Description of key information
The substance has no oxidising properties.
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
In a test for oxidising properties (acc. to the Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Part 34.4.1, Test O.1) both mixtures of the test item MoO3 with cellulose (4:1 and 1:1) had higher mean burning times compared to the reference mixture in the ratio 3:7. It is concluded that the test item pure MoO3 has no oxidizing properties.
In dipotassium tetraoxomolybdate and molybdenum trioxide the element molybdenum is in it’s highest oxidation state (6+). A GLP study according to the Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Part 34.4.1, Test O.1: Test for oxidizing solids results no oxidizing properties for molybdenum trioxide. This supports waiving of testing oxidizing properties for dipotassium tetraoxomolybdate and a non-classification.
Justification for classification or non-classification
In accordance with Annex I, Section 2.4, Section 2.13 and Section 2.14 of Regulation (EC) No 1272/2008 and UN GHS Rev 6 (2015) the substance has not to be classified as oxidising gas, oxidising liquid or oxidising solid in class 5 Division 5.1.
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.
