Abstract

What are proposed are aqueous surfactant compositions comprising one or more of each of alpha-sulfo fatty acid disalts, sulfo ketones, alkyl (ether) sulfates, soaps, inorganic salts of sulfuric acid and water, where the structures of the compounds mentioned and boundary conditions that are to be observed can be found in the patent claims. These compositions have good foaming ability and pleasant sensory properties of the foam and good skin compatibility and they are suitable for cosmetic agents as well as detergents and cleaner.
