PURPOSE:A cosmetic composition for providing the skin and hair with smoothness by continuous use, containing specific amounts of an oil-soluble vitamin and a mono-N-long-chain acyl basic amino acid lower alkyl ester. CONSTITUTION:A cosmetic composition containing (A) 0.01wt.ppm-1wt% oil- soluble vitamin, preferably vitamin A such as retinal, provitamin A, vitamin E such as alpha-, beta-, gamma-, or delta-tocophernol, etc., and (B) 0.1-10wt% mono-N-long-chain acyl basic amino acid lower alkyl ester (lysine, gamma-diamionobutyric acid, etc., is used as the basic amino acid and acyl group is 8-22C saturated or unsaturated aliphatic acid residue).

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a cosmetic composition for imparting smoothness to the skin and hair, preferably with continued use.

[Prior Art] Conventionally, cosmetic compositions capable of imparting smoothness to the skin or hair include higher alcohols such as cetyl alcohol, stearyl alcohol, and behenyl alcohol.

Cosmetic compositions containing as an active ingredient quaternary ammonium n1 typified by alkyltrimethylammonium chloride and alkyldimethylammonium chloride are known. However, the effect was not satisfactory.

[Object of the Invention] An object of the present invention is to provide a cosmetic composition that can impart excellent smoothness to the skin and hair, preferably with continued use.

[Summary of the Invention] This invention provides oil-soluble vitamins on a weight basis.
Provided is a cosmetic composition containing 1% to 1% p-layer and 0.1% to 10% mono N-long chain acyl basic amino acid lower alkyl ester.

[Effect of the invention] According to this invention, the expression of the physiologically active effect originally possessed by oil-soluble vitamins on the skin and hair roots is promoted, the condition of the skin and hair is adjusted, and continuous use for about 7 days or more is promoted. As a result,
Improves the smoothness of skin and hair.

DETAILED DESCRIPTION OF THE INVENTION The first essential component of the compositions of this invention is a mono N-long chain acyl basic amino acid lower alkyl ester group. Examples of the basic amino acids constituting the mono N-long chain acyl basic amino acid lower alkyl ester salt include natural amino acids such as ornitino, lysine, and arginine. Furthermore, synthetic amino acids such as α,γ-diaminoacetic acid can also be used. These may be optically active or racemic, and the acyl group is a saturated or unsaturated fatty acid residue having 8 to 22 carbon atoms. These may be natural or synthetic; single fatty acid residues such as tellaroyl, myristoyl, valmitoyl, and stearoyl;
Also, natural mixed fatty acid residues such as coconut oil fatty acid residues and beef tallow fatty acid residues can be employed. Suitable lower alkyl ester components include methyl ester, ethyl ester, propyl ester, butyl ester, pentyl ester, and octyl ester. The salts include inorganic acid salts, such as hydrochloride or sulphate, or, for example, acetate, tartrate, citrate, p
-) luenesulfonate, fat salt tolerant, acidic amino salt,
Alternatively, organic acetate salts such as pyroglutamate can be used. Among these, hydrochloride, L or OL-
Preferred are the pyrrolidone carboxylate and acidic amino acid salt forms.

Seven-N-long chain acyl basic amino acid lower alkyl ester is contained in an amount of 0.1 to 10% by weight based on the total amount of the composition. If it is less than 0.1% by weight, it will be difficult to achieve the effects of this invention, and if it is more than 10%, it will be difficult to obtain a stable system.

The second essential ingredient of the composition of this invention is oil-soluble vitamins. Preferred oil-soluble vitamins include the following.
