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: Standard method used however not conducted under GLP.
Qualifier:
according to guideline
Guideline:
other: Wilhelmy Plate
Deviations:
no
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
Type of method:
plate method
Key result
Surface tension:
25.9 mN/m
Temp.:
25 °C
Conc.:
100 vol%
Conclusions:
The measured surface tension at 25°C of Hydrocarbons, C10-C13, n-alkanes, isoalkanes, cyclics, aromatics (2-25%) is 25.9 mN/m using Wilhelmy plate method.
Executive summary:

The measured surface tension at 25°C of Hydrocarbons, C10-C13, n-alkanes, isoalkanes, cyclics, aromatics (2-25%) is 25.9 mN/m using Wilhelmy plate method.

Description of key information

The surface tension at 25°C of Hydrocarbons, C10-C13, n-alkanes, isoalkanes, cyclics, aromatics (2-25%) is between 25 and 27 mN/m using Wilhelmy plate method.
