Applicant's summary and conclusion

Conclusions:
The OECD harmonized ring method was applied for the determination of the surface tension of V516690.
The surface tension of a test solution at a concentration of 1 g/L in water and at 20°C was 61.9 mN/m. According to this, the test item is considered not to be surface active
