NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing in-depth insights into the science behind our high-quality ingredients, including Polyvinylpyrrolidone K90 (PVP K90). The exceptional film-forming and solubility-enhancing properties of PVP K90 are rooted in its unique polymer structure and its interaction with solvents and active ingredients. Understanding these scientific principles is key to harnessing its full potential across diverse applications.

The film-forming capability of PVP K90 is attributed to its hydrophilic nature and its ability to arrange itself at interfaces. When applied to a surface, such as skin or hair, the polymer chains orient themselves to create a continuous, flexible, and often glossy film upon solvent evaporation. This property is extensively utilized in hair styling products for hold and shine, and in cosmetics for creating protective barriers on the skin. The resultant films are typically clear, tough, and can be easily removed, making PVP K90 a preferred choice for many formulations.

Furthermore, PVP K90's efficacy as a solubility enhancer, particularly for poorly soluble drugs, is a critical advancement in pharmaceutical science. Its ability to form amorphous solid dispersions with hydrophobic APIs disrupts the crystalline structure of the drug. This increases the surface area available for dissolution and enhances the rate at which the drug dissolves in biological fluids, leading to improved bioavailability. The interaction is primarily driven by hydrogen bonding and van der Waals forces between the polymer and the drug molecule. The PVP K90 film former and PVP K90 solubility enhancer attributes are a testament to its advanced chemical design. NINGBO INNO PHARMCHEM CO.,LTD. ensures that our PVP K90 meets the highest standards for these scientific applications, enabling innovation in product development.
