Poly(1-vinylpyrrolidone-co-vinyl acetate) is widely used in the pharmaceutical industry as a binder in tablet formulations, ensuring the active ingredients are held together effectively. It also acts as a solubilizer for poorly water-soluble drugs and a film-forming agent in coatings for pills, providing a smooth and protective layer that enhances stability and controlled release. In the cosmetics sector, it serves as a stabilizer and thickener in lotions, creams, and hair care products, improving texture and consistency. Additionally, it is utilized in adhesives and paints due to its excellent film-forming and binding properties, contributing to durability and performance. Its biocompatibility and solubility in water make it a versatile material in various industrial applications.
