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 a mide surfactants, such as the C1-C17 fatty N-methyl glucamides, which may be contaminated with secondary amines. Such amine s 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.
