NINGBO INNO PHARMCHEM CO.,LTD. is proud to offer high-quality VP/VA Copolymers and Copovidone, versatile polymers renowned for their exceptional performance in both pharmaceutical and cosmetic applications. Known generically as Vinylpyrrolidone with Vinyl Acetate Copolymer, these materials serve as critical excipients and active ingredients, providing essential functional properties to a wide array of products.

VP/VA Copolymers are synthesized through the copolymerization of N-Vinylpyrrolidone and Vinyl Acetate monomers. By controlling the ratio of these monomers, polymers with varying properties can be created, allowing for tailored performance characteristics. This flexibility makes VP/VA Copolymers indispensable in diverse formulations, particularly where film formation, binding, and solubility are key requirements.

In the pharmaceutical industry, the copolymer with a specific vinylpyrrolidone to vinyl acetate ratio (typically 6:4), known pharmacopeially as Copovidone (Copovidonum) or PVP/VA 64, is a highly valued excipient. Copovidone is a white or creamy white, free-flowing powder with a characteristic smell, known for its hygroscopic nature. Its excellent solubility in water, alcohol, and other organic solvents makes it incredibly adaptable for various formulation processes. Copovidone is primarily utilized as a versatile binder in tablet manufacturing. It performs exceptionally well in both wet and direct granulation processes, enhancing the compressibility and flow properties of powder blends, leading to the production of robust tablets with good mechanical strength. Furthermore, Copovidone serves as an effective film-forming material for tablet coating. These coatings can improve the tablet's appearance, mask unpleasant tastes or odors, protect the active pharmaceutical ingredient from moisture and light, and facilitate easier swallowing.

Beyond binding and coating, Copovidone's film-forming properties also make it suitable for other pharmaceutical applications, including use in solid dispersion formulations to enhance the solubility and bioavailability of poorly soluble drugs. Its regulatory acceptance across major pharmacopeias, such as USP, EP, and BP, underscores its established safety and efficacy profile for pharmaceutical use. NINGBO INNO PHARMCHEM CO.,LTD. ensures that its Copovidone product meets these stringent international standards, providing pharmaceutical manufacturers with a reliable and compliant material.

The cosmetic industry also extensively utilizes VP/VA Copolymers, often referred to by their INCI/CTFA name, VP/VA Copolymer. Available in various forms, including powder, water solutions, and ethanol solutions, these copolymers are celebrated for their superior film-forming capabilities. They are particularly effective in hair styling products such as hair gels, aerosol and non-aerosol hair sprays, and wet look sprays, where they provide strong, durable hold without excessive stiffness. The films formed by VP/VA Copolymers are typically hard yet water-removable, a desirable trait in many personal care formulations. Their excellent compatibility with a wide range of plasticizers and other modifiers allows formulators to achieve desired film flexibility and properties.

The versatility of VP/VA Copolymers in cosmetics extends beyond hair styling. They can act as viscosity modifiers, emulsifiers, and suspending agents in various cosmetic formulations, contributing to product stability and texture. Their ability to form glossy films also makes them useful in nail care products and certain skin applications.

NINGBO INNO PHARMCHEM CO.,LTD. supplies VP/VA Copolymers and Copovidone that exhibit the key properties essential for these demanding applications: good solubility in relevant solvents, excellent adhesion, strong film-forming capacity, and compatibility with common formulation ingredients.
