Abstract
A thixatropic gelatin carrier composition which is used as a vehicle in the manufacture of soft or hard gelatin capsule. The composition comprises from about 84% to 95% of a vegetable oil, from about 1% to 9% of a viscosity modifier and from about 1% to 15% of a surface active agent. When the carrier composition is stirred it becomes fluid and active solids are dispersed in the carrier during stirring. When the stirring is stopped, the carrier becomes a semi-solid and maintains the active solids in a stable uniform dispersion. Up to about 50% by weight of active solids can be dispersed in the carrier composition and the active solids can include vitamins, pharmaceuticals or nutriceuticals or combinations thereof.
