Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
LC50 for freshwater fish-96h is above 9.9 mg/L. (the highest and nominal concentration is 100mg/L, the water solubility is <0.3mg/L)
Key value for chemical safety assessment

Additional information
The LC50 was based on the measured concentrations at 96 hours. The test substance was dispersed in water at levels above its water solubility, with nominal concentrations up to 100mg/L being used. Homogenous solutions are claimed for all concentrations, with turbidity observed at the higher levels. Actual measured concentrations were lower than nominal, and declined during the test due to some settleing. No mortalities or other effects were observed at any concentration.
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.
