Description of key information

70.7 mN/m (23 °C, 1 g/L), key study
24.6 mN/m (20 °C, no concentration stated)
24.8 mN/m (20 °C, 100%)
24.61 mN/m (20 °C, 100%)

Key value for chemical safety assessment

Surface tension:
in mN/m at 20°C and concentration in mg/L:
1 000

Additional information

Several literature sources reporting consistently similar values at 20°C for the pure substance. However, as key parameter the value determined at 23 °C at a concentration of 1 g/L was chosen. This result was obtained in a guideline study, experimental details are well documented.
