Mixtures of quaternary polymeric acrylic ammonium salts, quaternary mono- or oligomeric ammonium salts and surfactants, their preparation and their use in cosmetic compositions

Abstract

Abstract 1. An aqueous composition of polymeric, quaternary ammonium salts, of monomeric to oligomeric, quaternary ammonium salts and of monionic or anionic surfactants, which composition has a pH value of 3 to 9 and contains at least (A) one ammonium salt which is soluble or micro-emulsifiable in aqueous surfactant systems and has a molecular weight distribution of 10**4 to 10**9 , the molecular weight of at least 5 per cent by weight of the polymeric salt being 10**7 to 10**9 , said salt containing recurring structural units of the formula see diagramm : EP0080976,P46,F1 and, optionally, in any order, at least one of the recurring structural units of the formulae see diagramm : EP0080976,P46,F2 see diagramm : EP0080976,P46,F3 and see diagramm : EP0080976,P46,F4 wherein A1 , A2 , A3 and A4 are each hydrogen or methyl, G1 and G2 are different from each other and are each -CN, -COOH or see diagramm : EP0080976,P46,F5 D1 and D2 are each oxygen or -NH-, E1 and E2 are each C1 -C4 alkylene which is unsubstituted or substituted by hydroxyl, R1 , R2 , R3 and R4 are each methyl or ethyl, Q is alkyl, C1 -C4 hydroxyalkyl or benzyl and Y1 (cation) is a halide, alkylsulfate or alkylphosphonate anion containing 1 to 4 carbon atoms in the alkyl moiety, (B) an ammonium salt which contains 1 to 3 quaternary nitrogen atoms and has a molecular weight of not more than 9 000, and (C) a nonionic surfactant, a surfactant having a positive and a negative charge in each molecule or an anionic surfactant which may be in zwitterion form, or mixtures thereof, with the proviso that if component (C) is an anionic surfactant, the polymeric ammonium salt used as component (A), in addition to containing structural units of the formula see diagramm : EP0080976,P46,F6 also contains structural units of the formula see diagramm : EP0080976,P47,F1 and the anionic surfactant has been at least partially reacted by ion exchange with components (A) and (B).
