  • Sodium Carboxymethyl Cellulose (CMC) is a kind of white grain and fibrous powder which are nontoxic and easy to absorb water. It has good water solubility, stickiness, emulsification, diffusibility, enzyme resistance and thermal stability. The transparency of its solution gets corresponding improvement with the increase of substitution degree. The water solubility of CMC presents neutral or light alkalescence. It will precipitate when meeting the metallic ion with more than bivalence.
  • CMC was developed in Germany during World War I as a substitute for gelatin. During the 1930s, CMC was used to eliminate redeposition of soil
    on fabric during washing and rinsing. There was also interest in the production of CMC after the war. Kalle and Co. in Wiesbaden-Biebrich
    produced it in the late 1930s. Herculus then developed a commercial process in 1943.
  • The product is the sodium salt of a carboxymethyl ether of cellulose, which has been partially hydrolyzed by enzymatic treatment with food-grade Trichoderma reesei cellulase. The total content of mono- and disaccharides does not exceed about 7.5%. 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), and also on the chain length of the cellulose backbone structure.
  • CMC is an anionic, biodegradable and linear polymer cellulose ether. It is one of the most versatile of water-soluble hydrocolloids and has a number of important properties including solubility, rheology, adsorption on surfaces, etc. Apart from these, viscosity and the degree of substitution (DS) are the two major properties of CMC that determine its functionality.
  • CMC is more tolerant to the presence of ethanol than most other food gums. This makes cellulose gum useful for cordials and other low alcohol content beverages which require optical transparency. CMC will give a synergistic viscosity increase with other hydrocolloids such as guar or locust bean gum. The availability of cellulose gum in different viscosity grades, particle sizes, special rheological grades, and combinations thereof permits tailor-made application of CMC to many different food systems.
  • CMC is used in food science as a viscosity modifier or thickener, and to stabilize emulsions, for instance in ice cream. 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, and various paper products. They have high viscosity, are not toxic, and are generally non-allergenic. CMC is used as a lubricant in non-volatile eye drops (artificial tears). Sometimes it is methylcellulose (MC) which is used, but its non-polar methyl groups (-CH3) do not add any solubility or chemical reactivity to the base cellulose.
  • Cellulose from waste of mulberry paper was modified to be carboxy methyl cellulose (CMC) by adding isopropyl alcohol and sodium hydroxide (NaOH). Tensile strength and percent elongation of CMC films increased as NaOH concentration in CMC synthesis increased. However, when the level of NaOH concentration was 60%, film could not be formed due to CMC solution had too low viscosity. Therefore, the best level of NaOH concentration in CMC synthesis was 50% NaOH which provided the best mechanical properties.
  • Demand for purified CMC is affected by demand from purchasers who use the product for a variety of end uses. Fluctuations in the consumption of purified CMC were affected primarily by fluctuations in apparent consumption of purified CMC by oilfield purchasers. The annual demand for CMC in Russia and other CIC countries is about 60-65K mt, while Russia consumes 6K mt/y. Currently, Russia features 13 facilities manufacturing Na-CMC of various grades. 
  • Aqualon is the only U.S. producer of purified CMC, and the firm accounted for all known U.S. production of the purified CMC in 2003. Major purchasers of purified CMC consist of firms in the food, personal care, cosmetics and pharmaceuticals, paper and board, and oilfield industries. Prices for purified CMC vary by specification and end use. Generally, purified CMC for food and personal care applications command a higher price when compared to purified CMC for paper and oilfield applications.
  • Aqualon had the ability to respond to changes in demand with changes in the quantity of shipments of U.S.-produced purified CMC to the U.S. market during much of January 2001-March 2004. Noviant Finland sold its purified CMC principally to third-country export markets, secondarily to its home market, and the remainder to the U.S. market during January 2001-March 2004; this shipment pattern was projected to continue in 2004 and 2005.
