Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Conclusion on classification

Studies performed with the substance

In 3 short-term studies performed in accordance with the current OECD guidelines, up to a concentration present in a 0.45 μm filtered solution prepared at a loading rate of 100 mg/L, the substance did not induce visible or lethal effects in carp, did not induce acute immobilisation of Daphnia magna and did not reduce the growth rate of Pseudokirchneriella subcapitata. Classification of the substance based on the performed studies with the substance is therefore not considered needed.

Metal compounds strategy

The substance is an inorganic substance containing metals (Ce, Tb, Mg and Al). Consequently any classification based on the metals strategy presented in the Guidance on the Application of the CLP criteria should be investigated. In case of this substance any classification based on the Ce, Tb, Mg and/or Al ions need to be investigated, considering the rate (and extent) of transformation/dissolution of these elements from the substance.

The substance is insoluble in water. Experiences made during the development of an ICP-MS method for analysis of the substance in test media (see IUCLID section 8) have shown that very harsh conditions are needed to decompose the substance into its metal ions. For this, a mixture of strong mineral acids in combination with microwave digestion are needed, as well as a temperature of up to 225°C. Under environmental conditions the substance will not decompose and the rate of dissolution of metal ions from the substance is consider to be slow (if any).

Based on these considerations, it is not considered scientifically justified to perform the study Transformation/Dissolution of Metals and Metal compounds in aqueous media according to Annex 10 of UN GHS, to further investigate dissolution of metal ions from the substance. The substance will remain stable under the conditions of this study. Classification of the substance based on the metals contained in the substance is therefore not considered needed.
