 Magnesium hydroxide is best known as the active ingredient in Milk of Magnesia, an antacid and laxative which has been used for 150 years. It forms a suspension in water, and its reaction with acid only dissolves it gradually, giving it long-lasting effects. At higher doses, rather than acid neutralization, its primary action is to hold water, as it is not absorbed by the large intestine, relieving constipation.
It is also used as a fire retardant and smoke repressor in various applications due to an endothermic decomposition reaction which takes place at 332°C, releasing magnesia and water. Further applications include wastewater treatment, as a fuel additive, and production of magnesium salts.

Magnesium hydroxide is an excellent flame retardant for plastics and rubber products. In environmental protection, it is taken as flue gas desulfurization agent and can replace the caustic soda and lime as the neutralizer of acid-containing waste water and the absorbent of the heavy metal. In addition, it can also be used for the electronics industry, medicine, sugar refining, as insulation materials and for the manufacturing of other magnesium salt products.
Magnesium hydroxide is used as a flue gas desulfurization absorbent. In the 20th century, before the 1970s, most flue gas desulfurization applied sodium hydroxide method, limestone gypsum method. However, due to the secondary pollution of the byproducts to the environment, it has been switched to hydrogen magnesium oxide method since the 20th century; as acidic wastewater neutralizer; as the flame retardants of the synthetic resin; it was previously often used of bromine, phosphorus, chlorine and inorganic salt system. In these products, it had been mostly used of the aluminum hydroxide in these products. However, it has now been converted to magnesium hydroxide , mainly due to that in the thermoplastic resin, it can be increased of decomposition temperature to 350 ºC or more with magnesium hydroxide; it is medically used for the control of gastric acid and laxatives; food additives, as a mineral additive, color protection agent, desiccant, alkali agent and aid of sugar production; used as a chemical reagent for measuring ammonium salt: Mg (OH) 2 + 2NH4Cl → MgCl2 + 2NH4OH.
This product has a variety of advantage including being smoke-free, non-toxic, non-corrosive, cheap and easy to get advantages. Moreover, the temperature of its decomposition for release of water is higher than aluminum hydroxide, being more suitable for the requirement of high-temperature processing. Magnesium hydroxide can be used as the flame retardants of polyethylene, polypropylene, PVC, EPDM, unsaturated polyester and other plastics and rubber. It can also be used as the flame retardant of paint.
Magnesium hydroxide is an excellent flame retardant for plastics and rubber products. In environmental protection, it can be used as flue gas desulfurization agent, being able to replace the caustic soda and lime as acid-containing waste water neutralizer. It can also used as oil additive with anti-corrosion and desulfurization effect. In addition, it can also be used for the electronics industry, medicine, sugar refining, for insulation materials and the manufacture of other magnesium salt products.
One important application of Magnesium Hydroxide is the use of the material in the pharmaceutical industry, for example as antacid to neutralize stomach acids and as laxative.
The largest industrial application of Magnesium Hydroxide is flame retardants for articles such as roofing, isolation materials, plastic articles and coatings. The mechanism of flame retardancy is based on the endothermic decomposition of the material into MgO and H2O. This reaction adsorbs heat, which delays ignition of the associated substance. The water that is released dilutes combustible gases and inhibits oxygen from aiding the combustion.
