摘要:
Aqueous surfactant compositions containing * one or several disks of alpha-sulfo fatty acid (A) of the general formula (I), R1CH (SO3M1) COOM2 (I) in which the residue R1 means an alkyl or alkenyl residue, linear or branched, with 6 to 18 C atoms and residues M1 and M2 - independently of each other - are selected from the group of 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) and -N + (CH3) 2-CH2-COO- (II) in which the residue R2 means an alkyl or alkenyl residue, linear or branched, with 7 to 19 C atoms and the index and is an integer in the range of 2 to 4, * water, in which the following conditions apply: * with respect to compounds (A) it is applied that the fraction of the compounds (A) in which the R1 residue is an alkenyl residue, is 3% by weight or less, based on the total amount of the compounds (A) in the surfactant compositions s watery; * with respect to the compounds (B) it is applied that the fraction of the compounds (B), in which the residue R2 is an alkenyl residue, is 3% by weight or less, with respect to the total amount of the compounds (B) in the aqueous surfactant compositions; * the content of the compounds (A) and (B) in the aqueous surfactant compositions is at least 5% by weight, with respect to the entire aqueous surfactant composition; * if the aqueous surfactant compositions contain one or more estersulfonates (E) of the general formula (V), R5CH (SO3M5) COOR6 (V) in which the residue R5 means a linear or branched alkyl or alkenyl residue, with 6 to 18 C atoms and the R6 residue means an alkyl or alkenyl residue, linear or branched, with 1 to 20 C atoms, in which case the R6 residue only from 3 C atoms can logically be an alkenyl residue or can be branched, and the M5 residue is selected from the group of Li, Na, K, Ca / 2, Mg / 2, ammonium and alkanolamines, it is applied that the compounds (A) have to be present in 50% or more, with respect to
