Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
16.0 µm diameter at 12.2 % oversize
8.0 µm diameter at 66.3 % oversize
1.0 µm diameter at 97.1 % oversize
Additional information
The test substance could not be analysed in accordance with the OECD Guideline for Testing of Chemicals No. 110 "Particle Size Distribution/Fibre Length and Diameter Distributions".
The diameter in µm were:
16.0 at 12.2 % oversize
8.0 at 66.3 % oversize
1.0 at 97.1 % oversize
Median of mass distribution (diameter), mean of two analysis: 9.9 µm
The 8.1 % in volume of the test item has a particle size <= 4 µm (respirable fraction (the mass fraction of particles that reaches the alveoli) (respirable fraction - the mass fraction of particles that reaches the alveoli), as indicated in the CEN document, EN 481‘Workplace Atmospheres - size fraction definitions for measurement of airborne particles”, 1993.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
