Description of key information

2-(2-aminoethoxy)ethanol (CAS 929-06-6) is acutely not harmful to algae.

Key value for chemical safety assessment

EC50 for freshwater algae:
202 mg/L
EC10 or NOEC for freshwater algae:
23.3 mg/L

Additional information

In a non-GLP, 72-hour static test with the green alga Scenedesmus subspicatus ( new name: Desmodesmus subspicatus) according to German Industrial Standard DIN 38412 part 9, the algae toxicity of 2-(2-aminoethoxy)ethanol was investigated. Statistical evaluation of the endpoint growth rate revealed an EC50 (72h) of 202 mg/L, the NOEC was estimated to be 62.5 mg/L. Moreover, a read-across analysis was performed with QSAR Toolbox v4.4. The 72 -h EC10 was determined to be 23.3 mg/L (BASF SE, 2021).

Overall, it can be concluded that 2-(2-aminoethoxy)ethanol (CAS 929-06-6) is with high probability acutely not harmful to algae.
