Description of key information

The result of a chronic earthworm test is available and no concern is indicated for the terrestrial compartment.

Key value for chemical safety assessment

Additional information

Alkyl amidoamines/imidazolines sorb strongly to soil but they hydrolyse quickly and the intermediates are biodegraded to CO2 and H2O and a polyethylene amine. The shortest poly amine DETA is also biodegraded. Therefore one chronic earthworm test has been performed to assess the long-term risk for terrestrial species. Further tests on terrestrial organisms do not need to be conducted if no concern is indicated for the terrestrial compartment based on one chronic test result.
