Applicant's summary and conclusion

Conclusions:
The OECD harmonized ring method was applied for the determination of the surface tension of nadide.
The surface tension of a test solution at a concentration of 1 g/l in water and at 20°C was 73.0 mN/m.
According to this, the test substance is considered not to be surface active.
Executive summary:

The surface tension of the test substance was determined using the OECD harmonized ring method.

A test solution of the test substance was prepared in double distilled water at a concentration of 1 g/l. Five measurements

were performed until a constant value on the surface tension was reached (0.5 mN/m). The time passed since the solution was transferred to the measurement vessel was measured for each measurement.

The test was performed at 20.0 ± 0.5°C.

A test substance with a surface tension < 60 mN/m will be regarded as being a surface active material.

The surface tension of a test solution at a concentration of 1 g/l in water and at 20°C was 73.0 mN/m.

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