【発明の名称】ポリヒドロキシ脂肪酸アミド界面活性剤中の未反応アミノポリオール汚染物質の濃度を減少させる方法
Document Type and Number:
Japanese Patent JPH08501547
Kind Code:
A
Abstract:
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.
