Sodium CMC

Sodium carboxymethyl cellulose (CMC-Na) is an organic compound with the chemical formula [C6H7O2(OH)2OCH2COONa]n. It is a carboxymethylated derivative of cellulose and the most important ionic cellulose gum. Sodium carboxymethyl cellulose is usually an anionic high-molecular compound produced by the reaction of natural cellulose with caustic alkali and monochloroacetic acid, with a molecular weight ranging from several thousand to millions. CMC-Na is a white fibrous or granular powder, odorless, tasteless, hygroscopic, and easily dispersed in water to form a transparent colloidal solution.
