What is proposed is aqueous surfactant compositions comprisingone or more alpha-sulfo fatty acid disalts (A) of the general formula (I),R1CH(SO3M1)COOM2 (I)in which the radical R1 is a linear or branched alkyl or alkenyl radical with 6 to 16 carbon atoms and the radicals M1 and M2—independently of one another—are selected from the group H, Li, Na, K, Ca/2, Mg/2, ammonium and alkanolamine,one or more alkyl glycosides (B) of the general formula (II),R2O-[G]p (I)in which R2 is an alkyl and/or alkenyl radical with 8 to 18 carbon atoms, G is a sugar radical with 5 or 6 carbon atoms and p is numbers between 1 and 10,and water,where specific limiting conditions are to be observed.These compositions have excellent foaming ability and are suitable for use in cosmetic products.
