Results and discussion

Water solubility
Water solubility:
< 0.05 mg/L
Temp.:
20 °C
pH:
5.8
Details on results:
For first main experiment column elution method was applied and leaded to water solubility below the detection limit of the analytical method. To achieve lower limits of detection flash method was performed instead and due to high variation of results at this low concentrations with reduction of flow to 12.5 ml/h. Flash method was also used to allow faster analysis to better cope with the high variation of results. After reaching equilibrium after 7 days in the 2nd test (6 individual vessel) water solubility resulted in:
< 0.4mg/l (colloidal solution)
< 0.05 mg/l (clear solution)

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): insoluble (< 0.1 mg/L)
insoluble in water
