Description

Sodium Carboxymethyl Cellulose CAS NO 9004-32-4 is a water-soluble, anionic cellulose ether derived from natural polymer cellulose. This versatile compound is prized for its exceptional thickening, stabilizing, binding, and water-retention properties, making it a critical functional additive across numerous industries. It is an indispensable ingredient for formulators and manufacturers seeking to control rheology, improve texture, and ensure product stability. Key sectors that rely on this polymer include food and beverage, pharmaceuticals, personal care, detergents, and various industrial applications.

Application

• Food & Beverage Industry: Used as a thickener, stabilizer, and texture modifier in ice cream, dairy products, sauces, baked goods, and beverages to prevent ingredient separation and improve mouthfeel.
• Pharmaceuticals: Serves as a binder and disintegrant in tablet formulations, a viscosity-increasing agent in liquid suspensions and ointments, and a stabilizer in various drug delivery systems.
• Personal Care & Cosmetics: Functions as a thickener, emulsion stabilizer, and film-forming agent in toothpastes, creams, lotions, shampoos, and other cosmetic products.
• Detergents & Household Cleaners: Acts as a soil-suspending agent, anti-redeposition agent, and viscosity builder in liquid and powder detergents to enhance cleaning performance.
• Paper & Textile Industry: Employed as a sizing agent, coating binder, and strength additive in paper manufacturing, and as a thickener in textile printing pastes and dyeing processes.
• Oilfield Drilling Fluids: A key component in water-based drilling muds to control fluid loss, lubricate the drill bit, and stabilize the borehole.
• Ceramics & Building Materials: Used as a water-retention aid and binder in ceramic glazes, tile adhesives, cement, and plaster to improve workability and adhesion.
• Other Industrial Uses: Finds application in adhesives, paints, coatings, and as a suspension aid in agrochemical formulations.

Quality Control

Our Sodium Carboxymethyl Cellulose is manufactured under a strict quality management system. We offer various grades, including Technical, Food (FCC), and Pharmaceutical (USP/EP) grades, each meeting stringent specifications for purity, viscosity, and degree of substitution. Every batch undergoes rigorous analytical testing to ensure consistency and performance. Certificates of Analysis (COA) are provided and available upon request to guarantee compliance with your specific application requirements.

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 product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent caking or lump formation due to absorption of atmospheric moisture. Keep away from strong acids and oxidizing agents.
