Additional information
Acute toxicity: via oral route
The available key study (Nitka, 1997) was conducted according to the EPA OTS 798.1175 test guideline (simillar to OECD 401) and in compliance with GLP (limit test). Five Wistar rats per sex received the undiluted test item by oral gavage at the limit dose of 5000 mg/kg bw. A single male rat died during the 14-day observation period and showed depression before death. Slight depression was recorded in a single other male rat, but this resolved by the 24 hour observation period. All other male rats appeared normal. Slight depression was noted in 3/5 females, which resolved within 24 h post dosing. Red anal and urethral discharges were noted, with peri-anal hair loss, which was resolved in all animals by observation day 13. Body weight gain was as expected in all animals. Based on these results, the oral LD50 was determined to be >5000 mg/kg bw for both male and female rats.
Acute toxicity: via inhalation route
No data available (exposure based waiving).
Acute toxicity: via dermal route
The available key study (Schmid, 2013) was conducted according to the OECD 402 and in compliance with GLP (limit test). The shaved dorsal skin of 5 Wistar rats per sex was exposed to the undiluted test substance at a limit dose of 5000 mg/kg bw for 24 h under semiocclusive conditions. After removal of the test substance, animals were observed for a period of 14 days. No mortality and no clinical signs of toxicity were observed up to the end of the observation period. Signs of slight dermal irritation were noted in females only, including scratches (2/5), desquamation (1/5) and eschar (1/5). The body weight development of all male and female animals was within the expected range. Necropsy revealed no substance-related findings. Based on these results, the dermal LD50 was determined to be >5000 mg/kg bw for both male and female rats.
Justification for selection of acute toxicity – oral endpoint
The key study was selected for assessment.
Justification for selection of acute toxicity – dermal endpoint
The key study was selected for assessment.
Justification for classification or non-classification
The available data on acute toxicity do not meet the classification criteria according to Regulation (EC) 1272/2008 or Directive 67/548/EEC, and are therefore conclusive but not sufficient for classification.
