Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

The surface tension of an aqueous solution (1.08 g/l solution) is 72.1 mN/m.

Key value for chemical safety assessment

Surface tension:
72.1
in mN/m at 20°C and concentration in mg/L:
1 080

Additional information

The surface tension was measured at 21.5 °C but the value at 20 °C will not be far from it and the conclusion does not change: this substance is not considered to be surface-active.
