ABSTRACT:
C.sub.8 -C.sub.40 Alcohols, or C.sub.8 -.sub.C 40 alcohol containing one or more hydroxyl groups and onto which up to 20 moles of ethylene oxide and/or propylene oxide can be added per mole of alcohol, when added to aqueous industrial anionic surfactant concentrates, particularly concentrates of .alpha.-sulfofatty acid esters containing at least 50% by weight of the sodium salt of .alpha.-sulfofatty acid ester, significantly improve the rheological behavior thereof. The alcohols are added in quantities of from about 1 to about 15% by weight, based on the quantity of surfactant, whereupon the viscosity of the surfactant concentrate becomes at most 10,000 mPas at 70.degree. C.
