'''Magnesium peroxide''' is a fine powder [[peroxide]] with a white to white-off color. It is similar to [[calcium peroxide]] because magnesium peroxide also releases [[oxygen]] by breaking down at a controlled rate with a hydrous fluid. Besides this it can be used in bleaching, disinfecting, and deodorizing.
In contact with water it decomposes by the reactions:
: MgO<sub>2</sub>+ 2 H<sub>2</sub>O → Mg(OH)<sub>2</sub> + H<sub>2</sub>O<sub>2</sub>
: 2 H<sub>2</sub>O<sub>2</sub> → 2 H<sub>2</sub>O + O<sub>2</sub>
==Applications==
Magnesium peroxide being environmentally benign and its stable oxygen release are used widely in the [[Cosmetics|cosmetic]], [[agricultural]], [[pharmaceutical]], and [[natural environment|environmental]] industries. It is used to reduce contaminant levels in [[groundwater]]. Magnesium peroxide is used in the [[bioremediation]] of contaminated [[soil]] and can improve the soil quality for [[plant]] growth and [[metabolism]]. It also used in the [[aquaculture]] industry for bioremediation.
Commercially, magnesium peroxide exists as a form of compound of magnesium peroxide and [[magnesium hydroxide]].
