Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- Testing was conducted between 15 June 2011 and 20 December 2011.
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- Study conducted in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not affect the quality of the relevant results. The study report was conclusive, done to a valid guideline and the study was conducted under GLP conditions.
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Version / remarks:
- The surface tension was determined using a ring method based on ISO 304
- Deviations:
- yes
- Remarks:
- The surface tension result was not corrected using the Harkins-Jordan correction table as the correction is not applicable to the apparatus used.
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Version / remarks:
- The surface tension was determined using a ring method based on ISO 304
- Deviations:
- yes
- Remarks:
- The surface tension result was not corrected using the Harkins-Jordan correction table as the correction is not applicable to the apparatus used.
- 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
- Key result
- Surface tension:
- 70.7 mN/m
- Temp.:
- 21.5 °C

- Key result
- Surface tension:
- 70.5 mN/m
- Temp.:
- 21.2 °C
- Conc.:
- 0.976 g/L
- Remarks on result:
- other: Concentration corrected for Water Content (g/L)
- Conclusions:
- The surface tension of the test item has been determined as follows:
Concentration corrected for water content (g/l) Surface Tension (mN/m) Temperature (ºC)
0.976 70.5 21.0 ± 0.5ºC
1.00 70.7 21.5 ± 0.5ºC
The test item is not considered to be surface-active. - Executive summary:
The determination was carried out using a White Electrical Institute Co. Ltd. torsion balance for surface and interfacial tension measurements and a procedure based on the ISO 304 ringthod. With the exception of the following deviation, the experimental procedure used was designed to be compatible with that specified in Method A5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for the Testing of Chemicals, 27 July 1995.
§ 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.
