Carboxymethyl cellulose (abbreviated as CMC) is a kind of cellulose derivative which is obtained by chemical modification of natural cellulose. Because it does not dissolve in water, so it is commonly used sodium salt, sodium carboxymethyl cellulose (abbreviated CMC-Na), is still referred to as CMC. CMC is white or yellowish powder, odorless, moisture, not soluble in ethanol, soluble in water, forming a transparent colloid in the water, many uses of CMC, according to the decision of this nature.

1. In Detergent powder, it is used as a soil suspension polymer designed to deposite onto cotton and other cellulosic fabrics, creating a negatively charged barrier to soils in the wash solution.
2. CMC is used in food as a viscosity modifier or thickener and to stabilize emulsions in various products including ice cream.
3. It is also a constituent of many non-food products, such as toothpaste, laxatives, diet pills, water-based paints, textile sizing, and various paper products.
4. In the oil-drilling industry, as an ingredients of drilling mud, where it act as a viscosity modifier and water retention agent.
5. Sometimes, it is used as an electrode binder in advanced battery applications.
