Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Data for other trophic levels are available: Algae (EC50 = 0.652 mg/L; NOEC = 0.063 mg/L) and daphnia (EC50 = 19.4 mg/L; NOEC = 10.4 mg/L). From the ratio NOEC/EC50 for algae (0.063/0.652 = 0.097) and the lowest available LC50 for fish (72 mg/L) a NOEC of about 7.0 mg/L can be extrapolated. This is higher than already available NOEC data for algae and is therefore considered as not relevant for further assessment.
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.
