Description of key information
MMAD: 73.3 - 79.0 µm (mean MMAD 76.2 µm) (CIPAC MT187)
Additional information
The particle size distribution of the test item was determined by laser diffraction according to CIPAC method MT187.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
