Description of key information

The MMAD (Mass Median Aerodynamic Diameter < 100μm) has a value of 78.22μm as spherical particles. The mass fraction < 100µm was 0.11 % of the total sample.

Additional information

According to OECD guideline 110, the particle size distribution of Hydrochloric acid, reaction products with aniline and nitrobenzene, sulfonated, sodium salts was determined by scanning eletron microscopy method for the sieved fraction (<100 µm, 0.11 % of total sample) and presented on the basis of calculated mass fractions. The median diameter was 78.22 µm with the main fraction of 74 % distribution in the range of 10 - 100 µm; and hence the tested substance with sieved size smaller than 100 µm are mainly dominated by inhalable fraction as defined in EN 481.
