摘要

Water-soluble or waterdispersible polyesters obtainable by condensation of tartaric acid or derivatives thereof alone or by condensation of mixtures of tartaric acid or derivatives thereof and citric acid with or without alcohols, watersoluble polyalkylene glycols or water-soluble polyaddition products of alkylene oxides with alcohols, fatty acids, alkylphenols or alkylamines and with or without at least dibasic carboxylic acids are suitable for use as detergent additives.
