Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
25.52 % of the particles had a diameter of < 100 μm which belongs to the inhalable fraction (the mass fraction of particles that can be inhaled by nose and mouth). However, only 3.04 % of the particles had a diameter of < 10 μm, which belongs to the thoracic fraction (the mass fraction of particles that passes the larynx) and only 2.98% had a diameter of < 5 μm, which belongs to the respirable fraction (the mass fraction of particles that reaches the alveoli). Consequently, approximately 75% of the particles are not included in the inhalable convention because they have a diameter that ranges from 100 – 500 μm.
Additional information
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.
