Key result
Surface tension:
63.3 mN/m
Temp.:
20 °C
Conc.:
90 vol%

The surface tension of a test solution at 90% of the test substance saturation solubility in water and at 20°C was 63.3 mN/m.

Conclusions:
The test substance is considered not to be surface active.
Executive summary:

The OECD harmonized ring method was applied for the determination of the surface tension of the test item. The surface tension of a test solution at 90% of the test substance saturation solubility in water and at 20°C was 63.3 mN/m.

According to this, the test substance is considered not to be surface active.

Description of key information

The test substance is considered not to be surface active.

Key value for chemical safety assessment
