Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Mass median diameter: 18.74-19.3 µm
Mass median aerodynamic diameter: 19.02 µm

Additional information

The particle size distribution of the test substance was assessed using a Laser Diffraction Particle Size Analyser.

The following results were obtained:

d10: 2.125 μm

d50: 11.346 μm

d90: 31.939 μm

Coefficient of variation for d50 is less than 3%; d10 and d90 are less than 5%. Thus repeatability of the characterisitic particles in the size distribution are within the acceptable limits as per the ISO 13320 -1 test standard.

The Mass median aerodynamic diameter is 19.02 μm.
