Cerium tetrahydroxide

234-599-7regular dossiercovered by Cerium dioxide dossier2010

A SIEF communication was sent to explain why no separate REACH registration is needed for cerium hydrate (cerium tetrahydroxide).

The substance is covered by the cerium dioxide dossier, submitted in 2010 with Solvay as Lead Registrant.

The SIP was shared as well and can be found under the page of cerium dioxide. Further action to merge both SIEFs is ongoing.
