Product Description
CAS No.: 9000-11-7
Molecular Formula: [C6H7O2(OH)2CH2COONa]n
Property:
Carboxymethyl Cellulose Sodium (CMC-Na) is a cellulose derivative obtained by chemically modificating the natural cellulose. It is one of the most important water soluble polymers with many advantages that other natural or synthetic glues do not have.
CMC is white and flowing fine powder. It is tasteless, smelless, mould-proof, non-toxic, non-flammable and easily dissolved in water to become transparent viscose solution.
CMC solution has good properties of thickening, adhering, emulsifying, and stabilizing. Membrane forming, moisture-holding, shape-holding, dispersing and anti-enzyme. The solution of CMC can be mixed with dissolvable animal glues, glycerin, sobbitol, Arabic gum, pectin, xanthic gum and dissolvable starch.
