ABSTRACT:
A method is provided for making a water soluble powdered formulation including a water-insoluble or difficultly-water-soluble chromogenic agent therein. The method includes first melting a water-soluble or water-miscible, heat-stable, polymeric material, e.g., PEG. The water-insoluble or difficultly-water-soluble chromogenic agent is then dissolved in such molten polymeric material. The molten polymeric material and the dissolved chromogenic agent are heated together for a predetermined period of time to provide a molten homogenate. The molten homogenate is then cooled to its solidification temperature to provide a solid homogenate. Finally, the cooled solid homogenate is pulverized to powdered form.
