PROCESS FOR REDUCING THE LEVELS OF UNREACTED AMINO POLYOL CONTAMINANTS IN POLYHYDROXY FATTY ACID AMIDE SURFACTANTS

摘要

Polyhydroxy amines reacted with fatty acid esters yield polyhydroxy fatty acid amide surfactants, such as the C11-C17 fatty N-methyl glucamides, which may be contaminated with secondary amines. Such amines are acylated by a reaction with acetic anhydride. The resulting "clean" polyhydroxy fatty acid amide surfactants are preferred for use in the presence of oxidants, especially in the formulation of modern, colorless liquid detergents.
