Details on results:
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. Information is provided on the main hydrolysis product of (2-ethylhexanoato-O)oxoaluminium, namely ethylhexanoic acid.

Applicant's summary and conclusion

Conclusions:
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. Information is provided on the main hydrolysis product of (2-ethylhexanoato-O)oxoaluminium, namely ethylhexanoic acid.
The main hydrolysis product, 2-ethylhexanoic acid, has a log Kow of 2.64.
