Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The particle size distribution was performed by laser diffraction. The test substance was dispersed in water. The measurement concentration was approx. 130 mg/ml water. Triple determinations with always three measurement data were performed. For calculation of the particle size distribution, the Fraunhofer model was used.
