Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- 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:
- no
- Type of method:
- OECD harmonised ring method
- Key result
- Surface tension:
- 56.19 mN/m
- Temp.:
- 20.2 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension of the test item was determined to be 56.19 mN/m at 20 °C.
- Executive summary:
The surface tension of the test item was determined in an experimental study according to Regulation (EC) No 440/2008 Method A.5. and OECD Test Guideline 115 using the harmonized OECD ring method. The surface tension was determined with a test item concentration of 1 g/L at 20 °C. The mean surface tension was 56.19 mN/m. Due to the fact that the surface tension is lower than 60 mN/m, the test item is regarded as being surface-active.

Additional information
The surface tension of the test item was determined in an experimental study according to Regulation (EC) No 440/2008 Method A.5. and OECD Test Guideline 115 using the harmonized OECD ring method. The surface tension was determined with a test item concentration of 1 g/L at 20 °C. The mean surface tension was 56.19 mN/m. Due to the fact that the surface tension is lower than 60 mN/m, the test item is regarded as being surface-active.
