-modified organopolysiloxane (proportion of nitrogen atoms originating from amino groups (N%)= 2.4%) represented by an average composition formula M-D₃53.7-D*₂2.6-M (where D^* is a diorganosiloxy unit represented by

Me(NH₂C2H4NHC₃H₆-)Si0₂ 2, and 111.72 parts by weight (mass) of behenic acid (NAA-222S, manufactured by Nof Corporation, neutralization value=165.0 mgKOH/g) were placed in a reaction vessel. Then, pressure was reduced to not more than 40 mmHg while heating and agitating under nitrogen bubbling at 125°C. After 10 hours, it was confirmed that the N% had been consumed so as to be not more than 1.17% and the reaction was completed. Thus, an organopolysiloxane 1 was obtained. The organopolysiloxane 1 had a yellow vaseline form, and had a viscosity (at 25°C) of not less than 750,000 mPa-s, a melting point of about 55°C, and an N% of 1.14%.

[0176] Evaluation

Hair conditioners of Practical Example 2 and Comparative Examples 1 and 2 having the component formulations shown in Table 1 were prepared using the organopolysiloxane 1 obtained in Practical Example 1 , a known amino-modified organopolysiloxane (FZ-4671 (32% emulsion of the amino-modified organopolysiloxane)), and a known (gum-like)

organopolysiloxane having a high degree of polymerization (a solution in which SGM36 and a decamethyl pentacyclosiloxane (D5) are mixed at a weight (mass) ratio of 2:8). The cosmetic characteristics of each of the compositions were evaluated. Note that the numbers in Table 1 represent parts by weight (mass).

[0177] Hair conditioner manufacturing method

1) Component Nos. 1 to 4 and 9 to 11 were introduced into a 200 ml beaker and heated and dissolved at 80°C while mixing using a propeller mixer.

2) Separately, component Nos. 5 to 7 were heated and dissolved at 80°C.

3) The mixture of 1) was added to the mixture of 2) and emulsified while mixing.

4) The mixture of 3) was cooled while mixing, and component No. 8 was added at a temperature of not higher than 40°C.

^*2: 32% emulsion of the amino-modified organopolysiloxane

[0179] Evaluation criteria

A commercially available bundle of Chinese native hair (30 cm, 4 g, manufactured by Beaulax Co., Ltd.) that was bleached at room temperature for 10 minutes and then cleansed using a 10% sodium laureth sulfate solution was used as hair for evaluation. First, 10 panelists applied 0.3 g of the subject composition to the hair using the palms of their hands. The smoothness when applying and the feeling to touch (smoothness) before towel drying were evaluated as the usage benefits when wet. Then, the conditioning effects after drying (smoothness, luxuriousness, and softness) were evaluated as the usage benefits when dry. Each panelist was made to answer a questionnaire in which each criterion was scored on a scale of 1 to 5, with 1 being inferior, 5 being superior, and 2, 3, and 4 being mid-range scores. The scores were averaged and recorded as the evaluation results for sensation during use. The evaluation results are shown in Table 2.

[0180] Table 2

[0181] As is clear from Tables 1 and 2, with Practical Example 2, where the long chain amide-modified silicone · amino-modified silicone copolymer of Practical Example 1 was used, even though the hair was damaged by the bleaching, an appropriate degree of smoothness when applying, rinsing, and the like, and smoothness, luxuriousness, and softness after drying were displayed. Particularly, a silky feeling to touch not achieved by existing technologies was imparted as a result of providing both luxuriousness and smoothness.

[0182] With Comparative Example 1 where a silicone having only amino groups and not having long chain amide groups was used, while smoothness was superior, luxuriousness, particularly that after drying, was inferior. Additionally, with Comparative Example 2 where a silicone having neither amino groups nor long chain hydrocarbon groups was used, smoothness, softness, and sliding when applying were inferior.

[0183] Practical Example 3

5 parts by weight (mass) of the organopolysiloxane 1 of Practical Example 1 and 20 parts by weight (mass) of a dimethylorganopolysiloxane 6cs (SH200 6cs, manufactured by Dow Corning Toray Co., Ltd.) were heated and dispersed. Then, 5.5 parts by weight (mass) of a

polyoxyethylene tridecyl ether (Noigen TDS-50, HLB 10.5, manufactured by Dai-ichi Kogyo Seiyaku Co., Ltd.) and 3 parts by weight (mass) of a polyoxyethylene tridecyl ether (Noigen TDS-120, HLB 14.8, manufactured by Dai-ichi Kogyo Seiyaku Co., Ltd.) were added and thoroughly mixed and made uniform using a disper. Furthermore, the mixture was emulsified while gradually adding 66 parts by weight (mass) of ion exchanged water. The continuous phase was identified as an aqueous phase due to electrical conductivity. Thus, a milky cream-like oil-in-water emulsion was obtained.

[0184] Practical Example 4

Furthermore, a hair conditioner of Practical Example 4 was prepared having the formulation shown in Table 3, and the cosmetic characteristics thereof were functionally evaluated according to the Evaluation Criteria described above. Note that the numbers in Table 3 represent parts by weight (mass). The hair conditioner of Practical Example 4 had a smooth feeling to touch when applying and was easy to spread. Additionally, strength and body were felt even while maintaining sliding smoothness when rinsing. Furthermore, after drying, smoothness and luxuriousness were felt and a silky feeling to touch could be felt.

[0186] Hereinafter, specific formulations of the cosmetic composition of the present invention are described as Practical Examples of the present invention. However, it should be understood that the present invention is not limited to these examples. In these formulation examples, the organopolysiioxane 1 may be replaced by a different modified silicone according to the present invention (e.g. a product having a degree of polymerization longer than that of the siloxane backbone of the organopolysiioxane 1 , a product having more or less amino-containing groups, a product in which the modified content of the long chain alkyl groups is increased or decreased, and the like). Additionally, the organopolysiioxane 1 may be replaced by a mixture of two or more modified silicones according to the present invention.
