Description of key information

Key value for chemical safety assessment

EC50 for freshwater algae:
150 mg/L
EC10 or NOEC for freshwater algae:
52 mg/L

Additional information

The assessment of the toxicity of 2-aminoethyldiisopropylamine (CAS 121-05-1) to aquatic algae and cyanobacteria is based on a read-across approach to the structurally analogous substance ethyldiisopropylamine (CAS 7087-68-5).

 

A study on growth inhibition of the freshwater algae Pseudokirchneriella subcapitata, exposed to the analogue ethyldiisopropylamine (CAS 7087-68-5) for 72h, was performed according to OECD TG 201. The pH of the stock solution was adjusted to 8 in order to limit the pH increase during the test. Based on measured test concentrations the 72-h ErC50 was determined to be 150 mg/L (72-h ErC10 = 52 mg/L).

 

Based on the available read-across data, 2-aminoethyldiisopropylamine is assessed to be with high probability acutely not harmful to aquatic algae and cyanobacteria.
