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.
