2114952 9303128 PCTABS00019 The aim of the invention is to the improve the flow behaviour and pumpability of highly concentrated aqueous alkyl sulphate slurries, in particular at low temperatures and low shear gradients. This is achieved essentially by mixing the aqueous slurry from 50 to 80 % by wt. of an alkyl sulphate of the formula R1-O-SO3M1, in which R1 is a straight-chain or branched-chain alkyl group with 12 to 22 C-atoms and M1 is an alkali-metal, ammonium, alkylammonium or hydroxyalkylammonium ion, and an alkenyl sulphate of the formula R2-O-SO3M2, in which R2 is an alkenyl group with 16 to 22 C-atoms and 1, 2 or 3 double bonds and M2 is an alkali-metal, ammonium, alkylammonium or hydroxyalkylammonium ion, in the proportions of alkyl sulphate to alkenyl sulphate of 10:1 to 1:3.
