    Function&Application

    1.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.

    2.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 themolecular. 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.
