Description

6-Carboxycellulose, Calcium Salt is a modified cellulose derivative where carboxymethyl groups are partially neutralized with calcium ions. This compound is valued for its unique combination of cellulose's structural integrity with the ionic functionality of calcium carboxylate, offering specific rheological and binding properties. It finds significant utility in the pharmaceutical industry as a tablet disintegrant and binder, and in food technology as a stabilizer and thickener, particularly where calcium fortification is desired.

Application

• Pharmaceutical Excipient: Used as a binder and disintegrant in tablet formulations to control drug release and improve tablet integrity.
• Food Additive: Functions as a stabilizer, thickener, and calcium source in various food products, including dairy alternatives and fortified beverages.
• Cosmetics & Personal Care: Employed as a viscosity modifier and suspension agent in lotions, creams, and oral care products.
• Industrial Applications: Acts as a water-retention agent and binder in ceramics, construction materials, and paper coatings.
• Nutraceuticals: Serves as a carrier and excipient in dietary supplement tablets and capsules, providing a source of bioavailable calcium.
• Research & Development: Utilized in biochemical and material science research for studying ion-exchange polymers and biodegradable composites.

Quality Control

Our 6-Carboxycellulose, Calcium Salt 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) documenting key parameters such as assay, degree of substitution, viscosity, and heavy metal content are available upon request. We can supply grades compliant with relevant pharmacopeial (e.g., USP-NF, Ph. Eur.) or food (FCC) standards as required.

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) and must be kept in a low-humidity environment to prevent caking and degradation.
