Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Diss Factsheets

Administrative data

water solubility
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is hydrolytically unstable at pH 4, 7 and 9 (half-life less than 12 hours)
Justification for type of information:
The substance is a UVCB reactive aluminium complex, that is expected to hydrolyse quickly on contact with water or moisture. The substance is not amenable to experimental or calculated determination of the octanol-water partition.
Substance is expected to undergo fast hydrolysis, as with other such oxoaluminium complexes that are manufactured and used in the same way.
The hydrolysis products are: aluminium hydroxide oxide (CAS 24623-77-6) [mixture of aluminium hydroxide (CAS 1344-28-1) and aluminium oxide (CAS 21645-51-2)], and 2-ethylhexanoic acid (CAS 149-57-5) with reported water solubility of 1.4 g/L at 20 °C, pH 3.3 (ie for non-ionised form).
