Description

Carboxymethyl Cellulose (CMC) is a versatile, water-soluble anionic polymer derived from cellulose. It serves as a critical functional additive, providing essential properties such as thickening, binding, film-forming, and moisture retention. This makes it indispensable across a wide range of industries, including food and beverage, pharmaceuticals, personal care, detergents, and paper manufacturing.

Application

• Food & Beverage: Used as a thickener, stabilizer, and texture modifier in ice cream, sauces, baked goods, and dairy products.
• Pharmaceuticals: Acts as a binder and disintegrant in tablet formulations, a viscosity modifier in liquid suspensions, and a protective colloid.
• Personal Care & Cosmetics: Functions as a thickener, emulsion stabilizer, and film-forming agent in toothpaste, creams, lotions, and shampoos.
• Detergents & Household Cleaners: Serves as a soil-suspending agent and anti-redeposition agent in laundry detergents.
• Paper Industry: Employed as a coating agent and strength additive to improve printability and paper quality.
• Oil & Gas Drilling: Used in drilling mud formulations as a viscosity control and fluid loss additive.
• Textiles: Acts as a sizing agent and thickener in printing pastes.
• Ceramics & Building Materials: Functions as a water retention aid and binder in tile adhesives and cement-based products.

Quality Control

Our Carboxymethyl Cellulose is manufactured under strict quality management systems. We offer various grades, including Technical, Food (FCC), and Pharmaceutical (USP/EP), each meeting stringent specifications for purity, viscosity, and degree of substitution. Every batch is accompanied by a comprehensive Certificate of Analysis (COA) to ensure traceability and compliance with your 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); the container must be kept tightly sealed to prevent caking and degradation from atmospheric moisture.
