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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The median particle size L50 of antimony trisulfide deduced from the particle size distributions is 32.7 µm.
The particle size L10 of antimony trisulfide deduced from the particle size distributions is 4.7 µm.
The particle size L90 of antimony trisulfide deduced from the particle size distributions is 100.4 µm.
Total Dustiness (airborne fraction): 0.40 mg/g (experimental results, DMT Report).
Mass median aerodynamic diameters (bi-modal distribution) of airborne fraction: MMAD1 = 7.69 µm (11.7%) , MMAD2 = 28.48 µm (88.3%) (distribution fitted to cascade impactor data, percentile in parentheses indicates weighting factor).
Geometric standard deviation of MMAD: GSD1 = 2.38, GSD 2 = 1.56
Fractional deposition in human respiratory tract (MPPD model, based on calculated MMAD):
Head (ET): 51.7%
Tracheobronchial (TB): 0.2%
Pulmonary (PU): 0.5%
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.
