Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Abiotic degradation is specifically needed for organic substances and less relevant for inorganic substances. It can be reasonably assumed that in the aquatic environment the test substance will normally be completely dissociated into its ions.

This conclusion can be based on the justifications of the three main components:

Hydrolysis changes the chemical form but does not decompose aluminium and characterization of total aluminium considers all chemical forms. Thus, the concept of degradation of aluminium by hydrolysis is not relevant in the consideration of its environmental fate.

The ions of calcium oxide will react with HCO3- to form water and carbonate ions which react with Ca2+ to form calcium carbonate. Calcium carbonate precipitates and deposits on the sediment. Calcium carbonate is a constituent of natural soils. Depending on the properties of the test medium, calcium oxide will be strongly neutralised in the initial period after application.

Magnesium oxide (MgO) is exempted from registration according to EC 1907/2006 Annex V Section 10.
