Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 11 December 2017 to 01 June 2018
- 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
- Key result
- Surface tension:
- 43.5 mN/m
- Temp.:
- 20 °C
- Conc.:
- 90 vol%
- Conclusions:
- The surface tension of the test item was determined to be 43.5 mN/m based on a 90% saturated solution of the test item at 20°C.
- Executive summary:
The surface tension of the test item was determined in a study following OECD 115 and EC Method A.5 guidelines, using the OECD harmonised ring method. The surface tension of the test item was determined to be 43.5 mN/m based on a 90% saturated solution of the test item at 20°C.
The study is a GLP-compliant, guideline experimental study and is fully acceptable for assessment of this endpoint.

Harkins-Jordan corrected value = 43.5 mN/m
Description of key information
The surface tension of the test item was determined to be 43.5 mN/m for a 90% saturated solution at 20°C.
Key value for chemical safety assessment
- Surface tension:
- 43.5
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
The surface tension of the test item was determined in a study following OECD 115 and EC Method A.5 guidelines, using the OECD harmonised ring method (Dunning 2018). The study is a GLP-compliant, guideline experimental study and is fully acceptable for assessment of this endpoint.
