Copovidone, an analog of povidone, is used as a tablet binder, a film-former, and as part of the matrix material used in controlled-release formulations. In tableting, copovidone can be used as a binder for direct compression and as a binder in wet granulation. Copovidone is often added to coating solutions as a film-forming agent. It provides good adhesion, elasticity, and hardness, and can be used as a moisture barrier.
Copovidone has better plasticity than povidone as a tablet binder, is less hygroscopic, more elastic, and better for film-forming applications than povidone. Copovidone is also used in cosmetics as a thickener, dispersant, lubricant, film-forming agent and binder. It is widely used in the food, cosmetic and pharmaceutical industry.
