CMC--Carboxymethyl Cellulose sodium

CMC (Sodium Carboxymethyl Cellulose) Molecular Formula: C6H7O2 (OH)2OCH2COONaCAS NO. 9004-32-4H.S. Code: 39123100Chemical Properties: CMC is a kind of cellulose ether with anion contours 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 cant melt in alcohol, ether, acetone and other organic solvent.
