Abstract

A water dispersible film-forming particulate composition for use in coating pharmaceuticals and foods or the like, produced by freeze-drying an aqueous solution of a water-soluble polymer, a plasticizer, and optionally a pigment, is described. The product mixes readily with water to form an aqueous dispersion which is applied in the conventional manner to solid pharmaceutical forms.
