Usage of Polyvinylpyrrolidone
1.Pharmaceutical Industry (Core Application)
Polyvinylpyrrolidone is used as the most widely used water-soluble binder for tablets, granules and capsules. Also used as solubilizer,suspending agent and film-forming agent in oral liquids, injections and ophthalmic preparations. It is also thekey raw material for povidone-iodine (PVP-I) disinfectants.
2.Cosmetic & Personal Care Industry
Polyvinylpyrrolidone is used as film former, thickener, dispersant and hair fixative in hair sprays, mousses, skincare creams, lotionsand color cosmetics. Improves product texture and provides long-lasting performance.
3.Food & Beverage Industry
Polyvinylpyrrolidoneis used asdlarifying agent and stabilizer for beer, wine, fruit juice and vinegar. Adsorbs polyphenols and proteinsto improve product clarity and extend shelf life.
4.Industrial Coatings & Inks Industry
Polyvinylpyrrolidone is used as dispersant, leveling agent and adhesion promoter in water-based coatings, inks and pigments.Improves pigment dispersion and coating adhesion.
5.Textile Industry
Polyvinylpyrrolidone is used as sizing agent, dye dispersant and color fastness improver in textile printing and dyeing processes.
6.Biotechnology & Other Fields
Polyvinylpyrrolidone is used as protein purification, cell culture media and detergent formulations. Also applied in batterymanufacturing and water treatment.
