Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
Two short-term nominal toxicity test results for Zebra fish (Brachidanio rerio) are available. The highest tested concentration in both of the tests was 100 mg/l. No effects were seen at 100 mg/l. Other supporting information shows acute LC50 values for fish at the level of about 200-300 mg/l (dissolved).
Key value for chemical safety assessment
Fresh water fish
Fresh water fish
- Effect concentration:
- 100 mg/L
Additional information
In both tests the LC50 values were higher than 100 mg/l. A dose-response relation was not observed and, therefore, the highest tested concentration will be represented as a LC50 value in the PNEC derivation.
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).
