Povidone K-90 (PVP K-90)

Povidone K-90, also known as polyvinylpyrrolidone (PVP) K-90, is a polymer with various applications in pharmaceuticals, cosmetics, and other industries

Uses:

1. Pharmaceuticals: Povidone K-90 is widely used in the pharmaceutical industry for its various properties, including:
   • Binder: It is used as a binder in the formulation of tablets and granules. As a binder, it helps to hold the active pharmaceutical ingredients together, ensuring the uniformity and integrity of the dosage form.
   • Disintegrant: Povidone K-90 can also act as a disintegrant in tablets, facilitating the rapid breakup of the tablet into smaller particles when in contact with fluids, thereby aiding in drug release.
   • Solubilizer: It is used as a solubilizing agent to enhance the solubility of poorly water-soluble drugs in aqueous solutions, improving their bioavailability.
   • Stabilizer: Povidone K-90 is used as a stabilizer in oral and topical formulations to prevent the degradation of active ingredients caused by oxidation or light exposure.
   • Vehicle for Drug Delivery: It can serve as a carrier or vehicle for drug delivery systems, such as oral suspensions and topical gels.
2. Cosmetics: Povidone K-90 is used in cosmetic formulations for its film-forming and stabilizing properties. It can be found in products such as hair sprays, mousses, and gels, where it helps to provide hold and durability to styling products.
3. Industrial Applications: Povidone K-90 is also used in various industrial applications, including adhesives, coatings, and inks, where its adhesive and film-forming properties are beneficial.
