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 C1-C17 fattyN-methyl glucamides, which may be contaminated with secondary amines. Such amines are acylated by a reaction withacetic anhydride. The resulting "clean" polyhydroxy fatty acid amide surfactants are preferred for use in the presence ofoxidants, especially in the formulation of modern, colorless liquid detergents.
