Sodium carboxymethylcellulose has a wide range of applications and the industry needs to be transformed and upgraded.

Sodium carboxymethyl cellulose (CMC-Na) is a carboxymethylated derivative of cellulose. It is an anionic polymer compound usually produced by reacting natural cellulose with caustic alkali and monochloroacetic acid. Its properties are odorless, hygroscopic, white fibrous or granular powder, and it is the most important ionic cellulose glue.

Carboxymethyl cellulose sodium can be divided into alkaline carboxymethyl cellulose sodium and neutral carboxymethyl cellulose sodium according to different pH levels; according to different viscosity, it can be divided into low viscosity carboxymethyl cellulose sodium, medium viscosity carboxymethyl cellulose sodium Cellulose sodium and high viscosity carboxymethyl cellulose sodium; according to different application fields, it can be divided into petroleum grade carboxymethyl cellulose sodium, industrial grade carboxymethyl cellulose sodium, food grade carboxymethyl cellulose sodium and others.

Sodium carboxymethylcellulose is widely used in food, ceramics, papermaking, medicine and other fields. Food-grade sodium carboxymethyl cellulose has excellent performance and is harmless to the human body. It is an ideal food additive that can increase the viscosity of lactic acid drinks, improve the taste of bread and other flour foods, and extend the shelf life. It can also be used for Food preservation, manufacturing jelly, etc. In the industrial field, sodium carboxymethylcellulose can be used to make synthetic detergents, textile printing and dyeing sizing agents, adhesives for the ceramic industry, sizing agents for the paper industry, and flocculants for wastewater treatment.

According to the“In-depth Market Research and Investment Strategy Suggestions Report on Sodium Carboxymethylcellulose Industry 2023-2027” released by the Industrial Research Center It shows that with the continuous expansion of downstream fields and the growing market demand, my country’s sodium carboxymethylcellulose market continues to expand and is expected to exceed 20 billion yuan in 2025.

At present, the preparation methods of sodium carboxymethyl cellulose mainly include the water medium method using water as the reaction medium and the solvent method using organic solvents as the reaction medium. The water medium method is mainly used to produce medium and low-grade alkaline sodium carboxymethyl cellulose. The solvent method is mainly used to produce medium to high-grade neutral sodium carboxymethyl cellulose.

The entry threshold for industrial-grade sodium carboxymethylcellulose is low, but the production of food-grade sodium carboxymethylcellulose has high technical barriers and has high requirements for production equipment and production technology. At present, most carboxymethylcellulose sodium manufacturers in my country are still in the mid- to low-end market, and the food-grade carboxymethylcellulose sodium market still has considerable room for development. At present, sodium carboxymethyl cellulose manufacturers on the market include Finland’s Noviant Company, Japan’s Decil Company, Netherlands’ AkzoNoble Company, Zibo Heilan Chemical, Changshu Weiyi Technology, Tianya Chemical, Huaihua Aosheng Technology, etc.

Industry analysts said that with the development of my country’s economy, the downstream industry of sodium carboxymethylcellulose continues to expand and the market demand increases. The production scale of sodium carboxymethylcellulose in my country continues to expand. At present, domestic carboxymethylcellulose sodium production enterprises are mainly concentrated in the mid-to-low-end market. Relevant enterprises need to continuously improve production processes, improve production technology, promote industrial transformation and upgrading, and develop towards the high-end market.
