摘要：
Reaction products of polybasic acids and amino-containing compounds, which are obtainable by heating a mixture of (a) a polybasic carboxylic acid selected from the group consisting of citric acid, isocitric acid, aconitic acid, itaconic acid and/or tartaric acid and (b) an amino-containing compound in a molar ratio of (a) to (b) of from 1:0.1 to 1:10 to at least 80.degree. C. are used as additives in low-phosphate and phosphate-free detergents and cleaning agents.
