Sodium Carboxymethyl Cellulose (CMC) – High-Viscosity Binder

Sodium Carboxymethyl Cellulose (CMC) is a cellulose derivative created through the chemical modification of natural cellulose. It functions as an effective rheology modifier, water retention aid, and emulsion stabilizer. Known for its high solubility in cold and hot water, CMC delivers consistent performance in a wide range of industries including food processing, oil and gas, ceramics, construction, paints, detergents, and paper manufacturing.

Cavin Resource offers industrial, food-grade, and technical-grade CMC in bulk quantities, manufactured under strict quality standards. We ship globally and cater to the custom formulation needs of manufacturers and wholesale buyers.

⚙️ Production Method

1. Alkalization

• Cellulose is treated with sodium hydroxide (NaOH) to produce alkali cellulose.

2. Etherification

• Alkali cellulose reacts with monochloroacetic acid to form sodium carboxymethyl cellulose.

3. Purification & Drying

• Product is neutralized, filtered, dried, and milled into a fine white powder.

🏭 Applications & Industry Use Cases

🥣 Food & Beverage Industry

• Acts as a thickener, stabilizer, and fat replacer in products like sauces, ice cream, yogurt, and bakery fillings.

💊 Pharmaceuticals

• Used as a tablet binder and controlled-release agent in drugs and syrups.

🧪 Oil Drilling & Mining

• Serves as a viscosity modifier and fluid loss reducer in drilling fluids and fracturing operations.

🏗️ Construction & Ceramics

• Enhances plasticity, water retention, and adhesion in tile adhesives, mortars, and ceramic slurries.

🧼 Detergents & Cosmetics

• Used to suspend solids, improve texture, and prevent ingredient separation in liquid formulations.
