Sodium Carboxymethyl Cellulose (CMC) is an anionic water soluble polymer derived from cellulose. It is odourless, tasteless and nontoxic. It has good water solubility, stickiness, emulsification, diffusibility, enzyme resistance and thermal stability. The transparency of its solution gets corresponding improvement with the increase of substitution degree. The water solubility of CMC presents neutral or light alkalescence. It will precipitate when meeting the metallic ion with more thanbivalence.

CMC is an anionic, biodegradable and linear polymer cellulose ether. It is one of the most versatile of water-soluble hydrocolloids and has a number of important properties including solubility, rheology, adsorption on surfaces, etc. Apart from these, viscosity and the degree of substitution (DS) are the two major properties of CMC that determine its functionality.

General information

 

CMC sample  

CAS No: 9004-32-4
E-No.: E466

Melting point: > 300 °C
Browning temperature: 227 °C
Auto ignition temperature: > 370 °C

Applications
CMC is used primarily in foods, drugs and cosmetics as a viscosifier, emulsion stabilizer, thickener and improve texture. The main applications of technical grade are in textile warp sizing and paper processing. CMC is also used in detergent as a antiredeposition agent, textile warp-sizing aid, adhesives, latex paints and polishes.
