Poly (n-vinylpyrrolidone)

N-vinylpyrrolidone monomer yog qhov pib ntawm cov khoom siv hluavtaws hu ua poly (N-vinylpyrrolidone) (PVP), qee zaum hu ua polyvidone lossis povidone. Cov dej-soluble polymer no muaj qhov sib txawv ntawm kev sib khi, kev ua yeeb yaj kiab, thiab cov yam ntxwv ruaj khov uas ua rau nws hloov tau mus rau ntau qhov kev siv hauv ntau qhov chaw.
PVP lub peev xwm los yaj hauv ntau cov kuab tshuaj organic thiab dej yog ib qho ntawm nws qhov tseem ceeb. Nws lub peev xwm ua haujlwm tau zoo hauv ntau qhov chaw ua rau nws muaj kev xaiv nrov hauv cov nplaum nplaum, tshuaj pleev ib ce, tshuaj, thiab lwm yam lag luam. PVP feem ntau ua hauj lwm raws li ib tug binder nyob rau hauv cov ntsiav tshuaj formulations nyob rau hauv kev lag luam tshuaj, qhov uas nws txhim kho lub cohesiveness ntawm lub active Cheebtsam. Nws yog tus nqa khoom zoo tshaj plaws rau kev xa tshuaj vim nws cov dej solubility thiab bioadhesive zoo, uas txhim kho cov solubility thiab bioavailability ntawm cov tshuaj.

Hauv cov tshuaj pleev ib ce thiab kev saib xyuas tus kheej, PVP yog cov khoom tseem ceeb hauv cov tshuaj pleev plaub hau, gels, thiab cov khoom tu tawv nqaij. Nws tsim ib zaj duab xis hloov tau yooj yim, pob tshab uas muab tuav thiab kev ntxhib los mos, thaum tseem ua tus stabilizer rau emulsions. Cov polymer no kuj tseem siv rau hauv kev daws teeb meem ntawm lub lens rau nws cov dej noo-retaining thiab lubricating zog, txhim kho cov neeg siv kev nplij siab.

Hauv kev lag luam kev lag luam, PVP yog siv rau hauv cov nplaum, txheej, thiab inks vim nws cov yeeb yaj kiab zoo heev thiab cov yam ntxwv nplaum. Tsis tas li ntawd, hauv kev lag luam zaub mov thiab dej haus, PVP yog siv rau hauv brewing raws li tus neeg saib xyuas kom tshem tawm cov polyphenols thiab cov proteins, ua kom pom tseeb dua thiab ruaj khov hauv dej haus.
