Carboxymethyl cellulose sodium salt

Carboxymethyl Cellulose Sodium Salt is a high viscosity carboxymethylcellulose (CMC); the viscosity of a 1% solution in water at 25 °C is 1300-2200 centipoise (cps). The viscosity is both concentration and temperature dependent. As the temperaure increases, the viscosity decreases. As the concentration increases, the viscosity increases.


  • High Viscosity Grade
  • pKa: 4.30(Lit.)


CMC is used in drilling muds, in detergents as a soil-suspending agent, in resin emulsion paints, adhesives, printing inks, textile sizes, as protective colloid in general. As stabilizer in foods. Used in pharmaceuticals as a suspending agent, tablet excipient, viscosity-increasing agent and in the development of biostructures such as biofilms, emulsions and nanoparticles for drug delivery. It is used as a suspending agent, viscosity modifiers (thickeners) to stabilize emulsions and as a chemical dispersants of oils and other carbon structures such as nanotubes. High viscosity is used to make a mixture which resembles a cream or lotion.
Degree of polymerization: approximately 3200; Degree of substitution: approximately 6.5-8.5 carboxymethyl groups per 10 anhydroglucose units; Sodium content: approximately 8% by weight; Derivation: Cellulose fiber with sodium hydroxide and chloroacetic acid.


Soluble in aqueous solution. High viscosity CMC is soluble at up to 50 mg/ml concentration but heat may be required.
