The present invention relates to aqueous surfactant compositions comprising one or more α-sulfofatty acid disalts (A) of the general formula (I): R 1 CH(SO 3 M 1 )COOM 2 in which the group R 1 is a linear or branched alkyl or alkenyl group having 6-18 carbon atoms and the groups M 1 and M 2 are independently selected from H, Li, Na, K, Ca/2, Mg/2, ammonium and Alkanolamines, one or more N-acylglutamic acid compounds of general formula (II): M 3 OOC-CH 2 -CH 2 -CH(NH-CO-R 2 )-COOM 4 (II) ( B), wherein the radical R 2 is a linear or branched alkyl or alkenyl radical having 7-19 carbon atoms and the radicals M 3 and M 4 are independently selected from H, Li, Na, K, Ca/ 2. Mg/2, ammonium and alkanolamines, and water, with specific constraints to be observed. These compositions are transparent, storage-stable, are characterized by good foaming power and are suitable for cosmetics and also detergents and cleaners. |
