Carboxymethyl cellulose (CMC) is a water-soluble cellulose ether that is widely used in various industries such as food, pharmaceuticals, cosmetics, and papermaking. In papermaking, CMC is used as a paper coating agent, binder, and additive to improve paper strength, surface properties, and printability.

One of the main applications of CMC in papermaking is as a surface sizing agent, which is a process that involves applying a thin layer of CMC solution onto the paper surface to improve its surface properties. CMC can increase the paper's resistance to water and oil, enhance its smoothness, and improve its printability. CMC can also improve the paper's strength by increasing the bonding between the paper fibers.

In addition to its role as a surface sizing agent, CMC is also used as a binder in paper coatings. It can be used to bind pigments, fillers, and other additives to the paper surface, which can improve the paper's optical and surface properties. CMC can also be used as an additive to improve the retention of fillers and pigments in the paper, which can reduce the amount of these materials needed and lower production costs.

Overall, the use of CMC in papermaking can result in a higher-quality paper product that is more resistant to water and oil, has improved printability, and is more cost-effective to produce.
