Description of key information

Based on tests according to EU Method A.5 (Surface Tension) the surface tension of Diketon is 66.8 mN/m at 20°C. Therefore Diketon is not considered to be surface active.

Key value for chemical safety assessment

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

Additional information

A weak time dependence of the surface tension of the test solutions was measured within the experimental time.

Hydrolysis did not influence the surface tension of the test solution during a time interval of 4 days.
