Description of key information
Zirconium dinitrate oxide is a white solid, under ambient conditions (Younis, 2015a, key study, Klimisch 1).
Key value for chemical safety assessment
- Physical state at 20°C and 1013 hPa:
- solid
Additional information
A GLP-compliant experimental study of reliability 1 according to Klimisch, dealing with relative density but reporting description of the registered substance, was selected as a key study (Younis, 2015a). The test item is described as a white solid.
Although the reference substance is a solid, the substance is also available and used as aqueous solution. Therefore, a supporting study was added (SDS MEL Chemicals, Klimisch 2) reporting on the appearance of a representative aqueous solution of the reference substance. The aqueous solution was yellow, and had a slight odour, at ambient temperature.
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.
