摘要:
The invention relates to cosmetic preparations which comprise at least one polymer A which contains at least one ester of (meth)acrylic acid, at least one olefinically unsaturated anionogenic or anionic compound, at least one polyester or polyether having at least two radically polymerizable, olefinically unsaturated double bonds and optionally other olefinically unsaturated compounds polymerized into it.
摘要:
The invention relates to copolymers which contain ethyl methacrylate, at least one α,β-ethylenically unsaturated compound containing amide groups, and at least one monoethylenically unsaturated carboxylic acid polymerised therein. The invention also relates to cosmetic and pharmaceutical agents containing at least one copolymer of said type, and to the use of said copolymers.
摘要:
The invention relates to a method for producing (meth) acrylic acid esters (F) of hydroxy-functional flavoring agents (A), wherein at least one hydroxy-functional flavoring agent (A), in the presence of at least one enzyme (E), is esterified with (meth) acrylic acid (S) or transesterified with at least one (meth) acrylic acid ester (D), wherein the reaction occurs in the absence of solvents in the case of transesterification.
摘要:
The present invention relates to the use of cationic polymers, obtainable by radical copolymerization of a) 60 to 99 mol% of at least one 1-vinyl imidazole monomer, b) 1 to 40 mol% of at least one radically polymerizable, quaternizable monomer b1) or methacrylic acid b2), and c) 0 to 30 mol% of at least one additional radically copolymerizable monomer different from a) and b) in hair cosmetic products.
摘要:
The present invention relates to compositions, comprising at least one polymer a) having cationic and/or catiogenic groups and a molecular weight Mw in the range of 10,000 to 5 million, and at least one polymer b), which was produced in the presence of polymer a).
摘要:
The present invention relates to a process for preparing polymers by free-radical polymerization in solution, which is characterized in that the polymerization initiator used is an ethanol-soluble initiator and the solution polymerization is performed in an alcoholic solvent which contains from 5 to 50% by weight of water.
摘要:
The invention relates to copolymers containing, while being incorporated by polymerization, between 25 and 80 % by weight of tert. butyl (meth)acrylate, 2 to 60 % by weight of hydroxyalkyl (meth)acrylate, 10 to 40 % by weight of an anionic or anionogenic, radically polymerizable, olefinically unsaturated compound, which is or comprises methacrylic acid, and optionally contains up to 30 % by weight of another radically polymerizable olefinically unsaturated compound. The invention also relates to the use of copolymers of this type in cosmetic preparations and to these cosmetic preparations.
摘要:
The present invention relates to water or water-alcohol compositions containing at least one cationic polymer a) and at least one polymer b) with a molecular weight M W of at most 200,000 g/mol which contains polymerized N-vinylimidazole. The invention further discloses a method for the production of such compositions and the use of such compositions in cosmetics.
