Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

It is not possible to evaluate the toxicokinetics of trimethylaluminium as the substance reacts with water to produce aluminium hydroxide and methane or methanol and reacts spontaneously in air to form aluminium oxide, carbon dioxide and water. Therefore, the toxicokinetics effects of aluminium oxide and aluminium hydroxide need to be considered when evaluating the effects of exposure to trimethylaluminium.

Absorption of aluminium by the oral, inhalation and dermal routes is predicted to be low. Filtration in the kidneys is the main route by which systemic aluminium is excreted.
