Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Conclusion on classification
The following key information was used for the environmental classification:
Lowest E(L)C50 value 0.54 mg/L to Daphnia magna (Anai, 2011)
Not ready biodegradable in an OECD 301C test (Mizuguchi, 2010)
Highest BCF (of several constituents): 584 (Murakami, 2011)
GHS:
As the lowest EC50 value (to Daphnia magna) was ≤1 mg/L, the substance has to be classified in the Category Acute 1 with H400.
As the lowest EC50 value (to Daphnia magna) was ≤1 mg/L and the substance is not ready biodegradable and the substance has a BCF of ≥500, the substance has to be classified in the Category Chronic 1 with H410.
DSD:
As the lowest EC50 value (to Daphnia magna) was ≤1 mg/L, the substance is not ready biodegradable and the BCF>100, the substance has to be classified as N, R50/53.
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.
