Description

Cellulose, 6-Carboxy is a chemically modified cellulose derivative, also known as carboxymethyl cellulose (CMC), where carboxymethyl groups are introduced at the 6-position of the anhydroglucose units. This modification imparts excellent water solubility, thickening, and film-forming properties, making it a critical functional polymer for a wide range of industrial applications. It is essential for formulators and manufacturers seeking reliable rheology control, stabilization, and binding agents. Key industries that utilize this product include pharmaceuticals, food and beverage, personal care, and various industrial processes.

Application

• Pharmaceutical Formulations: Used as a binder, disintegrant, and viscosity-enhancing agent in tablet manufacturing, and as a stabilizer in suspensions and emulsions.
• Food & Beverage Industry: Functions as a thickener, stabilizer, and texture modifier in products like ice cream, sauces, dairy products, and gluten-free baked goods.
• Personal Care & Cosmetics: Serves as a thickener, emulsion stabilizer, and film-former in lotions, creams, toothpastes, and shampoos.
• Detergents & Household Cleaners: Acts as a soil-suspending agent and anti-redeposition agent in laundry detergents and cleaning formulations.
• Paper & Textile Manufacturing: Employed as a sizing agent, coating binder, and printing paste thickener to improve strength and finish.
• Oilfield Drilling Fluids: Used as a viscosifier and fluid loss control additive in water-based drilling muds.
• Ceramics & Adhesives: Functions as a binder and rheology modifier in ceramic glazes, tile adhesives, and construction materials.
• Industrial Coatings & Paints: Acts as a thickener and protective colloid to control application properties and stability.

Quality Control

Our Cellulose, 6-Carboxy is manufactured under a strict quality management system. Each batch undergoes rigorous testing to ensure it meets the required specifications for viscosity, degree of substitution, purity, and pH. We can supply grades compliant with relevant standards such as USP-NF, FCC, and Ph. Eur. where applicable. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and consistency for your production needs.

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