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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No toxic effects have been observed in studies with soil living organisms.
Key value for chemical safety assessment
Additional information
Data on the test substance are not available. However, terrestrial studies on the toxicity to soil macroorganisms are available for two analogues substances (EC 465-080-5 and EC 401-540-3). For read-across justification see summary "Terrestrial toxicity".
In both GLP guideline studies according to OECD 207 Eisenia foetida have been exposed for 14 d with the respective test item (Bioassay and Safety Assessment Laboratory, APM 2013; CIBA-GEIGY 1990). No toxic effects have been observed up to the highest test concentration and the LC50 values after 14 d were determined to be > 1000 mg/kg soil dw for both analogue substances. Since the read-across is justified it can be concluded that also the test substance is with high probability not acutely toxic to soil macroorganisms.
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.
