Understanding Carboxymethyl Cellulose Sodium

Carboxymethyl cellulose sodium (CMC-Na), a water-soluble polymer derived from cellulose, demonstrates exceptional binding and thickening properties. With a global market projected to reach $2.1 billion by 2028 (CAGR 5.7%), this multifunctional additive serves over 12 industries including pharmaceuticals, food processing, and petroleum extraction. Its molecular structure enables reversible gel formation at concentrations as low as 1.5% w/v, making it indispensable for viscosity control in aqueous systems.

Technical Advantages & Performance Metrics

Industrial-grade CMC-Na achieves viscosity ranges from 20 mPa·s to 15,000 mPa·s (1% solution, 25°C) through controlled substitution degrees (DS 0.4-1.2). Key parameters include:

• pH stability: 4-10 (optimal performance)
• Shear-thinning index (n): 0.3-0.7
• Moisture retention: 98.2% at RH 65%

Comparative testing shows 23% better film-forming capability than HPMC and 40% higher thermal stability versus standard cellulose ethers.
