Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Daphnia magna were exposed for 48 hours under flow-through conditions to five mean measured concentrations of the substance ranging from 0.39 to 8.7 mg/L in a study performed according to OECD TG 202 [Brougher et al, 2014]. The 48-hour EC50 value was 2.8 mg/L, with a 95% confidence interval of 2.2 to 3.6 mg/L. The slope of the concentration-response curve was 3.5. The no-immobility concentration and the NOEC were 0.84 mg/L.
This result is supported by the results of a study performed according to EPA OTS 797.1300 using a read-across substance, N,N-dimethyldecan-1 -amide, mixture with N,N-dimethyloctan-1 -amide (CAS No. 67359 -57 -3) in which daphnia magna were exposed to the substance for 48 hours under static conditions [Forbis, 1990]. The 48 -hour LC50 was 7.7 mg/L and the NOEC was 4.0 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.
