For professionals in the pharmaceutical industry, selecting the correct excipient is paramount to drug efficacy and stability. Polyvinylpyrrolidone (PVP), a highly versatile non-ionic polymer with CAS 9003-39-8, stands out due to its excellent binding, solubilizing, and stabilizing properties. Understanding the different K grades—such as PVP K15, PVP K17, PVP K25, PVP K30, and PVP K90—is crucial for optimizing formulations. As a leading manufacturer and supplier of PVP in China, we offer comprehensive guidance to help you buy the best product for your needs.

PVP K15 and K17 are generally considered low molecular weight grades. These are often employed as solubilizing agents, helping to improve the solubility of poorly soluble active pharmaceutical ingredients (APIs). They also function effectively as crystallization inhibitors and suspension stabilizers in injectable and ophthalmic formulations. For buyers seeking these specific applications, sourcing pharmaceutical grade PVP K15 or K17 from a reputable China supplier ensures consistent quality and performance.

Medium molecular weight grades, such as PVP K25 and PVP K30, are perhaps the most widely used. Their applications are diverse, including acting as binders in tablets, capsules, and granules, which helps in the mechanical strength of dosage forms. They also serve as stabilizers for oral suspensions, film-forming agents, and dispersants for pigments. If you are looking to buy PVP K30 for tablet binding or PVP K25 as a dispersant, consider the benefits of purchasing from a top China manufacturer known for its stringent quality control.

High molecular weight grades, like PVP K90, are recognized for their exceptional binding capabilities and are often used in oral and topical suspensions as potent stabilizers. Their high viscosity-forming properties also make them ideal as thickeners and hydropylizing agents. When high viscosity is a requirement, such as in specific gel formulations or sustained-release systems, PVP K90 is the preferred choice. For those wanting to purchase PVP K90, understanding its role in achieving desired formulation characteristics is key.
