surface tension
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2011
Reliability:

Justification for type of information:
The surface tension of the test substance was determined using the OECD harmonized 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.

Applicant's summary and conclusion

Conclusions:
The surface tension of a test solution at a concentration of 1 g/l in water and at 20°C was 71.9 mN/m.
According to this, the test substance is considered not to be surface active
