1, food grade

Uses: used as food additive, color stabilizer and pH regulator, as a supplement of magnesium in health care products and food. Used as decolorant and PH regulator of ice cream powder in sugar production. As an anti-caking agent and antacid, it can be used in wheat flour, milk powder chocolate, cocoa powder, grape powder, sugar powder and other fields. It can also be used to manufacture ceramics, enamels, glasses, dyes and other fields.

2. Medical level

Uses: Medical grade magnesium oxide can be used as antacid, adsorbent, desulfurizer, lead remover, complexing filter aid and PH regulator in biopharmaceutical field. It can be used as antacid and laxative in medicine to inhibit and relieve hyperacidity and treat gastric ulcer and duodenal ulcer. Neutralizing gastric acid is strong, slow and lasting, and does not produce carbon dioxide.

Extended data:

One of the main uses of magnesium oxide is as a flame retardant. In traditional flame retardant materials, halogen-containing polymers or halogen-containing flame retardants are widely used as flame retardant mixtures. However, in the event of a fire, due to thermal decomposition and combustion, a large amount of smoke and toxic corrosive gases will be produced, which will hinder fire fighting, personnel evacuation and corrosion of instruments and equipment.

Magnesium oxide stimulates mucous membrane to cause conjunctivitis and rhinitis. When people inhale magnesium oxide smog with the concentration of 4-6mg/m3 and 12 minutes, metal smog fever may occur, and patients may have symptoms such as fever, cough, oppression in the chest and obvious increase of white blood cells, but the symptoms caused by zinc oxide smog are mild and rare. It is reported that taking a large amount of magnesium oxide orally can cause fever and leukocytosis.
