Application:
Technical grade Polyvinylpyrrolidone are being used in Textiles/Fibers,Adhesives,Coatings/paintings,Laundry/Household detergent,Inks,Ceramics and other hi-tech industries.
Povidone is one of the most important excipient in the worldwide for pharmaceutical industry,whatever for human health care products and animal health care products.It’s more and more used as:1)Binder for tables,capsule, 2)Sugar coatings and films, 3)Thickening agent, 4)Solubility Improver for poorly soluble drugs, 5)Bioavailability Enhancer for drug’s active ingredients, 6)Pore-forming for membrane products.
Cosmetic Grade Polyvinylpyrrolidone products are suitable for fourmulations which used as film forming and viscosity modification,especially in hair styling products, mousse gels and lotions & solution, PVPs also used as dispersion agent in Hair-dying, pigment products’ formulations.
