Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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:
No GLP certified lab.
Type of method:
plate method
Key result
Surface tension:
22.9 mN/m
Temp.:
25 °C
Conc.:
100 vol%
Conclusions:
The measured surface tension for the substance at 25°C is 22.9 nm/m.
Executive summary:

The measured surface tension for the substance at 25°C is 22.9 nm/m.

Description of key information

The surface tension at 25°C is between 22 and 24 mN/m.

Key value for chemical safety assessment
