CTFA name:VP/VA Copolymer
CAS No:25086-89-9
Molecular formula:(C6H9ON)n×(C4H6O2)m (n=1.2m)
Character:PVP/VA is a kind of water-solubility macromolecule resin, white powder or transparent liquor, no smell,
not absorption of moisture, can dissolve in water-ethanol and anhydrous alcohols, has good cohesiveness, hygroscopic,
film forming and surface activity character.
Application(VP/ VA) (VA73E,VA73W,VA64E,VA64W,VA55E)
Beauties industry:PVP-VA series use as stiffener, its hygroscopic decrease as the ratio of vinyl acetate
increase,it suits for Mousse, hair casehardened liquid, if mix with PVP-K30 can
strengthen casehardened effect.
