Sodium Carboxymethyl Cellulose (CMC) is an anionic, water-soluble cellulose ether widely used as a thickener, stabilizer, water-retaining agent, and film-forming agent in various industries. With excellent dispersibility, rheology control, and compatibility, CMC improves product performance and processing efficiency across multiple applications.
CMC acts as a thickener, stabilizer, and emulsifier in beverages, ice cream, bakery, instant noodles, and sauces.
It improves texture, mouthfeel, and shelf life, ensuring consistent product quality.
Technical Data
Appearance: Free flowing white powder.
Viscosity: from low viscosity to 8000 cps (1% brookfield).
Purity: min 99.5%.
In water-based drilling fluids, CMC is used as a viscosifier and fluid loss reducer.
It enhances borehole stability, improves mud carrying capacity, and provides excellent salt resistance under various drilling conditions.

CMC acts as a selective depressant and dispersant in mineral separation. It helps improve ore grade and recovery rate, particularly in the flotation of hematite, lead-zinc, and phosphate ores.
In textile printing pastes, CMC provides good color yield, sharp pattern definition, and smooth flow properties. It replaces traditional natural thickeners, ensuring stable viscosity and easy washing after printing.
CMC is used as an anti-redeposition agent, preventing dirt from reattaching to fabrics during washing. It enhances detergency efficiency, especially in phosphate-free formulations.
