Stir gently or shake intermittently do not stir constantly with a magnetic stirring bar. High viscosity CMC is soluble at up to 50 mg/ml concentration but heat may be required. High viscosity is used to make a mixture which resembles a cream or lotion.ĭegree 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. 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. 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. As the concentration increases, the viscosity increases.ĬMC 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 the temperaure increases, the viscosity decreases. The viscosity is both concentration and temperature dependent. Carboxymethyl Cellulose Sodium Salt is a high viscosity carboxymethylcellulose (CMC) the viscosity of a 1% solution in water at 25 ☌ is 1300-2200 centipoise (cps).
