PVP

Polyvinyl Pyrrolidone PVP

PVP (polyvinylpyrrolidone) yog dej-soluble hluavtaws polymer renowned rau nws tshwj xeeb khi, film-forming, thiab stabilizing zog. Nrog rau biocompatibility zoo heev thiab tsis muaj toxicity, nws ua hauj lwm raws li ib tug tshuaj pleev ib ce (hairsprays, tshuaj zawv plaub hau), ib tug tseem ceeb excipient nyob rau hauv kws tshuaj (cov ntsiav tshuaj binders, capsule coatings, lub qhov txhab ntawm lub qhov txhab), thiab muaj daim ntaub ntawv (inks, ceramics, detergents). Nws muaj peev xwm ua kom muaj peev xwm ua kom zoo dua solubility thiab bioavailability ntawm APIs. PVP's tunable molecular weights (K-values) muab kev hloov pauv ntawm cov qauv tsim, kom ntseeg tau tias qhov zoo tshaj plaws viscosity, adhesion, thiab dispersion tswj.
