Several acute oral studies and a dermal toxicity study are available for 1,4-dihydroxyanthraquinone. No study is available for acute inhalation toxicity. This does not need to be conducted according REACH Annex VII column 2 because valid studies for acute oral and dermal toxicity are on hand.
In 3 valid acute oral toxicity studies a LD50 > 5000 mg/kg bw was found. None of the animals died at a single oral dose of 5000 mg/kg bw. In the acute dermal toxicity study the highest applied dose was 2500 mg/kg bw. None of the animals died after application of 2500 mg 1,4-dhihydroxyanthraquinone.
According to CLP classification criteria (Regulation (EC) No 1272/2008) a classification is therefore not justified.
