Additional information
Acute toxicity: oral
The test substance was tested based on internal BASF protocol on Sprague-Dawley rats (males / females), which is similar to OECD TG 401 (BASF, 1976). The rats were orally administrated (gavage) at doses 316, 464, 462, 681, 1210, 1470, 1780 and 2150 µL/kg. The animals were observed for 14 days. Clinical signs, body weights and necropsy was performed. No deaths were observed after 14 days at doses of 316 and 464 µL/kg. At the dose of 562 µL/kg, 4/10 deaths were observed after 14 days. At the dose of 681 µL/kg, 8/10 deaths were observed after 14 days. While at all higher dose levels, 10/10 deaths were observed after 14 days. The following clinical signs were observed: dyspnea, apathy, abdominal position, staggering, partly atony, twitching, trembling, partly biting convulsions, partly clonic convulsions, cyanosis, partly lacrimation, poor general state. No abnormal effects were observed in body weight gain. Gross pathology revealed acute dilatation in the heart and acute congestive hyperemia. The LD50 was determined to be 472 mg/kg bw. Additionally, a supporting study on rats exposed to the test substance via the oral route (Carpenter et al., 1974) revealed an LD50 of 1230 mg/kg bw (the original value was reported as 1540 µL/kg).
Acute toxicity: Inhalation
In a study similar to OECD TG 403 (BASF, 1980), acute toxicity via inhalation was tested based on a dynamic inhalation system at which the whole-body was exposed with an analytical and nominal determination of concentration. Ten Sprague Dawley rats (male / female) were exposed to vapour with the test item for 4 hours. The analytical concentrations determined at 0.60, 1.54, 1.86, 2.64, 5.95 mg/L while the nominal concentrations used were 1.60, 4.02, 5.35, 8.03, 9.64 mg/L. After the exposure period, the surviving animals were observed for 14 days. The body weight of the animals was checked before the beginning of the test, after 7 days and at the end of the observation period. The absolute body weight gain and the relative body weight gain (difference in weight between the initial weight of the animals and the following weights) were determined from the values and presented graphically. Clinical findings and lethality were recorded daily. At the end of the 14-day observation period, the animals were sacrificed with CO2 and were subjected to a gross-pathological examination like all other animals which had died before. At the dose of 0.6 (1.6) mg/L and 1.54 (4.02) mg/L: no deaths were observed. At the concentration of 1.86 (5.35) mg/L, 5/10 male and 5/10 females dead animals were found. At the dose of 2.64 (8.03) mg/L: 7/10 male / 8/10 females dead animals were found. At the dose of 9.64 (5.95) mg/L all animals died. In all dose groups the following clinical signs were observed: watery eye/nasal secretion (partly reddish), eyelid closure, salivation, intermittent breathing, crouching position, abdominal position, twitching, trembling resp. clonic convulsions, apathy, staggering gait, ruffled fur. The gross pathology revealed acute dilatation of the atrium in heart; acute congestive hyperemia; intense blood filling with slight edematization in the lung; broadened liver, loam-brown liver lobe periphery, partly liver with lateral corrugation in the animals that died. The animals that were sacrificed, nothing abnormal was detected. All symptoms were weaker in the lower dose groups. The LC50 was determined to be 2.1 mg/L air (2100 mg / m3). Further, the test substance was tested on male/female rats which were exposed on the test substance using vapours for 3 and 10 minutes (BASF, 1976). For saturation, air was passed through an approximately 5 cm high layer of the test substance. 12 animals per sex and per dose were used when the exposure period was 3 minutes and 6 animals per sex and per dose when the exposure period was 10 minutes. When the animals were exposed for 3 minutes, no deaths were observed. When the animals were exposed for 10 minutes, 6/6 animals were found dead. In gross pathology examinations, the following effects were observed: acute heart dilatation (both-sided); acute congestive hyperemia; lung: partly infarctoid blood filling with slight edematization. Additionally, a supporting study on rats exposed to the test substance via inhalation (Carpenter et al., 1974) resulted in 6/6 deaths after 20 minutes of exposure to the test substance in a room saturated or enriched at room temperature. During the same study, after 4 h exposure to a concentration of 1000 ppm (4.6 mg/L), 2 out of 6 animals were found dead.
Acute toxicity: dermal
In a study on rabbits exposed to the test substance via the dermal route (Carpenter et al., 1974) the LD50 was determined at 460 mg/kg bw. The information with regard to the lethal dose was reported as LD50 = 570 µL/kg in the same. The description of materials and methods is brief, however the reported LD50 value for the acute toxicity via the dermal route, taking into account the available information for acute toxicity via the oral route and inhalation, suffice for classification of the test substance.
Justification for classification or non-classification
Based on an oral LD50 of 472 mg/kg bw, a dermal LD50 of 460 mg/kg bw, and an inhalation LC50 of 2100 mg / m3, the substance is classified as Acute Tox. 4 H302: Harmful if swallowed, Acute Tox. 3 H331: Toxic if inhaled, Acute Tox. 3 H311: Toxic in contact with skin, in accordance with EU Classification, Labeling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008.
