VP/VA Copolymers are the excellent choice as film forming agent and hair-styling agent,which are suitable for fourmulations which used as film forming and viscosity modification,especially in hair styling products, such as Hair Gels,Aerosol gas sprays,Wet look sprays.
Copovidone 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.
