NINGBO INNO PHARMCHEM CO.,LTD. is a trusted supplier of advanced chemical materials, and our PVP/VA 64 copolymer, or Copovidone, is a prime example of a highly functional ingredient with broad utility. Understanding its chemical properties is key to unlocking its full potential in various industries.

The PVP/VA 64 copolymer is a synthetic random copolymer created from the polymerization of N-vinylpyrrolidone (NVP) and vinyl acetate (VA) in a specific ratio, typically 60:40 by weight. This ratio is critical to its performance, influencing its solubility, film-forming capabilities, and binding strengths. The synthesis, often based on the Reppe process adapted for copolymerization, results in a white to off-white powder with a faint characteristic odor. Its chemical formula is approximately (C6H9NO)n(C4H6O2)m, where 'n' and 'm' represent the molar ratios of the monomers.

A key feature of this vinylpyrrolidone vinyl acetate copolymer is its solubility. It readily dissolves in most hydrophilic solvents, including water, ethanol, and isopropanol, making it highly adaptable for various formulation processes. While it exhibits good solubility, the vinyl acetate component makes it slightly less hydrophilic than homopolymer povidone, which can be advantageous for controlling water sensitivity and improving film properties.

The diverse copovidone pharmaceutical excipient applications stem directly from these properties. As a binder, it facilitates tablet formation; as a film-former, it protects and enhances coatings; and as a matrix former, it aids in drug delivery systems like solid dispersions. In the cosmetic industry, it functions as a styling agent and film-former for hair products.

The PVP VA 64 copolymer binder aspect is well-documented, demonstrating strong bonding capabilities essential for tablet integrity. Its use as a film forming agent in cosmetics ensures desirable hold and texture in styling products.

NINGBO INNO PHARMCHEM CO.,LTD. ensures that when you buy PVP/VA 64 from us, you receive a product with consistent quality and well-defined chemical characteristics, suitable for demanding pharmaceutical and cosmetic applications. Our commitment to quality ensures that this versatile copolymer continues to be a vital component in product innovation.
