- 57.5 mN/m
- Temp.:
- 20 °C
- Conc.:
- 90 vol%
Any other information on results incl. tables
The mean results were based on the last five readings that had reached a plateau were as follows:
Mean Sample 1 result : 56.9 mN/m pH of Sample 1 : 6.0
Mean Sample 2 result : 57.8 mN/m pH of Sample 2 : 6.0
Overall result : 57.5 ± 1.0 mN/m
Overall temperature : 20.0 ± 0.5 ºC
Discussion:
According to criteria stated in EC Method A.5, substances showing a surface tension lower than 60 mN/m under the conditions of this method should be regarded as being surface active.
Applicant's summary and conclusion
- Conclusions:
- The surface tension of the test item at nominally 90 % saturation in water has been determined to be 57.5 ± 1.0 mN/m at 20.0 ± 0.5 °C. The test item was considered to be surface-active.
- Executive summary:
Surface Tension: 57.5 ± 1.0 (90% saturated solution) at 20.0 ± 0.5 ºC, using a ring method, designed to be compatible with Method A.5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for Testing of Chemicals, 27 July 1995. The test item was considered to be surface-active.
