Carboxyl methyl cellulose
Carboxy methyl cellulose (cmc) kapena cmc tricker ndi celloucar ndi ma cellour omwe ali ndi magulu a carboxymethyl (-ch2-cooh) omangidwa kwa morcomyrase. Nthawi zambiri imagwiritsidwa ntchito ngati mchere wake wa sodium, sodium carboxymethyl cellulose.
Amapangidwa ndi alkali - othandizira a cellulose okhala ndi chlorooceic asidi. Polar (worganic acid) Magulu a Carboxyl amapereka ma cellulose soleble ndikugwiritsa ntchito mwachilengedwe. Katundu wa CMC amadalira kuchuluka kwa malo ogwiritsira ntchito cellulose (mwachitsanzo, kuchuluka kwa magulu a hydroxyl omwe atenga nawo mbali m'malo mwake), komanso kutalika kwa malire a Carboxymethyl.
