- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- OECD harmonised ring method
- Key result
- Surface tension:
- 62.8 mN/m
- Temp.:
- 20 °C
- Conc.:
- 90 other: vol% of the test item saturation solubility in water
- Remarks on result:
- other: mean multiplied by Φb and Harkins-Jordan corrected value
- Conclusions:
- The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20°C was 62.8 mN/m. According to this, the test item is considered not to be surface active.
- Executive summary:
The OECD harmonized ring method was applied for the determination of the surface tension of the test item according to OECD Guideline 115 and EU Method A.5. The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20°C was 62.8 mN/m. According to this, the test item is considered not to be surface active.

Description of key information
The OECD harmonized ring method was applied for the determination of the surface tension of the test item according to OECD Guideline 115 and EU Method A.5. The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20°C was 62.8 mN/m. According to this, the test item is considered not to be surface active.
Key value for chemical safety assessment
- Surface tension:
- 62.8
Additional information
One reliable experimental study is available and is selected as key study (Charles River, 2018). It was performed according to OECD Guideline 115 and EU Method A.5, and under GLP principles.
