Described is a fragrance control release system which is an emulsifier-free, single phase, nonporous, continuous, permeable polymeric film having a substantially uniform thickness of from about 1 up to about 150 microns, having entrapped and dissolved therein molecules of at least one fragrance subs
Described is a fragrance control release system which is an emulsifier-free, single phase, nonporous, continuous, permeable polymeric film having a substantially uniform thickness of from about 1 up to about 150 microns, having entrapped and dissolved therein molecules of at least one fragrance substance capable of evolving from said film into the environment proximate said film by means of molecular diffusion at a permeation rate of from about 1×10-7up to about 0.1 mg-mm/cm2-min in a sustained and controlled release manner. Also described is a process for using the aforementioned system for imparting a fragrance into the environment above the unobstructed outer surface of the aforementioned polymer film which is coated on the surface of a solid or semi-solid support, e.g., a woven or non-woven fabric substrate; or a solid surface or human epidermis.
