Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

As an inorganic substance, reaction mass of cerium dioxide and lanthanum oxide and lanthanum fluoride is not biodegradable. As none of the constituents should not show any potential for bioaccumulation, a similar expectation can be drawn out for the reaction mass. Short-term tests performed on the three trophic levels (i.e. fish, daphnids, algae) do not reveal any acute toxicity of reaction mass of cerium dioxide and lanthanum oxide and lanthanum fluoride. Furthermore, the long-term data on cerium dioxide and lanthanum oxide with daphnids, which can be used in read-across for the reaction mass, indicates both constituents present no chronic adverse effects on this species. As a result, reaction mass of cerium dioxide and lanthanum oxide and lanthanum fluoride will not be classified regarding its environmental impacts, neither under the criteria of CLP, nor under those of DSD.
