Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Short-term toxicity to aquatic invertebrates

Description of key information
48-hour acute toxicity can be determined based on the results of the range finding and definitive phase of the Daphnia reproduction test
conducted.
The range finding test indicated that the 48h-EC50 was between 10 and 100 mg/L
The definitive test indicated that the 48h-EC50(immobility) was between 20 and 50 mg/L based on nominal concentrations
Based on linear interpolation the 48 h EC50 is ca. 35 mg/L based on nominal concentrations
Key value for chemical safety assessment
Fresh water invertebrates

- 35 mg/L
Additional information
Following the review of the Daphnia reproduction test (8237037) conducted with 2-(ethylamino)ethanol it can be concluded that the 48 hour EC50 for Daphnia magna was between nominal concentrations of 20 and 50 mg/L (using graphical interpolation this is approximatley 35 mg/L)
The overall mean measured concentrations of 2-(Ethylamino)ethanol in samples of test media were 0.585, 1.35, 3.11, 7.55, 21.0 and 49.1 mg/L, corresponding to 114, 105, 97.1, 94.4, 105 and 98.3% of the nominal concentrations, respectively. Results were therefore based on nominal concentrations.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
