Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The key value is based on an acute Immobilisation Study of 2-(N-ethylanilino)ethanol in Daphnia magna. It concerns a GLP study according to OECD Guideline 202 (Daphnia sp. Acute Immobilisation Test). Analytical support showed that the concentrations of 2-(N-ethylanilino)ethanol in test media remained within acceptable limits (>80% of nominal concentration). The EC50 (48 h) for 2-(N-ethylanilino)ethanol
was 22.16 mg /L with a 95% confidence interval of 18.32- 26.79 mg/L.
Key value for chemical safety assessment

- Effect concentration:
- 22 mg/L
Additional information
The highest tested concentration of the test item causing no immobilisation was 11.9 mg/L (No Observed Effect Concentration, NOEC) and the lowest tested concentration causing 100% immobilisation within the 48 h test period was 60.0 mg/L. The Lowest Observed Effect Concentration (LOEC) was 17.8 mg/L over the 48 h exposure period of the test item.
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).
