Abstract:
Aqueous surfactant compositions containing one or more alpha-sulfo fatty acid disalts (A) of the general formula (I), R1CH(SO3M1)COOM2 (I), in which the radical R1 is a linear or branched alkyl or alkenyl radical with 6 to 18 carbon atoms and the radicals M1 and M2, independently of one another, are selected from the group H, Li, Na, K, Ca/2, Mg/2, ammonium and alkanolamines, one or more N-acylglutamic acid compounds (B) of the general formula (II), M3OOC—CH2—CH2—CH(NH—CO—R2)—COOM4 (II) in which the radical R2 is a linear or branched alkyl or alkenyl radical with 7 to 19 carbon atoms and the radicals M3 and M4, independently of one another, are selected from the group H, Li, Na, K, Ca/2, Mg/2, ammonium and alkanolamines, and water, with specific limiting conditions, are disclosed. The compositions are transparent, storage-stable, exhibit good foaming ability, and are suitable for cosmetic products, detergents, and cleaners.
