Description of key information
Key value for chemical safety assessment
Justification for classification or non-classification
In order to evaluate toxicological properties of the substance erbium tetraoxide vanadium, information on the assessment entities erbium ions (i.e. erbium oxide) and vanadium ions were considered. For a documentation and justification of that approach, please refer to the separate document attached to section 13, namely Read Across Assessment Report for erbium tetraoxide vanadium.
The skin sensitisation potential of erbium tetraoxide vanadium may reasonably be considered to be determined by the bioavailability of the assessment entity "vanadium ions" since there are not any indications that the assessment entity “erbium ions” (i.e. erbium oxide) would be classified as hazardous for human health under Regulation (EC) No 1272/2008. Based on the outcome of sensitisation studies according to Magnusson and Kligman, it can be concluded that tetra-and pentavalent vanadium substances do not have a sensitisation potential and therefore must not be classified and labelled according to Regulation (EC) 1272/2008. Similarly, classification of erbium tetraoxide vanadium with respect to a the skin sensitisation potential does not appear to be supported. Thus, according to EC Regulation No. 1272/2008, erbium tetraoxide vanadium should not be considered to have a skin sensitisation potential, and hence classification or labelling is not 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.
