AI Product Description
*The following content is generated by AI and is for reference only.
PVP K30 and PVP K90 are high-performance polyvinylpyrrolidone grades widely utilized across pharmaceutical, cosmetic, and industrial sectors. Chemically, both share the identical molecular formula (C₆H₉NO)ₙ and a CAS number of 9003-39-8. The distinction between K30 and K90 lies primarily in their viscosity and molecular weight distribution, which dictates their specific functional applications.
PVP K30 features a lower molecular weight with an average viscosity of approximately 25 to 35 cP in a 4% solution. This characteristic makes it ideal for applications requiring rapid dissolution and high solubility. In the pharmaceutical industry, K30 is frequently employed as a binder in tablet formulation, ensuring granule integrity during compression while maintaining excellent disintegration properties. It also serves as a stabilizer in liquid suspensions and a protective colloid in ophthalmic solutions. Furthermore, its ability to form clear films without yellowing makes it a preferred choice for hair care products, where it provides hold without stiffness or stickiness.
Conversely, PVP K90 possesses a significantly higher molecular weight and viscosity, ranging from 160 to 220 cP in a 4% solution. Due to its robust film-forming capabilities and superior binding strength, K90 is extensively used in coatings, adhesives, and ink formulations. In pharmaceutical contexts, it acts as a controlled-release agent, helping to modulate drug release rates by forming dense polymer matrices. It is also crucial in the production of contact lenses and medical devices where mechanical strength and biocompatibility are paramount. Additionally, K90 enhances the stability of pigments in printing inks and paints, preventing aggregation and sedimentation over time.
Both grades are non-toxic, non-irritating, and fully water-soluble, adhering to strict regulatory standards such as USP/NF and EP. Their versatility stems from their unique amphiphilic nature, allowing them to interact effectively with various organic and inorganic substances. Whether optimizing tablet hardness, enhancing hair styling performance, or stabilizing complex industrial dispersions, PVP K30 and K90 remain indispensable polymers driving innovation in material science and product development globally.
