Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Derivation of PNECs
The PNECs for the different compartments are calculated either by application of an assessment factor (PNECfreshwater, PNECmarine water, PNECintermittent release and PNECstp) or by using theequilibrium assumption method (PNECsediment-freshwater, PNECsediment-marine-water and PNECsoil). PNECair and PNECoral are not considered as relevant. The utilized procedures are described in detail in the ECHA REACH Guidance of May 2008, Chapter R.10 ("Characterisation of dose [concentration]-response for environment").
Conclusion on classification
Regarding all available data of the acute and/or chronic toxicity tests on aquatic organisms and taking into account the provisions laid down in CLP Regulation 1272/2008 (GHS), the substance does not have to be classified regarding possible acute and chronic ecotoxicological effects.
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.
