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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: Standard method used however not conducted under GLP.
- 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
- 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
- Remarks:
- Not specified
- Type of method:
- plate method
- Key result
- Surface tension:
- 26.1 mN/m
- Temp.:
- 25 °C
- Conc.:
- 100 vol%
- Conclusions:
- The measured surface tension at 25°C is 26.1 mN/m using Wilhelmy plate method.
- Executive summary:
The measured surface tension at 25°C of Hydrocarbons, C14-C19, isoalkanes, cyclics, <2% aromatics is 26.1 mN/m using Wilhelmy plate method.

Description of key information
There is no data available for Hydrocarbons, C13-C16, isoalkanes, <2% aromatics. Data is available for Hydrocarbons C14-C19, isoalkanes, cyclics, <2% aromatics and based on an analogue approach, this data is used for read across to Hydrocarbons, C13-C16, isoalkanes, <2% aromatics.
The surface tension at 25°C of Hydrocarbons, C14-C19, isoalkanes, cyclics, <2% aromatics is between 25 and 30 mN/m using Wilhelmy plate method.
Key value for chemical safety assessment
Additional information
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.
