Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Acute toxicity of the test substance to aquatic invertebrates was tested in a well-documented static freshwater Daphnia immobilization limit test conducted according to OECD Guideline 202. In the key study, daphnia were exposed to the test substance at measured concentrations between 4.6 - 104 mg/L for 48 hours.
The EC0 was determined to be >/= 104 mg/L (24-hr) and 8.4 mg/L (48-hr). The EC50 was observed to be > 104 mg/L (24-hr) and 102 mg/L (48-hr). The EC100 was > 104 mg/L (24-hr and 48-hr). The 48-hr NOEC was 49 mg/L.
The test results clearly demonstrate that the test substance is not acutely toxic to daphnia. Therefore, no further acute toxicity testing towards aquatic invertebrates was considered necessary.
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.
