Polyvinylpyrrolidone (PVP) is classified and differentiated by its K-value, a measure directly related to its molecular weight and viscosity. Understanding these K-values is crucial for selecting the appropriate PVP grade for specific applications. NINGBO INNO PHARMCHEM CO.,LTD. offers a comprehensive range of PVP polymers, with a particular focus on PVP K15, explaining its unique benefits derived from its K-value.

The K-value of PVP is determined by the relative viscosity of its aqueous solution. A higher K-value generally indicates a higher molecular weight and thus increased viscosity and adhesive strength. PVP K15, typically having a K-value between 12.75 and 17.25, represents a low to medium molecular weight grade. This specific molecular weight range is strategically important for several applications. The PVP K15 solubility properties are excellent, making it highly effective as a solubilizing agent for poorly soluble compounds, thereby enhancing their absorption and efficacy.

For pharmaceutical formulations, the PVP K15 solubility improver characteristic is invaluable. It aids in dissolving APIs that might otherwise be difficult to formulate, leading to more stable and effective liquid preparations and injections. In cosmetic applications, this K-value contributes to optimal film formation and texture modification, providing desirable hold in hair products and smooth application in skin care. The PVP K15 formulation performance is directly linked to this balanced molecular weight.

NINGBO INNO PHARMCHEM CO.,LTD. provides detailed specifications for our PVP K15, allowing formulators to precisely match the product's K-value to their application needs. Whether it's for tablet binding, suspension stabilization, or enhancing cosmetic product feel, the choice of K15 offers a unique balance of viscosity, solubility, and adhesive properties. By understanding how the K-value impacts these characteristics, formulators can confidently buy PVP K15 from us for optimized product development.

Choosing the right PVP K value is a critical step in product formulation. Our expertise at NINGBO INNO PHARMCHEM CO.,LTD. ensures that you receive the most suitable PVP K15 to meet your precise requirements, guaranteeing superior performance and reliability in your end products.
