Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In the assessment of bismuth tris(2-ethylhexanoate), read-across to the assessment entities bismuth substances and 2-ethylhexanoic acid is applied since the ions of bismuth tris(2-ethylhexanoate) determine its fate and toxicity in the environment. A 3-h EC10 of 175.4 mg/L bismuth was determinedfor the respiration inhibition of activated sewage sludge whereas the NOEC amounts to≥ 300 mg/L (both nominal).The respective NOEC and EC10 values expressed as dissolved bismuth concentration (based on recovery of 4.7%) are ≥14.1 and 8.2 mg/L bismuth, respectively. Regarding 2-ethylhexanoate, EC10 (71.7 mg/L) and EC50 (112.1 mg/L) values were derived after 17 hours of exposure using Pseudomonas putida. Thus, bismuth tris(2-ethylhexanoate) has a moderate potential for toxicity to microorganisms.
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.
