Acute Toxicity: dermal

Administrative data

Endpoint:

acute toxicity: dermal

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the substance does not meet the criteria for classification as acute toxicity or STOT SE by the oral route and, in the absence of an in vivo study by the oral route, no systemic effects after dermal exposure are predicted on the basis of non-testing approaches (e.g. read across, QSAR studies)

Justification for type of information:

According to Commission Regulation (EU) 2016/863 amending Regulation EC No. 1907/2006, acute testing by the dermal route does not need to be conducted if the substance does not meet the criteria for classification as acute toxicity or STOT SE by the oral route, and no systemic effects have been observed in in vivo studies with dermal exposure. The test material displayed an acute oral LD50 > 2000 mg/kg bw in rats, is not classified as STOT SE, and no systemic toxicity or local irritation was observed in a LLNA study in mice. Therefore the substance meets the criteria for waiving the testing requirements for acute dermal toxicity.
