NINGBO INNO PHARMCHEM CO.,LTD. is pleased to announce the availability of high-quality Polyvinylpyrrolidone (PVP), also known as Povidone, available in various K-value grades from K12 to K120. With the CAS number 9003-39-8, this versatile polymer is supplied in a fine powder form, known for its exceptional properties and broad range of applications across numerous industries.

Polyvinylpyrrolidone is a water-soluble synthetic polymer made from the monomer N-vinylpyrrolidone. Its solubility in water, alcohol, amines, and many other organic solvents makes it incredibly useful. This property, combined with its excellent biocompatibility and physiological inertness, positions PVP as a preferred material in sensitive applications such as pharmaceuticals and cosmetics. The polymer is non-toxic and well-tolerated by the body, which is crucial for its use in drug formulations and personal care products.

One of the most notable characteristics of PVP is its strong film-forming capability. When dissolved and applied, it dries to form a clear, glossy film. This film is adhesive and protective, making PVP an ideal binder, coating agent, and film former. Its ability to form stable complexes with a wide variety of organic and inorganic compounds further enhances its utility, allowing it to act as a dispersant, suspension stabilizer, and solubilizer.

The different grades of PVP are distinguished by their K-value, which relates to the average molecular weight and, consequently, the viscosity of its aqueous solutions. Lower K-values (like K12, K15, K17) correspond to lower molecular weights and viscosities, making them suitable for applications requiring good solubility and wetting properties, such as solubilizers and dispersants in oral liquids or injectables. Intermediate K-values (K25, K30) are widely used as binders in tablets and granules, film-forming agents in coatings, and stabilizers in suspensions. Higher K-values (K60, K90, K120) have higher molecular weights and viscosities, providing stronger binding and more robust film-forming properties, often employed in hair sprays, adhesives, and sustained-release drug formulations.

In the pharmaceutical industry, PVP is recognized as an important excipient globally. It serves multiple critical functions, including:Tablet Binder: Enhancing the cohesion of powder particles in tablet formulations, ensuring mechanical strength.
Film-Coating Agent: Providing protective, aesthetic, or functional coatings for tablets.
Solubilizer: Improving the solubility of poorly soluble active pharmaceutical ingredients through complexation.
Dispersing Agent: Ensuring uniform distribution of active ingredients in solid and liquid formulations.
Stabilizer: Preventing aggregation or sedimentation in suspensions and emulsions.

Beyond pharmaceuticals, PVP's unique properties make it indispensable in the cosmetic industry. It is a primary ingredient in hair styling products like hair sprays, gels, and mousses, where its film-forming ability provides hold. It also functions as a dispersant for pigments in makeup, a thickener in creams and lotions, and a binder in toothpaste and masks. Its safety profile makes it suitable for direct application to skin and hair.

Industrial applications are equally diverse, utilizing PVP's binding, dispersing, and complexing capabilities. It is used in adhesives, textiles (as a dye dispersant or sizing agent), paper manufacturing, printing inks, and as a component in filtration membranes and water treatment processes. The stability of PVP to heat, acids, and salts under typical processing conditions contributes to its reliability in these varied environments.
