Materials and methods

Test guideline

Qualifier:

according to guideline

Guideline:

EU Method A.5 (Surface Tension)

Deviations:

yes

Principles of method if other than guideline:

The surface tension result was not corrected using the Harkins~Jordan correction table as the correction is not applicable to the apparatus used. Once calibrated, the balance and ring assembly used in this test give a direct reading for surface tension that is within the required accuracy(± 0.5 mN/m); this is as a result of the reduced ring dimensions. This deviation has been considered not to have affected the integrity of the study.

GLP compliance:

yes (incl. QA statement)

Type of method:

ring method

Remarks on result:

other: Substances having a surface tension below 60 mN/m are regarded as being surface-active.

Applicant's summary and conclusion

Conclusions:

The surface tension of a 1.01 g/l solution of test material has been determined to be 73.5 mN/m at 21.5 ± 0.5°C. The test material is considered not to be a surface-active material.

Executive summary:

Introduction

The study was conducted to assess the surface tension of the test material using a White Electrical Institute interfacial tension balance and a procedure based on the ISO 304 ring method which complies with Method A5 of commission Directive 92/69/EEC.

Results and conclusion

Substances having a surface tension below 60 mN/m are regarded as being surface-active. The surface tension of a 1.01 g/l solution of test material has been determined to be 73.5 mN/m at 21.5 ± 0.5°C. The test material is considered not to be a surface-active material.
