Description of key information
N,N-dimethylbenzylamine has a water solubility of 8 g/L at 20°C (Römpp, 2007).
This is assumed to correspond to the solubility of the non-ionised form.
Key value for chemical safety assessment
- Water solubility:
- 8 g/L
- at the temperature of:
- 20 °C
Additional information
Four reliable literature data sources were identified, and three provide consistent water solubility values, ranging between 8 and 12 g/L. For Lide (2008-2009), only a qualitative assessment was provided. However, in all of them, the information of pH was missing, so they were regarded as Supporting data only, due to pKa falling into the environmentally-relevant pH range (pKa = 8,9; see IUCLID section 4.21).
Römpp (2007) was selected as Key, as the temperature was specified.
The magnitude of order was confirmed by QSAR prediction (BFS, 2023), for the non-ionised form to be consistent with logKow determination. But since this form is not relevant in actual environmental pH conditions, it was kept as Supporting too.
