Description of key information
Both studies were performed in 1985. The reliability of these reports is Klimisch 1 as these studies were performed under GLP.
The calculated acute oral LD50 for male and female rats was determined to be 1569 mg/kg with 95% confidence limits of 1243 to 1980 mg/kg The calculated acute oral LD50 in males was determined to be 1960 mg/kg with 95% confidence limits of 1376 to 2792 mg/kg. The calculated acute oral LD50 in females was determined to be 1231 mg/kg with 95% confidence limits of 860 to 1761 mg/kg.
The acute dermal LD 50 for rabbits was determined to be greater than 8.0 g/kg.
Based upon the observations made in the study, the estimated LD50 of the test material was determined to be greater than 8.0 g/kg. Therefore, the test substance is considered not to be classified according to CLP regulation .

- Executive summary:
In the dose-range finding study, four fasted animals per dose level, two per sex, were administered the test article at 1000 / 3000 / 6300 and 10000 mg/kg, orally, by gavage.
Signs observed were decreased, activity, ptosis, salivation, decreased muscle tone, dyspnea, abnormal gait, abnormal stance, ataxia, discoloration around mouth and anus and prostration. None of the rats died at 1000 mg/kg. All of the rats died at the 3000 / 6300 and 10000 mg/kg dose levels.
Four groups of ten rats (five males and five females) were fatsed for eighteen hours and administered the test item at a dose levels of 1000 / 1600 / 2000 and 2500 mg/kg by oral gavage. Signs observed included decreased activity, dyspnea, decreased muscle tone, salivation, ptosis, nasal discharge, chromodacryorrhea, diarrhea, abnormal stance, abnormal gait, lacrimation and prostration. Two of ten rats died at 1000 mg/kg, five died at 1600 mg/kg, seven died at 2000 mg/kg and eight died at 2500 mg/kg. Necropsy of the animals dying on study revealed fluid-filled stomachs and intestines with multiple lesions in the stomach. No visible lesions were observed at terminal necropsy.
Based upon the results of the acute oral toxicity study in rats, the calculated acute oral LD50 for male and female rats treated with the test item, was determined to be 1569 mg/kg with 95% confidence limits of 1243 to 1980 mg/kg. The calculated acute oral LD50 in males was determined to be 1960 mg/kg with 95% confidence limits of 1376 to 2792 mg/kg. The calculated acute oral LD50 in females was determined to be 1231 mg/kg with 95% confidence limits of 860 to 1761 mg/kg.
