VA64 CAS 25086-89-9 is a copolymer of vinylpyrrolidone and vinyl acetate. It is a white to milky white powder, easily absorbs moisture, and is soluble in water, ethanol and other organic solvents.
Poly(1-vinylpyrrolidone-co-vinyl acetate), commonly known as Copovidone VA64, is a copolymer of vinylpyrrolidone and vinyl acetate. This high-performance polymer (CAS 25086-89-9) combines the excellent film-forming, adhesive, and solubilizing properties of PVP with the flexibility and compatibility of vinyl acetate.
It is widely used in pharmaceutical, cosmetic, and industrial formulations due to its balanced hydrophilic–hydrophobic characteristics.
We are professional manufacturer of VA64 CAS 25086-89-9 in China, engaged in the R&D, production and sales of VA64. Unilong can supply different grades including industrial and USP26 grades with high quality to meet your application.

Applications of Copovidone VA64
1. Pharmaceutical Applications
Copovidone VA64 (CAS 25086-89-9) is widely used as a binder and film-former in tablet formulations. It enhances tablet stability and drug bioavailability. In solid dispersions, VA64 acts as an efficient solubilizer for poorly soluble drugs, improving dissolution rates.
It is also used in capsule coatings and controlled-release formulations due to its balanced hydrophilicity.
2. Cosmetic and Personal Care
PVP VA Copolymer in cosmetics is valued for its excellent film-forming and styling properties. It is used in hair sprays, gels, and lotions to provide flexible hold and gloss without tackiness. The polymer’s compatibility with other cosmetic ingredients ensures stable and smooth formulations.
3. Industrial Uses
The polymer CAS 25086-89-9 is applied in adhesives, coatings, and inks, offering transparency, flexibility, and superior film adhesion. It serves as a stabilizer and binder in diverse formulations.
VA64 CAS 25086-89-9 is a water-soluble polymer resin with good adhesion, hygroscopicity, film-forming properties and surface activity.
PVP VA64 solubility in water is partial but excellent in ethanol, methanol, and chloroform, making it suitable for solvent-based processes. The polymer forms clear, flexible films and blends well with other polymers, plasticizers, and surfactants.
