Carboxymethyl cellulose (CMC) CAS 9004-32-4 or cellulose gum is a cellulose derivative with carboxymethyl groups (-CH2-COOH) bound to some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone. It is often used as its sodium salt, sodium carboxymethyl cellulose.
Sodium carboxymethylcellulose ( CAS 9004-32-4) is white powder. 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.

Application
Food grade:
CMC can be used for the surface treatment of vegetables, fruits, eggs and tea, to form a thin film on its surface,
to maintain the original color and flavor and extend shelf life.
Toothpast and Medicine:
Used to repair teeth, to make a laxative, hemostatic agents, frame adhesive. The base material can also be used as
a variety of ointment, tablet binders, X-ray fluoroscopy with barium sulfate, titanium dioxide dispersing agent.
Drilling grade:
CMC preparation of drilling mud, make the sidewall to form a thin caine, low permeability filter cake, reducing the amount of water on loss.
Tobacco:
CMC With good adhesion, film build and maintain water performance Effectively reduce the tar content of tobacco.
Itself non-toxic odorless and has a burn performance.
Paper-making:
Paper coloring process, the CMC help control the paste fluidity. Improve the paper between the internal fiber viscous
state, to improve the paper folding.
Texitle industry:
CMCUsed in the textile industry, printing paste material can be used as fabric finishing agents and finishing industry.
CMC as fabric finishing agent instead of the starch slurry, reducing the fabric sizing and desizing Pollution of the
environment, to form a thin film on the fabric fibers ;
Packaging
