Description

Carboxymethylcellulose Calcium is the calcium salt of carboxymethylcellulose, a modified cellulose ether. This compound is valued for its excellent thickening, stabilizing, and water-retention properties in non-aqueous or low-moisture systems. It serves as a key functional ingredient for formulators in the pharmaceutical, food, and nutraceutical industries seeking controlled-release and tablet disintegration functionalities.

Application

• Pharmaceutical Excipient: Primarily used as a disintegrant in tablet and capsule formulations to promote rapid breakdown and drug release.
• Food Industry: Functions as a stabilizer, thickener, and texturizing agent in various food products, particularly where calcium fortification is beneficial.
• Nutraceuticals & Dietary Supplements: Employed in vitamin and mineral supplement tablets for its binding and disintegration properties.
• Industrial Applications: Acts as a binder, thickener, or suspension agent in ceramics, detergents, and paper products.
• Cosmetics & Personal Care: Used as a viscosity modifier and emulsion stabilizer in creams, lotions, and pastes.

Quality Control

Our Carboxymethylcellulose Calcium is manufactured under strict quality management systems. It can be supplied in grades compliant with major pharmacopoeial standards, including USP-NF and Ph. Eur., as well as FCC for food applications. Every batch undergoes rigorous testing for identity, assay, viscosity, and microbiological purity. A comprehensive Certificate of Analysis (COA) is provided with each shipment to ensure traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent caking or degradation due to moisture absorption.
