Patent

CA 2494842

The invention relates to the use of polymers in cosmetic preparations for hair. Said polymers can be obtained by (i) radically initiated copolymerisation of monomer mixtures consisting of (a) at least one cationic monomer or quaternisable monomer (b), optionally a water-soluble monomer, (c) optionally another radically copolymerisable monomer, (d) at least one monomer acting as a cross-linking agent and having at least two ethylenically unsaturated, non-conjugated double bonds, and (e) at least one regulator; and by (ii) subsequent quaternisation or protonation of the polymers, provided that a non-quaternised or only partially quaternised monomer is used as monomer (a).

L'invention concerne l'utilisation, dans des préparations capillaires cosmétiques, de polymères pouvant être obtenus (i) par copolymérisation initiée de façon radicalaire de mélanges de monomères composés (a) d'au moins un monomère cationique ou quaternarisable, (b) éventuellement d'un monomère soluble dans l'eau, (c) éventuellement d'un autre monomère pouvant être copolymérisé de façon radicalaire, (d) d'au moins un monomère agissant comme agent réticulant, comportant au moins deux doubles liaisons non conjuguées à insaturation éthylénique, et (e) d'au moins un régulateur ; et, (ii) par quaternarisation ou protonation consécutive du polymère, le monomère (a) étant un monomère non quaternarisé ou partiellellement quaternarisé.
