Description of key information

63.1 ± 0.2 mN/m @ 23 °C, 1 g/L
31.4 ± 0.1 mN/m @ 23 °C (pure substance)
32.22 mN/m @ 20 °C (pure substance)

Key value for chemical safety assessment

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

Additional information

Two sources reporting consistently similar values at ambient temperatures 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.
