Citric acid esters of polyhydroxyle compounds and their use in washing and cleaning products

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