Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 study was performed according to OECD guideline. The tested concentrations were 10, 18, 32, 58 and 100 mg/L (measured concentrations: 4.1, 7.0, 11.7, 22.2 and 39.1 mg/L respectively). The LC0 and LC100 are both higher than 100 mg/L. No mortality or visible abnormalities were observed during the test period of 96 hours. The LC50 (96h) was determined to be higher than 100 mg/L and the NOEC was found to be at least 100 mg/L.
The physical properties of the test substance do not allow to maintain the test substance homogeneously distributed in water. The highest test concentration (nominal 100 mg/L, analytically confirmed 39 mg/L at the end of exposure) produced no mortality to the test organism. It can therefore be assumed that the test substance cannot produce mortalities at concentrations below 100 mg/l.
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.
