Carboxymethyl cellulose, referred to as CMC, also known as sodium carboxymethyl cellulose, is a product obtained by carboxymethylation of cellulose, and carboxymethylation reaction is a kind of etherification technology. The appearance of carboxymethyl cellulose is white or yellowish powder or flocculent fiber powder. Organic solvents such as ether and acetone. Carboxymethyl cellulose belongs to anionic cellulose ether, and is the product with the widest application and the largest production and sales volume among cellulose ethers.
Carboxymethyl cellulose is made from cellulose, adding alkali, such as sodium hydroxide, to make alkali cellulose through alkalization reaction, and then adding monochloroacetic acid for etherification reaction. Carboxymethyl cellulose has the functions of thickening, bonding, film forming, water retention, emulsification, suspension, and dispersion, and can be used as a thickener, adhesive, film forming agent, water retaining agent, emulsifier, suspending agent, Agents, etc., are widely used in petroleum, plastics, papermaking, textiles, printing and dyeing, building materials, daily chemicals, medicine, food and other industries.
According to the "2020-2024 In-Depth Market Research and Investment Strategy Suggestion Report on Carboxymethyl Cellulose Sodium Industry" released by Xinsijie Industry Research Center, from 2016 to 2019, the global carboxymethyl cellulose market value has a compound annual growth rate. It is 2.9%, and the market value in 2019 is about 146.28 billion US dollars. The global application of carboxymethyl cellulose is still expanding, and it is expected to maintain a rapid growth rate in the next five years. By 2024, the market value will reach about 163.12 billion US dollars, with an average annual compound growth rate of 2.2%.
From the perspective of the global carboxymethyl cellulose market segment, the food sector accounts for the largest demand, reaching 24%; followed by the detergent sector, accounting for 21%; the oil drilling sector ranks third, accounting for 19% of the demand; The field of papermaking ranks fourth, accounting for 12% of demand; the field of textiles ranks fifth, accounting for 8% of demand; the field of cosmetics ranks sixth, accounting for 6% of demand; other fields account for 10% of demand. Among them, the food sector is the market segment with the largest demand and fastest growth for carboxymethyl cellulose.
In the overseas market, carboxymethyl cellulose manufacturers mainly include Dow Chemical, Ashland, CP Kelco, Nimberdi, AkzoNobel, Daicel, and Nippon Paper.
Industry analysts from Xinsijie said that the global carboxymethyl cellulose market is developing well, but there is also a risk of being replaced. In the high-end market, polyanionic cellulose has better physical and chemical properties and gradually forms a substitute for carboxymethyl cellulose. . The high-end market is an important area for the carboxymethyl cellulose industry to increase the added value of products and enhance corporate profitability. In the future, the industry needs to continuously improve production technology and technology, develop in the direction of high performance and high stability, and compete with other products for market share.
