Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 bismuth tris(2-ethylhexanoate) in water, a complete dissociation resulting in bismuth and 2-ethylhexanoate ions may be assumed under environmental conditions. Thus, the transport and distribution of bismuth tris(2-ethylhexanoate) in the environment is most accurately evaluated by separately assessing the fate of its constituents bismuth and 2-ethylhexanoate.
Regarding bismuth, median log Kp values of 3.84 L/kg dw and 5.66 L/kg dw were determined for sediment and suspended matter, respectively. A log Kp value of 2.83 L/kg soil was selected for soil-water partitioning. Bismuth has a low mobility under relevant environmental conditions.
A significant adsorption to solid phases is not expected for the readily biodegradable 2-ethylhexanoate anion.
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.
