Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Key value for chemical safety assessment
Additional information
The chemical safety assessment according to Annex I of Regulation (EC) No 1907/2006 indicates no need for further studies on terrestrial organisms. Thus in accordance with Regulation (EC) No. 1907/2006, Annex IX, Column 2, 9.4 further studies on the effects on terrestrial organisms do not have to be conducted. The substance is readily biodegradable and furthermore characterised by a low water solubility and high log Koc. Due to the expected environmental fate of the substance an exposure of terrestrial organisms is considered unlikely. The available long-term toxicity test on
Eisenia fetida demonstrated no detrimental effects on earthworms. The test was conducted n artificial soil according to OECD guideline 222 under GLP conditions. Nominal concentrations of 62.5, 125, 250, 500 and 1000 mg/kg dw were tested. The mortality and growth of adult earthworms was determined after 28 days. Another 28 days later the reproduction rate was assessed. Adverse effects of the substance were not observed and thus a NOEC (56 d) ≥ 1000 mg/kg was determined based on reproduction. Based on the available information toxicity of the substance to terrestrial organisms is not expected.
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.
