Product Overview

Magnesium Chloride Hexahydrate FCC, USP Grade is a high-purity inorganic salt (MgCl₂·6H₂O) engineered to meet the rigorous standards of the Food Chemicals Codex (FCC) and United States Pharmacopeia (USP). Unlike technical grade alternatives, this product undergoes strict quality control to minimize heavy metals, halides, and other impurities, making it the preferred choice for regulated industries including food processing, pharmaceutical manufacturing, and precision chemical formulation.

With a typical assay of 99.5%, this hexahydrate salt exhibits excellent solubility and hygroscopic properties. It dissolves readily to form magnesium chloride solutions used in electrolyte replenishment, firming agents, and moisture management. While high enough in purity for consumable applications, it is also utilized in industrial settings requiring low-contaminant raw materials, such as specialty de-icing and dust control where environmental impact must be minimized.

Key Properties

  • CAS Number: 7791-18-6
  • Grade: FCC, USP (Food & Pharmaceutical Safe)
  • Assay (Wt %): 99.0% – 100.5% (Typical 99.5%)
  • Chemical Formula: MgCl₂·6H₂O
  • Appearance: White crystalline solid
  • Solubility: Highly soluble in water
  • Specific Gravity: 1.57 – 1.59
  • Chloride (Cl⁻): < 50 ppm
  • Heavy Metals: Strictly controlled per USP monographs

Common Applications

  • Food Processing: Used as a firming agent (to maintain crispness in canned vegetables) and color retention agent in food systems, complying with FCC purity standards.
  • Pharmaceutical Manufacturing: Functions as an excipient, hydration agent, or electrolyte source in various pharmaceutical formulations and dialysis solutions.
  • Chemical Synthesis: Acts as a high-purity source of magnesium ions for catalysts and chemical processing where trace contaminants found in technical grades would interfere with the reaction.
  • Dust Control & De-icing: High-performance ice melting and dust suppression for sensitive environments requiring non-toxic, low-corrosion profiles.
  • Water Treatment: Utilized in specific wastewater treatment processes for nutrient removal and pH adjustments.

Safety & Handling

Magnesium Chloride Hexahydrate is hygroscopic; store in tightly closed containers in a cool, dry area to prevent clumping and moisture absorption. Use High-Density Polyethylene (HDPE) or glass containers for long-term storage. While less hazardous than strong acids or bases, standard Personal Protective Equipment (PPE) including safety glasses, gloves, and long sleeves should be worn to prevent skin and eye irritation from dust or concentrated solutions.

Note: Incompatible with strong oxidizing agents. Ensure adequate ventilation during handling to minimize dust inhalation. Refer to the Safety Data Sheet (SDS) for detailed spill cleanup and emergency response procedures.
