Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
If released into water, magnesium is not expected to adsorb to suspended solids and sediment based upon the estimated Koc value of 13.22 L/kg . Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant is 1.065E-037 atm-m3/mole.
Magnesium as an ingot is insoluble in pure cold water, but reacts with hot water to form Mg(OH)2 under the evolution of hydrogen gas. Reacts with seawater forming the chloride and sulphate.
On this basis phototransformation in water is not expected .
Therefore testing for Phototransformation in water does not need to be performed.

Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
