Abstract

Abstract The present invention relates to low irritating shampoo compositions containing (a) a betaine, (b) anionic surfactants consisting of (1) triethanolamine laurylsulfate and (2) one or more anionic surfactants selected from the group consisting of alkali metal alkylsulfates, N-acylamino acids or the salts thereof and polyoxyethylene alkyl ether sulfates and (c) a nonionic sufactant at a weight ratio of about 1:2.5-4:0.6-1 or about 1:1:2.6-3 being suitable for patients with dermatitis, particularly atopic dermatitis.
