Description of key information

In accordance with Column 2 adaptation statement of REACH Annex VIII, hydrolysis as a function of pH, information requirement 9.2.2.1, does not need to be conducted if the test substance is inorganic in nature. Moreover given its high water solubility the substance is expected to ionize giving Ca2+ and IO3-.

Key value for chemical safety assessment

Half-life in freshwater:
900 h
at the temperature of:
25 °C
Half-life in freshwater sediment:
8 100 h
at the temperature of:
25 °C
