CMC for Thickener CAS 9004-32-4

Sodium carboxymethyl cellulose (CMC-Na) is an organic compound with the chemical formula of [C6H7O2 (OH) 2OCH2COONa] n. It is a carboxymethyl derivative of cellulose and the most important ionic cellulose adhesive. Sodium carboxymethyl cellulose is usually an anionic polymer compound obtained by reacting natural cellulose with caustic soda and monochloroacetic acid, with a molecular weight ranging from several thousand to one million. CMC-Na is a white fibrous or granular powder that is odorless, odorless, and hygroscopic, and is easily dispersed in water to form a transparent colloidal solution. In the field of coatings, CMC can be used as a thickener, dispersant, leveling agent and wetting agent, etc., to help the coating better adhere to the surface and improve the smoothness and adhesion of the coating. In the field of paper and pulp, CMC can be used as a wet strength agent, adhesive, dispersant and anti-seepage agent to improve the strength and printing performance of paper. In the field of petroleum drilling fluid, CMC can be used as an important stabilizer and filter agent to help the drilling fluid maintain stability and filtration performance. In the food field, CMC can be used as a thickener, emulsifier and stabilizer to make yogurt, ice cream, jelly, condiments and bread and other foods.
