Applicant's summary and conclusion

Conclusions:
The surface tension of the test item was determined to be 70.4 mN/m at 20°C for a concentration of 1 g/l.
Executive summary:

The surface tension was determined using the ring method according to the EU A.5 test guideline. The tests are run with a test item with a water solubility > 1 g/l, at constant 20°C, with two runs of 5 measurements, obtaining a mean value of the surface tension of 70.4 mN/m.
