“…3 Therefore, based on this structure, further modication and chemical functionalisation of cellulose have been successfully achieved to generate materials with desired properties, such as cellulose acetate, cellulose nitrate, methylcellulose, and carboxymethyl cellulose. 4 Carboxymethyl cellulose (CMC) is a well-known anionic derivative of the cellulose family that exhibits high solubility in water and a higher molecular weight than cellulose. 5 It can be produced by replacing one of the hydroxyl groups in the AGU with a sodium carboxymethyl group.…”
