Amines, N-C12-14-alkyltrimethylenedi-

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

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:

JUSTIFICATION FOR DATA WAIVING
There is no study on inhalation toxicity available for N-C12,14 alkyl-1,3-diaminopropane (CAS 90640-43-0, also referred to as C12-14-diamine).
REACH stipulates that testing by the inhalation route is appropriate if exposure of humans via inhalation is 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. REACH guidance R.7.a, chapter. 7.4 Acute toxicity, indicates that in principle no inhalation studies are needed when vp < 0.1 Pa at 20°C or particle size > 100 µm. C12-14-diamine is a fluid/paste with a vapour pressure of 0.0015 Pa at 20°C. Also the use of this substance will not result in aerosols, particles or droplets of an inhalable size, so exposure to humans via the inhalation route will be unlikely to occur, and no acute inhalation test was performed.
