Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Categories
- Category name:
- Lanthanum and aluminium oxides (sparingly soluble)
Justifications and discussions
- Category definition:
- Lanthanum and aluminium oxides (sparingly soluble)
- Category description:
- Lanthanum and aluminium oxides (sparingly soluble)
- Category rationale:
- In a category approach, read-across is used among a number of structurally similar substances, i.e. sparingly soluble aluminium ansd lanthanum oxides. The structural similarity is based on the fact that the common (eco)toxicological moieties of concern are the aluminium and lanthanum ions. Within this category, as a result of the structural similarity, the specified toxicological and ecotoxicological properties are similar.
The similarity rules specified in Annex XI, Section 1.5 of the REACH Regulation in the REACH Guidance on IR & CSA, Chapter R.6 of apply and the category ”lanthanum and aluminium oxides (sparingly soluble)” is formed.
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.
