摘要:
Ampholytic copolymers which contain a molar excess of anionogenic and/or anionic groups, polyelectrolyte complexes which contain such an ampholytic copolymer, cosmetic and pharmaceutical compositions which contain at least one such copolymer or polyelectrolyte complex and the use of these copolymers and polyelectrolyte complexes are described.
