Sodium carboxymethyl cellulose (CMC), also known as carboxymethyl cellulose. It is a highly polymerized fiber ether prepared by chemically modifying natural cellulose. Its structure is mainly composed of D-glucose units connected by β_(14) glycosidic bonds.

CMC is white or creamy white fibrous powder or granule, density 0.5-0.7g/cm3, almost odorless and tasteless, with hygroscopicity.

It can be seen from the structural formula that the hydrogen (Na+) on CMC is easily separated in an aqueous solution (usually in the form of sodium salt). Hence, CMC exists in the form of an anion in an aqueous solution.

In recent years, sodium carboxymethyl cellulose has developed significantly in quality, yield, variety, and technology, and its use has gradually been promoted.

Phosphate, the salt of phosphoric acid, is one of the natural ingredients of almost all foods. As an important food ingredient and functional additive, it is widely used in food processing.
