Abstract:
Method of loading a dispersion with at least an active- or effect material, which is insoluble in the coherent phase of the dispersion, comprises allocating and contacting the dispersion and a solution of the active- or effect material in a solvent, which is at least partially miscible with the coherent phase of the dispersion. An independent claim is included for the active- or effect material.
