Description

  The present invention relates to a hair cosmetic composition, and more particularly to a hair cosmetic composition that imparts smoothness and moist feeling to hair.

  Conventionally, oils such as silicone oil (polyorganosiloxane), ester oil, hydrocarbon oil, etc. to give the hair smoothness (slipperiness), softness, moisturization, etc. according to consumer needs, Various hair cosmetic compositions containing a cationic surfactant or the like have been proposed.

  In particular, since silicone oil has a low surface tension, it can easily spread uniformly on the hair and can give excellent gloss. In addition, a wide range of viscous silicone oils can be used, and various tactile sensations can be given. Therefore, hair cosmetics using silicone oil are extensively disclosed in patent documents and the like.

  A polyorganosiloxane containing a 3-aminopropyl group and / or N- (2-aminoethyl) -3-aminopropyl group has excellent adsorptivity to hair, particularly excellent slipperiness when the hair is wet. Therefore, many hair cosmetics containing such silicone oil have been proposed. For example, it has been proposed to improve the fingering at the time of rinsing and drying by blending an amino-modified silicone oil containing a 3-aminopropyl group and having an amino equivalent of less than 4000 in a shampoo. (For example, see Patent Document 1)

In addition, hair cosmetics each containing an amino-modified silicone having a degree of polymerization of 517 or less and a silicone having a high degree of polymerization have been proposed. (For example, see Patent Document 2) The viscosity of the amino-modified silicone having a polymerization degree of 517 is expressed by Barry's formula representing the relationship between the molecular weight and the viscosity of polydimethylsiloxane: molecular weight = ((Log viscosity−1) /0.0123) ² Is about 2.5 Pa · s.

  In addition, hair cosmetics containing a mixture of amino-modified silicone and polyorganosiloxane gum have been proposed. (For example, see Patent Document 3) In Patent Document 3, the viscosity and amino group content of amino-modified silicone are widely defined and are not particularly limited, but the most preferable degree of polymerization is 50 to 500. The viscosity is estimated to be several Pa · s or less.

  Furthermore, a hair composition containing a polymer amino-modified silicone having a polymerization degree of 3,000 to 20,000 has also been proposed. (For example, see Patent Document 4) When the viscosity of the amino-modified silicone is determined using the Barry equation, the value is about 6,000 Pa · s or more.

  However, in the hair cosmetic compositions described in Patent Documents 1 and 2, the fingering at the time of drying was insufficient.

  In addition, in the hair cosmetic composition described in Patent Document 3, satisfactory fingering was not obtained for the hair.

Furthermore, the hair cosmetic composition described in Patent Document 4 is a so-called gum-like substance having almost no fluidity, and not only takes time for preparation but also cannot provide sufficient smoothness.

  According to the hair cosmetic composition of the present invention, it is possible to impart both excellent slipperiness and moist feeling that could not be obtained conventionally to the hair. Moreover, the effect can fully be expressed even if the hair is in a wet state or a dry state.

  Hereinafter, embodiments of the hair cosmetic composition of the present invention will be described.

The hair cosmetic composition of the embodiment of the present invention contains a polyorganosiloxane represented by the general formula: MD _x D ′ _y D ^B _v D ^C _w M.

Wherein M is an end-capped siloxy unit represented by the general formula: R ¹ _a R ² _b R ³ _c SiO _1/2 , D is a bifunctional siloxy represented by the general formula: R ¹ ₂ SiO _2/2 units, D 'is the general ^formula: difunctional siloxy unit represented by _{^{R 1 R 2 SiO 2/2, D}} B has the general ^formula: R ¹ R ₄ difunctional siloxy unit represented by _{SiO 2/2,} ^{D C} Represents a bifunctional siloxy unit represented by the general formula: R ¹ R ⁵ SiO _2/2 .

Here, R ¹ is the same as or different from each other, and each independently represents a hydrogen atom or a monovalent substituted or unsubstituted alkyl group or alkoxy group having 1 to 5 carbon atoms. Specific examples of R ¹ include a hydrogen atom, an alkyl group such as a methyl group, an ethyl group, a propyl group, and a butyl group, and an alkoxy group such as a methoxy group, an ethoxy group, a propoxy group, and a butoxy group. A methyl group is particularly preferable.

R ² represents a monovalent group (amino-containing group) containing an amino group. Although there is no restriction | limiting in particular as an amino-containing group, From a viewpoint of material acquisition, it is preferable that it is a 3-aminopropyl group or N- (2-aminoethyl) -3-aminopropyl group.

