- Conclusions:
- The surface tension is 58.03 mN/m at 20.0 °C with a concentration of the test solution of 1.0 g/L. The test substance is surface-active.
- Executive summary:
In a GLP study according to 92/69/EEC Method A.5, the surface tension of the test substance in water was determined using the ring method. The surface tension is 58.03 mN/m at 20.0 °C at a concentration of the test solution of 1.0 g/L. The testsubstance is surface-active.
Reference
Target condition according to guideline: | Actual condition according to the study: | Validity criteria met: |
A solution of the substance is prepared in distilled water. The concentration of this solution should be 90 % of the saturation solubility of the substance in water; when this concentration exceeds 1 g/ L, a concentration of 1 g/ L is used for testing. | A concentration of 1 g/ L was used for testing as the water solubility of the test substance is 16.9 g/L. | yes |
The measurement shall be made at approximately 20°C and shall be controlled to within ± 0.5 °C. | Temperature during the measurement was 20.0 °C. | yes |
The measurement results: individual readings, their arithmetic mean and the corrected mean; concentration of the solution should be stated. | All values are reported. | yes |
