- 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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
