Administrative data

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
Justification for type of information:
In accordance with Column 2 of REACH, Annex VIII, information requirement 8.5.2 (acute toxicity by inhalation) testing is not appropriate as exposure of humans via inhalation is unlikely taking account of the operating conditions applied to substance manufacture and use and the risk manamegement measures that are applied. Furthermore, particle size distribution data indicates that the test material particles are too large to enter the thoracic region of the airways (D10 = 23.64 µm; D50 = 50.11 µm, D90 = 90.01 µm), and are not respirable, and are therefore not available to the airway to cause a toxic effect.
