Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 values are based on a GLP study performed according to OECD Guideline 201 (Alga, Growth Inhibition Test). Analytical support showed that the concentrations of the test item in test media remained within acceptable limits (>80% of nominal concentration). The growth rate inhibition effect concentrations for the inhibition of growth rate were ErC50 = > 100 mg/L, and ErC10 = 49.17 (95% confidence limits: 39.74 – 60.84) mg/L.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 100 mg/L
- EC10 or NOEC for freshwater algae:
- 49 mg/L
Additional information
Based on results of the statistical analysis, the NOEC and LOEC values for biomass (cell growth), growth rate and yield were 20.4 and 34.6 mg 2-(N-ethylanilino)ethanol/L, respectively.
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.
