Description of key information
With regard to inhalation potential, ca. 0,96 % can be inhaled (< 100 micrometer). The alveoli relevant thoracic fraction part < 0,01 mm of the particle distribution is < 0.06 % of total mass of the substance and therefore not relevant.
The mass median diameter is 0.58 mm.
D10 is 0.23 mm, D50 is 0.49 mm, D90 is 0.87 mm.
The geometric standard deviation for D10 and D90 is 1.96 and 1.93.
