摘要:
A mixture comprising a surfactant and a cosurfactant is proposed wherein the cosurfactant used is an amphiphilic comb polymer having a backbone with two or more side chains attached to the backbone, where the side chains differ from one another and/or the side chains differ from the backbone in their amphiphilic character.
摘要:
The present invention relates to an aqueous polymer dispersion which is obtainable by free-radical polymerization of a monomer mixture which comprises at least one amide-group-containing compound, at least one crosslinker and at least one monomer with at least one cationogenic and/or cationic group. The invention further relates to the polymers obtainable by drying such a polymer dispersion, and to cosmetic or pharmaceutical compositions which comprise such a polymer dispersion or such a polymer.

摘要:
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).
摘要:
The present invention relates to cosmetic and pharmaceutical compositions which comprise a copolymer with anionogenic and/or anionic groups which is obtainable by free-radical polymerization of a monomer mixture in the presence of a polyfunctional regulator with at least three functional regulating groups. The invention further relates to a method of producing such a copolymer and to the copolymers obtainable by this method.
