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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because based on structure, surface activity is not expected or cannot be predicted
- Endpoint:
- surface tension
- Type of information:
- not specified
- Adequacy of study:
- other information
- Reliability:
- 3 (not reliable)
- Rationale for reliability incl. deficiencies:
- unsuitable test system
- Remarks:
- pure liquid
- Principles of method if other than guideline:
- not specified
- Surface tension:
- 15.45 mN/m
- Temp.:
- 25 °C
- Conc.:
- 100 vol%
- Surface tension:
- 17.1 mN/m
- Temp.:
- 10 °C
- Conc.:
- 100 vol%
- Executive summary:
The CRC Handbook provides a surface tension of 15.45 and 17.10 mN/m at 25 and 10°C respectively, for the pure substance.

Data relates to the pure liquid, not a solution as prescribed by OECD 115/EU A5 guideline.
Description of key information
No surface activity anticipated, based on chemical structure.
Key value for chemical safety assessment
Additional information
As the substance is an hydrocarbon, it does not contain groups (such as distinct polar and non-polar parts) indicating that it will have surface active properties in solution. Therefore, the study does not need to be conducted.
Literature (handbook) data is provided as addional information of scientific interest, but it relates to the pure substance, not a solution. So it is not relevant regarding the requirement of the present endpoint.
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.
