What is Polyvinylpyrrolidone PVP ?
Polyvinyl pyrrolidone (PVP), a non-ionic polymer, is one of the most distinctive, well-studied and widely studied fine chemicals in N-vinylamide polymers. Has developed into non-ionic, cationic, anionic 3 categories, industrial grade, medical grade, food grade 3 specifications, relative molecular weight from thousands to more than one million homopolymer, copolymer and crosslinked polymer series products, and with its excellent unique properties have been widely used.

Polyvinylpyrrolidone is written"pvp"for short, it can be dissolved in water and varieties of organic solvent and is hygrosopic ability, film-forming capability, complexing ability and physiology compatibility are good. Hygroscopic ability, film-forming capability, complexing ability and physiology compatibility are good.
In field of cosmetic:pvp series can be used as filming-agent, viscosity-enhancement agent, lubricator and adhesive. They are the key component of hair sprays , mousse, gels and lotions, hair-dring reagent and shampoo in hair-care products and the key component of lip-stick, sunscreem and lotions in skin-care products and also that of eye makeup, deodorant and dentifrice, etc. In field of pharmaceutical:pvp-k30 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 antitoxical assistant for eye drug. In field of other vtilities:paint and coating, plastics and resin adhesive, glass fiber, film, ink, tv tube, detergent, biocide, tabulating assistant, textile dyeing and printing, etc.
Cosmetic: PVP-K series can be used as film-forming agent, viscosity-enhancing agent, lubricator and adhesive in hair sprays, mouses, hair-fixing gels and colution. They are also useful auxiliary materials in skin-care product, hair-dying reagent, shapoo, lipstick, deodorant, sunscreen and dentifrice.
Pharmaceutical: PVP-K30 (pharmaceutical grade) is a kind of new excellent pharmaceutical excipient. It is mainly used as binder for tablet and granule, dissovlving assistant for injection, flow assistant for capsule, dispersant for liquid medicine and pigment, stabilizer for enzyme and heat-sensitive drug, co-precipitant for poorly soluble drugs, lubricator and antitoxic assistant for eye drug. PVP has been used as excipient in more than one hundred drugs.
Other Utility: Suspensant, dispersant and emulsifier disinfector
Paint and coating Printing ink
Textile and dyestuff Building material
Paper making TV kinescope
Polymer ultra-filtration membrance, micro-filtration membrance
