Application:
Pharmaceuticals: It is mainly used as water soluble and drying adhesive agent when making grain and pressing tablet directly. It will be used in film coating and cover-taste agent. It can prevent sugar coating from split and make bottom coating avoid dampness.
Cosmetics: PVP/VA Series play a good role in film-former and hair-fixing agent. Its hygroscopicity decreases with the increase of the proportion of vinylacetate in the molecular. This property of PVP/VA is extremely useful as it works in hair sprays and hair-set lotion. If it is mixed with PVP K-30, the effect of hair-fixing would be changed a lot.
Other Utility: PVP/VA series can be used in remoistenable adhesive and other adhesives for paper or viscosity-enchancing agent and protecting colloid for printing ink. PVP/VA 64 series can also act as emulsifying agent, protecting colloid for planting-protecting chemicals, other dispersing systems and binder in coating.
