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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
The organic moiety sec-butanol, formed immediately when alumnium sec-butanolate comes in contact with moisture or water, is readily biodegradable, whereas the aluminium cation formed is ubiquitous in the environment thus not posing a risk.
As the risk assessment will be based on aluminium (III) species, no conclusion on degradation of this inorganic species can be drawn. It is assumed that the aluminium species remain in the water phase.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Testing of aluminium sec-butanolate for biodegradation is technically not feasible as the substance immediately dissociates to Al3+ species and 2-butanol upon contact with water or moisture. Sec-butanol is known to be readily biodegradable as demonstrated by the supportive study with a BOD5/COD ration > 0.5. Thus the organic moiety of the test substance is considered readily biodegradable.
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.
