Carboxymethyl Cellulose (CMC) is a water-soluble, anionic cellulose ether derived from natural cellulose through chemical modification. It is widely used as a thickener, stabilizer, binder, rheology modifier, and water-retention agent in various industries.
CMC offers excellent viscosity control, high purity, good salt tolerance, and stable performance under different processing conditions. Due to its reliable quality and versatile functionality, CMC is extensively applied in detergents, food, construction materials, ceramics, oil drilling fluids, pharmaceuticals, paper, and textile industries.
