ABSTRACT:
An improved wet powder, edible, film-forming composition for use in coating tablets and capsules consists essentially of powdered pigment particles, a film-forming, water soluble or water-dispersible, edible polymer and up to approximately 30% by weight of water. Such compositions are formed by blending the pigment particles and the polymer and applying the water onto the pigment-polymer blend in atomized form. Similar wet powder, edible, clear, film-forming compositions for use in coating tablets and capsules with a clear coating consist essentially of a film-forming, water soluble or water-dispersible, clear, edible polymer and up to approximately 30% by weight of water and are formed by applying the water onto the polymer in atomized form. The application of water in this manner preconditions the polymer and permits the preparation of smooth stable coating suspensions upon dilution with additional water and without the formation of fish eyes.
