Description of key information

 

The inorganic substancezirconium sodium lactatewith structureZr(OH)4-x(CH3Na+O-CHCOO-)xis considered to be highly soluble in water.

In view of the nature of the substance and the availability of physical data available in the literature, we have considered the use of these data for the purpose of this report.

The main objective of the test work performed was to consider the potential for dissociation (dissolution) in water under biological and environmental conditions.
