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.
