Poly(vinylamine-vinylformamide) copolymers as antiperspirant agent

Abstract

The present disclosure relates to an antiperspirant cosmetic composition comprising, a poly(vinylamine-vinylformamide) copolymer having a molecular weight of from about 300 to about 20,000 g/mol in a total amount of from about 0.1 to about 20% by weight, an emulsifier in a total amount of from about 0.05 to about 10% by weight, and an oil component in a total amount of from about 0.05 to about 50% by weight %. The cosmetic has a pH of from about 2.5 to about 7.5, the poly(vinylamine-vinylformamide) copolymer is neutralized or polycationic, and the cosmetic contains an anion selected from chloride, phosphates, and sulphates. The cosmetic does not contain halides and/or hydroxyhalides of aluminium and/or zirconium. These polymers make it possible to provide antiperspirant cosmetic products that do not contain aluminium salts and/or zirconium salts yet are highly effective and have less staining on textiles.
