Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 a test solution of 1 g/l in water and at 20°C was 72.9 mN/m.

Key value for chemical safety assessment

Surface tension:
72.9
in mN/m at 20°C and concentration in mg/L:
1 000

Additional information

The surface tension of the test substance was determined under GLP according to OECD 115, the OECD harmonized ring method. Five measurements were performed until a constant value on the surface tension was reached (< 0.5 mN/m). The surface tension of a test solution of 1 g/l in water and at 20°C was 72.9 mN/m. According to this, the test substance is considered not to be surface active.
