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.
