Is magnesium oxide toxic

Toxic. If taken by mistake, it will cause diarrhea and dehydration.


1. magnesium oxide stimulates mucous membrane to cause conjunctivitis and rhinitis. When people inhale magnesium oxide dust with a concentration of 4-6mg/m3 for 1 to 2 minutes, they may have metal smoke heat, fever, cough, chest compression, and obvious increase of white blood cells.


2. eating by mistake is harmful and may cause allergy. Avoid inhaling gas or dust. Use in well ventilated places. Avoid contact with eyes, skin or clothing. Please clean thoroughly after use and ensure that the container is closed.

6. magnesium oxide has high fire resistance and insulation performance. It can be transformed into crystal after high temperature burning above 1000 ℃, and it will become dead burned magnesium oxide or sintered magnesium oxide when it rises to 1500 - 2000 ° C.
