Key result
Surface tension:
71.1 mN/m
Temp.:
20 °C
Conc.:
2.8 mg/L
Conclusions:
Surface tension: 71.1 mN/m at 20°C
Executive summary:

When tested according to OECD guideline 115 and EU method A.5, the surface tension of the test substance at 20°C was 71.1 mM/m, i.e., it is not surface active.

Determination 1: 71.3 mN/m

Determination 2: 70.2 mN/m

Determination 3: 69.5 mN/m

Determination 4: 70.5 mN/m

Mean: 70.4 mN/m (Corrected by calibration factor of 1.01 = 71.1 mN/m).
