Description

Calcium Carboxymethylcellulose CAS NO 9060-76-8 is the calcium salt of carboxymethylcellulose, a modified cellulose ether widely used as a stabilizer and viscosity modifier. This compound is valued for its ability to form stable colloidal dispersions and gels in aqueous systems, even in the presence of calcium ions. It is essential for industries requiring controlled rheology, suspension, and moisture retention in their formulations, particularly in pharmaceuticals, food products, and personal care.

Application

• Pharmaceutical Tableting: Acts as a binder and disintegrant in solid dosage forms, improving tablet integrity and dissolution.
• Food Stabilization: Used in dairy products, sauces, and dressings to prevent syneresis (water separation) and improve texture.
• Oral Care Products: Functions as a thickener and stabilizer in toothpaste and mouthwash formulations.
• Cosmetics & Personal Care: Serves as a suspending agent and viscosity enhancer in lotions, creams, and gels.
• Industrial Applications: Employed as a water-retention agent and thickener in ceramics, detergents, and paper coatings.
• Dietary Supplements: Used in capsule and tablet formulations as an excipient for its binding and flow properties.

Quality Control

Our Calcium Carboxymethylcellulose is manufactured under a strict quality management system. Each batch is tested to ensure it meets specifications for identity, purity, and performance. Certificates of Analysis (COA) are provided and the product can be supplied to meet various standards, including Food Chemical Codex (FCC) and pharmaceutical-grade requirements, upon request.

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 to prevent absorption of atmospheric moisture.
