Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Short-term toxicity tests are available for all three trophic levels (fish, invertebrates and algae). The 96 -hour LC50 in zebra fish is 213 mg/L, the 48 -hour EC50 in Daphnia magna is 180 mg/L, and the 72 -hour ErC50 and ErC10 in algae are 100 mg/L and 2.3 mg/L, respectively. In an activated sludge respiration inhibition test a 3-hour IC50 value of >320 mg/L was observed. Testing indicates that the test substance is not rapidly degradable (biotic and/or abiotic).
Conclusion on classification
Based on all available data for fish, aquatic invertebrates and algae, the test substance needs not to be classified according to Directive 67/548/EEC - Classification, Packaging and Labelling of Dangerous Substances or according to Regulation (EC) No. 1272/2008 on Classification, Labelling and Packaging of Substances and Mixtures (CLP))
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.
