Description of key information

Key value for chemical safety assessment

Skin sensitisation

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not sensitising)
Additional information:

The relatively low lipid solubility of Zr metal limits absorption through the skin. Soluble forms of Zr are more readily absorbed since the metal ion is the entity absorbed. Based on the animal and human data available, a read across with ZrO2 data is possible as both insoluble and active forms did not induce any sensitizing response.

A reliable study (Klimisch 2) is available and tested the sensitization potential of ZrO2, substance with the same behaviour as Zr: no effects were observed in this test. This result is confirmed by the observations made on humans exposed to several doses of ZrO2, with no skin reaction observed.


Migrated from Short description of key information:
No data is available on the sensitisation of Zirconium metal. Based on the same toxicity, a read across with ZrO2 was performed. The substance is not a skin sensitisation substance.

Respiratory sensitisation

Justification for classification or non-classification

Based on the available data, the substance was not classified under the CLP Regulation 1272/2008 and the directive Classification and Labeling 67/548.
