Description

Magnesium Carbonate CAS NO 13717-00-5 is a versatile inorganic salt widely used across multiple industries for its functional properties. Its primary value lies in its utility as an antacid, desiccant, filler, and processing aid, offering a combination of alkalinity, high surface area, and low density. This makes it an essential raw material for manufacturers in the pharmaceutical, food, personal care, and industrial sectors seeking reliable performance and compliance.

Application

• Pharmaceuticals: Used as an antacid in tablet and liquid formulations to neutralize stomach acid, and as a drying agent in capsule and powder manufacturing.
• Food & Beverage (FCC Grade): Acts as an anti-caking agent, acidity regulator, and drying agent in table salt, powdered foods, and dietary supplements.
• Personal Care & Cosmetics: Serves as an absorbent, opacifying agent, and viscosity modifier in body powders, face masks, and deodorants.
• Sports & Athletics: Applied as magnesium carbonate 'chalk' by gymnasts, weightlifters, and climbers to improve grip by absorbing moisture.
• Industrial Applications: Functions as a filler and reinforcing agent in rubber, plastics, and flooring materials, and as a flame retardant additive.
• Chemical Synthesis: Employed as a precursor in the production of other magnesium compounds and as a mild base in various chemical processes.

Quality Control

Our Magnesium Carbonate is produced under a stringent quality management system. We offer various grades, including Technical, Food (FCC), and Pharmaceutical (USP/EP) specifications, each subject to rigorous analytical testing. Key parameters such as assay, loss on ignition, heavy metals, and arsenic are strictly controlled. A Certificate of Analysis (COA) is provided with each batch to ensure traceability and compliance with your specific requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent absorption of moisture and carbon dioxide from the air.
