Results and discussion
Surface tension
- Surface tension:
- 72 mN/m
- Temp.:
- 20 °C
- Conc.:
- 90 other: % saturated
- Remarks on result:
- other: 90% saturated (approximately 7 mg/l, based on the determined water solubility value)
Applicant's summary and conclusion
- Conclusions:
- The surface tension of a 90% saturated aqueous solution of Phenylphosphonic acid, zinc salt was found to be 72.0 mN/m. As the result is greater than 60 mN/m, the test substance was not considered to be surface active.
