Pharmaceutical Grade PVP K90, supplied by NINGBO INNO PHARMCHEM CO., LTD., is a synthetic polymer known for its unique chemical structure and versatile properties. Its backbone consists of repeating N-vinylpyrrolidone units, contributing to its water solubility, hygroscopicity, and excellent film-forming capabilities. The K-value, a measure of its molecular weight, is crucial in determining its suitability for specific applications, with K90 representing a higher molecular weight grade. This higher molecular weight translates to enhanced binding strength and viscosity-building properties, making it ideal for applications like tablet granulation and suspension stabilization.

The solubility profile of PVP K90 is extensive, dissolving readily in water, ethanol, and other polar organic solvents like isopropyl alcohol and trichloromethane, while remaining insoluble in non-polar solvents such as acetone and ether. This broad solubility range allows for flexible formulation strategies. NINGBO INNO PHARMCHEM CO., LTD. ensures that their PVP K90 meets stringent international pharmacopoeia standards (USP, BP, EP), guaranteeing low levels of impurities such as residual 2-pyrrolidone and vinylpyrrolidinone, as well as controlled levels of water and ash residue. This commitment to quality is vital for pharmaceutical use.

Beyond its primary roles as a binder, disintegrant, and suspending agent, PVP K90 finds applications in drug delivery systems, acting as a stabilizer for nanoparticles and microparticles, and in enhancing the solubility of poorly permeable drugs. For companies looking to buy PVP K90, NINGBO INNO PHARMCHEM CO., LTD. offers a reliable source with competitive pricing and comprehensive technical support. Understanding these chemical properties and application potentials allows manufacturers to fully leverage the benefits of this indispensable pharmaceutical excipient in their product development endeavors.
