U.S. Patent 9248146
Publication date: Feb. 2, 2016
Assignee: Adhesives Research, Inc.

This patent disclosure relates to adhesive films containing a mixture of high molecular weight and low molecular weight water-soluble components, and a pharmaceutically or cosmetically active ingredient. Optionally, the films contain a starch component, a polysaccharide component, a filler, a plasticizer and/or humectant.

The films are in the form of an adhesive layer and have a thickness sufficient to disintegrate when exposed to a moist environment and/or a trigger compound, thereby releasing the active. The films can be cut to any size or shape to provide convenient dosage forms for administration. While a surfactant is optional in certain embodiments of this invention, other embodiments are surfactant-free or substantially surfactant-free.
