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 the substance is classified as corrosive to the skin
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
In addition to the GHS and EU CLP 1272/2008 classification for skin corrosion (Category 1A), inhalation studies have also been waived based on dustiness data. Dustiness data for this substance showed that the respirable fraction (2.30 mg/g) is just 4.3% of the total inhalable fraction (52.94 mg/g) which leaves the majority (95.7%) which is not respired (sneezed or swallowed). These data reflect the particle size data (MMAD 34.9µm) when considering that respirable particles are usually under approximately 10 µm.
