SUNRAY Sodium Carboxymethyl Cellulose (CMC), CAS No. : 9004-32-4.

sodium carboxymethyl cellulose (scmc or cmc) or cellulose gum is an anionic water soluble polymer; it is derived from cellulose, which is made water soluble by a chemical reaction. The water solubility is achieved by introducing carboxymethyl groups (-ch2-cooh) along the cellulose chain, which makes hydration of the molecule possible.

the chemical name of scmc is sodium salt of carboxymethyl ether of cellulose.

cas number: 9004-32-4.

chemical formula:  [c6h7o2 (oh) x (och2coona) y] n
where n = degree of polymerization, x = 1.50 to 2.80, y = 0.2 to 1.50, x + y = 3.0
y = degree of substitution

cmc is a white to creamish coloured powder consisting of very fine particles, fine granules. It is odor less and tasteless. It is a hygroscopic powder readily dissolves in water to form colloidal solution. It is insoluble in many organic solvents such as methanol, ethanol, propanol and acetone and so on.
