Abstract

The invention relates to polyglycerol partial esters of saturated or unsaturated, linear or branched fatty acids and polyfunctional carboxylic acids, which are obtainable by esterification of a polyglycerol mixture with saturated or unsaturated, linear or branched fatty acids having 12 to 22 carbon atoms and polyfunctional carboxylic acids having 4 to 54 carbon atoms and a mean functionality of from 2 to 2.4, the degree of esterification of the polyglycerol mixture being between 30 and 75%.
