Abstract:
A composition comprising, in addition to conventional auxiliaries, an effective amount of at least one polymer complex consisting essentially ofa) from 0.5 to 30% by weight, based on the weight of said polymer complex, of hydrogen peroxide,b) from 50 to 99.5% by weight, based on the weight of said polymer complex, of at least one N-vinyllactam homo- or copolymer,c) from 0 to 15% by weight, based on the weight of said polymer complex, of a therapeutically active compound different from a) and d), andd) from 0.01 to 15% by weight, based on the weight of said polymer complex, of a colloidal metal or a metal salt wherein the metal is Ag,which composition is adapted for topical application for prophylaxis or for treatment of a bacterial or viral infection of skin, and which is obtained by mixing an effective amount of a powder of the polymer complex with the conventional auxiliaries, which powder of the polymer complex is obtainedi. by subjecting a solution of the N-vinyllactam polymer together with a hydrogen peroxide solution and a metal salt solution or a dispersion of the colloidal metal and optionally a solution comprising component c) to spray drying, spray-granulating or drying in a fluidized bed, orii. by reacting the N-vinyllactam polymer with hydrogen peroxide and a metal salt solution or a suspension of the colloidal metal in a fluidized bed.
