- Justification for type of information:
- Zinc oxide is already oxidized and chemically stable so by essence, the substance cannot react with oxygen, even if heated.
Justification in Outotec REPORT - March 11, 2010 - 10043-ORC-T section 7 and 9, attached
This justification applies to both sets of nanos: the "Zinc oxide nano with and without hydrophilic surface treatment" set and the "Zinc oxide nano - hydrophobic surface treatment" set.

Description of key information
Zinc oxide is already oxidized and chemically stable so by essence, the substance cannot react with oxygen, even if heated.
Based on the thermogravimetric and differential scanning calorimetric measurements and mineral composition the substance has no flammability, explosiveness or auto-inflammability properties.
Key value for chemical safety assessment
