Abstract:
The present invention relates to polyglycerol partial esters of linear, unsubstituted carboxylic acids and bifunctional carboxylic acids with the provisos that the polyglycerol partial ester comprises an HLB-value from 2 to 10 and that the polyglycerol obtained by hydrolysis or alcoholysis of the polyglycerol partial ester comprises an average degree of polymerization of from 2 to 8 and at least 1% of the polyglycerol comprises cyclic structures. The present invention also relates to the preparation thereof and their use in fabric and textile care products.
