Abstract
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.
Claims6
An N-long chain acyl-neutral amino acid polyglycerin ester represented by the following general formula (I):
- wherein
- n is at least 2, and
- X is selected from the group consisting of:
- a hydrogen atom and
- an N-long chain acyl-neutral amino acid residue comprising an acyl group which contains 6 to 22 carbon atoms which may be straight- or branched-chained and saturated or unsaturated;
- wherein at least one X is an N-long chain acyl-neutral amino acid residue comprising an acyl group which contains 6 to 22 carbon atoms which may be straight- or branched-chained and saturated or unsaturated, and wherein the degree of glycerin polymerization ranges from 4 to 10.
