Nonionic surfactant

摘要

Herein are disclosed N-long chain acyl-neutral amino acid polyglycerin esters composed of a polyglycerin having a degree of glycerin polymerization of not smaller than 4 and an N-long chain acyl-neutral amino acid having an acyl group with from 6 to 22 carbon atoms and a nonionic surfactant composition comprising, as an active ingredient, at least one of said N-long chain acyl-neutral amino acid polyglycerin esters, which are favorably safe and which, when incorporated in cosmetic compositions or percutaneous preparations, are sensorially good.
