    Abstract: 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: The present invention is directed to a kappa-2 carrageenan composition comprising: (i) kappa-2 carrageenan, (ii) at least 70% sodium by weight of all cations in the composition; and (iii) free salt present in an amount of 0-25% by weight of the composition; wherein the composition has a viscosity of 20 cps to 40 cps. The present invention is also directed to products made from such kappa-2 carrageenan composition, as well as to processes of manufacture and use thereof.
