Abstract

The flow behavior of aqueous surfactant concentrates containing at least 20 wt. % of water-soluble salts of alkylpolyglycolether sulfosuccinates and/or alkylarylpolyglycolether sulfosuccinates is improved by adding to these concentrates at least one of the following viscosity regulators: a lower polyalkyleneether glycol having a molecular weight of at least about 1500; a water-soluble salt of a monosulfosuccinate of a lower polyalkyleneether glycol having a molecular weight of at least about 600; and a water-soluble salt of a disulfosuccinate of a lower polyalkyleneether glycol having a molecular weight of at least about 600.
