Justification for type of information:
In accordance with Column 2 of REACH Annex VIII, in addition to the oral route (8.5.1), for substances other than gases, the information mentioned under 8.5.2 (acute toxicity by inhalation) and 8.5.3 (acute toxicity by the dermal route) shall be provided for at least one other route. The choice for the second route will depend on the nature of the substance and the likely route of human exposure. In the present case, inhalation exposure will be lower than dermal exposure because the registered substance has a low vapour pressure (7.5 x 10-6 Pa at 25°C) which indicate an absence of volatility and therefore the potential to generate vapor is negligible. Nonetheless, considering the use of the substance, exposure to mist can occur. However, based on the absence of acute toxicity by oral route, no mortality is anticipated during the exposure to mist. Moreover, no respiratory irritation is expected that could increase the absorption of the substance by inhalation. Hence, dermal exposure is the most likely route of exposure during the manufacture and the use of the substance although skin absorption is expected to be limited (Log Kow = 9.5).
