Description of key information

surface tension at 20 °C is between 57 mN/m and 70 mN/m (OECD 115). The mean value is 64 mN/n.

Key value for chemical safety assessment

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

Additional information

The surface tension of the aqueous solution of both tested substances with a different monoester / diester ratio is between 57.2 and 70.2 mN/m at 20°C.

Due to the fact that the lowest surface tension is lower than 60 mN/m, the substance has surface-active properties.
