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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- supporting 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:
- 27.2 mN/m
- Temp.:
- 25 °C
- Conc.:
- 100 vol%
- Conclusions:
- The measured surface tension was 27.2 mN/m at 25 °C using the Wilhelmy plate method.
- Executive summary:
The measured surface tension was 27.2 mN/m at 25 °C using the Wilhelmy plate method.
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- secondary literature
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Du Nouy ring method
- Surface tension:
- 26 mN/m
- Temp.:

Description of key information
Not surface active.
Key value for chemical safety assessment
Additional information
The requirement to conduct a surface tension study for the submission substance was waived in accordance with Column 2 of REACH Annex VII, because the test substance has a water solubility value which is <1 mg/l.
In addition, on the basis of structure, the substance is not expected to be surface active.
Supporting information for the neat substance indicates that the surface tension at 25°C is 25 to 29 mN/m according to the Wilhelmy plate testing methodology.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
