Instead of choosing a product based only on cost, manufacturers should evaluate how its properties support their production goals. 

Understanding Natural magnesium chloride 

Natural magnesium chloride comes from mineral deposits or brine sources. After purification, it maintains its chemical properties for commercial use and provides a reliable magnesium chloride source. It is widely chosen for its versatility across multiple industries. 

Common characteristics include: 

  • Naturally sourced mineral compound 
  • Available in different purity grades 
  • Suitable for food, pharmaceutical, and industrial use after proper processing 
  • Excellent water solubility 
  • Good stability under recommended storage conditions 

Since the source material comes from nature, manufacturers should always choose suppliers that maintain strict quality control and testing procedures. 

What is Magnesium Chloride Hexahydrate? 

Magnesium chloride hexahydrate is a form of magnesium chloride with six water molecules in its crystal structure. This hydration affects its appearance, weight, handling, and performance. 

It is commonly supplied as magnesium chloride crystals, making storage, transportation, and controlled usage easier for many manufacturing environments. 

Typical properties include: 

  • Six water molecules chemically bound to each magnesium chloride molecule 
  • High water solubility 
  • Stable crystal structure 
  • Easy handling during industrial processing 
  • Suitable for applications requiring hydrated magnesium chloride 

Because hydration forms part of the chemical structure, manufacturers should consider this when calculating formulations.
