Results
The readings, times and temperatures for the sample solutions are shown in the following tables:
Sample 1
| Age of Solution (min) | Reading (mN/m) | Temperature (°C) |
| 75 | 75 | 20 |
| 85 | 71.5 | 20 |
| 96 | 71 | 20 |
| 106 | 71.5 | 20 |
| 117 | 71.5 | 20 |
| 128 | 71 | 20 |
Sample 2
| Age of Solution (min) | Reading (mN/m) | Temperature (°C) |
| 144 | 73 | 20 |
| 155 | 70.5 | 20 |
| 165 | 71.5 | 20 |
| 176 | 71.5 | 20 |
| 186 | 71 | 20 |
| 196 | 71.5 | 20 |
| 207 | 71.5 | 20 |
Mean Sample 1 result : 71.3 mN/m (of last 5 results) pH of Sample 1 : 6.9
Mean Sample 2 result : 71.4 mN/m (of last 5 results) pH of Sample 2 : 6.9
Overall result : 71.5 ± 0.5 mN/m
Overall temperature : 20.0 ± 0.5 ºC
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 a nominally 90 % saturated solution of test item in water has been determined to be 71.5 ± 0.5 mN/m at 20.0 ± 0.5 °C. The test item was considered not to be surface-active.
- Executive summary:
Surface Tension: 71.5 ± 0.5 mN/m at 20.0 ± 0.5 °C (90 % saturated solution), 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 not to be surface-active.
