Applicant's summary and conclusion
- Conclusions:
- The surface tension of a 1 g/L dilution of the test substance in water was determined to be 43.8 mN/m at 20.1 °C.
- Executive summary:
The aim of the study was the determination of the surface tension of the test item in water at 20 °C ± 0.5 °C according to EC method A.5 and OECD 115 using the ring method. The test was performed twice.
The mean surface tension of a 1 g/L dilution of the test substance in water was determined to be 43.8 mN/m at 20.1 °C.