R ³ is the same as or different from each other, and represents a monovalent substituted or unsubstituted alkyl group, aralkyl group or aryl group having 6 to 30 carbon atoms . Specifically, alkyl groups such as hexyl group, octyl group, ethylhexyl group, decyl group, isodecyl group, lauryl group, myristyl group, cetyl group, stearyl group, oleyl group, and behenyl group, aryl moiety is phenyl group or carbon number An aralkyl group having a lower alkyl substituted phenyl group of 4 or less and the alkyl moiety being a lower alkyl group having 4 or less carbon atoms, such as a 2-phenylethyl group, a 2-phenylpropyl group, or the like, or a phenyl group or a carbon number of 4 The following lower alkyl-substituted phenyl groups, such as phenyl group and tolyl group. R ⁴ and R ⁵ represent a specific group among these R ^{3 s} , R ⁴ represents a monovalent substituted or unsubstituted alkyl group having 6 to 30 carbon atoms, and R ⁵ represents an aralkyl group.

Formula represents an alkyl / aralkyl / aryl-modified silicone amino-modified silicone copolymer used in the embodiment of the present invention: In ^{_{MD x D 'y D B v}} D C w M, the value of x is 10 to 2000 range Preferably, it is the range of 15-1500. When the value of x is less than 10, the resulting cosmetic composition is inferior in terms of smoothness (sliding property). When the value of x exceeds 2000, the alkyl / aralkyl / aryl-modified silicone / amino-modified silicone copolymer in the emulsion particles, which are destroyed with the volatilization of water after use, does not easily spread on the hair surface. I can't.

The value of y is in the range of 1-50, particularly preferably in the range of 1-20. When the value of y exceeds 50, it is inferior in terms of smoothness for dry hair. v and w are both 1 or more, and the value of v + w (= z) is in the range of 1 to 100, preferably in the range of 1 to 50. When the value of v + w (= z) exceeds 100, the smoothness imparted to the hair is inferior, which is not preferable.

  Furthermore, in the embodiment of the present invention, it is desirable that the amino equivalent of the alkyl / aralkyl / aryl-modified silicone / amino-modified silicone copolymer is 1,000 to 140,000. The amino equivalent means the weight of amino-modified polyorganosiloxane with respect to 1 molar equivalent of amino group. When the amino equivalent is less than 1,000, the effect of imparting smoothness to dry hair is reduced. On the other hand, when the amino equivalent is greater than 140,000, the effect of imparting smoothness to wet hair is reduced. In either case, it is not preferable.

  The alkyl / aralkyl / aryl-modified silicone / amino-modified silicone copolymer of the embodiment gives excellent smoothness to both wet and dry hair, but by using the silicone compound in combination, finer fineness is obtained. Can respond to tactile demands. In addition, when using together with another silicone, it is desirable to blend silicones beforehand and to emulsify and use the blended material.

  Examples of the silicone used in combination include polydimethylsiloxane (dimethicone) and cyclic polydimethylsiloxane (cyclomethicone). As polydimethylsiloxane, those having a wide range of viscosities of 0.05 to 20,000 Pa · s at 25 ° C. can be used, and smoothness for dry hair can be adjusted by blending. On the other hand, the cyclic polydimethylsiloxane can adjust the smoothness especially for wet hair.

  When the hair cosmetic is aqueous such as shampoo or rinse, the alkyl / aralkyl / aryl-modified silicone / amino-modified silicone copolymer or alkyl / aralkyl / aryl-modified silicone / amino-modified silicone copolymer used in the present invention It is desirable that the blend of the coalescence and the other silicone described above is pre-emulsified to form an emulsion before blending.

  By comprising in this way, the particle diameter of the silicone particle disperse | distributed in hair cosmetics can be controlled easily, and adjustment of the tactile sensation provided becomes easy. That is, an emulsion containing silicone particles having a large particle size is suitable for a rinse, a conditioner, etc., which is a type of cosmetic that is washed off after being applied, since the silicone content tends to remain on the hair, but the silicone particle size is too large. And there is a problem that stability in hair cosmetics is lowered. Therefore, the optimum particle size of the silicone particles varies depending on the hair cosmetics, and the particle size needs to be controlled.

