Results and discussion
Surface tension
- Key result
- Surface tension:
- 62 mN/m
- Remarks on result:
- other: Temperature reported as room temperature (22-25 °C). Surface tension was determined using a solution that was 90% of the saturation solubility in water.
Applicant's summary and conclusion
- Conclusions:
- The surface tension of a test solution at 90% of saturation in water at room temperature (22-25 °C) is 62 mN/m (ASTM D1331-14).
- Executive summary:
The surface tension test of an aqueous solution of rosin acid derivative was determined using a plate method. A solution of rosin acid derivative was prepared at 90% saturation in water. The study was conducted according to test method ASTM D1331-14, but was not GLP compliant. Therefore this study is considered reliable with restrictions.
