Aqueous anionic surfactant concentrates containing (a) at least 30% by weight, relative to the aqueous concentrate, of anionic surfactants belonging to the group of water-soluble salts of alkyl aryl sulfonates, alkyl polyglycol ether sulfates, alkyl aryl polyglycol ether sulfates, alkyl polyglycol ether sulfosuccinates, alkyl aryl polyglycol ether sulfosuccinates, alkyl sulfates and alkyl sulfosuccinates, and (b) oleic acid sulfonates, present, compared to concentrates without oleic acid sulfonates, a significantly reduced viscosity for unchanged surfactant action. |
