One of the most versatile cellulose derivatives in industrial use. ZHAOYUAN supplies CMC across multiple grades and viscosity ranges for demanding applications worldwide.
Sodium Carboxymethyl Cellulose (CMC), also known as cellulose gum, is a water-soluble anionic polymer derived from natural cellulose. It functions as a thickener, binder, stabilizer, and water-retention agent across a wide range of industries.
ZHAOYUAN supplies CMC in multiple grades — from food-grade to specialized industrial grades — with viscosity ranging from 100 to 8,000 cps to meet diverse application requirements. Custom grades and packaging are available on request.

CMC is a water-soluble polymer derived from cellulose, used as a thickener, binder, stabilizer, and water-retention agent. Depending on grade, it's applied in food and beverage products, paper coating, ceramics, detergents, textiles, construction materials, and oilfield drilling fluids.
Viscosity ranges from 100 to 8,000 cps (Brookfield, 1% solution) across the full grade lineup, with each application grade — food, paper, ceramic, detergent, textile, mosquito coil, construction, and oilfield — sitting within a narrower typical range suited to that use.
Yes — the food-grade CMC is produced to E466 specification, with purity of at least 99.5% (dry basis), maximum 10% moisture content, and pH 6.5–8.5 in a 1% solution, meeting standard food-additive requirements.
Oilfield-grade CMC (typical viscosity 500–4,000 cps) provides fluid loss control and viscosity modification for water-based drilling muds at a lower cost than PAC, making it a suitable alternative for less demanding drilling applications where PAC's higher performance isn't required.
Standard packaging is 25 kg kraft paper bags with an inner polyethylene liner, with 500 kg or 1,000 kg jumbo bags available for bulk orders. Shelf life is 2 years from the manufacture date when stored in a cool, dry, well-ventilated area away from moisture and direct sunlight.
Yes. Beyond the standard grade lineup, custom degree of substitution (DS) and viscosity are available for specialty applications such as battery electrode binders, pharmaceutical excipients, and personal care formulations. Contact us with your target viscosity, DS, and application details.
CMC pricing depends on grade (food vs. industrial), viscosity range, degree of substitution, purity level, order quantity, and packaging (standard bags vs. bulk jumbo bags), as well as destination and shipping terms. Contact us with your specific grade and quantity for a quote.
Yes — a certificate of analysis (COA) and material safety data sheet (MSDS) are available on request with every shipment, confirming the grade's viscosity, DS, purity, and other specifications against the order requirements.
ZHAOYUAN supplies CMC directly from China with export capability for bulk orders worldwide, and also delivers turnkey EPC engineering for cellulose ether production plants — giving customers both a chemical supply source and a manufacturing-side engineering partner.
