Measurement	Time passed after measurement start [seconds]	Surface tension (mN/m)
		individual	mean multiplied by σ and Harkins-Jordan corrected value
1	37.20	54.45	54.38
2	62.38	54.39
3	88.00	54.38
4	113.34	54.36
5	141.12	54.30

Conclusions:

The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20°C was 54.38 mN/m. According to this, the test item is considered to be surface active.

Executive summary:

The OECD harmonized ring method was applied for the determination of the surface tension of the test substance.

The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20°C was 54.38 mN/m. According to this, the test item is considered to be surface active.
