Carboxymethyl cellulose - Wikipedia

Carboxymethyl cellulose (CMC) or cellulose gum or tylose powder is a cellulose derivative with carboxymethyl groups (-CH2-COOH) bound to some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone. It is often used as its sodium salt, sodium carboxymethyl cellulose.
