Description

Carboxymethylcellulose Sodium is a water-soluble, anionic cellulose ether derived from natural polymer cellulose. This versatile compound is valued for its exceptional thickening, stabilizing, water-retention, and film-forming properties across numerous industries. It is a critical functional additive for formulators and manufacturers in sectors ranging from food and pharmaceuticals to personal care and industrial applications. Our supply of Carboxymethylcellulose Sodium CAS NO 12624-09-8 ensures consistent quality and reliable performance.

Application

• Food & Beverage: Acts as a thickener, stabilizer, and moisture-retention agent in ice cream, dairy products, baked goods, sauces, and beverages.
• Pharmaceuticals: Used as a binder, disintegrant, and sustained-release matrix in tablet formulations, and as a viscosity-enhancing agent in suspensions and topical gels.
• Personal Care & Cosmetics: Functions as a thickener, emulsion stabilizer, and film-former in toothpastes, creams, lotions, shampoos, and other cosmetic products.
• Industrial Applications: Serves as a key component in water-based paints, adhesives, ceramics, detergents, textile printing, and paper coating for viscosity control and improved performance.
• Oil & Gas Drilling Fluids: Employed as a fluid-loss control additive and viscosity modifier in drilling mud formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent caking or degradation due to moisture absorption.
