PURPOSE:The titled stable composition having an adjusted pH of a system of 1.5-6, properties mild to the skin, suppressing hydrolysis at high temperature, obtained by adding a compound having a specific inductive capacity to a cosmetic composition comprising an amino acid alkyl ester salt as a base. CONSTITUTION:A cosmetic composition comprising an amino acid alkyl ester salt as a base material is blended with 5.0-50.0wt% preferably 20.0-50.0wt% compound having a specific inductive capacity at 25 deg.C of 5.0-40.0, and adjusted to pH of 1.6-6. For example, an inorganic acid such as hydrochloric acid, sulfuric acid, and organic acid such as acetic acid, tartaric acid, etc. is used as the pH adjustor. Isopropyl alcohol, propylene glycol, 1,3-butylene glycol, etc. may be cited as the compound having a specific inductive capacity of 5.0-40.0. Glycinecetyl ester hydrochloride, etc. may be cited as the base material of the cosmetic composition. |
