Product Introduction:
Sodium Carboxymethyl Cellulose, commonly referred to as CMC for short, is a water-soluble cellulose derivative produced through chemical modification from natural cellulose and has excellent physical and chemical properties. CMC usually appears as white to light yellow powdered material that has strong hygroscopicity with neutral or alkaline conditions while acidic environments cause viscosity to decrease over time. Furthermore, long-term heating above 80degC will cause viscosity decrease.
Preparation of Sodium Carboxymethyl Cellulose involves two key steps: alkalization and etherification. First, cellulose reacts with sodium hydroxide under alkaline conditions to produce alkali cellulose; subsequenty, alkali cellulose undergoes an etherification reaction with monochloroacetic acid to finally become Sodium Carboxymethyl Cellulose. Chemical structures give gelatin its distinctive properties, making it useful in numerous fields. Food industries commonly employ gelatin as thickener, stabilizer and emulsifier to enhance texture, taste, shelf life extension of products such as ice cream, jam or beverages by preventing crystal formation, maintaining uniformity or stabilizing beverages.
Sodium Carboxymethyl Cellulose plays an integral part in the pharmaceutical field. It can be used to prepare adhesives and disintegrants for tablets, as a sustained-release carrier to facilitate better drug release into the body, with good biocompatibility – causing no adverse reactions in human beings -and daily chemical use in toothpaste, shampoo and cosmetic products for thickening, stabilization and moisturization properties; while industrial areas like papermaking textiles and ceramics often employ it to enhance strength of papermaking process printing/dyeing effects/ molding properties while molding properties of ceramics.
Sodium Carboxymethyl Cellulose’s wide application also draws strength from its environmental characteristics. As an offshoot of natural cellulose, it poses no serious pollution concerns when in use and biodegrades quickly – its prospects of usage only look brighter as more people pay more attention to sustainability development issues.

In the food industry, SCC is an important additive. As a thickener and stabilizer, it is widely used in products such as ice cream, jam, jelly and beverages. In ice cream, it can effectively control the growth of ice crystals and make the taste more delicate; in jam and jelly, SCC helps to form a good gel structure and maintain a stable shape; in beverages, it prevents pulp from settling and maintains a uniform suspension state.
In the pharmaceutical field, SCC is mainly used in pharmaceutical preparations. As a binder and disintegrant for tablets, it can improve the formability and release properties of drugs. In ointments and creams, Sodium Carboxymethyl Cellulose acts as a thickener and stabilizer to keep the drug in a uniform paste state, prolong the drug’s residence time on the skin, and thus improve the drug’s efficacy. In addition, it can also be used in sustained-release preparations to achieve a long-lasting effect of the drug by controlling the drug release rate.
In the daily chemical industry, Sodium Carboxymethyl Cellulose is an important ingredient in products such as toothpaste, shampoo, and shower gel. In toothpaste, it keeps the toothpaste in a stable paste form and is easy to extrude; in shampoo and shower gel, it acts as a suspending agent to evenly disperse insoluble particles and prevent precipitation, while providing good foam and lubricity to enhance the consumer’s experience.
In the industrial field, Sodium Carboxymethyl Cellulose is also widely used. In oil extraction, it acts as a thickener and fluid loss reducer for drilling mud, which can improve the stability and rheology of the mud, prevent well wall collapse, and improve drilling efficiency. In the textile printing and dyeing industry, Sodium Carboxymethyl Cellulose, as the main component of printing paste, can improve the clarity and color vividness of printed patterns and reduce penetration. In the papermaking industry, it is used as a surface sizing agent and coating adhesive to improve the strength, smoothness and printing adaptability of paper.
In addition, Sodium Carboxymethyl Cellulose also has good biocompatibility and degradability, which meets environmental protection requirements. It is non-toxic, harmless, safe for human body and environment, so it has been widely used in food, medicine and daily chemicals. With the development of science and technology, its application scope will continue to expand, providing efficient and environmentally friendly solutions for more industries.
First, sodium carboxymethyl cellulose has excellent thickening properties. It is able to significantly increase the viscosity of the solution at low concentrations while maintaining the transparency and stability of the solution. This characteristic makes it widely used in food, medicine, daily chemical and industrial fields, for example, as a thickener in food to improve taste, and in paint to improve rheological properties.
Secondly, sodium carboxymethyl cellulose has good biocompatibility and degradability. It is derived from natural cellulose, non-toxic and harmless, and meets the safety standards of food and drug production. In addition, it can degrade under natural conditions without causing pollution to the environment, which makes it more competitive in the context of increasingly stringent environmental requirements.
Sodium carboxymethyl cellulose also has excellent suspension stability and emulsification properties. It can effectively encapsulate and stabilize suspended solid particles, prevent them from settling or agglomerating, while reducing the surface tension between the liquids and improving the stability of the oil-water mixture. These properties make it ideal for applications in food, cosmetics and oil extraction, such as as a thickener and fluid loss reducer in drilling fluids.
In addition, sodium carboxymethyl cellulose also has excellent film forming properties and colloidal protection. In the food and pharmaceutical sectors, it can form a protective film to help stabilize product structure and extend shelf life. For example, in lithium batteries, it acts as a binder to enhance the stability of the electrode material.
Finally, the thermal and chemical stability of sodium carboxymethyl cellulose enables it to maintain its performance in high temperatures and complex chemical environments, which further expands its application range.
In summary, sodium carboxymethyl cellulose has shown strong application potential and market value in food, medicine, daily chemical, industry and other fields by virtue of its versatility, environmental protection and safety.
