Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Acute toxicity to fish has been investigated in a semi-static test in accordance with OECD/EU test methods. Groups of 10 fish were exposed to concentrations of 50, 100 or 220 mg/L for a period of 96 hours. The median lethal concentration was >50 <100 mg/L. The LOEC, based on behavioural effects, was 50 mg/L.
Acute toxicity to Daphnia magna has been investigated in a static test at a limit concentration 100 mg/L in accordance with OECD/EU test methods. No effects occurred during the 48 hour exposure period and the NOEC was 100 mg/L.
Toxicity to freshwater green algae has been investigated in accordance with OECD/EU test methods. Effects on growth rate and yield over a period of 72 hours were assessed at a limit concentration of 100 mg/L. No inhibition of growth occurred over a 72 hour exposure period and the NOEC was 100 mg/L. In accordance with ECHA guidance on information requirements and chemical safety assessment, Chapter R.7b: Endpoint specific guidance, theErC50 endpoint is used in DNEL derivation. This is because use of values based on biomass cannot be applied to an analysis of results from a system in exponential growth without logarithmic transformation.
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.
