Technical 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.
