Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- Experimental Starting Date: 24 July 2015 Experimental Completion Date: 29 September 2015
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- GLP compliance:

- Type of method:
- ring method
- Surface tension:
- 68 mN/m
- Temp.:
- 23.4 °C
- Conc.:
- 1 g/L
- Remarks on result:
- other: The surface tension of solutions prepared at nominally 1.0 g/L of test item in water has been determined to be 68.0 ± 0.5 mN/m at 23.4 ± 0.5 °C. The test item was considered not to be surface-active.
- Conclusions:
- The surface tension of solutions prepared at nominally 1.0 g/L of test item in water has been determined to be 68.0 ± 0.5 mN/m at 23.4 ± 0.5 °C. The test item was considered not to be surface-active.
- Executive summary:
The determination was carried out by a ring method, using a procedure designed to be compatible with Method A5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for the Testing of Chemicals, 27 July 1995.
Conclusion
The surface tension of solutions prepared at nominally 1.0 g/L of test item in water has been determined to be 68.0 ± 0.5 mN/m at 23.4 ± 0.5 °C. The test item was considered not to be surface-active.

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.
