It is a carboxymethyl derivative of cellulose and the most important ionic cellulose gum. Sodium carboxymethyl cellulose is usually an anionic polymer compound obtained by reacting natural cellulose with caustic soda and monochloroacetic acid, with a molecular weight ranging from several thousand to one million. CMC-Na is a white fibrous or granular powder, odorless, tasteless, hygroscopic, and easy to disperse in water to form a transparent colloidal solution.
