Polyoxyalkylene sterol ether derivative and / or a polyoxyalkylene ence ethanol ether derivatives, and external compositions containing the same

摘要

PROBLEM TO BE SOLVED: To provide a new structure ionic polyoxyalkylene sterol ether derivative and/or a polyoxyalkylene stanol ether derivative which effectively act on skins and hairs to have an excellent chapped skin-restoring effect, and an excellent damaged hair-restoring effect, and to provide external preparation compositions such as medicines or cosmetics containing the same.SOLUTION: It has been found that the sulfate and/or its salt, phosphate and/or its salt, alkylcarboxylic acid and/or its salt, carboxylate ester and/or its salt, and quaternary ammonium compound of the polyoxyalkylene sterol ether and/or the polyoxyalkylene stanol ether have remarkably excellent these effects. These can be used to simply produce skin external preparation compositions, such as medicines or cosmetics, which efficiently act on skins and hairs to exhibit excellent skin-restoring effects and damaged hair-restoring effects.
