Microcrystalline Cellulose (MCC) | 9004-34-6
Khoom Description
Microcrystalline cellulose yog ib lub sij hawm rau refined ntoo pulp thiab siv raws li ib tug texturizer, ib tug anti-caking tus neeg saib xyuas, ib tug rog hloov, ib tug emulsifier, ib tug extender, thiab ib tug bulking tus neeg sawv cev nyob rau hauv cov khoom noj khoom haus ntau lawm daim ntawv yog siv nyob rau hauv vitamin tshuaj los yog ntsiav tshuaj. Nws kuj tseem siv rau hauv cov tshuaj plaque rau suav cov kab mob, ua lwm txoj hauv kev carboxymethylcellulose.Ntau txoj hauv kev, cellulose ua rau qhov zoo tshaj plaws excipient. Ib qho polymer tshwm sim, nws yog tsim los ntawm cov piam thaj txuas nrog 1-4 beta glycosidic daim ntawv cog lus. Cov kab hluav taws xob cellulose no tau ntim ua ke raws li microfibril spiraled ua ke hauv cov phab ntsa ntawm cov nroj tsuag. Txhua microfibril nthuav tawm cov qib siab ntawm peb sab hauv kev sib txuas ua ke uas ua rau muaj cov qauv crystalline uas tsis muaj dej nyob hauv dej thiab tiv taus cov tshuaj reagents. Txawm li cas los xij, muaj qee qhov tsis muaj zog ntawm microfibril nrog kev sib raug zoo hauv lub cev. Cov no yog hu ua amorphous regions tab sis raug hu ua dislocations vim microfibril muaj ib-theem qauv. Lub cheeb tsam crystalline yog cais los tsim microcrystalline cellulose.
