New copolymers containing ROD and COIL blocks, useful as surfactants and rheological agents, particularly in cosmetic compositions, in which the ROD component is a poly(amino acid)

摘要

Block copolymer (A) comprises at least one block with a variable conformation (COIL) linked to at least one block with a restricted conformation (ROD), where ROD is composed, at least in part, of peptide, or analogous, motifs and at least some of the free hydrogens in these motifs form non-covalent hydrogen bonds within ROD.
