HydroxyPropyyl methylcellose (qib HPMC) yog hypromellose tshuaj thiab ntxiv, dispersifement, emulsifier thiab zaj duab xis tus neeg sawv cev.
Cov khoom lag luam me me no ether muaj ntawm lub cev me me hauv kev sib txawv ntawm cov kab mob met hauv paus me me (CP, CP) thiab peb cov qib CP) Paj rwb linter thiab ntoo pulp, ntsib txhua qhov yuav tsum tau ntawm USP, EP, BP, nrog rau kosher thiab halal ntawv pov thawj.
Hauv cov txheej txheem tsim khoom, huv huv lub paj rwb yog etherified rau methyl chloride thiab propylene oxide los tsim dej-solub-soluble, tsis yog-ionic cellulose ether. Tsis muaj cov tsiaj muaj kev siv nyob rau hauv kev tsim HPMC.hpmc tuaj yeem siv los ua phau ntawv rau cov ntsiav tshuaj ntau yam xws li cov ntsiav tshuaj thiab cov granules. Nws kuj tseem ua cov piv txwv, rau cov piv txwv, hauv kev txhim kho dej khaws cia, ua yeeb yam ua kev tiv thaiv kev tiv thaiv vim nws cov kev ua si ntawm cov chaw, thiab kev tsim zaj duab xis, thiab zaj duab xis.
Qhov tsim nyog HPMC muab ntau lub luag haujlwm xws li kev txuag dej, kev tiv thaiv kev tiv thaiv kev tiv thaiv kab ntsig, kev tso tawm saum npoo av. Nws yog ib qho tsis-ionic compound tiv taus salting tawm thiab ruaj khov tshaj li ntau tshaj qhov dav. Cov kev siv uas raug ntawm HPMC yog binder rau cov ntaub ntawv dosage
Mharma HPMC los nyob rau hauv muaj kev viscosity viscosity nyob rau 3 txog 200,000 CPS, thiab nws tuaj yeem sau tau dav rau cov ntsiav tshuaj, bickenter, thickener, xaim thiab ua zaub hpmc tshuaj ntsiav.
