Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Short-term toxicity to fish
Administrative data

Description of key information
With high probability acutely not harmful to fish. No acute toxic effects occur within the range of solubility.
Key value for chemical safety assessment
Additional information
The acute toxicity to fish was tested in a GLP guideline study according to OECD 203 (CIBA-GEIGY 1993e) using zebrafish. Due to the low solubility of the test substance a supersaturated stock solution using an emulsifier (alkylphenol-polyglycolether) has been prepared. Calculated amounts of the stock solution to produce the desired test concentrations (nominal: 10, 18, 32, 58 and 100 mg/L) were given into the water and were homogeneously distributed. A deposit of test substance was observed at all test concentrations at the end of exposure. However, no acute toxic effects have been observed within the range of solubility in any of the tested concentrations. Therefore, the LC50 after 96 h is above 100 mg/L (nominal) and 9.2 mg/L (measured at the end of the test), respectively.
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.
