Applicant's summary and conclusion

Conclusions:
The OECD harmonized ring method was applied for the determination of the surface tension of V173520.
The surface tension of a test solution at a concentration of 1 g/l in water and at 20°C was 69.1 mN/m. According to this, the test substance is considered not to be surface active.
