Acute Toxicity: inhalation
Administrative data
- Endpoint:
- acute toxicity: inhalation
- Data waiving:
- study scientifically not necessary / other information available
- 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

- Reason / purpose for cross-reference:
- data waiving: supporting information
Reference
- Endpoint:
- particle size distribution (granulometry)

- Conclusions:
- Median particle size of D50 = 17.5 µm
- Executive summary:
Particle size distribution of the test substance was determined by laser diffraction measurement, according to the OECD Guideline 110 (1981) and ISO 13320 (2009).
The substance has a median particle size of D50 = 17.5 µm.
- Reason / purpose for cross-reference:
- data waiving: supporting information
Reference
- Endpoint:
- vapour pressure
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the melting point is above 300°C
