Polyvinylpyrrolidone (PVP) is a class of polymers renowned for its versatility, with different grades tailored for specific applications. Among these, PVP K90 is highly sought after for its robust properties. NINGBO INNO PHARMCHEM CO.,LTD. offers high-quality PVP K90, and understanding its various grades is key to optimizing formulation success in cosmetics and pharmaceuticals.

The 'K' value in PVP K90 refers to its viscosity, which is directly related to its molecular weight. Generally, a higher K value indicates a higher molecular weight and thus increased viscosity. PVP K90, with its high K value, possesses significantly higher molecular weight and viscosity compared to lower grades like PVP K30 or K15. This higher molecular weight translates into stronger film formation, enhanced adhesive properties, and greater thickening capabilities.

In cosmetic applications, the choice between PVP K90 and other grades often depends on the desired hold and texture. For hair styling products requiring a strong, long-lasting hold, PVP K90 is often preferred due to its superior film-forming and cohesive strength. Its transparency and ability to create a smooth film also contribute to a polished appearance. In skincare, the higher molecular weight can contribute to a richer texture and improved moisture retention.

In the pharmaceutical realm, PVP K90's high molecular weight makes it an excellent binder for tablets, offering superior tablet hardness and integrity. It is also highly effective in improving the solubility and bioavailability of poorly soluble drugs, a crucial factor in drug efficacy. Its strong stabilizing properties are beneficial for sensitive APIs, extending product shelf-life and maintaining potency. The selection of PVP K90 over lower molecular weight grades is often driven by the need for enhanced binding strength, viscosity modification, and improved drug dissolution rates.

NINGBO INNO PHARMCHEM CO.,LTD. emphasizes the importance of selecting the appropriate PVP K90 grade based on the specific requirements of the formulation. By understanding the relationship between K value, molecular weight, viscosity, and application performance, formulators can leverage the unique advantages of PVP K90 to create innovative and highly effective products. Our commitment to quality ensures that manufacturers have access to reliable grades of PVP K90 for their diverse product development needs.
