Results and discussion
Surface tension
- Surface tension:
- 57.3 mN/m
- Temp.:
- 20 °C
- Conc.:
- 0.072 g/L
- Remarks on result:
- other: Due to the fact that the surface tension is lower than 60 mN/m, the test item has surface-active properties.
Applicant's summary and conclusion
- Conclusions:
- The surface tension of the aqueous solution of the test item, stearic acid, cobalt salt, at 20 °C is sigma = 57.3 mN/m. Due to the fact that the surface tension is lower than 60 mN/m, the test item has surface-active properties.
