Abstract
Polysaccharide-based shells are provided having use for forming water-dispersible microcapsular delivery systems for both hydrophilic and lipophilic drugs, pharmaceuticals, cosmetics and other active agents. These shells are prepared by intimately blending a solubilized polysaccharide with a lipophilic material to produce spherical droplets of the lipophilic material coated with the polysaccharide, diluting the emulsion with a solvent, and isolating the polysaccharide shells from the diluted emulsion.
Claims19
A composition consisting of discrete spherical shell and optionally material encased in said shell selected from the group consisting of lipophilic material and bioactive material, wherein the structural component of said shell consists essentially of non-cross-linked jet-cooked starch.
