Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Executive summary:

Benzyldimethylamine has a water solubility of 8g/1000ml (Römpp, 2007).

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.
