vp/va copolymer PVP-S630
-----------------------------------------------------------------------------------------------
CTFAName: PVP/VA 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.
Cosmetic Grade VP/VA Copolymers
CAS:25086-89-9 PVP VA64/PVP S630
Product Name:VP/VA Copolymers
Chemical Description:Vinylpyrrolidone with Vinyl Acetate Copolymer
INCI/CTFA:VP/VA Copolymer
CAS NO.:25086-89-9
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.
