Aqueous surfactant compositions comprisingone or more alpha-sulfo fatty acid disalt (A) of general formula (I)R1CH(SO3M1)COOM2 ； ；(I),in which the radical R1 is a linear or branched alkyl or alkenyl radical having 6 to 18 carbon atoms and the radicals M1 and M2, independently of each other, are selected from H, Li, Na, K, Ca/2, Mg/2, ammonium, and alkanolamine,one or more sulfoketone (B) selected from compounds (F) and compounds (G)wherein the compounds (F) have general formula (VI)R6CH2—；CO—；CHR7(SO3M8) (VI),in which the radicals R6 and R7, independently of each other, are a linear or branched alkyl radical having 6 to 18 carbon atoms and the radical M8 is selected from H, Li, Na, K, Ca/2, Mg/2, ammonium, and alkanolamine,and the compounds (G) have general formula (VII)(SO3M9)R8CH—；CO—；CHR9(SO3M10) (VII),in which the radicals R8 and R9, independently of each other, are a linear or branched alkyl radical having 6 to 18 carbon atoms and the radicals M9 and M10, independently of each other, are selected from H, Li, Na, K, Ca/2, Mg/2, ammonium and, alkanolamine, and water,wherein the amount of the compound (A) is greater than the amount of the compound (B), both based on the total aqueous surfactant composition. The compositions have good foaming ability, good skin compatibility, a pleasant sensory feel to the foam, and are suitable for cosmetic products, detergent, and cleaners.
