- Conclusions:
- 26 % of the particles have a diameter < 125 µm, 13 % < 71µm.
As the substance is highly water soluble (>100g/l), particles inhaled are quickly solved. - Executive summary:
26 % of the particles have a diameter < 125 µm, 13 % < 71µm.
As the substance is highly water soluble (>100g/l), particles inhaled are quickly solved.

Description of key information
26 % of the particles have a diameter < 125 µm, 13 % < 71µm.
Additional information
According to company data of AlzChem (2018) 26 % of the particles of Guanidine Nitrate have a diameter < 125 µm, 13 % < 71µm. As the substance is highly water soluble (>100g/l), particles inhaled are quickly solved.
