In the realm of specialty chemicals, Polyvinylpyrrolidone K90 (PVP K90) stands out as a remarkably versatile polymer, finding extensive use across pharmaceutical, cosmetic, and industrial sectors. Its unique combination of physical and chemical properties makes it an indispensable component in numerous formulations. This guide explores the essential aspects of PVP K90, its diverse applications, and the advantages of sourcing it from reliable manufacturers and suppliers in China.

PVP K90, characterized by its high molecular weight (ranging from 1,000,000 to 1,500,000 Daltons), is a water-soluble, non-ionic polymer derived from N-vinylpyrrolidone. Its K-value system, with K90 representing the highest end of the scale, directly correlates with its viscosity and binding strength. This high viscosity translates into superior performance in applications requiring robust adhesion and film formation.

The core properties that make PVP K90 so valuable include:

  • Excellent Film-Forming: It creates hard, glossy, and transparent films, ideal for coatings and styling products.
  • Strong Adhesion: Its adhesive properties are crucial for tablet binding and other bonding applications.
  • Good Solubility: PVP K90 dissolves readily in water and a variety of organic solvents, offering formulation flexibility.
  • Stabilization: It effectively stabilizes emulsions, dispersions, and suspensions.
  • Biocompatibility and Low Toxicity: Making it a preferred choice for pharmaceutical and cosmetic uses.

The applications of PVP K90 are exceptionally broad:

  • Pharmaceuticals: It serves as a critical excipient, acting as a binder in tablets, a solubilizer for poorly soluble drugs, a disintegrant, and a stabilizer for suspensions and heat-sensitive active substances. Its role in improving drug delivery and stability is paramount.
  • Cosmetics: In personal care products, PVP K90 is a key ingredient in hair styling products (gels, mousses, sprays) for its strong hold and film-forming capabilities. It also functions as an emulsion stabilizer and thickener in skin and oral care products.
  • Industrial Uses: PVP K90 finds applications in membranes for water purification, as an adhesive in inks and coatings, and as a dispersant in textile dyeing. Its versatility extends to electronics, metallurgy, and paper manufacturing.
