One male was found dead on day 7. On day 1 in the morning, all animals had decreased locomotion. One female and two males appeared dehydrated therefore all animals were given a water bottle. On day 1, in the afternoon, one female had decreased locomotion, all other animals appeared normal. There were no gross abnormalities in any of the surviving animals. One male was found to have both kidneys dilated, the liver was pale pink, stomach and intestines were distended with gas. Based on the results in this study, the acute oral LD50 for the substance in male and female rats was determined to be >2000 mg/kg bw and the substance does not have to be classified for acute toxicity by the oral route according to Regulation (EC) No. 1272/2008.

Additional information
Acute oral:
In this study performed according to OECD TG 401 guideline and GLP principles, 10 rats (5 males and 5 females) were administered with the substance at a dose level of 2000 mg/kg bw. One male was found dead on day 7. On day 1 in the morning, all animals had decreased locomotion. One female and two males appeared dehydrated therefore all animals were given a water bottle. On day 1, in the afternoon, one female had decreased locomotion, all other animals appeared normal. There were no gross abnormalities in any of the surviving animals. One male was found to have both kidneys dilated, the liver was pale pink, stomach and intestines were distended with gas. Based on the results in this study, the acute oral LD50 for the substance in male and female rats was determined to be >2000 mg/kg bw.
Acute inhalation:
Acute inhalation is predicted based on the acute oral toxicity in accordance with the CLP guidance document (2015, page 255). The acute inhalation is predicted to be 5200 mg/m3 and the saturated vapour pressure is 90 mg/m3. This means that the acute inhalation concentration cannot be reached and therefore no acute inhalation is anticipated.
Acute dermal:
In this study performed equivalent to OECD TG 402 guideline, 6 rabbits (3 males and 3 females) were administered to the substance at a dose level of 2000 mg/kg bw. No deaths occurred and no unusual behavioral signs were noted. There were no signs of dermal irritation and no abnormalities were noted at necropsy. The acute dermal LD50 for the substance in male and female rats was determined to be >2000 mg/kg bw.
Justification for classification or non-classification
Based on the results, the substance does not have to be classified for acute toxicity by the oral, inhalation and dermal route according to Regulation (EC) No. 1272/2008 and its amendments.
