Application:
Cosmetics:PVP-K series can be used as film-forming agents, viscosity-enhancement agents, lubricate and adhesive. They are the key component of hair sprays, monsse, gels and lotions and solution. They are also convenience assistant in skin-care product, hair-dying reagent shampoo, eye makeup, lipsticks, deodorants and dentifrices.Pharmaceutical:PVP K 30 is a new and excellent pharmaceutical recipe. It is mainly used as binder for tablet, dissolving assistant for injection, flow assistant for capsular, dispersant for liquid medicine and pigment, stabilizer for enzymes and heat sensitive drug, coprecipitant for poorly soluble drugs, lubricate and antitoxical assistant for eye drug. PVP has been used as excipients in more than hundred drugs.Others: 1.suspension, dispersant, emulsion 2.paint, coating 3.rubber, resin4.glass fiber5.ink6.binder7.purger 8.film9.drug auxiliary 10.picture tube11.medicinal tape 12.disinfectant13. paper auxiliaryPOLYVINYLPYRROLIDONE (PVP)
