Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2017-04-04 to 2017-05-02
- 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)
- Version / remarks:
- version 1995
- Deviations:
- yes
- Remarks:
- test performed on a solution saturated instead on a solution at 90% of hydrosolubility because hydrosolubility was not determined (<460 mg/L) - this deviation does not affect the results obtained.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Version / remarks:
- version 2008
- Deviations:
- yes
- Remarks:
- test performed on a solution saturated instead on a solution at 90% of hydrosolubility because hydrosolubility was not determined (<460 mg/L) - this deviation does not affect the results obtained.
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- signed 23 March 2017
- Type of method:
- ring method
- Key result
- Surface tension:
- 63 mN/m
- Temp.:
- 20.1 °C
- Remarks on result:
- other: test performed on a solution saturated in test item.
- Conclusions:
- The mean surface tension of the test item saturated in distilled water at 20.1°C was 63.0 mN/m ± 0.6 mN/m. The test item was not considered as surface-active in the experimental conditions used.

Description of key information
The mean surface tension of the test item saturated in distilled water at 20.1°C was 63.0 mN/m ± 0.6 mN/m. The test item was not considered as surface-active in the experimental conditions used (OECD 115 guideline method).
Key value for chemical safety assessment
- Surface tension:
- 63
