• Description: Magnesium carbonate (MgCO3, pKso=7.5-8.2), another important compound of magnesium, occurs naturally as magnesite,but the magnesium carbonate used in the United States is all synthetically manufactured. It's used in the pharmaceutical industry as an inert material: whenever you take a tablet, chances are, you're also taking magnesium carbonate. Its used as an inert binder to hold the actual particles of the drug together.It's also used in cosmetics, talcum powders, and the manufacture of soap because it can hold and carry a scent very effectively. Magnesium carbonate is added to rubber and plastics as a flame retardant: it reduces the rate at which fire spreads and the amount of char and ash that is produced. Magnesium carbonate is obtained mainly by mining the natural mineral magnesite. The trihydrate salt, MgCO3·3H2O, is prepared by mixing solutions of magnesium and carbonate ions in the presence of carbon dioxide.
• Physical properties: This material is available in a very light, fluffy grade which absorbs well. The before-mentioned qualities are why magnesium carbonate is often used to absorb perfume before incorporation into face powders.
• Uses: Chemical intermediate for magnesium salts; component of pharmaceuticals, cosmetics, dentifrices, free-running table salt; agent in heat insulation and refractory applications Some applications of magnesiumcarbonate are uses in flooring, fireproofing and fire-extinguishing compositions; as a filler material and smoke suppressant in plastics; as a reinforcing agent in neoprene rubber; as a drying agent and for color retention in foods; in cosmetics. Magnesium carbonate is used as an antacid in medicine and as an additive to table salt. Another important application of magnesium carbonate is as a starting material in producing a number of magnesium compounds. Because of its water-insoluble, hygroscopic properties, MgCO3 was first added to salt in 1911 to make the salt flow more freely. Magnesium carbonate, most often referred to as “chalk”, is used as a drying agent for hands in gymnastics, weight lifting and rock climbing. Magnesium carbonate is also used in taxidermy for whitening skulls. It can be mixed with hydrogen peroxide to create a paste, which is then spread on the skull to give it awhite finish. Basic magnesium carbonate is used as a clay in face masks and it has mild astringent properties and helps to smooth and soften skin. It is recommended for use on normal to dry skins. Used in Pharmaceutical units as a Magnesium Salt, Heat Insulator and Refractor, Antacid. Also used in Cosmetics, inks, glass, drying agent, color retention agent and etc.
