For procurement managers and formulation scientists in the pharmaceutical industry, identifying and sourcing high-quality excipients is a constant pursuit. Polyvinylpyrrolidone (PVP) K15 is one such excipient that offers a remarkable combination of properties, making it indispensable in various drug delivery systems. This article serves as a comprehensive overview for pharmaceutical buyers, highlighting the advantages of PVP K15 and the importance of partnering with a dependable manufacturer in China.

What is Polyvinylpyrrolidone (PVP) K15?

PVP K15, identified by CAS number 9003-39-8, is a synthetic, water-soluble polymer derived from N-vinylpyrrolidone. It is characterized by its low molecular weight and viscosity, offering excellent solubility in water and many organic solvents. Its chemical structure provides it with a range of beneficial properties, including binding, film-forming, dispersing, stabilizing, and complexing capabilities. It is widely recognized for being non-toxic, non-irritating, and physiologically inert, making it exceptionally safe for pharmaceutical use.

Key Applications in Pharmaceutical Formulations

The versatility of PVP K15 allows it to be utilized in numerous pharmaceutical applications:

  • Tablet Binder: PVP K15 is an excellent binder for both wet and dry granulation, as well as for direct compression. It imparts sufficient hardness to tablets and aids in achieving uniform particle size and flow.
  • Solubilizer: It effectively enhances the solubility and dissolution rate of poorly water-soluble drugs through solid dispersion techniques, thereby improving bioavailability.
  • Coating Agent: Forms smooth, adherent films on APIs and dosage forms, useful for taste masking, protection, and controlled release.
  • Stabilizer and Dispersant: Prevents aggregation and sedimentation in liquid and semi-solid formulations, ensuring product homogeneity.

Why Source PVP K15 from a Reputable China Manufacturer?

When you are looking to buy PVP K15, choosing the right supplier is critical. Partnering with a reputable manufacturer in China offers several advantages:

  • Cost-Effectiveness: China is a global hub for chemical manufacturing, offering competitive pricing for high-quality materials.
  • Quality Assurance: Leading manufacturers adhere to international quality standards (e.g., GMP, ISO) and implement stringent quality control measures.
  • Reliable Supply: Established manufacturers have robust production capacities and supply chains to ensure consistent availability.
  • Technical Support: Many suppliers provide excellent technical data, formulation support, and regulatory assistance.
