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.
Other technological usage
1、Use as remoisten binder, bond for paper and coating bond;
2、Use as thickener for kinds of paints and protectionability colloids;
3、Water-solubility PVP/VA64 series product is the usual emulsifier for plant protect agent and protectionability colloid;
4、The best bond of preparation effervescence troche in hydro-mixture with absolute ethyl alcoholin pharmaceutical area.
