Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- Substance water soluble.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- ring method
- Specific details on test material used for the study:
- Appearance/Physical state: Orange liquid
Batch: 102-17 filtered
Purity: ca 50 % solution in water - Key result
- Surface tension:
- ca. 55.6 mN/m
- Temp.:
- 21 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension has been determined to be 55.6 mN/m at 21.0 ± 0.5 °C. The test item was considered to be surface-active.
It appears that the concentration reported refers to the test material as supplied and the 1 g/l of test material was actually 0.5 mg/l of the water-free substance
Either way, the result suggests some surface activity.
Reference
The surface tension of 1.0 g/L (0.5 g/l actives) solution of test item in water has been determined to be 55.6 mN/m at 21.0 ± 0.5 °C. The test item was considered to be surface-active.
Description of key information
The surface tension has been determined to be 55.6 mN/m at 21.0 ± 0.5 °C. The test item was considered to be surface-active.
It appears that the concentration reported refers to the test material as supplied and the 1 g/l of test material was actually 0.5 mg/l of the water-free substance
Either way, the result suggests some surface activity.
Key value for chemical safety assessment
- Surface tension:
- 55.6
- in mN/m at 20°C and concentration in mg/L:
- 500
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.
