Description of key information
The particle size distribution of quinine base, anhydrous sample #1 is < 250 µm and the particle size distribution of sample #2 is < 63 µm. The mass median diameter of quinine is in a range of 24 - 28µm.
Additional information
In this study report, the particle size distribution of quinine was determined for two samples. The particle size distribution of quinine base, anhydrous sample #1 is < 250 µm and the particle size distribution of sample #2 is < 63 µm. In sample #2 lower particles sizes were measured, so that this sample is more conservative for prediction the dustiness. With regard to inhalation potential, 100 % can be inhaled (<100 µm). 38 % of quinine has a particle size < 20 µm. Therefore, the alveoli relevant respirable fraction (<10 µm) is <38%. The mass median diameter is in a range of 24 - 28 µm.
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.
