Description

Carboxymethylcellulose Sodium is a high-purity, water-soluble cellulose ether derived from natural polymer cellulose. This versatile compound is prized for its exceptional thickening, stabilizing, and water-retention properties, making it a critical functional additive across numerous industries. Key sectors that rely on this material include pharmaceuticals, food and beverage, personal care, and industrial manufacturing, where it serves as a binder, viscosity modifier, and film-forming agent.

Application

• Pharmaceuticals: Used as a binder, disintegrant, and viscosity-enhancing agent in tablet formulations, suspensions, and topical gels.
• Food & Beverage: Functions as a thickener, stabilizer, and texture modifier in products like ice cream, sauces, bakery fillings, and dairy alternatives.
• Personal Care & Cosmetics: Acts as a film-former, emulsion stabilizer, and viscosity controller in lotions, creams, toothpastes, and shampoos.
• Industrial Applications: Serves as a water-retention aid, thickener, and protective colloid in ceramics, detergents, paper coatings, and textile printing.
• Oil & Gas Drilling Fluids: Employed as a fluid loss control additive and viscosity regulator in drilling mud formulations.
• Paints & Adhesives: Used to control rheology, improve water retention, and stabilize pigment suspensions in water-based formulations.
