Polyvinylpyrrolidone VA64 Powder EXW Price
CTFAName: VP/VA copolymer
Pharmacopeia Name:Copovidone(Copovidonum)
Chemical Description:Vinylpyrrolidone with Vinyl, Acetate Copolymer
CAS NO: 25086-89-9
Physical Properties: exists as white or milky white powder, and colorless or slight yellow transparent liquid. The clarity of the aqueous solution depends on the proportion of vinylpyrrolidone and vinylacetate.
Product Properties:VP/VA Copolymers with different rations of N-Vinylpyrrolidone to Vinyl ,Acetate,soluble in most organic solvents.Which exists in powder,water solution and ethnol solution form.VP/VA compolymer forms hard,water-removable and glossy films,it has excellent compatibility with many plasticizers and modifiers,an the hydroscopicity decreases in proportion to the ration of Vinyl ,acetate.
Applications:VP/VA Copolymers are the excellent choice as film forming agent and hair-styling agent,which are suitable for fourmulations which used as film forming and viscosity modification,especially in hair styling products, such as Hair Gels,Aerosol gas sprays,Wet look sprays.
