Applicant's summary and conclusion
- Conclusions:
- The surface tension of a solution of test material has been determined to be 58.6 mN/m at 21.5 ± 0.5°C.
- Executive summary:
- Method: The
determination was carried out using a White Electrical Institute
interfacial tension balance and a procedure based on the ISO 304 ring
method. With the exception of the following deviation, the experintal
procedure used complied with that specified in Method A5 Surface Tension of
Commission Regulation (EC) No 440/2008 of 30 May 2008.
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.
Results:
Mean reading : 58.6 mN/m
Surface tension = reading x calibration factor
= 58.6 x 1.000
= 58.6 mN/mConclusion:
The surface tension of a solution of test material has been determined to be 58.6 mN/m at 21.5 ± 0.5°C. The test material is considered to be a surface-active material as defined by the method guideline, although no surface active properties were observed within a two phase water/n-octanol system whilst under investigation. The sample solution concentrations on analysis were as detailed in the following table:
