Description of key information

One chronic earthworm test has been performed according to OECD 222 with tallow based diamine ethoxylate (CAS No 90367-27-4) resulting in a NOEC of 500 mg/kg dw. Read across of this result to other diamine ethoxylates is considered justified as these substances are part of the same category, have a similar carbon chain distribution.

Key value for chemical safety assessment

Long-term EC10, LC10 or NOEC for soil macroorganisms:
500 mg/kg soil dw

Additional information

No effects observed in a chronic terrestrial test up to 500 mg/kg dw. However, at 1000 mg/kg soil dry weight the reproduction of the adult earthworms was statistically significantly reduced compared to the control.
