Carboxymethyl cellulose sodium (CMC) is a chemically modified derivative of cellulose, the most abundant polymer in nature, tailored to be soluble in water. This modification involves attaching carboxymethyl groups (-CH2-COOH) to some of the hydroxyl (-OH) groups on the cellulose chain, thereby introducing negative charges that increase its solubility. CMC serves a wide array of purposes across various industries due to its unique properties. It acts as a thickener, stabilizer, and emulsifier in food production, improves texture and extends shelf life. In pharmaceuticals, CMC is utilized as a binder and excipient, facilitating tablet formation and drug delivery. Additionally, its applications extend to the cosmetic industry as a thickening agent in lotions and shampoos, and in paper production, it enhances paper strength and smoothness. Its biocompatibility and non-toxic nature make CMC an indispensable component in many formulations.

Carbohydrates are organic compounds composed of carbon, hydrogen, and oxygen, typically in a 1:2:1 ratio. They primarily function as energy sources and structural materials in organisms. The polymers of carbohydrates are polysaccharides, which are long chains of monosaccharide units linked by glycosidic bonds. Common examples include starch, glycogen, and cellulose. Starch, found in plants, serves as an energy reserve, whereas glycogen, found in animal cells, serves a similar purpose. Cellulose, another polysaccharide, provides structural support in plant cell walls. Differences in the glycosidic linkages and the monosaccharide units result in the diverse functions and properties of these polysaccharides.
