Magnesium Chloride

Chemical Formula: MgCl2

HS Code: 28273100


Magnesium chloride is the name for the chemical compound with the formula MgCl2 and its various hydrates MgCl2(H2O)x. These salts are typical ionic halides, being highly soluble in water. The hydrated magnesium chloride can be extracted from brine or sea water. In North America, magnesium chloride is produced primarily from Great Salt Lake brine. It is extracted in a similar process from the Dead Sea in the Jordan Valley. Magnesium chloride, as the natural mineral bischofite, is also extracted (by solution mining) out of ancient seabeds, for example, the Zechstein seabed in northwest Europe. Some magnesium chloride is made from solar evaporation of seawater. Anhydrous magnesium chloride is the principal precursor to magnesium metal, which is produced on a large scale. Hydrated magnesium chloride is the form most readily available.

Magnesium chloride is used to form an ingredient used in foods. It forms a powder called tofu by mixing with soymilk. It is evidently important in the culinary sector. It is also added to formula milk fed to babies. It is a compound added to most foods sold to consumers and acts as a mineral supplement.


Plants need several minerals for growth. Magnesium chloride provides magnesium to plants to correct deficiencies in mineral content. Its use in farming is important since it is majorly used to replace magnesium sulfate. It is a preferred compound due to its high availability in the environment; this makes it reliable.


Magnesium chloride is an effective disinfectant used in treatment. It is now commonly used in preventing tissue damage despite its initial introduction as an antiseptic.  It is used as a solution to cleanse wounds on the skin.

Fire management

It has been used in the production of fire extinguishers. It is an important component in the making of gaseous extinguishers. Magnesium hydroxide reacts with hydrochloric acid to form a liquid used in extinguishers when combined with water. Companies that make fire extinguishers find this compound as critical to survival of their products.

Textile manufacturing

It is commonly used as a dye and as a compound in removal of waste in manufacturing industries. It does not only provide a cheap option but is also readily available for industrial use. It is used in printing mills to treat water and waste products.

Cement production

Magnesium chloride is used in the form of flakes in oxychloride cement. It is also available in pellets majorly used in winter due to easy distribution.
