COSMETIC USE OF AMPHOTERIC POLYSACCHARIDE COMPOUNDS CONTAINING CATIONIC POLYMER CHAIN(S)

摘要

The invention relates to the cosmetic use, especially for the cosmetic treatment of keratin materials, of amphoteric polysaccharide compounds containing cationic polymer chain(s), which may be obtained by grafting and polymerization of ethylenic monomers of formula (I), Q^- onto an anionic polysaccharide of formula (II): in the presence of a catalytic system based on potassium permanganate (KMnO₄) and sulfuric acid (H₂SO₄). The invention also relates to compositions comprising at least one cosmetic active agent and at least one of these amphoteric polysaccharide compounds, in a cosmetically acceptable medium.
