Applicant's summary and conclusion

Conclusions:
The OECD harmonized ring method was applied for the determination of the surface tension of the substance. The surface tension of a test solution at 90% of the test substance saturation solubility in water and at 20°C was 61.2 mN/m. According to this, the substance is considered not to be surface active.
