ABSTRACT OF THE DISCLOSURE Alkali metal alkane sulfonates containing on averge 11 to 21 carbon atoms are used as viscosity regulators for aqueous, highly concentrated commercial anionic surfactant concentrates, more especially for .alpha.-sulfofatty acid ester salt concentrates containing at least 30% by weight of .alpha.-sulfofatty acid ester salt. The viscosity regulators are used in quantities of from 0.5 to 10% by weight, based on the surfactant content, so that the concentrates have a viscosity at 40°C of at most 10,000 mPas.
