Description of key information

Additional information


Based on the available experimental data of the structurally analogous substance TETA, adsorption to solid soil phase is indicated (geometric mean log Koc = 3.49; Koc = 3090.3 L/kg; Akzo Nobel, 2010). In terms of a worst-case approach, these data were selected for the assessment (PNEC derivation).

However, since 3,3'-iminodi(propylamine) is readily biodegradable and has a low log Kow of -1.25, it is not expected to adsorb to the solid phase.

Henry's Law Constant

From the water surface, the substance will not evaporate into the atmosphere.


The data refer to the uncharged molecule. However, as the substance will be ionized at environmentally relevant pH(estimated pKa value: 10.7,BASF SE 2017), the distribution into water may still be underestimated by the model.
