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:
- From October 2, 2009 to November 5, 2009
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Deviations:
- yes
- Remarks:
- The surface tension was not corrected using the Harkins-Jordan correction table as the correction is not applicable to the apparatus used.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Deviations:
- yes
- Remarks:
- The surface tension was not corrected using the Harkins-Jordan correction table as the correction is not applicable to the apparatus used.
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- ring method
- Key result
- Surface tension:
- 72.4 mN/m
- Temp.:
- 21 °C
- Conc.:
- 1.04 g/L
- Remarks on result:
- other: The test susbtance is not a surface active material
- Conclusions:
- Under the study conditions, the surface tension of the test substance was determined to be 72.4 mN/m at 21°C.
- Executive summary:
A study was conducted to determine the surface tension of the test substance according to EU Method A.5 and OECD Guideline 115, in compliance with GLP. An aqueous solution at ambient temperature of the test substance with a concentration of 1.04 g/L was prepared. Eight measurements at a temperature of 21°C, every 10 min, were done. The mean value was multiplied by the calibration factor. There was no correction with respect to the table given in EU Method A5 (Harkins-Jordan correction). Under the test conditions, the surface tension of the test substance was determined to be 72.4 mN/m at 21°C (Fox, 2009).
- Endpoint:
- surface tension
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because surface activity is not a desired property of the material
