Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A static test was performed according to the OECD Guideline 202 (2004) and the EU method C.2 of the Regulation (EC) No. 440/2008. 5 concentrations were used ranging from 4.6 to 100 mg/L (nominal concentration). For each test concentration and the blank control, 20 Daphnia were exposed to the test item for 48 hours. After 24 and 48 hours, the immobilised Daphnia were counted.
The measured concentrations lay between 89 % and 97 % of the nominal concentrations at the beginning of the test and between 97 % and 107 % of the nominal concentrations at the end of the test.
Therefore, the determination of the biological results was based on the nominal 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.
