microcrystalline cellulose yog dab tsi

Microcrystalline cellulose (MCC) yog cov khoom siv ntau yam thiab siv dav hauv kev lag luam tshuaj, zaub mov, tshuaj pleev ib ce, thiab lwm yam lag luam. Nws yog muab los ntawm cellulose, uas yog ib tug natural polymer nyob rau hauv lub cell phab ntsa ntawm cov nroj tsuag, tshwj xeeb tshaj yog nyob rau hauv ntoo pulp thiab paj rwb.

Nov yog qee cov yam ntxwv tseem ceeb thiab cov khoom ntawm microcrystalline cellulose:

1. Particle Loj: MCC muaj cov me me, cov khoom sib xws nrog ib txoj kab uas hla feem ntau ntawm 5 txog 50 micrometers. Qhov me me me me pab txhawb rau nws cov flowability, compressibility, thiab blending zog.
2. Crystalline Structure: MCC yog tus yam ntxwv los ntawm nws cov qauv microcrystalline, uas yog hais txog kev npaj ntawm cellulose molecules nyob rau hauv daim ntawv ntawm me me crystalline cheeb tsam. Cov qauv no muab MCC nrog rau txhua yam muaj zog, ruaj khov, thiab tsis kam mus rau degradation.
3. Dawb los yog Off-White Powder: MCC feem ntau muaj raws li cov hmoov zoo, dawb los yog tawm-dawb nrog cov ntxhiab tsw nruab nrab thiab saj. Nws cov xim thiab tsos ua rau nws haum rau siv nyob rau hauv ntau yam formulations yam tsis muaj kev cuam tshuam rau qhov pom los yog sensory yam ntxwv ntawm cov khoom kawg.
4. High Purity: MCC feem ntau yog ua kom huv heev kom tshem tawm cov impurities thiab cov kab mob, kom nws muaj kev nyab xeeb thiab sib haum nrog kev siv tshuaj thiab zaub mov. Nws yog feem ntau tsim los ntawm kev tswj cov txheej txheem tshuaj ua raws li kev ntxuav thiab ziab cov kauj ruam kom ua tiav qib siab purity.
5. Dej Insoluble: MCC yog insoluble hauv dej thiab feem ntau cov kuab tshuaj organic vim nws cov qauv crystalline. Qhov no insolubility ua rau nws haum rau siv raws li ib tug bulking agent, binder, thiab disintegrant nyob rau hauv cov ntsiav tshuaj formulations, raws li zoo raws li ib tug anti-caking agent thiab stabilizer nyob rau hauv cov khoom noj.
6. Kev Sib Txuas Zoo Tshaj thiab Compressibility: MCC nthuav tawm cov khoom zoo sib xws thiab kev sib xyaw ua ke, ua rau nws yog qhov zoo tshaj plaws rau kev tsim cov ntsiav tshuaj thiab tshuaj ntsiav hauv kev lag luam kws tshuaj. Nws pab tswj kev ncaj ncees thiab txhua yam lub zog ntawm cov ntaub ntawv compressed ntau npaum li cas thaum tsim khoom thiab khaws cia.
7. Tsis yog-Toxic thiab Biocompatible: MCC feem ntau lees paub tias muaj kev nyab xeeb (GRAS) los ntawm cov cai tswj hwm rau kev siv khoom noj thiab tshuaj. Nws yog non-toxic, biocompatible, thiab biodegradable, ua rau nws haum rau ntau yam kev siv.
8. Cov Khoom Siv Ua Haujlwm: MCC muaj ntau yam kev ua haujlwm, suav nrog kev txhim kho ntws, lubrication, nqus dej, thiab tswj kev tso tawm. Cov khoom no ua rau nws muaj ntau yam excipient rau kev txhim kho kev ua, kev ruaj ntseg, thiab kev ua tau zoo ntawm formulations nyob rau hauv txawv industries.

microcrystalline cellulose (MCC) yog ib qho khoom muaj txiaj ntsig nrog ntau hom kev siv tshuaj, khoom noj, tshuaj pleev ib ce, thiab lwm yam lag luam. Nws qhov tshwj xeeb ua ke ntawm cov khoom ua rau nws yog ib qho tseem ceeb ntawm cov khoom siv hauv ntau cov qauv, ua rau muaj txiaj ntsig zoo, kev ua tau zoo, thiab kev nyab xeeb ntawm cov khoom kawg.