  In the present invention, a known method can be used for producing an emulsion containing the alkyl / aralkyl / aryl-modified silicone / amino-modified silicone copolymer. Examples include emulsifying machines such as colloid mills, line mills, homomixers, and homogenizers, or emulsification using an anchor mixer and homomixer, or an emulsifier in which an anchor mixer and a disper mixer are integrated. It is not limited to this method.

  In addition, a surfactant and water are used for producing the emulsion. As the surfactant, any of an anionic surfactant, a cationic surfactant, a nonionic surfactant, and an amphoteric surfactant may be used, and these may be used alone or in admixture of two or more. it can.

  Anionic surfactants include dodecyl benzene sulfonic acid, octyl benzene sulfonic acid, polyoxyethylene lauryl sulfate, lauryl sulfate, tetradesense sulfonic acid, hydroxytetradesense sulfonic acid, and their sodium, potassium, triethanolamine Examples include salt.

  Cationic surfactants include lauryl trimethyl ammonium hydroxide, stearyl trimethyl ammonium hydroxide, dioctyl dimethyl ammonium hydroxide, distearyl dimethyl ammonium hydroxide, lauryl trimethyl ammonium chloride, stearyl trimethyl ammonium chloride, cetyl trimethyl ammonium chloride, dichloride chloride. Examples thereof include cocoyl dimethyl ammonium, distearyl dimethyl ammonium chloride, benzalkonium chloride, and stearyl dimethyl benzyl ammonium chloride.

  Nonionic surfactants include polyoxyethylene lauryl ether, polyoxyethylene fatty acid ester, polyoxyethylene sorbitan fatty acid ester, sorbitan fatty acid ester, glycerin fatty acid ester, polyoxyethylene hydrogenated castor oil, polyoxyethylene sorbitol fatty acid ester, etc. Can be mentioned.

  Examples of amphoteric surfactants include laurylamine oxide, lauryl betaine, cocoamidopropyl betaine and the like.

  The type of the surfactant is selected depending on the compatibility with other components in the hair cosmetic. For example, when the target hair cosmetic composition is an anionic composition such as shampoo, use of at least one surfactant selected from anionic surfactants, amphoteric surfactants and nonionic surfactants In the case of cationic compositions such as rinses and conditioners, it is preferable to use at least one surfactant selected from cationic surfactants, amphoteric surfactants and nonionic surfactants. The use of a nonionic surfactant is particularly preferred because the particle size of the emulsion is relatively easy to control and can be stably incorporated into both anionic and cationic compositions.

  Here, specific examples of the nonionic surfactant include polyoxyethylene (6) lauryl ether, polyoxyethylene (7) cetyl ether, polyoxyethylene (20) stearyl ether, polyoxyethylene (3) octylphenyl ether. , Polyoxyethylene (18) nonylphenyl ether, polyethylene glycol monostearate (EO14), polyethylene glycol distearate (EO80), polyoxyethylene (20) sorbitan, polyoxyethylene (20) hydrogenated castor oil, polyoxymonolaurate Ethylene (20) sorbitan, polyoxyethylene (20) sorbitan monopalmitate, polyoxyethylene (6) sorbitan monostearate, polyoxyethylene (20) sorbitan trioleate, polyoxyethylene (40) sorbitol tetraoleate, Monoleonic acid polio Siethylene (15) glyceryl, polyoxyethylene (15) glyceryl monostearate, sorbitan monopalmitate, polyoxyethylene (10) behenyl ether, polyoxyethylene (10) phytosterol, polyoxyethylene (10) polyoxypropylene (4 ) Cetyl ether, polyoxyethylene (5) stearylamine, polyoxyethylene (8) stearylpropylenediamine, polyoxyethylene (5) sodium cetyl ether phosphate and the like. Among these nonionic surfactants, those having an HLB value of 6 to 20 are preferably used in combination because the resulting emulsion has good stability.

  The blending amount of these surfactants is preferably in the range of 1 to 40% by weight, more preferably 2 to 20% by weight of the whole emulsion. If it is less than 1% by weight, it becomes difficult to disperse each component well, and if it exceeds 40% by weight, the stability of the emulsion decreases. Moreover, the blending amount of water as a dispersion medium of the emulsion is preferably in the range of 20 to 90% by weight, more preferably 30 to 80% by weight of the whole emulsion.

