- 66.5 mN/m
- Temp.:
- 20.1 °C
- Remarks on result:
- other: 90% of the test saturation solubility in water was used
Applicant's summary and conclusion
- Conclusions:
- The OECD harmonized ring method was used for the determination of the surface tension of the test item. The surface tension of a test solution at 90% of the test substance saturation solubility in water and at 20.1 °C was 66.5 mN/m.
According to this, the test substance is considered not surface active.
