Carboxymethyl ethoxy ethyl cellulose

Carboxymethyl ethoxy ethyl cellulose (CMEC) yog ib qho kev hloov kho cellulose derivative uas tau siv dav hauv cov khoom noj, tshuaj, thiab tshuaj pleev ib ce. Nws yog tsim los ntawm reacting ethyl cellulose nrog sodium chloroacetate thiab ces ntxiv reacting nrog sodium hydroxide los tsim carboxymethyl pawg. Tom qab ntawd cov khoom tsim tau raug kho nrog ethylene oxide los qhia ethoxy thiab ethyl pawg.

CMEC yog siv los ua cov thickener, stabilizer, thiab emulsifier hauv ntau yam khoom noj xws li kua ntses, hnav khaub ncaws, thiab dej haus. Nws kuj yog siv nyob rau hauv pharmaceuticals raws li ib tug binder thiab disintegrant nyob rau hauv cov ntsiav tshuaj thiab tsiav tshuaj. Hauv cov tshuaj pleev ib ce, CMEC yog siv los ua cov thickener thiab emulsifier hauv cov tshuaj pleev ib ce thiab cream.

CMEC yog cov hmoov dawb dawb uas yog soluble hauv dej thiab cov kuab tshuaj organic. Nws muaj qhov zoo thermal stability thiab tuaj yeem tiv taus qhov kub thiab txias thiab acidic. CMEC feem ntau suav hais tias muaj kev nyab xeeb rau kev siv cov khoom noj thiab tshuaj, thiab nws tau pom zoo los ntawm cov koom haum tswj hwm xws li FDA thiab European Food Safety Authority.
