Description of key information

Additional information

Ammonium zirconium carbonate (AZC)is inorganic and hence the ready biodegradation and hydrolysis tests are not relevant. This is because there is no carbon to be evolved and no chemical bonds to be broken, respectively. It is also not technically feasible to conduct a hydrolysis study AZC only ever exists as a solution in water across a narrow pH range. If removed from this range then AZC does not exist in the form to be registered.

In environmentally-relevant conditions there is expected to be decomposition of the substance to form zirconium hydroxide, together with accompanying release of carbonate and ammonium ions.
