PVP/Vas series products play a good role as film-former and hair-fixing agent. Its hygroscopicity decreases with the increase in the proportion of vinylacetate in the molecular. This property is extremely useful for PVP/VA as hair sprays and hairset lotion. If being used with PVPK30, the effect would be enhanced.
