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.
