The acute toxicity of p-DIPB to rats in oral gavage test was performed. No compound-related effects were observed at gross pathology examination of the high-dose group of animals.
The compound was considered to be slightly toxic following oral administration. The LD50 value was greater than 3200 mg/kg body weight.
Acute toxicity – inhalation
Inhalation is not considered to be a relevant route of potential human exposure
Acute toxicity – dermal
The acute toxicity to guinea pig in dermal test was performed. At most, test item is only slightly toxic by the dermal route.
There was no evidence of percutaneous absorption. LD50 value was determined to be greater than 20 mL/kg bw (= ca. 20000 mg/kg bw/d).
Justification for classification or non-classification
Based on the available data, test item is not classified for acute toxicity according to EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No 1272/2008.
