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.
