Description

Magnesium Chloride is an essential inorganic salt widely recognized for its versatile chemical and physical properties. It is a critical raw material valued for its role in industrial processes, nutritional supplementation, and environmental management. This compound is indispensable for manufacturers and processors in sectors such as chemical synthesis, food technology, agriculture, and water treatment, where consistent quality and reliable supply are paramount.

Application

• Chemical Manufacturing: As a precursor for producing magnesium metal, magnesium oxide (magnesia), and various other magnesium compounds.
• Food Industry: Used as a firming agent, flavor enhancer, and a source of dietary magnesium in food-grade and FCC-grade products.
• Dust Control & De-icing: Applied on unpaved roads and surfaces for effective dust suppression and as a less corrosive alternative to traditional road salts for ice melting.
• Water Treatment: Acts as a coagulation aid and a magnesium source in wastewater treatment and desalination processes.
• Agriculture & Animal Feed: Serves as a magnesium nutrient in fertilizers to correct soil deficiencies and as a feed supplement for livestock.
• Pharmaceuticals: Utilized in the production of medicinal preparations and as an electrolyte replenisher, meeting stringent pharmacopeial standards (USP/EP).
• Textile & Paper: Employed in fabric finishing and as a component in paper manufacturing processes.
• Construction: Used in the formulation of magnesium oxychloride (Sorel) cement and other specialty building materials.

Quality Control

Our Magnesium Chloride is produced under a strict quality management system to ensure batch-to-batch consistency and compliance with international standards. We offer various grades, including Industrial, Food (FCC), and Pharmaceutical (USP/EP), each with tailored specifications. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing parameters such as assay, heavy metal content, and loss on drying to guarantee product integrity for your specific application.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture and caking.
