What is CMC & PAC

Sodium carboxymethyl cellulose (CMC) is usually made by the reaction of natural cellulose and caustic soda and a chlorine acetic acid made after the production of an anionic polymer.

It is cellulose carboxymethyl ether sodium salt, an anionic cellulose ether, white or milky white fibrous powder or granules. CMC can be widely used in various industries, for example Food, Pharm, Ceramic, Textile, Paint, Paper-making, Detergent etc.

The international community to this new type of modified CMC also known as “polyanionic cellulose (abbreviated PAC)”. PAC is typically used in Oil drilling industry.

THE FUNCTION OF CMC IN THE DETERGENT INDUSTRY
Detergent grade CMC is a white or slightly yellowish, almost odorless and tasteless hydroscopic powder, consisting of very fine particles, fine granules or fine fibers. It has an efficiency of suspension, preventing secondary-precipitation, retaining moisture, stability, thickening, with peculiarities of fast-dissolve, utilization-convenience.

CMC also has emulsifying and protecting colloid properties. It plays a role in preventing dirt from reattachment during the washing process. It enables the fabric after washing to be soft and reduce skin irritation.
In making soap, adding an appropriate amount of Detergent Grade CMC helps to greatly improve the quality of soap. Its mechanism and advantages are the same as the application in synthetic detergent. Also, CMC enables soap to be pliable and flexible and thus convenient for pressing and processing.
