Abstract: To prevent the salting-out of nonionic surfactants from strongly alkaline (pH>9) aqueous solutions, solubilizers have been proposed but existing solubilizers do not have a sufficiently broad action spectrum. The invention seeks to provide solubilizers having a broader action spectrum and provides for this purpose monocarboxylic acids of 6 to 11 carbon atoms optionally in admixture with ene-adducts of maleic anhydride and unsaturated fatty acids of 12 to 24 carbon atoms or their triglycerides. The solutions are useful as cleansers and in the textile industry.
