Endpoint:
surface tension
Type of information:
experimental study
Adequacy of study:
key study
Study period:
08 October 2018 (experimental starting date) - 06 November 2018 (experimental completion date)
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
comparable to guideline study
Qualifier:
equivalent or similar to
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Version / remarks:
27 July 1995
Qualifier:
equivalent or similar to
Guideline:
EU Method A.5 (Surface Tension)
Version / remarks:
30 May 2008
GLP compliance:
yes (incl. certificate)
Type of method:
ring method
Surface tension:
65 mN/m
Temp.:
20 °C
Conc.:
100 vol%
Conclusions:
According to criteria stated in EC Method A.5, 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 the test item at nominally 1 g/L in water has been determined to be 65 ± 3 mN/m at 20.0 ± 0.5 °C. The test item was considered to be not surface-active.
Executive summary:

The surface tension of the test item at nominally 1 g/L in water has been determined to be 65 ± 3 mN/m at 20.0 ± 0.5 °C. The test item was considered to be not surface-active.
