Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 14 March 2017 - 09 November 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- Study was conducted in accordance with international guidelines and in accordance with GLP. All guideline validity criteria were met.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Version / remarks:
- Regulation (EC) 440/2008 of 30 May 2008
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Version / remarks:
- 27 July 1995
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- OECD harmonised ring method
- Key result
- Surface tension:
- 34 mN/m
- Temp.:
- 20.4 °C
- Conc.:
- 1 g/L
- Remarks on result:
- other: Mean corrected surface tension value.
- Surface tension:
- 33.9 mN/m
- Temp.:
- 20.3 °C
- Conc.:
- 1 g/L
- Remarks on result:
- other: Test 1
- Remarks:
- Mean value of five measured surface tension values.
- Surface tension:
- 34 mN/m
- Temp.:
- 20.4 °C
- Conc.:
- 1 g/L
- Remarks on result:
- other: Test 2
- Remarks:
- Mean value of five measured surface tension values.
- Conclusions:
- The mean of two determinations of the surface tension of a 1 g/l solution of the test item in water was determined to be 34.0 mN/m at 20.4 °C.
- Executive summary:
EU Method A.5. – The surface tension of the test item was determined using the OECD harmonised ring test method. The procedure employed was designed to be compatible with Method A.5. Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008.
An instrumentation calibration was performed using ultra-pure water and a calibration factor determined. Duplicate 1 g/l solutions of test item in ultra-pure water, were prepared, introduced to the appliance and thermally equilibrated to 20 °C 0.5 °C. Two tests were carried out, the surface tension of each solution was measured repeatedly until the standard deviation of the last five determinations was equal or lower than 0.1 mN/m.
The mean surface tension following measurement of duplicate 1 g/l solutions of test item in ultra-pure water was determined to be 34.0 mN/m at 20.4 °C.
