  • What is sodium carboxymethyl cellulose (Na CMC)?
  • Cite this: ACS Appl. Polym. Mater. 2019, 1, 3, 344–358 Sodium carboxymethyl cellulose (Na CMC) is used for its thickening and swelling properties in a wide range of complex formulated products for pharmaceutical, food, home, and personal care applications, as well as in paper, water treatment, and mineral processing industries.
  • Does CMC require high purity?
  • It is commonly said that CMC requires high purity for pharmaceutical or food products, and this is defined by the presence of minimal by-products (sodium glycolate, sodium chloride, and excess unreactive alkali) and unconverted cellulose in the produced CMC mixture.
  • What is sodium carboxymethylcellulose?
  • Sodium carboxymethylcellulose [sodium O- (carboxymethyl)cellulose] is a water-soluble cellulose ether produced by reacting alkali cellulose with sodium monochloroacetate. CMC, as it is commonly called, is versatile in its ability to control the rheology and viscosity of aqueous systems and to form strong, tough films.
  • Can carboxymethyl cellulose be analyzed with an eluent of sodium nitrate or sulfate?
  • Measuring the molecular weight distribution of carboxymethyl cellulose with an eluent of sodium nitrate or sodium sulfate is possible. Stable analysis can be achieved with a less corrosive eluent. The integrated HPLC system is not dedicated to gel-filtration chromatography (GFC), but also utilized for other purposes.
