The general formula (I): R 1 CH(SO 3 M 1 )COOM 2 (I) [wherein radical R 1 is a linear or branched alkyl or alkenyl radical having 6 to 18 carbon atoms, radicals M 1 and M 2 are - independently of each other - H, Li, Na, K, Ca/2, Mg/2, selected from the group of ammonium and alkanolamines] of at least one alpha-sulfo fatty acid disalt (A), of the general formula (II): R 2 -CO-NH-(CH 2 ) y -N + (CH 3 ) 2 -CH 2 -COO- (II) at least one amidoalkylbetaine (B), wherein the radical R 2 is a linear or branched alkyl or alkenyl radical having 7 to 19 carbon atoms and the index y is an integer in the range from 2 to 4, and Aqueous surfactant compositions comprising water are proposed, wherein certain limiting conditions are observed. The composition is transparent, storage-stable, characterized by good foaming ability and good viscosity, and is suitable for cosmetics and also detergents and cleaning agents. |
