Description of key information

In accordance with column 2 of REACH Annex VIII, the adsorption/desorption test (required in § 9.3.1) does not need to be conducted as the substance can be expected to have a low potential for adsorption. The substance is moderately soluble in water and has a low octanol water partition coefficient (log Pow = 0.6). However, a Koc value is required for the estimation of several PNECs. Therefore, Koc was estimated by a validated Q-SAR model using the molecular connectivity method (MCI) with the Kocwin 2.0 software. Dimethylethylamine has 3 aliphatic nitrogen to carbon bonds. It falls therefore in the scope of the MCI model, as indicated in appendix D of the user manual of Kocwin 2.0. Koc=14 L/kg

Dimethylethylamine is predicted as poorly sorptive under environmental conditions.
