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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Key value for chemical safety assessment
- Vapour pressure:
- 1 Pa
- at the temperature of:
- 20 °C
Additional information
The vapour pressure of 2-ethylhexanoic acid, zirconium salt is considered to be negligible based on the fact that
(i) the vapour pressure of 2-ethylhexanoic acid is already low: 4 Pa at 20 °C (Flick, E.W. (ed.). Industrial Solvents Handbook 5th ed. Noyes Data Corporation, Westwood, New Jersey, USA, 1998, p. 664)
(ii) the vapour pressure of the 2-ethylhexanoic acid anion is considered to be magnitudes lower since the ionic bond strength is higher compared with the Van-der-Waals interaction of the uncharged molecule.
Thus, further testing is not required, according to Regulation (EC) No 1907/2006, Annex XI, Section 1.1.
The vapour pressure is set at 1 Pa as a worst case.
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.
