Animals in both dose groups exhibited clinical signs of toxicity and effects on mortality were observed.
Under the conditions of the study the acute oral LD50 of the test material was determined to be 2000 mg/kg bw.

Additional information

The acute oral toxicity of the test material was investigated in a study which was conducted in accordance with the standardised guideline OECD 410, under GLP conditions.
During the study, two doses were tested (single dose of 1000 and 2000 mg/kg bw/d) with a 14 -day observation period.
Animals in both dose groups exhibited clinical signs of toxicity and effects on mortality were observed.
Under the conditions of the study the acute oral LD50 of the test material was determined to be 2000 mg/kg bw.
Anonymous (1976) Read-across data (mixture DOTE: MOTE. 75:25) (CAS No 15571-58-1 and CAS 27107-89-7)
The acute oral toxicity of the test material was determined in a study which was conducted according to a method that is comparable to the standardised guideline OECD 401.
During the study, groups of 5 male and 5 female rats were fasted overnight and administered a single oral dose of the test material at dose levels of 300, 600, 1000, 1500, 3000, 6000, and 10000 mg/kg bw. Animals were observed for 14 days. Animals that died were sacrificed and necropsied. Surviving animals were sacrificed and necropsied at the end of the observation period.
Under the conditions of the study none of the rats dosed at levels up to and including 1500 mg/kg bw died. Four males and two females dosed at 3000 mg/kg bw died, five males and four females dosed at 6000 mg/kg bw died, and all animals dosed at 10000 mg/kg bw died. Signs and symptoms of toxicity at dose levels ≥ 3000 mg/kg bw included transient hypoventilation, roughening of the coat, ataxia, ventricumbency, muscular hypotonia, inhibition to pain, and piloerection. Gross changes in animals that died during the study included pulmonary oedema, gastroenteritis with dilated stomach and slight atrophied thymus and spleen. No gross changes were observed in animals that survived the study/observation period.
Under the conditions of this study the LD50 of the test material was 3050 mg/kg bw.
Anonymous (1982) Read-across data (mixture DOTE: MOTE. 53:22) (CAS No 15571-58-1 and CAS 27107-89-7)
The acute oral toxicity of the test material was determined in a study which was conducted according to a method that is comparable to the standardised guideline OECD 401.
During the study, groups of 5 male and 5 female rats were fasted overnight and administered a single oral dose of the test material at dose levels of 1000, 2500, and 5000 mg/kg bw. Animals were observed for 14 days. Body weights were recorded on days 1 (prior to dosing), 7, 14, and at death. Animals that died were sacrificed and necropsied. Surviving animals were sacrificed and necropsied at the end of the observation period.
Under the conditions of the study none of the rats dosed at 1000 mg/kg bw died. At 2500 mg/kg bw 1 male and 3 females died, and at the top dose level of 5000 mg/kg bw all the animals died. Signs and symptoms of toxicity included sedation, dyspnoea, ruffled fur, diarrhea, exophthalmus, anc curved body position.
Under the conditions of the study the acute oral LD50 of the test material was determined to be 2775 mg/kg bw.
Justification for classification or non-classification
In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No 1272/2008, the substance does not require classification with respect to acute oral toxicity.
