Endpoint summary
Administrative data
Description of key information
Skin sensitisation:
The substance is classified as corrosive to skin; therefore in accordance with column 2 of Section 8.3 of Annex VII of REACH Regulation 1907/2006 the study does not need to be conducted.
Respiratory sensitisation:
The evaluation of the monomer of dinitrogen tetraoxide, nitrogen dioxide, by MAK (2005) concluded that there is no evidence of sensitization of airways by NO2.
Key value for chemical safety assessment

Respiratory sensitisation
Endpoint conclusion
- Endpoint conclusion:
- no study available
Justification for classification or non-classification
There is no data which would indicate potential skin or respiratory sensitizing properties of dinitrogen tetraoxide (MAK, 2005). Therefore no classification is warranted.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
