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
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- OECD harmonised ring method
- Surface tension:
- 72.6 mN/m
- Temp.:
- 20 °C
- Conc.:
- 90 vol%
- Remarks on result:
- other: % saturation solubility in water
- Conclusions:
- The surface tension of a test solution at 90% of the test item saturation solubility in water (at 20°C) was 72.6 mN/m. Accordingly the test item is considered not to be surface active.

Description of key information
The surface tension of the test substance was determined in a GLP compliant test in accordance with EU method A.5 and OECD 115.
Key value for chemical safety assessment
- Surface tension:
- 72.6
Additional information
The test substance is considered not to be surface active.
