Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
With high probability acutely not toxic for fish.
Key value for chemical safety assessment
Additional information
2 -Morpholinoethanol was tested in a static limit acute toxicity test according to German Industrial Standard DIN 38412, Part 15 with Leuciscus idus. The 96 -h LC50 was > 500 mg/L (BASF AG 84/0420). The test concentration were not analytically verified, but are assumed to be stable over the test period due to the high water solubility (WS = >1000 g/L at 20 °C), the low vapour pressure (VP = 0.07 hPa at 20 °C), the low adsorption potential (log Koc (uncharged molecule; MCI-method) = 0.08; log Koc at pH 7 = 0.9) and the low Henry´s law constant (HLC (uncharged): 1.2E-6 Pa*m³/mol) of the chemical.
In an acute toxicity similar to OECD 203 under flow through conditions and with analytical verification of test item concentrations, the 96 -h LC50 was determined to be 2710 mg/L (Oncorhynchus mykiss; Geiger et al., 1985).
Based on these results it can be concluded with a high probability that 2 -morpholinoethanol is not acutely toxic for fish.
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.
