Abstract: Embodiments of the invention are directed toward devices for emitting a volatile substance, and associated methods of producing such devices. In one embodiment, the delivery device for a volatile substance includes an active layer that is created from a dried polymer solution that contains the volatile substance. A release liner is in direct contact with the active layer, and covers a side of the active layer. The polymer solution may include thickeners, plasticizers, dyes, and preservatives. The devices may deliver volatile substances such as fragrances, masking odors, or therapeutic agents. Some embodiments of the invention are directed toward a patch by positioning a barrier layer on the active layer; the barrier layer may adhere to a surface, and isolate the surface from the active layer. Other embodiments are directed toward controlling the rate of delivery of the volatile agents from patches and other volatile delivery devices.

Abstract: Compositions and methods for delivering active agents to the skin of a subject, including a polymer, an active ingredient and a solvent are disclosed, the compositions being capable of delivery by rolling, spreading, aerosol or in droplets and of forming a film in contact with the skin.
