Name of Products : Carboxymethyl Cellulose Sodium (sodium CMC, SCMC, CMC, CMC-NA) and Carboxymethyl Starch Sodium (CMS)
Molecular Formula : C6H7O2 (OH)2OCH2COONa
CAS NO. 9004-32-4
H.S. Code : 39123100
Chemical Properties : CMC is a kind of cellulose ether with anion contour’s high molecular structure. It has no smell, no taste and no toxicity. The white to off-white powder and graininess can be easily melt in water and become colloidal solution, but it can’t melt in alcohol, ether, acetone and other organic solvent.
