Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Hydrolysis :
In aqueous solution, Magnesium Chloride is readily ionised (see conclusion on water solubility) to form Magnesium and Chloride ions which will combine to form other various inorganic complexes.
MgCl2+ H20 -> Mg2++ 2 Cl-
Therefore, hydrolysis is scientifically not relevant for MgCl2which will rapidly dissociate in water at environmentally relevant pH.
Biodegradation:
Magnesium Chloride is inorganic and can therefore not undergo any microbial degradation. The concept of degradability has non meaning for metal or metal compounds.
Bioaccumulation:
Magnesium Chloride dissociates into the Magnesium (Mg2+) and chloride (Cl-) ions at environmental pH. These are essential to all living organisms (flora and fauna) and their intracellular and extra-cellular concentrations are actively regulated. Hence, bioaccumulation is thus not expected.
Adsorption/Desorption:
Relating to the Kd values, Magnesium Chloride displays a moderate affinity for the solid phase of the sediment particles.
Additional information
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
