General description

Sodium carboxymethyl cellulose (CMC) is a class of linear structured cellulose which consists of polysaccharide composing the fibrous tissue 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
