Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key result
Surface tension:
ca. 52.2 mN/m
Temp.:
20 °C
Conc.:
1 g/L
Conclusions:
The surface tension of nominally 1 g/L solutions of the substance in water has been determined to be 52.2 mN/m at 20. ± 0.5 °C, using a ring method. The substance was considered to be surface-active.
Executive summary:

The surface tension of nominally 1 g/L solutions of the substance in water has been determined to be 52.2 mN/m at 20. ± 0.5 °C, using a ring method. The substance was considered to be surface-active.
