Abstract
The invention provides a dispersion having an oily phase, an aqueous phase, in the form of an oil-in-water emulsion or a water-in-oil emulsion, and at least one active ingredient that is only slightly or with difficulty soluble in the oily phase and the aqueous phase. The dispersion is free from toxicologically dangerous organic solvents. The dispersion contains the active ingredient dissolved in a quantity that is greater than the quantity which results additively from its maximum solubility in the oily and the aqueous phase of the emulsion prior to forming the emulsion.
