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:
Vapour pressure of test substance is between 4.8 x 10^-5 and 2.7 x 10^-4 Pa. at 20°C (293K) (see section 4.6). Since the vapour pressure was below 0.1 Pa at 20 °C, according to REACH guidance on information requirements and chemical safety assessment (Chapter R. 7a: Endpoint specific guidance) and according to the Chinese Guidance for New Chemical Substance Notification and Registration, X-19555 can be excluded from acute inhalation testing.
