Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The PNECs for freshwater and marine aquatic organisms are based upon acute test results where no effects were observed at the highest limit test concentrations. Therefore they can be considered to be conservative and may overestimate the intrinsic toxicity of the substance.
Conclusion on classification
No acute toxicity was observed in fish, daphnia, and algae at concentrations greater than 100 mg/L. A NOEC from the algal study was also greater than 100 mg/L. Based upon these results the substance does not warrant classification for environmental 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.
