Reference
Endpoint:
surface tension
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2010
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Acceptable, well-documented study report which meets basic scientific principles, no GLP lab.
Qualifier:
according to guideline
Guideline:
other: Wilhelmy plate method
Principles of method if other than guideline:
Wilhelmy plate method is used to measure the surface tension using a standardized plate with a ring/plate tensiometer. The plate is moved towards the surface until the meniscus connects with it. The surface tension is calculated from the resulting force. Due to uncertain wetting behavior, the plate can only be used for interfaces under certain limitations.
GLP compliance:
no
Remarks:
Non GLP certified lab
Type of method:
plate method
Surface tension:
23.3 mN/m
Temp.:
25 °C
Conc.:
100 vol%
Conclusions:
The measured surface tension was 23.3 mN/m at 25 °C using the Wilhelmy plate method.
Executive summary:

The measured surface tension was 23.3 mN/m at 25 °C using the Wilhelmy plate method.

Description of key information

The surface tension at 25 deg C is 22 to 26 mN/m according to the Wilhelmy plate testing methodology. 

Key value for chemical safety assessment

Additional information

The surface tension at 25 deg C is 22 to 26 mN/m according to the Wilhelmy plate testing methodology.
