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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 297-648-1 | CAS number: 93685-99-5 Oil shale waste is produced by thermal processing in a fluidized bed process at 800°C from mining exhausted oil shale. Oil shale waste consists essentially of Al2O3, CaO, CaSO4, Fe2O3 and SiO2.

Key value for chemical safety assessment
Additional information
In accordance with column 2 of REACH Regulation (EC) No 1907/2006, Annex VIII, the hydrolysis as a function of pH study (required in section 9.2.2.1) does not need to be conducted as the test substance is not chemically well defined and all the main components are not susceptible to hydrolysis. Due to the structural properties, the substance has no hydrolysable groups and therefore, it is concluded that hydrolysis neither is an important process in the fate of oil shale thermal processing residue nor has any considerable effect on the stability of the test substance during the aquatic toxicity studies performed with the substance.
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.
