Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The studies performed and the available physicochemical data are consistent with an inorganic molecule with a very low bioavailability with no indication or evidence for potential for bioaccumulation.
The test item supplied was of a small particle size with a high surface area to mass ratio (~3 m2/g) so the lack of biological effects or bioavailability was not due to lack of intimate contact with the biological systems.
There were no studies that showed any bioavailability or bioaccumulation, in that there was no toxicity or evidence for absorption seen in any of the studies performed on biological systems.

Key value for chemical safety assessment

Bioaccumulation potential:
no bioaccumulation potential
