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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- read-across from supporting substance (structural analogue or surrogate)
- 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.
- Justification for type of information:
- A discussion and report on the read across strategy is given as an attachment in IUCLID Section 13.
- Reason / purpose for cross-reference:
- read-across: supporting information
- 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
- Type of method:
- plate method
- Key result
- Surface tension:

Description of key information
There is no data available for Hydrocarbons C12-C18, isoalkanes, cyclics, 2-30% aromatics. However, data is available for structural analogues, Hydrocarbons, C14-C18, n-alkanes, isoalkanes, cyclics, 2-30% aromatics and Hydrocarbons, C16-C20, n-alkanes, isoalkanes, cyclics, 2-30% aromatics and presented in the dossier. This data is read across to Hydrocarbons C12-C18, isoalkanes, cyclics, 2-30% aromatics based on analogue read across and a discussion and report on the read across strategy is provided as an attachment in IUCLID Section 13.
The surface tension of Hydrocarbons, C14-C18, n-alkanes, isoalkanes, cyclics, 2-30% aromatics at 25°C is 28 to 30 mN/m according to the Wilhelmy plate testing methodology.
The surface tension of Hydrocarbons, C16-C20, n-alkanes, isoalkanes, cyclics, 2-30% aromatics at 25°C is 28 to 31 mN/m according to the Wilhelmy plate testing methodology.
