Applicant's summary and conclusion

Conclusions:
The OECD harmonized ring method was applied for the determination of the surface tension of 2,2,2-trifluoro-1-(trifluoromethyl)ethyl methacrylate.
The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20°C was 74.1 mN/m. According to this, the test item is considered not to be surface active.
