Additional information
A study was conducted to determine the skin irritation properties of 2-Bromo-3,3,3-trifluoropropene (Huntingdon Life Sciences, 2012, Study code WAG0010). The study was performed according to OECD test guideline 404 and EC guideline B4, and in compliance with GLP.
Three New Zealand White rabbits received a single occlusive dermal application of the test substance for four hours; animals were observed for four days after exposure. None of the exposed animals displayed any sign of dermal reaction (irritation) to the treatment..
On the basis of these results it was concluded that 2-bromo-3,3,3-trifluoropropene is not irritant to skin.
A study was conducted to determine the eye irritation properties of 2-Bromo-3,3,3-trifluoropropene (Huntingdon Life Sciences, 2012, Study code WAG0011). The study was performed according to OECD test guideline 405 and EC guideline B5, and in compliance with GLP.
Three New Zealand White rabbits received a single ocular application of the test substance; animals were observed for four days after exposure. None of the exposed animals displayed any sign of dermal reaction (irritation) to the treatment..
On the basis of these results it was concluded that 2-bromo-3,3,3-trifluoropropene is not irritant to eyes.
Although no specific study to assess irritation to the respiratory tract was conducted, irritation effects were observed in the respiratory tract of rats in the acute and repeat dose studies by the inhalation route.
In the acute toxicity study (Huntingdon Life Sciences, Report No.02-5449, 2004), clinical signs noted immediately following the exposures of BTP included clear or red nasal discharge. Macroscopically, rats from both exposure levels had red discolorations of the lungs. Fluid was present in the lungs of one male from the higher level exposure of 26,580 ppm. Microscopically, test substance related effects were observed in lungs of rats in the higher level exposure of 26,580 ppm. All of the rats, in this group only, had bronchiolar lesions consisting of desquamated epithelium, bronchiolar/peribronchiolar acute/subacute inflammation.
In the repeated dose study (Huntingdon Life Sciences Report No. WAG0014, 2013) including the range finding studies (Huntingdon Life Sciences Reports No. WAG0013 and WAG0024, 2012), treatment-related, but transient, clinical signs (shallow breathing, piloerection, grinding teeth and hunched posture), related to inhalation of an irritant material, were evident during and after exposure.Histopathological changes related to treatment were seen in the nasal turbinates, larynx and trachea and were related to exposure to an irritant material. Overall, the most marked changes were in the nasal cavity, with less severe changes in the larynx and trachea.Histopathological changes included atrophy/disorganisationand inflammation of the olfactory epithelium, atrophy of the olfactory nerve fibres, inflammatory exudate in the airways, perivascular and peribronchiolar inflammatory infiltrate and bronchiolar epithelial hyperplasia in the lungs, epithelial hyperplasia and sub epithelial inflammation in the larynx and epithelial hyperplasia at the tracheal bifurcation.
Justification for selection of skin irritation / corrosion endpoint:
The study was conducted according to official (EC, OECD, US EPA, JMAFF) test guidelines and in compliance with GLP; the study is considered a reliable source on this basis.
Justification for selection of eye irritation endpoint:
The study was conducted according to official (EC, OECD, US EPA, JMAFF) test guidelines and in compliance with GLP; the study is considered a reliable source on this basis.
Justification for classification or non-classification
In-vivo skin and eye irritation studies each concluded that the substance did not show any irritant properties. The substance therefore does not meet the classification criteria for skin or eye irritation.
The irritation observed in the respiratory tract in the acute and repeated dose studies by the inhalation route are the basis of the classification of BTP as a STOT single exposure 3 (H335: may cause respiratory irritation) under the CLP regulation.
