Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 g/L) of the test item at 20.0 ± 0.5 °C is 56.57 mN/m. Taking into account that the surface tension of the test item is below the trigger values of 60 mN/m, but the substance in an aqueous system is not expected to reduce the surface tension down to below 45 mN/m. Therefore the registered substance is NOT considered to be a surfactant.

Key value for chemical safety assessment

Surface tension:
56.57
in mN/m at 20°C and concentration in mg/L:
1 000
