Description of key information

The 21d-NOEC to Daphnia magna of the structurally related substance Ethylenediamine, ethoxylated and propoxylated (CAS 25214-63-5) in a OECD 211 guideline study is = 10 mg/l (nominal) for all endpoints.

Key value for chemical safety assessment

Additional information

Chronic toxicity to invertebrates has been investigated in a reproduction test with Daphnia magna following the OECD guideline 211 using semi-static exposure. No effects were observed at the maximum concentration tested (10 mg/l) and the NOEC are reported = 10 mg/l (nominal) for reproduction and mortality. Exposure concentrations were verified by mean of HPLC-MSD and were ranging between 98.3 and 118.4% of the nominal concentrations.
