The invention relates to: General formula (I): R 1 CH (SO 3 M 1 ) COOM 2 (I) in which the radical R 1 is linear or branched having 6 to 18 C atoms An alkyl or alkenyl group, the groups M 1 and M 2 independently of one another being selected from the group consisting of H, Li, Na, K, Ca / 2, Mg / 2, ammonium and alkanolamines One or more types of sulfoketones (B) selected from the above α-sulfo fatty acid disalts (A), compounds (F) and compounds (G), wherein the compounds (F) have the general formula (VI): R 6 CH 2 -CO-CHR 7 (SO 3 M 8 ) (VI) in which the radicals R 6 and R 7 independently of one another are linear or branched having 6 to 18 C atoms And the group M 8 is selected from the group consisting of H, Li, Na, K, Ca / 2, Mg / 2, ammonium and alkanolamines, and the compound (G) has the general formula (VII): (SO 3 M 9 ) R 8 CH-CO-CHR 9 (SO 3 M 10 ) (VII) (wherein the groups R 8 and R 9 independently of one another represent 6 to 18 C atoms The A linear or branched alkyl group, group M 9 and M 10 are each independently selected, H, Li, Na, K , Ca / 2, Mg / 2, from the group consisting of ammonium and alkanolamine An aqueous surfactant composition comprising one or more sulfoketones (B), and water, wherein the amount of compound (A) is greater than the amount of compound (B) (both are The boundary conditions have to be satisfied for the whole aqueous surfactant composition), the so-called ester sulfonates specified further in the claims. These compositions have good foaming power and good skin resistance, and the foam has a pleasant sensory feel, which makes them suitable for cosmetics as well as detergents and cleaners. 【Selection chart】 None |
