NINGBO INNO PHARMCHEM CO.,LTD. specializes in high-quality chemical raw materials, including a range of copovidone products. Among these, Copovidone VA64 and VA73 are prominent grades, each offering specific properties beneficial for diverse applications. Understanding the nuances between these grades is key to optimizing formulations in pharmaceuticals and other industries.

Copovidone itself is a copolymer of N-vinyl-2-pyrrolidone and vinyl acetate. The VA64 and VA73 designations typically refer to the ratio of these monomers, influencing characteristics like solubility, hygroscopicity, and glass transition temperature. For instance, VA64 is known for its excellent film-forming and binding capabilities, making it a prime choice for applications where good plasticity is required. The fact that it is copovidone less hygroscopic than povidone is a significant advantage for formulation stability.

In the pharmaceutical sector, both grades are widely used. Copovidone VA64 is particularly favored as a copovidone VA64 binder for tablets due to its superior adhesion and compressibility properties. It is also instrumental in creating amorphous solid dispersions, enhancing the solubility of poorly water-soluble drugs. The ability to use it in techniques like melt extrusion and spray drying highlights its processing versatility. Similarly, copovidone VA73 offers comparable benefits, often tailored for specific binding or film-forming needs where slight variations in monomer ratios are beneficial.

The utility of copovidone extends beyond pharmaceuticals. As a copovidone for hair fixing agent, it is valued in the cosmetic industry for its ability to provide hold and structure to hair styling products. Its film-forming properties contribute to the performance and aesthetic of these formulations. When manufacturers look to buy copovidone for cosmetics, they often seek grades that offer good solubility and compatibility with other cosmetic ingredients.

NINGBO INNO PHARMCHEM CO.,LTD., as a dedicated copovidone supplier in China, ensures that our VA64 and VA73 grades meet stringent quality benchmarks, including GMP and DMF certifications for pharmaceutical applications. This commitment to quality means our clients can confidently select the appropriate grade for their specific needs. The comprehensive understanding of copovidone solubility and applications allows us to support our customers effectively.

Choosing between VA64 and VA73 might depend on the specific performance requirements of the formulation. However, both represent high-quality copovidone options that can significantly improve product performance, whether in a pharmaceutical tablet or a cosmetic hair spray. Their well-established benefits make them indispensable excipients.
