Carboxymethylcellulose sodium salt is used in drilling muds, in detergents as a soil-suspending agent, in resin emulsion paints, adhesives, printing inks, textile sizes and protective colloid. It acts as a stabilizer in foods. It is also employed in pharmaceuticals as a suspending agent and excipients for tablets. It is used as viscosity modifiers to stabilize the emulsions. It is used as a lubricant in artificial tears and it is used to characterize enzyme activity from endoglucanases.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
