摘要:
Aqueous surfactant compositions containing * one or several disks of alpha-sulfograse acid (A) of the general formula (I), R1CHCSO3M1) COOM2 (I) in which the residue R1 means a linear or branched alkyl or alkenyl residue, with 6 to 18 5 C atoms and residues M1 and M2 - independently from each other - are selected from the group of H, Li, Na, K, Ca / 2, Mg / 2, ammonium and alkanolamines, * one or more acid compounds N-acyl-glutamic (B) of the general formula (II), M3OOC-CH2-CH2-CH (NH-CO-R2) -COOM4 (II) in which the residue R2 means an alkyl or alkenyl residue, linear or branched, with 7 19 C atoms and residues M3 and M4 - independently from each other - selected from the group of H, Li, Na, K, Ca / 2, Mg / 2, ammonium and alkanolamines, * water, in which case The following conditions apply: * 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 to; * provided that the aqueous surfactant compositions contain one or more ester sulphonates (E) of the general formula (V), R5CH (SO3M7) 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 R7 residue can be an alkenyl residue logically only from 3 C atoms, or be branched, and the M7 residue is selected from the group of Li, Na, K, Ca / 2, Mg / 2, ammonium and alkanolamines, it is valid that the compounds (A) have to be present in 50% by weight or more with respect to all the compounds (A) and (E); * the weight ratio of the compounds (B): (A) in the aqueous surfactant compositions is in the range of 2: 1 to 6: 1; * the pH value of the aqueous surfactant compositions is 8 or less; * The average transmission of the aqueous surfactant compositions at 23 ° C - measured with a Turacan MA 2000 - is at least 80%.Composiciones tensioactivas acuosas que conti
