Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 269-057-9 | CAS number: 68186-95-8 An inorganic pigment that is the reaction product of high temperature calcination in which zirconium (IV) oxide, silicon oxide, and vanadium (IV) oxide in varying amounts are homogeneously and ionically interdiffused to form a crystalline matrix of zircon. Its composition may include any one or a combination of the modifiers alkali or alkaline earth halides.

Additional information
The pigment zirconium vanadium blue zirconis environmentally and biologically inert due to the characteristics of the synthetic process (calcination at high temperatures, approximately 1000°C), rendering the substance to be of a unique, stable crystalline structure in which all atoms are tightly bound and not prone to dissolution in environmental and physiological media.Based on the resulting physico-chemical properties, especially the high insolubility of the pigment under environmental conditions, demonstrated (by Pardo Martínez, 2013) via transformation/dissolution testing (7 and 28 days), the substance can be expected to not have a potential to cross or adsorb to biological membranes. Therefore, no reversible or irreversible adverse toxicological effects on aquatic or terrestrial life-forms are expected, and a PNEC derivation is scientifically not justifiable.
Conclusion on classification
Based on the high insolubility of the pigment under environmental conditions, demonstrated (byPardo Martínez, 2013) via transformation/dissolution testing (7 and 28 days), no reversible or irreversible adverse toxicological effects on aquatic or terrestrial organisms are expected. Hence no environmental classification is required.
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.
