Sodium Carboxymethyl Cellulose (CMC / Na-CMC)
Thickening · Stabilizing · Water-Retaining Polysaccharide Powder
CAS No. 9004-32-4
White–Yellowish Powder
25kg Kraft Bag
Sodium Carboxymethyl Cellulose (CMC) is a water-soluble anionic linear polymer made from refined cotton pulp. It dissolves quickly in cold or hot water to form stable transparent colloid, offering reliable thickening, emulsification, suspension, film-forming and water retention performance. We supply customized CMC products with different viscosity and substitution degree to match diverse industrial demands.
Core Advantages
- Stable viscosity performance and good solution transparency
- Wide applicable pH range and acceptable salt resistance
- Excellent dispersibility and film forming property
- Low odor, safe formulation options available
- Custom specifications supported for your production
Detailed technical indicators, application categories and grade matching information are available in separate modules below. We provide full export service including product customization, formula consultation and supporting technical support.
