- Surface tension:
- 70.2 mN/m
- Temp.:
- 20.3 °C
- Remarks on result:
- other: corrected mean surface tension at 90 % of the saturation concentration
- Conclusions:
- The mean surface tension of a dilution from 90 % of the saturation concentration in water of test item was determined to be 70.2 mN/m at 20.3 °C.
- Executive summary:
The aim of the study was the determination of the surface tension of the test item as a dilution of 90 % of the saturation concentration in water at 20 °C ± 0.5 °C according to EC method A.5 and OECD 115 using ring method. The test was performed twice.
The mean surface tension of a dilution from 90 % of the saturation concentration in water of test item was determined to be 70.2 mN/m at 20.3 °C.
Reference
The test was performed twice at a temperature of 20.4 °C (test 1) and 20.1 °C (test 2).
