Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2020-12-10
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Version / remarks:
- 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Version / remarks:
- 2008
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- ring method
- Key result
- Surface tension:
- 71.1 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1.012 g/L
- Conclusions:
- The mean surface tension was determined to be 71.1 mN/m.
- Executive summary:
The surface tension of the test item was determined in an experimental study under GLP conditions according to Regulation (EC) No 440/2008 Method A.5. and OECD Test Guideline 115 using the ring method. The surface tension was determined with a test item concentration of 1.0117 g/L at 20 °C. The mean surface tension was 71.1 mN/m. Due to the fact that the surface tension is higher than 60 mN/m, the test item is not regarded as surface-active.
