Magnesium chromate is a chemical compound, with the formulaMgCrO4. It is a yellow, odorless, water-soluble salt with several important industrial uses. This chromate can be manufactured as a powder.
Before 1940, the literature about magnesium chromate and its hydrates was sparse, but studies starting in that year looked at its properties and solubility.[1]
As a hydrate, it is useful as a corrosion inhibitor and pigment,[4] or as an ingredient incosmetics.[5][dubious –discuss]In 2011, an undecahydrate (containing 11 molecules of water) of this compound was discovered by scientists at theUniversity College London.[6]
Magnesium chromate hydrate should be stored atroom temperature, and there is no current therapeutic use.[7] It is a confirmedcarcinogen, and can cause acutedermatitis, and possibly kidney and liver damage if inhaled, so it should be treated as ahazardous waste.[8]
