Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusions:
Particle data was determined on the test substance with the majority of particles determined to be less than 100 µM and greater than 10 µM. The MMAD and GSD could not be determined.

Description of key information

Particle size of the test substance was initially determined by using a sieve followed by a cascade impactor method. The majority of particles determined to be less than 100 µM and greater than 10 µM. The MMAD and GSD could not be determined.
