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.
