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.

Where is Calcium carboxymethyl cellulose used?

• Pharmaceutical tablets: disintegrant and binder supporting controlled release where sodium content must be minimized
• Food: stabilizer of emulsions, texture control and moisture retention in baked goods and dairy alternatives
• Construction: water retention and workability in tile adhesives and cement-based mortars
• Textile and paper: sizing and coating agent improving surface uniformity and reducing fiber dusting
• It functions as a rheology modifier, dispersant, and moisture-retention agent.

Commercial specifications

• White to off-white powder in varying particle sizes and viscosity grades
• Food-grade and pharmaceutical-grade specifications; purity and substitution degree defined per batch documentation
