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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
The environmental fate and behaviour of the registered substance was determined via an expert examination of the hydrolysis of its constituents which concluded that Cordierite, sintered, synthetic is hydrolytically stable. Since the substance is inorganic the concept of biodegradation is irrelevant. The study of the solubility of Cordierite has shown dissolution of surface ions which are not further degradable which indicate that there is “no need to investigate further the degradation of the substance and its degradation products". Similarly, Bioaccumulation is a concept that does not apply to the hazard assessment of inorganic substances. In water Cordierite dissociates in ions which are found naturally in the water and that are not deemed to be bioaccumulative. The determination of Koc and Kow, is not technically possible. The required test methods are not applicable to molecules which dissociate. Following dissociation in water, resultant ions are expected to undergo ion exchange within the soil and water. Therefore, this endpoint is not relevant for inorganic substances that dissociate.
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.
