Cosmetic Grade VP/VA Copolymers
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.
