Puas yog hypromellose zoo ib yam li HPMC?

Yog lawm, hypromellose yog tib yam li HPMC (hydroxypropyl methylcellulose). Hypromellose yog lub npe thoob ntiaj teb uas tsis yog tswv cuab (INN) rau cov khoom siv no, thaum HPMC yog lub npe lag luam uas siv hauv kev lag luam.

HPMC yog hloov kho cellulose, qhov twg qee pawg hydroxyl ntawm cov cellulose molecule tau hloov nrog hydroxypropyl thiab methyl pawg. Nws yog cov hmoov dawb los yog dawb, tsis muaj ntxhiab, thiab tsis qab ntsev uas yog soluble hauv dej thiab cov kuab tshuaj organic.

HPMC feem ntau yog siv los ua cov thickener, binder, thiab emulsifier nyob rau hauv ntau yam kev siv, xws li tshuaj, khoom noj, tshuaj pleev ib ce, thiab cov khoom tu tus kheej. Nws cov khoom, xws li viscosity, solubility, thiab gelation, tuaj yeem hloov kho los ntawm qhov sib txawv ntawm kev hloov pauv (DS) thiab qhov hnyav molecular (MW) ntawm cov polymer.

Kev siv hypromellose hauv cov kws kho mob tshwj xeeb yog dav vim nws cov kev ua tau zoo thiab biocompatibility. Nws yog feem ntau siv los ua cov ntsiav tshuaj binder, disintegrant, thiab sustained-tso tus neeg saib xyuas, nrog rau cov thickener thiab suspending tus neeg sawv cev hauv cov kua formulations. Nws lub peev xwm los tsim ib lub gel ntawm cov concentration ntau dua kuj ua rau nws muaj txiaj ntsig zoo hauv kev tswj-tso daim ntawv thov.

Hypromellose kuj tseem siv rau hauv lwm cov lag luam. Piv txwv li, nws tuaj yeem siv los ua cov thickener, stabilizer, thiab emulsifier hauv cov khoom noj, xws li cov kua ntses, hnav khaub ncaws, thiab cov khoom siv mis nyuj. Hauv cov khoom tu tus kheej, hypromellose tuaj yeem siv los ua cov thickener thiab emulsifier hauv cov tshuaj pleev, tshuaj zawv plaub hau, thiab lwm yam tshuaj pleev ib ce.

hypromellose thiab HPMC xa mus rau tib yam khoom, uas yog ntau yam thiab dav siv polymer hauv ntau yam lag luam. Nws cov khoom thiab kev ua haujlwm tuaj yeem hloov kho raws li cov ntawv thov tshwj xeeb thiab cov khoom xav tau kawg.
