Carboxymethylcellulose Natriumsalz, 200 - 800 cps, Pulver, mittlere Viskosität
Lieferant: ICN Biomedicals
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.
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 at 25 °C. High viscosity CMC is soluble at up to 50 mg/ml concentration but heat may be required.
The solid should be added to the water. Stir gently or shake intermittently; do not stir constantly with a magnetic stirring bar.
