Details on results:
A preliminary non-GLP test was performed with a loading of 1.0 g/L test substance and resulted in a water solubility of ~12 mg/L. A main GLP test with a loading of 800 mg/L is still ongoing. The final results will be included with an update of the dossier.
Conclusions:
Fatty acid, tall-oil, manganese salts has a water solubility of ~186 mg/L at 20 °C.

Additional information

The study was commissioned at Fraunhofer Institute for Molecular Biology and Applied Ecology (Schmallenberg, Germany). The main experiment according to OECD 105 is currently ongoing according to GLP. Thus, results from the preliminary test of OECD 105 including the chemical quantification and results from the main test at days 1, 2, 3, 15, 16 and 17 of testing are included in the respective robust study summary. A dossier update is planned when the final study results will be made available.