  In emulsification, the stability of the emulsion can be improved by neutralizing the amino group with an acid. Examples of the acid used at this time include organic acids such as acetic acid and lactic acid, and inorganic acids such as hydrochloric acid, sulfuric acid and phosphoric acid.

  Specific examples of the hair cosmetic composition according to the present invention include shampoos, rinses, conditioners, treatments, hair styling agents, hair mousses, hair creams and gels. The purpose of each cosmetic is not the same, but is consistent in giving a smooth touch to the hair. By using a hair cosmetic containing the alkyl / aralkyl / aryl-modified silicone / amino-modified silicone copolymer of the present invention, excellent smoothness can be imparted to both wet and dry hair.

  When the emulsion containing the alkyl / aralkyl / aryl-modified silicone / amino-modified silicone copolymer of the present invention is used as a rinsing effect agent or conditioner, one or more quaternary ammonium salts are added to the entire hair cosmetic composition. It is desirable to mix at a ratio of 0.1 to 5% by weight. When the quaternary ammonium salt is less than 0.1% by weight, the rinsing effect is insufficient, and when it exceeds 5% by weight, the viscosity of the hair cosmetic becomes high and difficult to use.

  Examples of the quaternary ammonium salt include cetyltrimethylammonium chloride, stearyltrimethylammonium chloride, behenyltrimethylammonium chloride, behenyldimethylhydroxetylammonium chloride, stearyldimethylammonium chloride, cetyltriethylammonium methylsulfate, and the like. Among these, stearyl trimethyl ammonium chloride, behenyl trimethyl ammonium chloride, and stearyl dimethyl benzyl ammonium chloride are particularly preferable.

  Further, when the emulsion containing the amino-modified polyorganosiloxane of the present invention is used as a cleaning agent such as shampoo, fatty acid soap, α-acyl sulfonate, alkyl sulfonate, alkyl naphthalene sulfonate, alkyl sulfate, Anionic surfactants such as polyoxyethylene alkyl ether sulfates, alkylamide sulfates, alkyl phosphates, alkylamide phosphates, alkyloyl alkyl taurine salts, N-acyl amino acid salts, glyceryl monostearate, monoleic acid Glycerin fatty acid esters such as glycerin, sorbitan fatty acid esters such as sorbitan stearate and sorbitan oleate, polyoxyethylene coconut oil fatty acid sorbitan, polyoxyethylene sorbitan monopalmitate, monostearic acid Polyoxyethylene sorbitan fatty acid esters such as reoxyethylene sorbitan, polyoxyethylene lauryl ether, polyoxyethylene alkyl ethers such as polyoxyethylene stearyl ether, polyethylene glycol monolaurate, polyethylene glycol distearate, and glycols distearate Nonionic surfactants such as esters, lauric acid diethanolamide, alkyl alkanolamides such as coconut oil fatty acid diethanolamide, lauryldimethylaminoacetic acid betaine, stearyldimethylaminoacetic acid betaine, 2-alkyl-N-carboxymethyl-N-hydroxyl Cetyl imidazolinium betaine, palm oil fatty acid amidopropyl betaine, lauric acid amide pro It is desirable to blend one or more amphoteric surfactants such as betaines such as pyrbetaine, aminocarboxylates, and imidazoline derivatives in a proportion of 5 to 40% by weight in the hair cosmetic. When the amount is less than 5% by weight, the washability and foaming property at the time of washing are inferior, and when it exceeds 40% by weight, the viscosity of the resulting hair cosmetic becomes high and difficult to use.

  In addition to the above components, the hair cosmetic composition of the present invention includes liquid components such as liquid paraffin, squalane, lanolin derivatives, higher alcohols, various ester oils, ethylene glycol, propylene glycol, glycerin, sorbitol polyethylene, depending on the purpose. Water-soluble oil such as glycol, moisturizer such as hyaluronic acid, chondroitinic acid, pyrrolidone carboxylic acid, thickener such as carboxyvinyl polymer, cation-modified cellulose ether derivative, polyvinylpyrrolidone derivative quaternary ammonium salt, diallyldimethylammonium chloride, polyamide A cationic polymer such as a derivative quaternary ammonium salt, polyoxyethylene polyalkylene, or polyamine, an ultraviolet absorber, a fragrance, or the like may be blended.

  In the hair cosmetic composition of the present invention, excellent smoothness and moist feeling can be imparted to both wet and dry hair. Such excellent tactile sensation cannot be obtained with conventional hair cosmetics.
