Applications:Cosmetics:PVP/VA series products play a good role as film-former and hair-fixing agent. Its hydrophobe decreases with the increase in the proportion of vinyl acetate in the molecular. This property is extremely useful for PVP/VA as hair sprays and hairset lotion. If mix with PVP-K30 can strengthen casehardened effect.

Other Utility:--Binding agent: used in wet granulation processes. --Dry binding agent: used in direct compression tablet processes. --Film coating agent: used for film promoters and sugar coating to prevent splitting,bottom binder to prevent moisture sensitivity. --Crazing agent: acts in taste preparating and coating films
