NINGBO INNO PHARMCHEM CO.,LTD. is pleased to present its high-quality range of Povidone PVP K series, identified by the CAS number 9003-39-8. This versatile polymer, Polyvinylpyrrolidone, is a cornerstone ingredient in numerous applications, particularly within the pharmaceutical, cosmetic, and various industrial sectors. Available in powder form, our Povidone PVP K series offers distinct characteristics based on its K-value, corresponding to different molecular weights and viscosities, making it suitable for a wide array of formulations.

The Povidone PVP K series is synthesized through the polymerization of N-vinylpyrrolidone. Its unique properties, including excellent solubility in both water and organic solvents, chemical inertness, non-toxicity, and good film-forming capabilities, contribute to its extensive utility. The different K-values denote varying degrees of polymerization, directly influencing the molecular weight and rheological properties of the resulting polymer. This allows formulators to select the precise grade required for optimal performance in their specific application.

Key grades available include Povidone K15, K17, K25, K30, K60, K90, and K120. Each grade possesses distinct functional roles. For instance, lower molecular weight grades like K15 and K17 are often utilized as dispersants, cosolvents, or crystallization inhibitors in liquid formulations. As the K-value increases, the viscosity and adhesive properties become more pronounced. Povidone K25 and K30 are widely recognized as efficient stabilizers for oral and topical suspensions. They serve as effective adhesives for tablets, function as pore-forming agents, and act as thickeners in various systems.

The higher molecular weight grades, such as Povidone K90, are particularly valued as robust binders for solid dosage forms like tablets, granules, and capsules. Their strong adhesive properties ensure the integrity and cohesion of the final product. Additionally, Povidone K90 functions as a stabilizer and solubilizer for oral suspensions and acts as a dispersant, film-forming agent, and promoter in diverse pharmaceutical formulations. The adaptability across the K series underscores its importance as a premier pharmaceutical excipient, working effectively in over one hundred different drug formulations to improve stability, bioavailability, and ease of manufacturing.

Beyond pharmaceuticals, the Povidone PVP K series is an indispensable component in the cosmetics industry. Here, it performs multiple roles, including acting as a film-forming agent to provide hold in hair sprays, mousses, gels, and lotions. It enhances viscosity, acts as a lubricator, and serves as an adhesive in hair care products, hair-dying reagents, and shampoos. Furthermore, it is used as an assistant in skin-care products, eye makeup, lipstick, deodorants, sunscreens, and dentifrice, contributing to product texture, stability, and performance.

The utility of Povidone PVP K series extends to numerous other industrial applications. It is employed as an assistant in areas such as paints and coatings, plastics and resins, adhesives, glass fiber production, film manufacturing, ink formulations, TV tube production, detergents, biocides, tabulating processes, and textile dyeing and printing. Its broad compatibility and functional versatility make it a valuable additive across these diverse fields.
