Sodium carboxymethyl cellulose (Na-CMC or cellulose gum) is the most widely used and most frequently used type of anionic cellulose ether. It is a white fibrous or granulated powder. Odorless, tasteless, non-toxic, hygroscopic, easily soluble in both hot and cold water, obtained by chemical modification of natural fibers featured by unusual and extremely valuable physical and chemical properties. The main raw material to process CMC is refined cotton and wood pulp.
Sodium carboxymethyl cellulose has superior functionality in terms of adhesive, thickening, stabilizing, emulsifying, water-retaining, tenacity strengthening, suspension, film-forming, etc, is widely used in various industries, such as food and beverage processing, ceramic, pharmaceutical, toothpaste, oil drilling, paper making, textile, and dyeing, etc. In the food industry, CMC can be compounded with other food stabilizers and emulsifiers to complement each other, strengthen each other’s effect and reduce the production cost.
