Sodium Carboxymethyl Cellulose (CMC) is a water-soluble cellulose ether derived from natural cellulose through chemical modification. It appears as white to off-white powder or granules, and functions as a thickener, humectant, binder, emulsifier, disintegrant, and biomaterial carrier. This versatile compound is widely used across food, daily chemicals, pharmaceuticals, petroleum, textile dyeing, and other industries.
