Endpoint:
surface tension
Type of information:
experimental study
Adequacy of study:
key study
Study period:
November 2015
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.5 (Surface Tension)
Version / remarks:
Published in .J. L 142, 2008, using the OECD harmonized ring method for the measurement (Part 1.6.4)
GLP compliance:
no
Type of method:
ring method
Key result
Surface tension:
70.7 mN/m
Temp.:
20 °C
Conc.:
1 g/L
Conclusions:
The test substnace at apparent test cocentration of 1 gram per liter of redistilled water, shows corrected surface taension o 70.7 nN/M at 20 ºC (+/- 0.1 ºC).
As the surface tensin is higher than 60 mN/m, test substance should not be regarded as surface-active material.

Description of key information

The test substance shows corrected surface tension of 70.7 mN/m at 20ºC (+/- 0.1 ºC), at apparent test cocentration of 1 gram per liter of redistilled water.

As the surface tension is higher than 60 mN/m, the test substance should not be regarded as a surface-active material.

Key value for chemical safety assessment

Surface tension:
70.7
in mN/m at 20°C and concentration in mg/L:
1 000
