General description

Sodium carboxymethyl cellulose (CMC) belongs to the class of anionic linear structured cellulose. Its components consist of polysaccharide composed of fibrous tissues of plants. It is a water soluble polymer which can be used as a polyelectrolyte cellulose derivative.

Application

CMC can be used for a wide range of application such as:
  • food processing, textiles, detergents, and drugs
  • a stabilizer in the preparation of nanoparticles
  • a binder for the formation of electrodes
