Magnesium Oxide

Other names: Magnesium oxide, CI 77711, E530

Magnesium Oxide, also known as magnesium oxide, CI 77711 or E530, is an inorganic substance that in its pure form forms a white crystalline powder. It is a simple compound that is found in nature in the form of the mineral periclase. It is the result of a chemical reaction between magnesium and oxygen. It dissolves in water, but is not very soluble. Magnesium Oxide has a very wide range of uses. This is due to its properties such as high melting point and ability to resist corrosion.

Magnesium oxide finds its application mainly in medicine and food industry. In medicine, it is often used as a dietary supplement for people suffering from magnesium deficiency in the body. It is also used as a means of neutralising stomach acid and therefore as a remedy for heartburn. In the food industry, this oxide is used as an anti-caking additive, acidity regulator or stabilizer. As an additive, it is added to various products such as baked goods, cheese, ice cream and beverages under the designation E530. Its other use is in cosmetics, where it is added to various creams, powders and make-ups. It is also used in the manufacture of ceramics, glass, cement and some plastics. It is a material that is characterised by its versatility and wide range of uses.
