What Is Cellulose Gum (CMC)?

Cellulose Gum – Carboxymethyl Cellulose (CMC), or cellulose gum is an abundant and natural polysaccharide found in all plants.  Cellulose gum is a type of cellulose-based water-soluble gum. Cellulose gum has been used as a thickening and stabilizer in food for over 50 years. Its most common applications are in instant beverages, where it adds texture, baked goods, where it inhibits staling, and ice cream, where it prevents the production of ice crystals caused by repeated freezing and thawing.

Manufacture and Types

Wood pulp and pure cotton cellulose are used to make cellulose gum. There are two types of cellulose gum: industrial and food grade. Technical-grade and semi-purified cellulose gum are two types of industrial-grade cellulose gum. Technical-grade cellulose gum (or crude CMC) has a purity of less than 80%; semi-refined cellulose gum has a purity of between 80% and 95%; and purified cellulose gum has a purity of more than 99.5 percent. Only pure cellulose gum is suitable for consumption.

Uses of Food Grade

Because of its ability to maintain pH, cellulose gum can be found in a number of protein drinks. It's also in fondants, icing, and syrup, where it helps to balance out the sweetness. Because it prevents the production of ice crystals, cellulose gum is used in frozen desserts and ice cream. Frozen doughs, salad dressings, processed cheese products, meat items, and juice concentrates are all sources of cellulose gum. 
Essentially, cellulose gum is a highly versatile and cost-effective substance. There are numerous applications for this product, however the following are the most common:
Food

Cellulose gum is mostly utilized in food as a thickening and stabilizing ingredient. This product is mostly found in the following places:
–        Milk and Milk Drinks
–        Ice Cream

 

Cellulose gum is used in ice cream to make water, fat, and protein form a homogenous, dispersed, and stable mixture, avoid the formation of ice crystals, and provide a fine and smooth taste as well as good formability. The use of cellulose gum in ice cream can significantly reduce the cost of production.
–        Syrups
–        Yogurt
–        Baked Goods and more

Uses of Industrial grade
The industrial grade cellulose gum is utilized in oil drilling, household items, and a variety of personal care products, in addition to food. The precise applications of this substance vary depending on the application, however it is most commonly employed to thicken and stabilize the chemicals already present in these products. Cellulose gum has become one of the most frequent materials found in both food and household items because it mixes quickly in hot or cold water, adds texture, and stabilizes the pH balance.
Daily Chemicals
In addition to oil well drilling, cellulose gum is used in personal care products (toothpaste, hair gel, shampoo, lotion and ointment). The cellulose gum used in the textile sector can be used to make paper. Crude cellulose gum is used in small-scale laundry detergents.
Printing & Dyeing

Carboxymethylcellulose is used in the paint and resin industry as a viscosity control agent in emulsion paints, which has a favorable effect on brush movement. In soluble paints, it is used to fill pores in porous surfaces in gypsum walls, etc., before applying paint and oil. It is also a water retainer and absorber, a paint retainer, a layer builder, a particle suspender, a stabilizer, a thickener and a holder.
Oil Drilling

CMC is a water absorber and retainer, as well as a well wall sealer, soil suspender, and psychological thickening, and it improves the quality of drilling mud and reduces fluid loss.
Papermaking and more
In the paper-making process, this material increases the anti-brittleness, tensile strength, and hardness of the paper by increasing its resistance to abrasion and surface uniformity. It's also a component of the adhesive layer, concentrating, raising strength, smoothing and polishing the surface, and strengthening the surface's flexibility against folding. This material can be utilized as a viscosity control agent in corrugated cardboard manufacturing, as well as a stabilizer for starch pastes and adhesives.
Pharmaceutical uses of Carboxymethyl Cellulose

Sodium carboxymethyl cellulose is used in the pharmaceutical industry as an injection emulsion stabilizer, as well as adhesion and film-forming agents for tablets. Sodium carboxymethyl cellulose has been found to be a safe and effective carrier of anticancer drugs in animal studies.


Film-forming materials can be made with sodium carboxymethyl cellulose.In animal models, the film was proven to be effective in preventing wound infection. It has no discernible differences from gauze wound dressings, however it clearly outperforms gauze dressings in terms of wound interstitial fluid exudation and wound healing. It can also aid to reduce edema and wound stimulation after surgery.

The film agent made from polyvinyl alcohol (PVA), sodium carboxymethyl cellulose (CMC), and carboxyl polymethyl (CP) in the ratio of 3:6:1 is the optimal prescription. Both the adhesive ability and the rate of release can be changed. Sustained-release film agents attach to mucosa considerably more efficiently as a result of the preparation, extending their resistance length and increasing their efficacy.
Because sodium carboxymethyl cellulose has been shown to be more successful than sodium hyaluronate at minimizing postoperative adhesion, it may be a viable option for preventing peritoneal adhesion. Sodium carboxymethyl cellulose can be used to extend the resistance period of cancer drugs in liver tumors, augment antineoplastic activity, and improve treatment efficacy in patients with liver cancer using transcatheter arterial perfusion. Animal medicine also makes extensive use of sodium carboxymethyl cellulose.
