Suggested are aqueous surfactant compositions containing One or more alpha-sulfofatty acid disalts (A) of general formula (I), R 1 CH (SO 3 M 1 ) COOM 2 (I), in which the radical R 1 denotes a linear or branched alkyl or alkenyl radical having 6 to 18 C atoms and the radicals M 1 and M 2 - independently of one another - are selected from the group H, Li, Na, K, Ca / 2, Mg / 2, ammonium and alkanolamines, One or more N-acyl-amino acid compounds (B) which are selected from the group consisting of glycinates of general formula (IIa), sarcosinates of general formula (IIb), α-alaninates of general formula (IIc) and β- Alaninates of the general formula (IId) R 23 -CO-NH-CH 2 -COOM 13 (IIa) R 23 -CO-N (CH 3 ) -CH 2 -COOM 13 (IIb) R 23 -CO-NH-CH (CH 3 ) -COOM 13 (IIc) R 23 -CO-NH-CH 2 -CH 2 -COOM 13 (IId) wherein in the compounds (IIa), (IIb), (IIc) and (IId) the radical R 23 is a linear or branched alkyl or alkenyl radical having 7 to 19 carbon atoms and the radical M 13 is selected from the group H. , Li, Na, K, Ca / 2, Mg / 2, ammonium and alkanolamines, • water, with respect to so-called ester sulfonates a defined in the claims in more detail boundary condition is observed. These compositions have a good foaming power and a pleasant sensory properties of the foam and a good skin compatibility and are suitable for cosmetic products and detergents and cleaners. |
