Product Description
Sodium Carboxymethyl Cellulose (CMC-Na)
Sodium carboxymethyl cellulose (CMC-Na) is an organic substance with the chemical formula [C6H7O2(OH)2OCH2COONa]n, which is a carboxymethylated derivative of cellulose, and is the most important ionic cellulose gum. Sodium carboxymethyl cellulose is typically produced as an anionic polymer compound through the reaction of natural cellulose with caustic soda and monochloroacetic acid, with molecular weights ranging from several thousand to over one million.
CMC-Na appears as a white fibrous or granular powder, is odorless and tasteless, exhibits hygroscopic properties, and readily disperses in water to form transparent colloidal solutions.
Key Benefits
- Effective thickening agent
- Superior emulsifying properties
- Excellent binding capabilities
- Forms transparent colloidal solutions
Target Industries & Applications
Food industry, pharmaceuticals, cosmetics, detergents, paper making, textiles, ceramics, oil drilling, construction, and other industries requiring thickening, binding, emulsifying, stabilizing, and film-forming properties.
