Description of key information

No chronic toxicity effect is expected for aquatic invertebrates since the water solubility (< 0.002 mg/L) is below any effect level (NOEC >= 10 mg/L).

Key value for chemical safety assessment

Additional information

For the assessment of the long-term toxicity of 2-ethyl-N,N-bis(2-ethylhexyl)hexylamine (CAS 1860-26-0) to aquatic invertebrates experimental data are available.

In the GLP key study conducted according to OECD Guideline 211 no ecotoxicity effect was observed (21-d NOEC >= 10 mg/L, nominal, BASF SE, 2014). Analytical monitoring could not be performed since the limit of quantification was above the water solubility of approx. 0.002 mg/L. The test substance is poorly soluble in water. Therefore, the test solutions were prepared following general guidance provided in OECD 23 in order to generate a saturated solution of the test substance in test medium. The volume of the test substance required for preparation of the nominal concentration was calculated from the density (d=0.8174 g/cm3).

And therefore, it can be concluded that has no chronic effect is expected towards aquatic invertebrates.
