Abstract (en)
[origin: WO2017198527A1] The invention relates to aqueous surfactant compositions comprising • one or more alpha-sulfofatty acid di-salts (A) of general formula (I), R1CH(SO3M1)COOM2 (I), wherein the group R1 is a linear or branched alkyl or alkenyl group with 6 to 18 C atoms and the groups M1 and M2 are selected independently of each other from the group consisting of H, Li, Na, K, Ca/2, Mg/2, ammonium and alkanolamines, • one or more sulfoketones (B) which are selected from the compounds (F) and the compounds (G), wherein the compounds (F) have the general formula (VI) R6CH2-CO-CHR7(SO3M8) (VI), wherein the groups R6 and R7 independently of one another represent a linear or branched alkyl group with 6 to 18 C atoms and the group M8 is selected from the group consisting of H, Li, Na, K, Ca/2, Mg/2, ammonium and alkanolamines, and wherein the compounds (G) have the general formula (VII) (SO3M9)R8CH-CO-CHR9(SO3M10) (VII), wherein the groups R8 and R9 independently of one another represent a linear or branched alkyl group with 6 to 18 C atoms and the groups M9 and M10 independently of one another are selected from the group consisting of H, Li, Na, K, Ca/2, Mg/2, ammonium and alkanolamines, and • water, wherein the quantity of compounds (A) is larger than the quantity of compounds (B), both relative to the entire aqueous surfactant composition, and wherein a boundary condition has to be met with respect to so-called ester sulfonates that is further specified in the patent claims. The compositions have a good foaming power and good skin tolerance and the foam has a pleasant sensory feel, and they are suitable for cosmetic agents as well as detergents and cleaning agents.
