Additional information


The hydrolysis study of the test item is not feasible with respect to the OECD Guideline 111, due to insolubility of the test item at test conditions. A slight hydrolysis of the undisolved test item was observed at pH 9.


Waiving according to "column 2" in Annex VII of REGULATION (EC) No 1907/2006. The study does not need to be conducted because the substance is inorganic.


Waiving according to "column 2" in Annex IX of REGULATION (EC) No 1907/2006. The study need not to be conducted if the substance has a low potential for bioaccumulation (for instance a log Pow < 3) and/ or a low potential to cross biological membranes.

Adsorption / desorption

The Adsorption/Desorption behavior of the test item could not be determined, as the test item is an inorganic substance that is nearly insoluble in water at the test conditions necessary for performing the study according to one of the guidelines OECD 121, OECD 106 and ISO 18479.
