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:
- 30-09-2008 to 02-10-2008
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Guideline study performed under GLP. All relevant validity criteria were met.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- inspected: Novermber 2007; signature: April 2008
- Type of method:
- ring method
- Surface tension:
- 59.4 mN/m
- Temp.:
- 20 °C
- Conc.:
- 90 vol%
- Remarks on result:
- other: mean determined surface tension, multiplied by Φb (calibration factor) and with Harkins-Jordan correction
- Conclusions:
- The surface tension of a test solution at 90% saturation in water has been determined to be 59.6 mN/m at 20.0 ± 0.5 °C. The substance is considered to be surface-active.
- Executive summary:
The surface tension was determined using the ring method of EU Method A.5 and OECD 115 under GLP. Substances showing a surface tension lower than 60 mN/m under the conditions of this method, should be regarded as being surface active. The surface tension of a test solution at 90% of the test item saturation solubility in water has been determined to be 59.6 mN/m at 20.0 ± 0.5 °C. The substance is considered to be a surface-active.

Key value for chemical safety assessment
Additional information
Key study : EU Method A.5, 2008 : The surface tension was determined using the ring method of EU Method A.5 and OECD 115 under GLP. Substances showing a surface tension lower than 60 mN/m under the conditions of this method, should be regarded as being surface active. The surface tension of a test solution at 90% of the test item saturation solubility in water has been determined to be 59.6 mN/m at 20.0 ± 0.5 °C. The substance is considered to be a surface-active.
