Applicant's summary and conclusion

Conclusions:
The surface tension of a Tetraethylammonium tetrafluoroborate at a concentration of 1 g/L in water and at 20°C was 72.07 mN/m. According to this, the test item is considered not to be surface active.
Executive summary:

The OECD harmonized ring method was applied for the determination of the surface tension of Tetraethylammonium tetrafluoroborate. The surface tension of the test item was determined using the tensiometer. The test was performed at 20.0 ± 0.5°C.

The surface tension of a test solution at a concentration of 1 g/L in water and at 20°C was 72.07 mN/m. According to this, the test item is considered not to be surface active.
