Additional information
Acute oral toxicity:
In an acute oral toxicity study, groups of fasted young Wistar rats (5/sex) were given a single oral dose of the test substance at doses of 464, 681, 1000 and 1470 mg/kg. Animals were observed for 14 days. All animals died in the highest dosing group. At the lowest dosing group two female was found dead after 24 hours. At 1000 mg/kg three males and three females were found dead after 24 hours. At 681 mg/kg two male and three females were found dead after 24 hours. In all dosing groups dyspnoea, apathy, abnormal body position, staggering, tremor, muscle-twitching, spasms, trismus, ruffled fur, erythema, cyanosis, salivation, bad general condition was observed. The animals which had died during the course of the study showed the following findings at necropsy: heart with acute dilatation at the right side and acute venous hyperemia; Liver with yellow broadened peripheral lobules; atonic intestines with strong mucosal erythema, diarrhoeic contents; atonic stomach with white gastric mucous membrane. The animals which survived until the end of the study showed no abnormalities at necropsy. Based on the results of this study an LD50 of 720.0 mg/kg bw was determined (1978, reliability score: 2).
Acute inhalation toxicity:
In an acute inhalation toxicity study (comparable to OECD guideline 403) 20 Sprague-Dawley rats/dose (10/sex) were exposed head and nose only by the inhalation route to aerosols of the test substance in air for 4 hours at a saturated air concentration of 5.5 mg/L. Animals were then observed for 14 days. No mortality was observed within the 14 day observation period. Reddish secretion from eyes and nose, intermittent respiration, paddling movements and ruffled agglutinated fur was observed. No gross pathological findings were noted. The LD50 was > 5.5 mg/l with the test substance (1978, relability score: 2).
In an inhalation hazard test, 12 young adult rats per sex were exposed for 7 hours with the test substance. No mortalities observed, accelerated respiration was observed (1978, reliability score: 2).
Acute dermal toxicity:
In an acute dermal toxicity study equivalent to OECD guideline 402, groups of young adult Wistar rats (5/sex) were dermally exposed to the unchanged test substance at concentration of 1000, 1470, 2000 and 2610 mg/kg bw for 24 hours. Animals were then observed for 14 days.
At 2610 mg/kg and 2000 mg/kg 4 animals died. At 1470 mg/kg one animal died, in the low dose no animal died. Based on these findings an LD50 of ca. 2800 mg/kg bw was determined. In all dosing groups dyspnoe, apathy, excitation, aggressivness, staggering, tremor, twitch, spasmic gait, convulsions, deep yellow urine, piloerection, lacrimation, clotted eyes, vocalisation of pain, poor general state was observed. Necroses at all dose levels. Animals that died in the course of the study: a) Heart: acute dilatation and acute venous hyperemia; b) Liver with slightly pale peripheral lobules; c) Kidney: grey-brown light-coloured kidneys (nephron necrosis). Animals that were sacrificed after the end of the study: no abnormalities detected. Based on these findings an LD50 of ca. 2800 mg/kg bw was determined (1978, reliability score: 2).
Justification for classification or non-classification
Based on the results of the acute toxicity testing, the test item is classified as harmful if swallowed cat. 4 (H302) according to Regulation (EC) No 1272/2008 (CLP).
