Expert Verdict

Significant formulation hazard - MgH₂ is highly reactive with water, generating hydrogen gas (H₂) and magnesium hydroxide. This exothermic reaction means it must be carefully encapsulated or formulated in anhydrous systems. Risk of pressure buildup in sealed containers if water contact occurs. Not suitable for aqueous formulations without specialized delivery systems.. Releases molecular hydrogen (H₂), which is a selective antioxidant that scavenges hydroxyl radicals (·OH) without affecting b...
