Sodium Carboxymethyl Cellulose (CMC) is a premium, non-toxic, and tasteless white flocculent powder engineered for exceptional stability and water solubility. Widely recognized as a versatile anionic cellulose ether, it serves as a high-performance binder, thickener, and stabilizer across a broad spectrum of industrial applications. Its ability to form transparent colloidal solutions with precise viscosity control makes it an indispensable additive for optimizing product texture and structural integrity.
Designed to meet rigorous global standards, our CMC is available in multiple specialized grades, including Food, Detergent, Oil Drilling, Ceramics, Paint, and Textile grades. By meticulously controlling the degree of substitution (DS) and molecular weight, we provide a product that ensures superior water retention, prevents sedimentation, and enhances the shelf-life of formulations, offering manufacturers a reliable solution for complex rheology modification.

Frequently Asked Questions
CMC acts as a multifunctional additive providing thickening, water retention, and dispersion stability. It prevents oil and water stratification, reduces ice crystal size in frozen foods, and improves mouthfeel and lubrication.
The DS indicates how many hydroxyl groups in cellulose are replaced by carboxymethyl groups. A higher DS generally enhances water solubility and thickening capability, though the ideal DS varies depending on the specific application.
It is recommended to add the powder slowly into water under continuous high-speed agitation. Pre-mixing with dry ingredients like salt or sugar can also improve dispersion. Allow sufficient hydration time for full viscosity development.
CMC is widely used as a sizing agent in textiles and paper making, an excipient/plasticizer in ceramics, an anti-redeposition agent in detergents, and a fluid-loss stabilizer in oil drilling mud.
CMC is generally thermally stable, but viscosity tends to decrease as temperature increases. Prolonged heating above 80°C can cause colloid denaturation, leading to a significant reduction in viscosity and performance.
Yes, Food Grade CMC is non-toxic, tasteless, and odorless. It is recognized as safe and reliable, and its dosage is generally not restricted by food hygiene standards (ADI).
