Povidone, commonly known as Polyvinylpyrrolidone (PVP), is a highly versatile polymer that has found extensive application across numerous industries, with a particular emphasis on pharmaceuticals and cosmetics. Among its various grades, Povidone K25 (PVP K25) is a medium molecular weight variant that offers a balanced set of properties making it an indispensable ingredient for manufacturers and formulators. As a premier supplier of high-quality chemical materials, we aim to provide a comprehensive understanding of PVP K25's utility.

Understanding Povidone K25: Properties and Characteristics

PVP K25, with CAS number 9003-39-8, presents as a white to slightly yellowish powder. Its key characteristics include:

  • Excellent Solubility: It dissolves readily in water, ethanol, and many organic solvents, facilitating easy incorporation into diverse formulations.
  • Film-Forming Capability: PVP K25 forms clear, stable films, which is advantageous in tablet coatings, hair styling products, and protective layers.
  • Binding Properties: It acts as an effective binder in tablet manufacturing, contributing to tablet hardness and integrity.
  • Dispersing and Stabilizing Actions: PVP K25 can stabilize suspensions and emulsions, and disperse solid particles, making it useful in liquid preparations and industrial applications.
  • Biocompatibility and Low Toxicity: Its inert nature and safety profile are critical for pharmaceutical and cosmetic applications.

These properties collectively make PVP K25 a reliable and efficient choice for a wide range of applications.

Key Application Areas for PVP K25

The versatility of PVP K25 allows it to serve critical functions in several key industries:

  • Pharmaceuticals: Widely used as a binder, solubilizer, stabilizer, and suspending agent in tablets, capsules, injections, and ophthalmic solutions. Its ability to improve drug bioavailability by forming amorphous solid dispersions is particularly notable. We supply pharmaceutical-grade PVP K25 that meets USP/BP/EP standards, ensuring the highest quality for your drug products.
