Description of key information
The MMAD (Mass Median Aerodynamic Diameter < 100 μm) has a value for the substance of 10.57 μm as spherical particles.
Additional information
According to OECD guideline 110, method B, the particle size distribution of the substance was determined by scanning electron microscopy method for the sieved fraction (< 100 µm, 0.22 % of total sample) and presented on the basis of calculated mass fractions. The median diameter was 10.57 µm with two main fractions of 40.94 and 52.53 % distributing in the range of 4 -100 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.
