Description of key information

D10, D50 and D90 mean values of 1.3, 6.1 and 12.4 µm respectively.

Additional information

A study was performed to determine the size distribution of particles present in the test substance E99434 according to OECD Guideline 110 under GLP using particle size apparatus based on laser diffraction.

Fine powder, with a potential for inhalation exposure (more than 70% of particles having a diameter < 10 µm may reach the thoracic fraction).

Potential for dust explosion should also be considered.
