Description of key information

No studies are available. A study is not required, because magnesium carbonate is a simple inorganic salt.

Key value for chemical safety assessment

Additional information

Magnesium carbonate is an inorganic substance and therefore does not undergo hydrolysis. In the environment, magnesium carbonate will dissociate into magnesium and carbonate ions. These ions are naturally ubiquitous in the environment; magnesium will be assimilated by species present in the water and is necessary to maintain a good chemical balance in soils, water and plants and carbonate will become part of the carbon cycle.

The performance of a hydrolysis study with magnesium carbonate is therefore scientifically unjustified.
