Use of amphoteric polysaccharide compounds comprising cationic polymer chains (obtained by grafting and polymerization of ethylenic monomers onto anionic polysaccharides) e.g. for cosmetic treatment of keratin materials

摘要

Cosmetic use of amphoteric polysaccharide compounds (A) comprising cationic polymer chains, which is obtained by grafting and polymerization of ethylenic monomers (I) onto anionic polysaccharides (II) in the presence of a catalytic system based on potassium permanganate and sulfuric acid. Cosmetic use of amphoteric polysaccharide compounds (A) comprising cationic polymer chains, which is obtained by grafting and polymerization of ethylenic monomers of formula (I) onto anionic polysaccharides of formula (II) in the presence of a catalytic system based on potassium permanganate and sulfuric acid. R 1-R 3H or 1-22C monovalent hydrocarbon-based group; Q : mineral or organic anion; P : polysaccharide chain; X : optionally hydroxylated 1-18C divalent hydrocarbon-based group; An : ionic group (-C(=O)-O-V, -P(=O)-(O-V) 2or -S(=O) 2-O-V); V : H, alkali metal or alkaline-earth metal; and n : degree of substitution of polysaccharide compound with an anionic group (DS(-)) is 0.02-2. An independent claim is also included for a composition (B) comprising at least one agent and at least one (A) in a medium. [Image].
