摘要：
Esters of citric acid or acetylcitric anhydride with compounds of at least 3 OH groups selected from the group consisting of polyglycerol, sugarcarboxylic acids, alkyl glucosides, derivatives of oligosaccharides, aminosorbitol, aminodisorbitol, glucosamine, triethanolamine and trishydroxyethylmelamine, each OH group of the alcohol component of the esters being esterified on average with from 0.15 to 1 molecule of citric acid or acetylcitric anhydride, are useful as additives in low-phosphate or phosphate-free detergents.
