Administrative data

acute toxicity: inhalation
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because exposure of humans via inhalation is not likely taking into account the vapour pressure of the substance and/or the possibility of exposure to aerosols, particles or droplets of an inhalable size
Justification for type of information:
Due to the physicochemical data, it can be seen that the melting point is significantly high at 278.2°C, therefore the possibility of the substance becoming a vapour (under normal conditions; 20°C and 101.3 kPa) is unlikely, coupled with the large particle size (majority of the test substance (50%) was 203µm in diameter) it can be stated that the exposure of the substance via the inhalation route is unlikely.
