Calcium carboxymethyl cellulose

Calcium carboxymethyl cellulose (CAS 9050-04-8) is a water-soluble cellulose derivative in which calcium counterions replace the sodium found in standard CMC grades. It functions as a rheology modifier, dispersant, and moisture-retention agent across food, pharmaceutical, and industrial manufacturing processes. In pharmaceutical tablet manufacturing, it acts as a disintegrant and binder, supporting controlled release profiles where sodium content must be minimized. Food processors use it to stabilize emulsions, control texture, and retain moisture in baked goods and dairy alternatives.

Construction product formulators incorporate it into tile adhesives and cement-based mortars to improve water retention and workability during application. In textile and paper processing, it functions as a sizing and coating agent, improving surface uniformity and reducing fiber dusting. Calcium carboxymethyl cellulose is supplied as a white to off-white powder in varying particle sizes and viscosity grades. Food-grade and pharmaceutical-grade specifications are available, with purity and substitution degree typically defined per batch documentation.

Technical grades are also offered for construction and industrial applications where tighter pharmaceutical controls are not required. This versatile chemical ensures consistent performance across diverse manufacturing environments and specialized product formulations. The material is handled according to standard safety protocols for cellulose derivatives. It remains a preferred choice for manufacturers seeking high-purity additives that meet rigorous industrial and regulatory requirements for stability and performance.
