## Abstract

Aqueous surfactant compositions containing in each case one or more alpha-sulfo fatty acid disalt, a sulfoketone, a specific cationic polymer, a soap, an inorganic salt of sulfuric acid, and water are disclosed. The compositions have good foaming ability, a pleasant sensory feel to the foam, good skin compatibility, and are suitable for cosmetic products, detergents, and cleaning products.

one or more sulfoketone (B) selected from a compound (F) and a compound (G),
in which compound (F) has general formula (VI)
R6CH2—CO—CHR7(SO3M8) (VI),
