Cosmetic, pharmaceutical and dermatological products containing an electrolyte

An electrolyte-containing cosmetic, dermatological or pharmaceutical composition comprising an electrolyte and which comprises at least one copolymer obtained by free-radical copolymerization of

• A) acryloyldimethyltaurine and/or acryloyldimethyltaurates,
• B) optionally, one or more further olefinically unsaturated, noncationic, comonomer which has at least one oxygen, nitrogen, sulfur or phosphorus atom and has a molecular weight of less than 500 g/mol,
• C) optionally, one or more olefinically unsaturated, cationic comonomer which has at least one oxygen, nitrogen, sulfur or phosphorus atom and has a molecular weight of less than 500 g/mol,
• D) optionally, one or more silicon-containing component capable of free-radical polymerization and having a functionality of at least one,
• E) optionally, one or more fluorine-containing component capable of free-radical polymerization and having a functionality of at least one,
• F) optionally, one or more olefinically mono- or polyunsaturated, macromonomer each possessing at least one oxygen, nitrogen, sulfur or phosphorus atom and having a number-average molecular weight of greater than or equal to 200 g/mol, the macromonomer not being a silicon-containing component D) or fluorine-containing component E), and where the at least one macromonomer is of formula (IV)
• in which
• R3, R4, R5, and R6 independently of one another are hydrogen or n-aliphatic, iso-aliphatic, olefinic, cycloaliphatic, arylaliphatic or aromatic (C1–C30) hydrocarbon radicals,
• v and w independently of one another are from 0 to 500, the sum of v and w is on average ≦1, and
• V is a bridge selected from the group consisting of —O—, —C(O)—, —C(O)—O—, —S—, —O—CH2—CH(O—)—CH2OH, —O—CH(OH)—CH2O—, —O—SO2—O—, —O—SO2—O—, —O—SO—O—, —PH—, —P(CH3)—, —PO3—, —NH—, and —N(CH3)—,
• G) optionally, the copolymerization taking place in the presence of at least one polymeric additive having number-average molecular weights of from 200 g/mol to 109 g/mol,
• H) with the proviso that component A) is copolymerized with at least one component selected from one of component D) to G).
