It has good solubility, biocompatibility, and physiologically inert, film-forming character, colloid protect ability and compound ability to many organic or inorganic compounds. It is also steady to acid, salt and heat, so it is widely used.Technical grade quality standard Product nameK15K17K25K30K90K value13-1815-1922-2826-3381-97Efficient content(%)>95>95>95>95>95Vinylpyrrolidone(%)<0.2<0.2<0.2<0.2<0.2Ash %(sulphate)<0.1<0.1<0.1<0.1<0.1Moisture(%)<5.0<5.0<5.0<5.0<5.0PH value(5% aqueous solution)3-73-73-73-73-7Technical grade PVP applicationPVP application in daily used chemical productIn daily used beauties PVP has best dispersivity and film forming characters, it can be used as case-hardened liquid, hair spray, case-hardened agent of mousse, opacifying agent of Hair conditioner, foam stabilizer and wave case-hardened agent of shampoo, dispersant and affinity agent of tint. Adding PVP in vanishing cream, sunproof cream and depilation agent can increase the wettish and lubricative effect. In addition, adding PVP in detergent can prevent annesl and increase the wash capability. PVP application in industry and high-tech domain PVP in dyestuff, paint ink, fiber dye and color kinescope can use as surface cladding agent, dispersant, thickening agent and bond. PVP can improve on the bond ability to metal, glass, plastic and so on. Otherwise, PVP are widely used in separation film, lightcured composit...pPVP k30 (povidone k-30 polyvinylpyrrolidone)1MF C6H9NO)n 2CAS9003-39-8 3StandardCP2005/USP274.PVP K30,K15,K25  PVP k30 (povidone k-30 polyvinylpyrrolidone)PVP k30 (povidone k-30 polyvinylpyrrolidone)PVP K30PVP-K series can be used as film-forming agent, viscosity-enhancing agent, lubricator and adhesive in hair sprays, mousse, hair-fixing gels and solution.
