Results and discussion
Surface tension
- Surface tension:
- 55.7 mN/m
- Temp.:
- 20.3 °C
- Conc.:
- 21.4 mg/L
- Remarks on result:
- other: in demineralized water. The applied concentration was determined from the weighted average mean of solubilities of individual components.
Applicant's summary and conclusion
- Conclusions:
- The mean surface tension of the test item at 21.4 mg/L in demineralized water was 55.7 ± 0.7 mN/m (corrected value).
The test item was considered to be surface-active under our experimental conditions.
