Anhydrous polysaccharide films

Abstract

This invention relates to anhydrous polymer film compositions containing various polysaccharide ingredients useful for numerous applications. The invention relates to anhydrous liquid compositions that, when dried down, form a film that can release desired ingredients in a controlled and extended-use way. The films can be erodible, partially soluble or completely soluble when used in conjunction with water or water vapor.
