Dab tsi yog cov txiaj ntsig ntawm kev siv hydroxypropyl methylcellulose ua cov tshuaj ntsiav hollow?

Cov khoom no yog 2-hydroxypropyl ether methyl cellulose, uas yog ib tug semi-synthetic khoom. Nws tuaj yeem tsim los ntawm ob txoj hauv kev: (1) Tom qab kho cov paj rwb lossis cov ntaub ntoo ntoo nrog cov dej qab zib caustic, lawv tau tov nrog chloromethane thiab epoxy Propane reacts, refined thiab pulverized kom tau nws; (2) Siv cov qib tsim nyog ntawm methyl cellulose los kho nrog sodium hydroxide, hnov ​​​​mob nrog propylene oxide nyob rau hauv qhov kub thiab txias siab mus rau qhov zoo tagnrho, thiab ua kom zoo dua. Qhov hnyav molecular li ntawm 10,000 txog 1,500,000.

★ Lub tswv yim ntshiab ntuj, txhim khu kev zom thiab nqus.

★ Cov ntsiab lus dej tsawg, 5% -8%. Muaj zog noo noo nqus tsis kam, cov ntsiab lus tsis yooj yim rau agglomerate, thiab lub plhaub capsule tsis yooj yim rau deform, ua nkig, thiab tawv.

★ Tsis muaj kev pheej hmoo ntawm kev sib txuas cov tshuaj tiv thaiv, tsis muaj kev cuam tshuam, kev ruaj ntseg siab, txij li hydroxypropyl methylcellulose yog cellulose derivative, tsis muaj kev pheej hmoo ntawm kev sib txuas cov tshuaj tiv thaiv ntawm cov tshuaj protein hauv gelatin.

★ Cov kev cai qis rau kev cia khoom:

Nws yuav luag tsis nkig nyob rau hauv ib puag ncig uas tsis muaj av noo, muaj kev ruaj ntseg zoo ntawm qhov kub thiab txias, thiab cov tshuaj ntsiav tsis deform.

★ Uniform qauv thiab zoo sib xws:

Muaj feem xyuam rau lub teb chaws cov qauv tshuaj pharmacopoeia, cov duab, qhov loj me, qhov tsos thiab cov qauv filling yog sib npaug rau gelatin hollow capsules, thiab tsis tas yuav hloov cov khoom siv thiab qhov chaw.

★ Cov khoom tsis yog tsiaj txhu, tsis muaj kev pheej hmoo ntawm kev loj hlob hormone lossis tshuaj nyob hauv lub cev tsiaj.

Hydroxypropyl methylcellulose yog sivnpliag capsules yog txawv los ntawm cov tshuaj gelatin npliag capsules. Lawv yog hydroxypropyl methylcellulose (HPMC) ua los ntawm ntoo pulp. Ntxiv rau qhov zoo ntawm lub tswv yim ntuj ntshiab, hydroxypropyl methylcellulose khoob capsules kuj tuaj yeem txhim kho kev nqus thiab zom cov protein, rog thiab carbohydrates, thiab muaj cov txiaj ntsig zoo thiab cov yam ntxwv uas cov tshuaj gelatin hollow capsules tsis muaj. Nrog rau kev txhim kho txuas ntxiv ntawm tib neeg txoj kev paub txog kev saib xyuas tus kheej, kev loj hlob ntawm cov neeg tsis noj nqaij, tshem tawm cov kab mob dev vwm, kab mob ko taw thiab qhov ncauj ntawm tib neeg kev noj qab haus huv, thiab kev cuam tshuam ntawm kev ntseeg thiab lwm yam, cov khoom lag luam ntshiab ntuj thiab cov tshuaj ntsiav tshuaj. yuav dhau los ua tus thawj coj rau kev txhim kho kev lag luam capsule. .
