Abstract: Disclosed herein are compositions including (A) at least one polymer including (a) a core that bears one to 3 moieties of the general formula (I), where Z are different or the same and selected from C5-C20-alkylene where in the C5-C20-alkylene at least one C-atom is replaced by an N-atom that bears a polyalkylene chain and where the C-atoms in the C5-C20-alkylene may be non-substituted or substituted with one or more O—C1-C4- alkyl groups, A1 are different or the same and selected from C1-C12-alkylene, C6-arylene, and C3-C12-cycloalkylene where C1-C12-alkylene and C3-C12-cycloalkylene may be non-substituted or substituted with one or more O—C1-C4-alkyl groups or OH groups and wherein C3-C12-cycloalkylene may bear one to three methyl groups, or based on citric acid, X1 is selected from hydrogen, methyl, ethyl and combinations of at least two thereof, and n is in a range of from 1 to 100, and (b) polyalkylene oxide chains.
