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.

Abstract: The invention is directed to cationic surfactants of formula (I), where R1 is a saturated or unsaturated, branched or linear alkyl group having 6 to 22 carbon atoms, R2 and R3 independently are C1-C3 alkyl groups or hydrogen, n is 2 or 3, and X? is an anion selected from the group consisting of halides, deprotonated carboxylic acids and methosulfate. The cationic surfactants are useful, particularly as hair conditioners, for the preparation of cosmetic compositions.
