Carboxy methyl cellulose (CMC) or cellulose gum is a cellulose derivative with carboxymethyl groups (-CH2-COOH) bound to some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone. It is often used as its sodium salt, sodium carboxymethyl cellulose.

It is synthesized by the alkali-catalyzed reaction of cellulose with chloroacetic acid. The polar (organic acid) carboxyl groups render the cellulose soluble and chemically reactive. The functional properties of CMC depend on the degree of substitution of the cellulose structure (i.e., how many of the hydroxyl groups have taken part in the substitution reaction), as well as the chain length of the cellulose backbone structure and the degree of clustering of the carboxymethyl substituents.

Main applications
Widely used in the petroleum industry as well-digging mud treatment agent, synthetic detergent, organic detergent aid, textile printing and dyeing sizing agent, water-soluble gelatinous viscosifier for daily-use chemical products, viscosifying and emulsifying agent for the pharmaceutical industry, thickening agent for the food industry, adhesive for the ceramic industry, industrial paste, sizing agent for the paper industry, etc. It is used as a flocculant in water treatment, mainly for wastewater sludge treatment, and can improve the solids content of the filter cake.

Sodium carboxymethyl cellulose is also a kind of thickening agent, due to its own good functional properties make it in the food industry has been widely used, it also to a certain extent to promote the rapid and healthy development of the food industry. For example, because it has a certain thickening and emulsifying effect, it can be used to stabilise yoghurt drinks and increase the viscosity of the yoghurt system; because it has a certain hydrophilic and rehydrophobic effect, it can be used to improve the edible quality of pasta such as bread and buns, extend the shelf life of pasta products and enhance the taste; because it has a certain gel effect, it is conducive to the better formation of food gel, so it can be used in the manufacture of jelly and jam It can also be used as an edible coating material, which can be combined with other thickeners and applied to the surface of some food products to maximise freshness and, as it is an edible material, has no adverse effects on human health. Therefore, edible grade CMC-Na is an ideal food additive and is very commonly used in food production in the food industry.
