The OECD harmonized ring method was used for the determination of the surface tension of MPKO. The surface tension of a test solution at a concentration of 1 g/L and at 20.2 °C was 69.5 mN/m. According to this, the test substance is considered not surface active.

Description of key information

69.5 mN/m at 20.2 °C and concentration of 1 g/L (ring method, OECD 115)

Key value for chemical safety assessment

Surface tension:
69.5
in mN/m at 20°C and concentration in mg/L:
1 000

Additional information

The substance is not surface active.
