Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Tris-(2-ethylhexyl)amine , which can be evaluated as having no long-term influence on nitrogen transformation in soils.
Key value for chemical safety assessment
- Long-term EC10 or NOEC for soil microorganisms:
- 1 000 mg/kg soil dw
Additional information
Experimental data on soil microorganisms are available for the substance.
In a study according to OECD 216 (soil microorganisms - nitrogen transformation test) the EC10 was determined to be 1000 mg/kg dw after 28 days; the EC25 and EC50 values were determined to be >1000mg/kg dw at the end of exposure. The nitrate amounts determined in the test assay without Luzerne meal on day 28 show a significant increase (compared with the same test assay of day 0).
Because the degree of inhibition at 1000 mg/kg Dw was less than 25 % at the end of the exposure, Tris-(2-ethylhexyl)amine can be evaluated as having no long-term influence on nitrogen transformation in soils.
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.
