The invention proposes high-concentration flowable aqueous anionic surfactant mixtures having a solids content in the range from 50 to 80% by weight, comprising - based on the surfactant content (a) 60 to 90% by weight of alkyl ether sulfates of the formula (I), R10 (CH2CH2O)n SO3X1 (I) in which R1 is a linear or branched alkyl radical having 12 to 22 carbon atoms, n is a number from 1 to 10, and X1 is alkali metal, alkaline earth metal, ammonium, alkylammonium, alkanolammonium or glucammonium, and (b) 10 to 40% of weight of alkyl sulfates of the formula (II), (II) in which R2 is a linear or branched alkyl radical having 12 to 22 carbon atoms, and X2 is alkali metal, alkaline earth metal, ammonium, alkyl-ammonium, alkanolammonium or glucammonium, with the proviso that the amounts, optionally with further surfactants, total 100% by weight. |
