Applicant's summary and conclusion

Conclusions:
The surface tension of DEA polyborate was determined using the OECD harmonised ring method. The system consists of the following elements: model K6 tensiometer (Krüss, Hamburg, Germany), platinum-iridium ring with a wire radius of 0.185 mm and a ring radius of 9.545 mm and a cylindrical glass vessel with an inside diameter of 45 mm.
The surface tension of a test solution at a concentration of 1 g/L and at 20°C was 74.9 mN/m. According to this, the test substance is considered not to be surface active.
Executive summary:

The surface tension of DEA polyborate was determined using the OECD harmonised ring method. The surdace tension was found to be 74.9 mN/m.
