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.
