Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Expert Judgement
Phototransformation in air is not expected to be an important environmental fate process since this compound lacks functional groups that is susceptible under environmental conditions, magnesium massive as an inorganic compound cannot broken down by photons.
Magnesium do not contain chromophores that absorb at wavelengths >290 nm and therefore Magnesium massive is not expected to be susceptible to direct photolysis by sunlight.
Magnesium does not react with dry air but slowly gets tarnished in most air due to the formation of a thin film of the oxide.
Therefore testing for Phototransformation in air does not need to be performed.
