Aqueous surfactant compositions

An aqueous surfactant composition comprising

• one or more alpha-sulfo fatty acid disalt (A) of 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 alkanolamine,
• one or more N-acylglutamic acid compound (B) of 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,
• where the following provisos apply:
• a content of the compounds (A) and (B) in the aqueous surfactant composition is, based on the total aqueous surfactant composition, at least 5% by weight;
• if the aqueous surfactant composition comprises one or more ester sulfonate (E) of general formula (V),
• R5CH(SO3M7)COOR6 (V)
• in which the radical R5 is a linear or branched alkyl or alkenyl radical with 6 to 18 carbon atoms and the radical R6 is a linear or branched alkyl or alkenyl radical with 1 to 20 carbon atoms, where the radical R7 is an alkenyl radical or is branched only above 3 carbon atoms, and the radical M7 is selected from the group Li, Na, K, Ca/2, Mg/2, ammonium, and alkanolamines, the compounds (A), based on the totality of the compounds (A) and (E), must be present to 50% by weight or more;
• the weight ratio of the compounds (B):(A) in the aqueous surfactant composition is in the range from 2:1 to 6:1;
• the pH of the aqueous surfactant composition is 8 or less;
• the average transmission of the aqueous surfactant composition at 23° C.—measured using a TurbiScan MA 2000—is at least 80%.
