Aqueous surfactant compositions comprisingn one or more alpha-sulfo fatty acid disalt (A) of general formula (I)n nR 1 CH(SO 3 M 1 )COOM 2 (I),n in which the radical R 1 is a linear or branched alkyl or alkenyl radical having 6 to 18 carbon atoms and the radicals M 1 and M 2 , 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)n nR 6 CH 2 —CO—CHR 7 (SO 3 M 8 ) (VI),n in which the radicals R 6 and R 7 , independently of each other, are a linear or branched alkyl radical having 6 to 18 carbon atoms and the radical M 8 is selected from H, Li, Na, K, Ca/2, Mg/2, ammonium, and alkanolamine, and the compounds (G) have general formula (VII)n n(SO 3 M 9 )R 8 CH—CO—CHR 9 (SO 3 M 10 ) (VII),n in which the radicals R 8 and R 9 , independently of each other, are a linear or branched alkyl radical having 6 to 18 carbon atoms and the radicals M 9 and M 10 , independently of each other, are selected from H, Li, Na, K, Ca/2, Mg/2, ammonium and, alkanolamine, andn water, n 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. |
