The invention provides acidic cosmetic, dermatological, and pharmaceutical agents comprising at least one copolymer obtainable by free-radical copolymerization of

A) acryloyldimethyltaurine and/or acryloyldimethyltaurates,

B) optionally, one or more further olefinically unsaturated, noncationic comonomers,

C) optionally, one or more olefinically unsaturated, cationic comonomers,

D) optionally, one or more silicon-containing component(s),

E) optionally, one or more fluorine-containing component(s),

F) optionally, one or more macromonomers,

G) the copolymerization taking place if desired in the presence of at least one polymeric additive,

H) with the proviso that component A) is copolymerized with at least one component selected from one of the groups D) to G).
