Professional manufacturer and supplier of Carboxymethyl Cellulose (CMC) and Polyanionic Cellulose (PAC). Delivering consistent quality, customized specifications, and reliable supply to clients worldwide.
Ever Bright Group is a global leader in slurry-method sodium carboxymethyl cellulose (CMC) and polyanionic cellulose (PAC) production. With 60,000 tons annual capacity across our Shanghai and Yantai bases, we deliver food-grade, battery-grade, pharmaceutical-grade, toothpaste-grade, and industrial-grade products with precise control over purity, substitution degree, viscosity, pH, and moisture content.
"EVER BRIGHT" Sodium Carboxymethyl Cellulose (CMC) is produced using high-quality imported raw materials and China's most advanced slurry-method manufacturing process. Known as "industrial MSG," CMC is a water-soluble anionic polymer that functions as a thickener, stabilizer, binder, and water-retention agent.
With a complete range of models and viscosities, our CMC offers excellent performance, stable quality, uniform substitution, and strong resistance to acid, salt, and heat. Available in food-grade, battery-grade, pharmaceutical-grade, toothpaste-grade, and industrial-grade — all as white high-purity powder. We customize every specification to your application, with batch-to-batch consistency verified by our ISO 22000-certified quality system.

Polyanionic Cellulose (PAC) is a high-purity, high-substitution derivative of carboxymethyl cellulose. With its higher degree of substitution and purity, PAC offers superior solubility, salt tolerance, and thermal stability compared to standard CMC.
PAC is widely recognized as a premium filtration control agent and viscosifier in oil and gas drilling fluids, where performance under extreme conditions is critical.
| Purity | ≥ 99.0% |
|---|---|
| Degree of Substitution (DS) | 0.80 – 2.00 |
| Viscosity (2% solution, 25°C) | 100 – 10000 mPa·s |
| pH Value (1% solution) | 6.0 – 8.5 |
| Moisture Content | ≤ 8% |
Our CMC and PAC products are engineered to perform across 12+ industries — from food and beverage to oilfield drilling, lithium batteries, pharmaceuticals, and beyond. Known as "industrial MSG," CMC delivers thickening, stabilizing, binding, and water-retention performance tailored to each application.
Thickener, stabilizer, and emulsifier in yogurt, juice, protein drinks, cheese, sauces, bakery, ice cream, and condiments. Prevents protein precipitation, suspends fruit particles, enhances texture, and extends shelf life. Complies with GB2760, FDA 21 CFR 182.1745, JECFA, and USP standards.
Premium filtration control agent and viscosifier in water-based drilling fluids. API-certified PAC grades (PAC-R, PAC-LV, PAC-HV) deliver excellent salt tolerance and thermal stability up to 150°C for high-temperature, high-pressure drilling environments.
Binder and thickener in lithium-ion, sodium-ion, and energy storage battery electrode manufacturing. Ultra-low iron and heavy metal content prevents short circuits and self-discharge, improves coating uniformity, electrode adhesion, and cycle life.
Binder and plasticizer in ceramic body and glaze formulations. Suspends glaze particles to prevent sedimentation, enhances green strength, reduces cracking during firing, and improves glaze uniformity and adhesion for tiles, tableware, and sanitary ware.
Surface sizing agent and coating binder in paper manufacturing. Improves paper surface strength, smoothness, printability, and ink absorption. Enhances coating uniformity and reduces dusting for fine paper, specialty paper, and paperboard.
Essential thickener and binder in toothpaste formulations — toothpaste cannot form without CMC. Provides smooth, glossy texture, controls hardness and consistency, prevents cracking, water separation, and layering, and ensures stable suspension of abrasives with excellent flavor release.
Rheology modifier, thickener, and stabilizer in water-based paints, coatings, putty, and mortar. Controls sagging and sedimentation, improves pigment dispersion, enhances water retention and crack resistance, and provides smooth application with excellent bonding performance.
Pharmaceutical-grade CMC used as tablet binder, disintegrant, suspending agent, and controlled-release matrix in tablets, capsules, ointments, and suspensions. High purity with strict heavy metal limits ensures safety and stability in pharmaceutical formulations.
Sizing agent and printing thickener in textile dyeing and printing. High-DS CMC increases yarn strength and abrasion resistance during weaving; as printing paste thickener, it provides sharp pattern definition, uniform color yield, and easy wash-off. Our white high-purity powder outperforms low-end yellow granular products.
Founded in 2002, Ever Bright Group operates Shanghai Ever Bright Enterprise Development Co., Ltd. and Shandong Yangtse Biotechnology Co., Ltd.
