Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A Daphnia magna (Crustacea, Cladocera) reproduction test was performed according to the OECD Guideline No 211 (adopted September 21, 1998) and Principles of Good Laboratory Practice (GLP, OECD 1997).
The aim of the study was the determination of the reproductive output of Daphnia magna exposed to a range of concentrations of the test substance (determination of NOEC after 21-day exposure).
Due to the low water solubility the test item was tested as “water accommodated fractions” (WAFs) at 5 nominal concentrations between 6.25 mg/L and 100 mg/L.
Concerning the mean cumulative offspring per survivor the results are:
EL50 (Effective Loading rate) is > 100 mg/L
LOELR (Lowest Effective Loading Rate)> 100 mg/L
NOELR (No Observed Effect Loading Rate) ≥ 100 mg/L
Key value for chemical safety assessment
Additional information
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.
