Description of key information
Acute toxicity - oral: A K1 acute oral toxicity test was performed in male and female Sprague Dawley rats according to a guideline similar to OECD Guideline 401 (Mallory VT, 1983).
Acute toxicity - inhalation: An acute inhalation study does not need to be conducted as the substance is classified as corrosive to the skin (according to REACH, Annex VIII section 8.5, column 2). In addition, acute oral and acute dermal toxicity studies with the test substance are available.
Acute toxicity - dermal: A K1 acute dermal toxicity test was performed in male and female New Zealand White rabbits according to a guideline similar to OECD Guideline 402 (Mallory VT, 1983).

Additional information
Acute toxicity: oral
Mallory VT (1983) investigated the acute oral toxicity via gavage of 400, 630, 1000, 1250 and 1600 mg/kg bw of the test substance in male/female Sprague-Dawley rats (5 animals per sex and per dose) (K1, key study). At 400 mg/kg, 1 male died after day 1; at 630 mg/kg, no mortality was observed; at 1000 mg/kg, 1 male and 2 females died after 1 day, 1 female died after 2 days; at 1250 mg/kg, 2 males died after 1 day, 1 male after 2 days and 1 male after 11 days; 5 females died after 1 day; at 1600 mg/kg, 3 males died after 1 day and 1 male died after 5 days, 5 females died after 1 day. The calculated acute oral LD50 for male and female rats treated with the test substance was determined to be 961 mg/kg with confidence limits of 746 to 1239 mg/kg. Clinical signs observed included decreased body tone and activity, poor grooming, piloerection, salivation, lacrimation, abnormal gait and stance, cyanosis, hypersensitivity, body drop, semi-prostration, diarrhea, dyspnea and prostration. Necropsy of the animals dying on study revealed stomach and intestines fluid-filled and hemorrhagic. The lungs were congested and edematous. Discolored testes and spleen, pancreas, ulcers of the stomach, hydrothorax and hemorrhages of testicular connective tissue were also observed. Terminal necropsy revealed no visible lesions in any of the remaining animals.
Acute toxicity: inhalation
No reliable studies were available for the inhalation route. An acute inhalation study does not need to be conducted as the substance is classified as corrosive to the skin (Regulation (EC) No 1907/2006, Annex VIII section 8.5). In addition, an acute oral and acute dermal toxicity studies are available.
Acute toxicity: dermal
Mallory VT (1983) investigated the acute dermal toxicity of the test substance BAEE in New Zealand White male/female rabbits (2 animals per sex and per dose) after 24 hours of exposure to either 2500, 3200, 4000, 5000, 6300 or 8000 mg/kg bw (K1, key study). After 14 days of observation, the calculated dermal LD50 for BAEE was 3550 mg/kg with 95% confidence limits of 2530 to 4980 mg/kg. None of the rabbits died at 2500 mg/kg, two of four rabbits died at 3200 mg/kg, four of four died at 4000 mg/kg, two of four at 5000 mg/kg and four of four died at the 6300 and 8000 mg/kg dose levels. Clinical signs observed included: vocalizations, necrosis, decreased activity, decreased body tone, bleeding from the anal and genital areas, body drop, abnormal stance, abnormal gait, semiprostration, poor grooming, erythema and edema of the application sites, prostration, cyanosis and abnormal head position. Necropsy of the animals dying on the study revealed dark discolorations and hemorrhages at the application sites, pale kidneys, dark red fluid-filled bladders and pale livers with multiple small irregular yellow nodules, hemorrhages in the cortex of both kidneys, fluid-filled intestines and erosions in the stomach mucosa. Fluid in the thoracic cavity, discolored adrenals, distended bladders, congested lungs and distended fluid-filled intestines were also observed. Terminal necropsy revealed hemorrhages of the muscle layers under the application sites, fluid in the abdominal cavity, liver adhered to abdominal walls, kidneys pitted with surface hemorrhages and small areas of necrosis on the skin sites.
Justification for classification or non-classification
Based on the results of the acute oral toxicity study and according to the criteria laid down in the CLP Regulation, the test substance should be classified as an acute oral toxicant category 4 (H302).
Based on the available data and according to the criteria laid down in the CLP Regulation, the test substance should not be classified for acute dermal toxicity.
No data were available to decide on the classification for the inhalation route.
