摘要

Water-soluble or -dispersible polyurethanes prepared from components having active hydrogen groups, polyester diol(s) and diisocyanate(s), are used as auxiliary agents in cosmetics, in pharmaceuticals and in coatings for the textile, paper, printing, leather and adhesives industries. A cosmetic comprises water-soluble or water-dispersible polyurethanes prepared from the following components: (a) at least one polymer that has two active hydrogen atoms per molecule and is selected from polytetrahydrofurans, polysiloxanes and their mixtures; (b) at least one polyester diol; (c) at least one compound that has a molecular weight of 56-300 and contains two active hydrogen atoms per molecule; (d) at least one compound that has two active hydrogen atoms and at least one anionic or anionogenic group per molecule; and (e) at least one diisocyanate; provided that the polyurethane contains no units derived from primary or secondary amines containing ionic or ionogenic groups. An Independent claim is also included for a cosmetic composition containing at least one polyurethane as above.
