CMC is used in food science as a viscosity modifier or thickener, and to stabilize emulsions in various products including ice cream. As a food additive, it has E number E466. It is also a constituent of many non-food products, such as K-Y Jelly, toothpaste, laxatives, diet pills, water-based paints, detergents, textile sizing and various paper products.

Insoluble microgranular carboxymethyl cellulose is used as a cation-exchange resin in ion-exchange chromatography for purification of proteins.Presumably the level of derivatization is much lower so that the solubility properties of microgranular cellulose are retained while adding sufficient negative charged carboxylate groups to bind positively charged proteins.CMC is also used in ice packs to form a eutectic mixture resulting in a lower freezing point and therefore more cooling capacity than ice.

CMC is also used in the oil drilling industry as an ingredient of drilling mud, where it acts as a viscosity modifier and water retention agent. Poly-anionic cellulose or PAC is derived from CMC and is also used in oilfield practice.The functional properties of CMC depend on the degree of substitution of the cellulose structure as well as the chain length of the cellulose backbone structure and the degree of clustering of the carboxymethyl substituents.

CMC is used as a food additives, emulsifier, firming agent, gelling agent, glazing agent, humectant, stabilizer and thickener. It is coded as E466 by the European Union. It is used in drink flavorings, cordials, flavored toppings, breakfast cereals, snack bars, infant formula, frozen cakes, fruit twists, fillings, bases & toppings, instant pasta & sauces, ice creams, icings, confectionery, cottage cheese and cream cheese spread.
