Water-dispersible polymeric compositions

摘要

Disclosed is a process for preparing polymeric compositions which are suitable for coating medicaments or for use in cosmetic formulations and the novel compositions prepared therefrom. The process makes stable, colloidal, latex-like dispersions of coating polymers which can be readily dried to form polymeric powder materials. The process makes use of a novel combination of a water-in-oil emulsifier and an oil-in-water emulsifier.
