An assessment of acute dermal toxicity with Ammonium sulfate in the rat was performed equivalent to OECD434 test guideline. Ammonium sulfate was administered to the skin surface of the clipped backs of 3 male and 3 female Wistar rats at 2000 mg/kg bw. Careful observations of animals, including body weight changes, mortality figures, gross lesion and behavioural and clinical abnormality, were performed for 14 days. All animals were subjected to necropsy. No mortality occured. Based on the results of the study, the dermal LD50 was >2000 mg/kg body weight. Based on these results, Ammonium sulfate does not have to be classified and has no obligatory labelling requirement for acute dermal toxicity according to Regulation (EC) No 1272/2008 on classification, labelling and packaging of items and mixtures (including all amendments).
