Executive summary:

The surface tension of the test item was determined according to EU A5 guideline.


N,N-dimethyl-1-phenylmethanamine has a surface tension of 61.47 mN/m (Currenta, 2010).

Description of key information

Benzyldimethylamine has an experimentally measured surface tension of 61.47 mN/m (EU A5; Currenta, 2010).



Not regarded as a surface-active material (based on EU A5 criteria, > 60 mN/m).


Key value for chemical safety assessment

Surface tension:
61.47

Additional information

A guideline experimental study is available and therefore considered as key.


Temperature and test concentration are not specified, but assumed to be ca 20°C and 1 g/L (maximum test concentration, based on high solubility) acccording to guideline requirements.
