Justification for type of information:

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 [exposure considerations]. Furthermore, according to Annex VIII, Section 8.5, Column 2, of Regulation EC No. 1907/2006, a toxicity study, in addition to the acute oral toxicity study, under 8.5.2 to 8.5.3 shall be provided for at least one other route. Regulation EC No. 863/2016 amends this data requirement, stating that substances that are not toxic via the oral route may be expected with high certainty to be also non-toxic via the dermal route. The risk of acute toxicity by the dermal route has been addressed in light of an acute oral toxicity study with a LD50 > 2000 and no systemic toxicity observed in other in vivo studies. It is determined that testing for acute dermal toxicity is not scientifically indicated. The criteria for satisfaction of Sections 8.5.2 and 8.5.3 are met and the data requirement for an acute toxicity study by a third route, inhalation, is waived.
