Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Endpoint:
- pyrophoric liquids
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is pyrophoric

Description of key information
The endpoint is waived: The substance is already classified as pyrophoric, water reactive liquid.
Key value for chemical safety assessment
- Flammability:
- spontaneously flammable in air (pyrophoric)
Additional information
According to the Annex VII Standard Information Requirements for REACH, determination of flammability is required. Column 2 - specific rules for adaption from column 1 - states that flammability determination does not need to be conducted in case the substance is pyrophoric. Aluminium alkyls are highly reactive both towards oxygen (air) and water as explained below. They are exclusively marketed in liquid state and shipped under UN transport class 4.2 (substances liable to spontaneous combustion / pyrophoric liquids) or at least under class 4.3 (substances which in contact with water emit flammable gases).
Justification for classification or non-classification
unpublished in-house testing and experience demonstrate that the substance is pyrophoric
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.
