    Abstract: The present invention is related to a method for purifying crude α-sulfo fatty acid salt obtained by the reaction of fatty acid and sulfur oxides, comprising the following steps: a) diluting the crude α-sulfo fatty acid in a solvent and adjusting the ph from 2 to 4; b) heating up the slurry of a-sulfo fatty acid salt obtained in the step a) until being fully solubilized: c) cooling down the solution of α-sulfo fatty acid salt obtained in the step b) to room temperature gradually to obtain the crystals; d) filtering the crystal obtained in the step c) to remove the motherinsing the filter cake at least twice with acid aqueous solution to obtain the purified α-sulfo fatty acid salt.

    Abstract: An aqueous surfactant composition comprising one or more alpha-sulfo fatty acid disalts (A) of the general formula (I), R1CH(SO3M1)COOM2  (I), wherein 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 amidoalkylbetaines (B) of the general formula (II), R2—CO—NH—(CH2)y—N+(CH3)2—CH2—COO−  (II) in which the radical R2 is a linear or branched alkyl or alkenyl radical with 7 to 19 carbon atoms and the index y is an integer in the range 2 to 4, and water, where specific limiting conditions are to be observed. The compositions are transparent, storage-stable, characterized by good foaming ability and good viscosity, and are suitable for cosmetic products and also detergents and cleaners.
