Additional information
Based on the available data from acute oral toxicity study, Anthraquinone is non toxic if swallowed (LD50oral,rat is>2000 mg/kg bw).
Description of study on acute toxicity of Anthraquinone via inhalation route reported in IUCLID (February 19, 2000) was very brief and information was not sufficient for the assessment of human health. The inhalation study conducted by Industrial BIO-TEST Laboratories, Inc. stated the LC50(4h)>0.244 mg/l. The concentration of 0.244 mg/l air was maximum attainable concentration the animals were exposed to and there were no untoward reactions during exposure or the 14-day observation period which followed. Therefore Anthraquinone is regarded as non toxic if inhaled.
The results from acute dermal toxicity test indicated Anthraquinone as being a non toxic in contact with the skin (LD50dermal, rat is >3000 mg/kg bw).Justification for classification or non-classification
Based on the test results and according to the EC criteria for classification and labelling requirements for dangerous substances and mixtures the test substance Anthraquinone did not fall into any of quoted categories of toxicity and has no obligatory labelling requirement in this respect.
