Description
Polyvinylpyrrolidone (CAS 9003-39-8), commonly known as PVP or Povidone, is a highly versatile, water-soluble polymer derived from N-vinylpyrrolidone monomer. Renowned for its excellent solubility in water and many organic solvents, low toxicity, and superb film-forming capabilities, PVP is a staple excipient in the pharmaceutical industry. It serves multiple functions, including acting as a binder, disintegrant, solubilizing agent, suspending agent, and coating polymer in various dosage forms. PVP is available in different molecular weight grades (designated by K-values, e.g., K-15, K-30, K-90) allowing for tailored performance. As a premier supplier, we offer high-quality PVP grades suitable for pharmaceutical, cosmetic, food, and industrial applications.

PVP’s versatility leads to its use across numerous industries:
- Pharmaceutical Excipient:
- Tablet Binder: Helps bind active ingredients and other excipients together in tablets.
- Solubility Enhancer: Improves the dissolution rate and bioavailability of poorly soluble drugs.
- Film Former: Used in tablet coatings to protect the drug, mask taste, or control release.
- Suspending Agent: Keeps insoluble particles dispersed in liquid formulations.
- Disintegrant: Helps tablets break apart after administration.
- Viscosity Modifier: Used in eye drops and other liquid preparations.
- Cosmetics & Personal Care: Film-former in hair styling products (sprays, gels), thickener in lotions and shampoos, dispersant for pigments.
- Food Industry (E1201): Clarifying agent for beverages (beer, wine), stabilizer, thickener, tablet binder for supplements.
- Industrial Applications: Adhesives (glue sticks), inks, coatings, textile manufacturing, membrane production.
- Medical Devices: Contact lens wetting solutions, coatings.

Packaging and Transportation
Our Polyvinylpyrrolidone is packaged in tightly sealed containers, typically fiber drums with internal polyethylene liners or multi-layer bags, to protect it from moisture due to its hygroscopic nature. Standard transportation procedures for non-hazardous chemical powders are followed, ensuring product integrity upon delivery.
Storage
Store Polyvinylpyrrolidone in a cool, dry place in tightly sealed containers to prevent moisture absorption. Keep away from excessive heat.
