Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Based on short-term study for aquatic organisms results representing all three trophic levels, the EC50 (48h) for daphnid of 22 mg/L is taken for the assessment. The EPM is used for determining sediment PNECs.
PNEC stp should read >2.8 mg/L.
Conclusion on classification
There is limited potential for bioaccumulation of the substance. There was no biodegradation observed in a ready biodegradation study. Short-term studies are available for fish, daphnid, and alga for the purpose of classification, where LC50 and EC50 results are above 10 mg/L.
According to EU classification criteria, the substance is classified as R52/53 under Directive 67/548/EEC and Aquatic Chronic Category 3 under CLP Regulation (EC) No 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
