- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and package No.of test material: lot #19953859
- Expiration date of the lot/batch: 16.01.2020 - Key result
- Surface tension:
- >= 31.85 - <= 31.85 mN/m
- Temp.:
- 20 °C
- Conc.:
- 397.2 mg/L
- Conclusions:
- As no clear solution could be obtained in water the surface tension could not be measured correctly due to poor water solubility of the substance. The surface tension is 31.85 mN/m
- Executive summary:
The surface tension is 31.85 mN/m
