Data waiving: The study do es not need to be conducted as the substance is a solid

.

4.17 Stability in organic solvents

Data waiving: According to REACH regulation, Annex IX, column 2, the study does not need to be conducted as the substance is an inorganic salt.

4.21 Dissociation constant

Data waiving: The substance is an inorganic salt that can be expected to be dissociated at environmental relevant pH values.

4.22 Viscosity

Data waiving: According to REACH regulation, Annex XI, paragraph 2, the study does not need to be conducted as the substance is a solid and, thus, the test item is not subject to testing.
