Sodium Carboxymethylcellulose (CMC)
CAS Number: 9004-32-4
Sodium carboxymethylcellulose (CMC) is a water-soluble cellulose ether produced by reacting cellulose with monochloroacetic acid. Food-grade CMC (E466) provides viscosity, water retention, and texture modification in ice cream, beverages, baked goods, and dairy products. Degree of substitution (DS) ranges from 0.6 to 0.9 for food applications, with viscosity grades spanning 50–50,000 mPa·s (1% solution).
