Applicant's summary and conclusion

Conclusions:
The OECD harmonized ring method was applied for the determination of the surface tension of V125226.
The surface tension of a test solution at 90% of the test substance saturation solubility in water and at 20°C was 56.0 mN/m. According to this, the test substance is considered to be surface active.
