Description of key information

Fine powder, with a potential for inhalation exposure (more than 80% of particles having a diameter < 10 µm may reach the thoracic fraction), however this is limited by the tendency to aggregate into particles of MMD of ca 125 µm.
Potential for dust explosion should also be considered.

Additional information

A GLP study, conducted both with sieve and image analysis, provided non-consistent results, but these can be explained by the tendency of the substance 99422018 to aggregate.
