ABSTRACT OF THE DISCLOSURE C8-C40 alcohols, optionally containing one or more hydroxyl groups and onto which up to 20 moles of ethy- lene oxide and/or propylene oxide can be added per mole of alcohol, when added to aqueous industrial anionic surfactant concentrates, particularly concentrates of ?-sulfofatty acid esters containing at least 50% by weight of the sodium salt of ?-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 surfac- tant, whereupon the viscosity of the surfactant con- centrate becomes at most 10,000 mPas at 70°C.
