[0006]

BEST MODE FOR CARRYING OUT THE INVENTION (1) A polymer having a single amino acid residue and / or a salt thereof, which is an essential component of the cosmetic of the present invention, is a polymer having a single amino acid residue. And / or a salt thereof is contained as an essential component. Here, the polymer having a single amino acid residue means a generic name of a polymer in which a constituent monomer itself is a single amino acid or a polymer in which an amino acid residue is chemically bonded to a constituent monomer is polymerized. Specifically, a single amino acid is linked by a peptide bond, or a polypeptide such as polyaspartic acid, polyglutamic acid, or polylysine, or a polymer or copolymer of acrylic acid or methacrylic acid is linked with an amino acid as a side chain by a peptide bond. Amino acid pendant type polymers such as polymethacryloyl lysine can be preferably exemplified. These may be synthesized according to a conventional method, or raw materials already on the market may be used. As a synthetic method, a method in which a single amino acid is polymerized using a peptide synthesis reagent such as DCC or a halogenating agent such as thionyl chloride is allowed to act on acrylic acid or methacrylic acid to form an acid chloride, and then an alkaline condition is applied. Below, a method of reacting with an amino group of an amino acid such as lysine or glycine to form an N- (meth) acryloyl amino acid, and adding a polymerization initiator thereto to polymerize can be exemplified.
In addition, preferred commercial products include "Aquadew SPA-30" (polyaspartic acid) sold by Ajinomoto Co., Inc., "PM-lysine" (polymethacryloyl lysine) sold by Gifu Shellac Co., Ltd., and the like. It can be preferably exemplified. The average molecular weight of these is preferably 1000 to 100000, and 2000 to 1
0000 is more preferable. Further, as these salts, both salts with alkali and salts with acid are considered, but as salts with alkali, alkali metal salts such as sodium salt, potassium salt, etc., alkali salts such as calcium salt, magnesium salt etc. Examples thereof include organic amine salts such as earth metal salts, ammonium salts, triethanol salts and triethylamine salts, basic amino acid salts such as lysine salts and arginine salts, and salts with acids include hydrochlorides, sulfates and nitrates. Examples thereof include mineral acid salts such as phosphate, citrate, oxalate, organic acid salts such as malonate, carbonate, mesylate, tosylate and the like. These components may contain only one kind, or may contain two or more kinds in combination. In the cosmetic of the present invention, in order to contribute to imparting sufficient smoothness together with the silicones described below, the content thereof is 0.01 to a total amount based on the total amount of the cosmetic.
It is preferably 5% by weight, more preferably 0.05 to 1% by weight. This is because if it is too small, the smoothness-imparting effect may not be exhibited, and if it is too large, usability such as expression of stickiness may be impaired.

(2) Silicone which is an essential component of the present invention The cosmetic of the present invention contains silicone as an essential component. The silicone is not particularly limited as long as it has an alkyl group such as a methyl group and a silicon-oxygen-silicon bond, and examples thereof include alkylpolysiloxane, crosslinked alkylpolysiloxane, trialkylsiloxysilicic acid, and alkyl. Polysiloxane network polymer amodimethicone, polyether-modified silicone and the like can be preferably exemplified, and those having a solid or high viscosity are more preferable as properties. Here, as high viscosity, 3000 m at 1 atm 25 ° C
It means Pascal / sec or more. Particularly preferred is 1) methylpolysiloxane, cross-linked methylpolysiloxane or trimethylsiloxysilicic acid structure, which is a highly viscous liquid or solid, or 2) amodimethicone or polyether modified silicone is more preferred, Viscosity of 30,000 mPas as high viscosity liquid of 1)
Cal / sec or more can be exemplified, and more preferably 35,000 mPascal / sec to 50,000 m.
An example is Pascal / sec. As the solid substance, a solid substance having elasticity called a so-called silicone elastomer can be preferably exemplified. These high-viscosity or solid silicones may contain only one kind, or may contain two or more kinds in combination. In the cosmetic of the present invention, in order to sufficiently exert the effect of imparting the morphologically improving effect of the skin such as the effect of imparting smoothness, the total amount of these silicones is 0.05 to the total amount of the cosmetic. 10% by weight is preferable, and 0.1
5% by weight is more preferable. This is because if it is too small, the effect may not be exhibited, and if it is too large, the usability may be impaired.

(3) Cosmetic of the present invention The cosmetic of the present invention contains the above essential components and has an excellent effect of imparting smoothness. Therefore, in the cosmetic of the present invention, this effect which has hitherto depended on animal raw materials such as cow can be exhibited without using animal raw materials. Therefore, in the cosmetic of the present invention, a form containing no raw material derived from land animals such as bovine collagen, beef tallow, lanolin, and placenta extract can be particularly preferably exemplified. Since the cosmetics of the present invention are excellent in the effect of imparting smoothness to the skin and hair, basic cosmetics such as emulsions and creams, undermakeup cosmetics, makeup cosmetics such as foundations, hair creams, hair lotions, and hair styling products. Examples thereof include hair cosmetics such as rinses and shampoos, body shampoos, cleansing cosmetics such as facial cleansers, and of these, application to hair cosmetics is particularly preferable. This is because the cosmetic of the present invention exerts an excellent smoothness-imparting effect even on hair which does not exhibit the smoothness-imparting effect of a normal cosmetic. The cosmetics of the present invention may contain optional components usually used in cosmetics, in addition to the above essential components. Examples of such optional components include hydrocarbons such as petrolatum and microcrystalline wax, esters such as jojoba oil and cetyl isooctanate, triglycerides such as olive oil, and higher alcohols such as octadecyl alcohol and oleyl alcohol.

Preferable examples include antioxidants and cationized polymers such as cationized cellulose and cationized guar gum. Among these, particularly preferred are relatively long dihydric alcohols such as 1,3-butanediol, 1,2-pentanediol and isoprene glycol, phenoxyethanol which is a non-paraben preservative, and cationized polymers. is there. The dihydric alcohols have the effect of enhancing the smoothness-imparting effect while increasing the antimicrobial property. To obtain such an effect, the total amount is 5 to 25% by weight based on the total amount of the cosmetic. It is preferable to contain it. Phenoxyethanol can prevent the skin roughness and hair roughening that are rarely caused by parabens, and its content is preferably 0.1 to 1% by weight based on the total amount of the cosmetic. The cationized polymers are excellent in the action of maintaining the imparted smoothness, and it is preferable that the cationized polymers are contained in an amount of 0.01 to 1% by weight based on the total amount of the cosmetic. The cosmetic of the present invention can be produced by treating these essential components and optional components according to a conventional method. The thus-obtained cosmetic composition of the present invention has an excellent effect of imparting smoothness to the skin and hair.
