What is carboxymethylcellulose?

CMC, carboxymethylcellulose or cellulose gum is a cellulose derivative with carboxymethyl groups CH₂-COOH attached to some hydroxyl groups of glucopyranose monomers that form the backbone of cellulose.

carboxymethylcellulose can be used mainly as its sodium salt and as sodium-carboxymethylcellulose. It used to be marketed under the Tylose brand.

carboxymethylcellulose is a water-soluble salt that can be produced in large commercial quantities without any refining for use in detergents, drilling fluids and the paper industry. In higher purity, cumin is also used as a food additive.

Production and synthesis of carboxymethylcellulose

carboxymethylcellulose is produced by an alkaline reaction catalyzed by cellulose with chloroacetic acid. Polar carboxylic groups (organic acids) dissolve cellulose and are chemically reactive.

After the initial reaction, the resulting mixture produces approximately 60% CMC and 40% salt (sodium chloride and sodium glycolate).

An additional purification process is used to remove these salts to synthesize pure CMC used for food and pharmaceutical applications. A “semi-pure” grade is also produced, which is commonly used in paper programs such as archiving documents.

The functional properties of CMC depend on the degree of cellulose structure replacement (ie, several hydroxyl groups have participated in the substitution reaction) as well as the length of the cellulose backbone chain and the degree of clustering of the cyanide substitutes.

Application of carboxymethylcellulose

Due to the hydrophilic properties, high viscosity and adhesive performance, CMC has a wide variety of applications.

• Building: CMC is used in most cement and building materials as a stabilizing and hydrophilic agent. Improves the dispersion of sand in cement and intensifies the effect of its adhesion. In addition, it is used as an adhesive in upholstery.
• Detergents: Detergent industry is the largest consumer of CMC. carboxymethylcellulose compounds are often used in soaps and detergents.
• Paper Industry: Coating with cotton wool reduces the consumption of wax in paper and wax cardboard and ensures less wax penetration into the paper.
• Agriculture: In pesticides and water-based sprays, CMC is used as a suspending agent. It is also used as an adhesive to attach insecticides to plant leaves. CMC is sometimes used as an aid in the destruction of certain fertilizers that are highly polluting.
• Gluing: CMC is added to different combinations of adhesives with different applications. Widely used in the leather industry.
• Painting: CMC is used in oil paints and varnishes. It acts as a thickener and suspends the pigment in the liquid.
• Oil Industry: Raw or purified CMC is used in the drilling sludge as a colloidal thickener and is used to prevent fouling when removing the drill from the hole.
• Plastics and ceramics: The main application of CMC in the plastics industry is to help increase the viscosity of plastics such as latex.
• Textile: Raw CMC is used as a size factor for the fabric. CMC is also used in combination with starch in washing operations.
• Pharmacology: CMC is used to cover tablets of high purity and low viscosity. CMC is insoluble in the acidic environment of the stomach but soluble in the main environment of the intestine.
• Food Industry: CMC vinegar is used in food as an adjuvant in ice cream, cream and dairy products, as an adjuvant for the formation of gels in gelatins and puddings, and as a thickener in salad dressings.

Dangers of carboxymethylcellulose

CMC has been shown to cause intestinal inflammation, alter microbiota, and has been shown to trigger inflammatory bowel diseases such as ulcerative colitis and Crohn’s disease.
