Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Based on the solubility of magnesium 2-ethylhexanoate in water (107.4 g/L at 20 °C), a complete dissociation of magnesium 2-ethylhexanoate may be assumed. Upon dissolution, magnesium and 2-ethylhexanoate ions therefore determine the environmental fate of magnesium 2-ethylhexanoate. Magnesium is highly mobile under all environmental conditions and occurs in solution as dissociated Mg2+ ions. A European median log Kp value of 2.96 is derived for sediment-water partitioning, and magnesium is expected to be highly mobile in suspended matter and soil. For 2-ethylhexanoate, significant adsorption to the solid soil phase is not expected based on available data collected according to OECD106 guideline. Therefore, magnesium 2-ethylhexanoate may be assumed to be mobile under environmental conditions.
Key value for chemical safety assessment
Additional information
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.
