Abstract of the Disclosure The present invention is directed to a process for making homogeneous, thermoreversible gel films comprising the steps of: (i) heating, hydrating, mixing, solubilizing, and, optionally, de-aerating a high solids, low moisture film forming composition in an apparatus providing sufficient shear, temperature and residence time to form a homogeneous molten composition, wherein the temperature is at or above the solubilizing temperature of said composition; (ii) feeding the molten composition into at least one of a mixer, pump or devolatilizer; and (iii) cooling the homogeneous molten composition at or below its gelling temperature to form said gel films. The present invention is also directed to various products made from such films, such as the gel films themselves, soft capsules, solid dosage forms and delivery systems.

Abstract:
Ultra-fine microcrystalline cellulose compositions are disclosed which comprise co-attrited microcrystalline cellulose and a hydrocolloid. The compositions have a mean particle size of less thin 10 microns. The compositions are prepared by subjecting a high solids mixture of microcrystalline cellulose and a hydrocolloid to high shear forces in the presence of an anti slip agent preferably an aqueoussolution of an inorganic salt. The compositions arc especially useful in food pharmaceutical and cosmedic and industrial applications.
