Cosmetics: PVP-K series can be used as film-forming agent, viscosity-enhancement agent, lubricator and adhesive. They are the key component of hair sprays, mousse, gels and lotions & solution, hair-dying reagent and shampoo in hair-care products. They can be used as assistant in skin-care products, eye makeup, lipstick, deodorant, sunscreen and dentifrice.

Pharmaceutical: Povidone K30 and K90 is a new and excellent pharmaceutical excipient. It is mainly used as binder for tablet, dissolving assistant for injection, flow assistant for capsule, dispersant for liquid medicine and stain, stabilizer for enzyme and heat sensitive drug, coprecipitant for poorly soluble drugs, lubricator and antitoxic assistant for eye drug. PVP works as excipients in more than one hundreds drugs.

Other Utilities: Also used as assistant in the realm of Paint and Coating, Plastics and Resin, Adhesives, Glass Fiber, Film, Ink, TV tube, Detergent, Biocide, Tabulating, Textile Dying and Printing, etc.
