Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Percentile:
D50
Mean:
>= 0.55 µm
Remarks on result:
other: Particle size and surface area depend very much upon the specific process and specific application(migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.)
Mean:
ca. 55 µm
Remarks on result:

Particle size and surface area depend very much upon the specific process and specific application.

Applicant's summary and conclusion

Conclusions:
Because of the chemical similarity of the candidate substance and cadmium oxide, it is considered that the likely particle size values reported for cadmium oxide are also applicable to the candidate substance.
