Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Administrative data
Link to relevant study record(s)
- Endpoint:
- toxicity to soil macroorganisms except arthropods: long-term
- Data waiving:
- exposure considerations
- Justification for data waiving:
- the study does not need to be conducted because direct and indirect exposure of the soil compartment is unlikely

Additional information
Taking the available information on exposure potential, biodegradability, adsorption potential and aquatic toxicity of the submission item into account, studies on the terrestrial toxicity of the substance are not indicated. The submission item is not supposed to be directly applied to soil and an indirect exposure to soil via sewage sludge transfer is unlikely since the substance is substantially biodegradable (pass level in a 301A study were reached, 10d-window is failed). For such a substance, it can be assumed that it will be biodegraded within the STP process and, as a consequence, the transfer to the soil compartment is not likely. Additionally, as the logKoc is below 3 and the substance has no cationic properties, a low adsorption potential is indicated. Therefore, binding to sewage sludge is unlikely and again, a transfer to the soil compartment is not expected. Furthermore, studies available on the aquatic toxicity of the submission item suggest a low hazard towards environmental organisms. Taking the available information into account, no studies on terrestrial organisms are deemed justified.
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.
