Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Version / remarks:
- based on ISO 304 Ring method
- Deviations:
- yes
- Remarks:
- The surface tension result was not corrected using the Harkins-Jordon correction table. Please see remarks.
- Principles of method if other than guideline:
- With the exception of the following deviation, the experimental procedure was carried out according to EU Method A.5 (Surface tension) with the exception of one deviation:
The surface tension was not corrected using the Harkins-Jordon table as the correction is not applicable to the apparatus used. Once calibrated the balance ring assembly used in this test gave a direct reading for surface tension that is within accuracy (±0.5 mN/m); this is as a result of reducing the ring dimensions.
The deviation is considered as to not have affected the integrity of the study. - GLP compliance:
- yes (incl. QA statement)
- Type of method:
- other: HPLC
Test material
Reference
- Name:

Results and discussion
Surface tension
- Surface tension:
- ca. 71.5 mN/m
- Temp.:
- 20.5 °C
- Conc.:
- 0 g/L
Any other information on results incl. tables
Mean reading = 71.9 mN/m
Surface tension = reading x calibrating factor = 71.9 x 0.995 = 71.5 mNm
Applicant's summary and conclusion
- Executive summary:
The surface tension of a 4.51 x 10 -4 g/l solution of Arakawa KE-604 has been determined to be 71.5 mN/m at 20.5 ± 0.5 °C. Arakawa is not considered to be a surface active material.
