Magnesium chloride is the name for the chemical compounds with the formulas MgCl2 and its various hydrates MgCl2-(H2O)x. These salts are typical ionic halides, being highly soluble in water. The hydrated material can be extracted from brine or sea water. Magnesium chloride as the natural mineral Bischofite is also extracted (solution mining) out of ancient sea beds, for example the Zechstein seabed in NW Europe or the Permian Period seabed in the central parts of the US. Anhydrous MgCl2 is the principal precursor to magnesium metal, which is produced on a large scale.

Magnesium chloride (E511 is an important coagulant used in the preparation of cheese and tofu. In Japan it is sold as nigari (derived from the Japanese word for “bitter”), In China, it is called lushui. Nigari or lushui consists mostly of magnesium chloride, with some magnesium sulfate and other trace elements. It is also an ingredient in baby formula milk.

It is used for a variety of other applications besides the production of magnesium: the manufacture of textiles, paper, fireproofing agents, cements and refrigeration brine and dust and erosion control. Mixed with hydrated magnesium oxide, magnesium chloride forms a hard material called Sorel cement. Magnesium ion Mg2+ (usually added as the chloride) is an important component in the polymerase chain reaction, a procedure used to amplify DNA fragments. It is used in water treatment. It is also used as a humectant in paper industry.

It is also used in several medical and topical (skin related) applications. It has been used in pills as supplemental sources of magnesium, where it serves as a soluble compound which is not as laxative as magnesium sulfate, and more bio available than magnesium hydroxide and magnesium oxide, since it does not require stomach acid to produce soluble Mg2+ ion. It can also be used as an effective anesthetic for cephalopods and several species of bivalve, including oysters.

A number of state highway departments throughout the United States have decreased the use of rock salt and sand on roadways and have increased the use of solutions of magnesium chloride (often called “liquid magnesium chloride”) as a de-icer or anti-icer. It is much less toxic to plant life surrounding highways and airports, and is less corrosive to concrete and steel (and other iron alloys) than sodium chloride. Road departments and private industry may apply liquid or powdered magnesium chloride to control dust and erosion on unimproved (dirt or gravel) roads and dusty job sites such as quarries.

Magnesium chloride has shown promise as a storage material for hydrogen. Ammonia, which is rich in hydrogen atoms, is used as an intermediate storage material. Ammonia can be effectively adsorbed onto solid magnesium chloride, forming Mg(NH3)6Cl2. Ammonia is released by mild heat, and is then passed through a catalyst to give hydrogen gas.

Another major use is in the preparation of Oxychloride Cement (3MgO MgCl2-11H2 O) which are made up in carefully balanced proportions of MgCl2 and a dry mix consisting of calcined Magnesium Oxide (MgO) or Magnesite with fillers and other aggregates depending upon the requirement. It is used in industrial floorings, ship decks, railway passenger coach floorings, hospital floors and for aircraft hangar floors, ammunition factory floors, missile silos and underground armament factories and bunkers.

Magnesium chloride is used in the manufacturing of Abrasive Bricks for polishing of marble, granite and other stones which are becoming increasingly popular in the building industry today.

In the developing countries, as well as all other grain, pulses, and rice eating nations, Oxychloride Cement is used in the manufacture of soft grinding wheels ( Danish Stones).

It is also is used in the manufacture of Magnesium Hydroxide Mg(OH) 2 for further preparation of Antacids for relieving stomach problems and ulcers. It is also used for alimentation.

One of the most important uses of Magnesium Hydroxide today in Europe and America is as a flame retardant in polymers. It is used as a fire proofing agent for impregnation of wood, especially in mine timbers and specialized particle board. It is used in fire-extinguishing agents.

It is used directly extensively for sizing of cotton yarn, especially denim.

Extensively used for the treatment of Hypomagnesaemia (Grass Tetany or Grass Staggers). It is an additive in fertilizer industry. It is also used in sugar-beet processing and in processing Soya Bean as a food additive.

It is used in preparation of bath salts since it contains therapeutic minerals.
