摘要

Esters are disclosed of citric acid or acetylcitric acid anhydride with compounds containing at least 3 OH groups selected in the group formed by polyglycerine, sucrocarboxylic acids, alkylglucosides, derivates of oligosaccharides, aminosorbit, aminodisorbit, glucosamine, triethanolamine and trishydroxyethyl-melamine, in which each OH group of the ester alcohol components is esterified in average with 0.15 to 1 molecule citric acid or acetylcitric acid anhydride. Also disclosed is the use of these citric acid esters as additives to phosphate-poor or phosphate-free washing and cleaning products.
