Abstract

A cosmetic composition comprises a) an N-acyl amino acid compound selected from the group consisting of N-acyl amino acid, its isomers, its salts, derivatives thereof, and mixtures thereof, and b) hexyldecanol.

Claims

1. A cosmetic composition comprising:

a) an N-acyl amino acid compound selected from the group consisting of N-acyl amino acid, its isomers, its salts, derivatives thereof, and mixtures thereof and
