Is industrial magnesium oxide harmful to skin

It is harmful, but the harm is relatively small. The harm of industrial magnesium oxide is mainly manifested in that magnesium oxide is an alkaline substance that reacts with sweat or water on the skin surface, causing skin itching and dry skin peeling. Industrial magnesium oxide is generally highly active, so it is relatively easy to react with water on the skin surface. However, the relative solubility of magnesium hydroxide produced by the reaction is very small, and the alkaline phase of magnesium hydroxide is also very small It is very weak, so the harm to the body is not significant. Even the employees who have worked for many years in the posts with serious magnesium oxide dust have not found any obvious occupational disease.
