Description

Carboxymethylcellulose Sodium Salt is a water-soluble, anionic cellulose ether derived from natural polymer cellulose. It serves as a versatile and efficient thickener, binder, stabilizer, and water-retention agent across numerous industries. This high-purity product is essential for formulators and manufacturers requiring consistent rheological control and product performance. Key sectors that rely on its functionality include pharmaceuticals, food and beverage, personal care, and various industrial applications.

Application

• Pharmaceuticals: Used as a binder, disintegrant, and viscosity-modifying agent in tablet formulations, and as a suspending agent in liquid oral dosages.
• Food & Beverage: Functions as a thickener, stabilizer, and texture modifier in products like ice cream, dairy desserts, sauces, and baked goods to prevent syneresis.
• Personal Care & Cosmetics: Acts as a film-former, thickener, and emulsion stabilizer in toothpastes, creams, lotions, and shampoos.
• Industrial Applications: Employed as a water-retention agent and thickener in ceramic glazes, textile printing pastes, and paper coatings.
• Detergents & Cleaners: Serves as a soil-suspending agent and anti-redeposition agent in laundry detergents.
• Oil & Gas Drilling Fluids: Used as a viscosity modifier and fluid loss control additive in drilling muds.

Quality Control

Our Carboxymethylcellulose Sodium Salt is manufactured under strict quality management systems. It can be supplied in various grades, including Technical, Food (FCC), and Pharmaceutical (USP/EP) grades, to meet diverse application requirements. Each batch undergoes rigorous analytical testing to ensure compliance with specified parameters for viscosity, degree of substitution, purity, and moisture content. Certificates of Analysis (COA) are provided with every shipment to guarantee traceability and consistent quality.

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); the container must be kept tightly sealed after opening to prevent caking and degradation due to moisture absorption.
