- Deviations:
- yes
- Remarks:
- Sample was still turbid even after filtration and additional dilution. This was thebest possible and accepted This deviation was considered to have not impacted the overall integrity of the study or the interpretation of the study results and conclusions
- GLP compliance:
- yes
- Type of method:
- OECD harmonised ring method
- Key result
- Surface tension:
- ca. 47.2 mN/m
- Temp.:
- 20 °C
- Conc.:
- 90 other: Tested concentration: 90% of the saturation concentration
- Conclusions:
- The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20°C was 47.2 mN/m.
- Executive summary:
The OECD harmonized ring method was applied for the determination of the surface tension of the test item, according to EC A.5 and OECD Guideline No. 115
The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20°C was 47.2 mN/m.
According to this, the test item is considered to be surface active.

Description of key information
The obiective of the study was the determination of the surface tension of the itest item, according to EC A.5 and OECD Guideline No. 115
Specifically, the OECD harmonized ring method was applied
The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20°C was 47.2 mN/m.
Key value for chemical safety assessment
- Surface tension:
- 47.2
Additional information
Tested concentration: 90% of the saturation concentration
