Details on results:
During this study the water solubility of the test item at 20 °C and at 37 °C were determined using the flask method and was found to be 9942.9 mg/L at 20 °C (after 72 hours of shaking) based on a measured concentration of 2684.6 mg Co/L and 17017.9 mg/L at 37 °C (after 144 hours of shaking) based on a measured concentration of 4594.8 mg Co/L using the flask shaking method.
Conclusions:
Interpretation of results (migrated information): soluble (1000-10000 mg/L)
