- Frequency of observations and weighing: Daily animal health observations were conducted throughout the study for mortality and signs of illness, injury, or abnormal behavior. Except as noted below, animals were weighed on test days -1, 1, 8, and 15, and were observed for clinical signs at the beginning of fasting, just before dosing (test day 1), once during the first 30 minutes after dosing and 2 more times on the day of dosing, and once each day thereafter. Clinical observations were inadvertently not recorded on test day 5. The daily animal health observations recorded on those days, and the clinical observations collected on the preceding and succeeding days, were sufficient to assess the animals’ conditions.

- Executive summary:
A single dose of the test substance was administered by oral gavage to fasted female rats at a dose of 5000 mg/kg. The five rats were dosed on the same day. All rats were observed for mortality, body weight effects, and clinical signs for 14 days after dosing. The rats were necropsied to detect grossly observable evidence of organ or tissue damage. There were no incidents of mortality, clinical abnormalities, or overall (test day 1-15) body weight loss. No gross lesions were present in the rats at necropsy. Under the conditions of this study, the test substance was not considered acutely toxic via the oral route of exposure in female rats at a dose level of 5000 mg/kg. In the absence of test substance related mortality, an LD50 was not calculated.

The rats were necropsied to detect grossly observable evidence of organ or tissue damage at the end of the 15-day test period.
There were no incidents of mortality and no overall (test day 1-15) body weight losses among any animals. One male exhibited scabbing on the back (inside of the test site) between test days 6-15 and discoloured skin on the back between test days 6-7. Between test days 12-15, a wound on the right shoulder was observed in one male. Epidermal scaling (inside the test site) was noted in one female between test days 6-8. No other clinical abnormalities were observed. There were no instances of oedema or erythema observed. Gross findings were present in 2/5 male animals, which correspond to the clinical observations noted above. One male had a skin ulcer/erosion present on the back at the outer edge of the treated skin area. The other male had a single skin ulcer/erosion present on the right shoulder. No other gross findings were observed. Under the conditions of this study, the dermal LD50 for the test substance was greater than 5000 mg/kg of body weight when applied to the skin of male and female rats for 24 hours.

Justification for classification or non-classification
Based on the oral and dermal LD50 in rats of >5000 mg/kg, no classification is required for acute oral or dermal endpoints according to EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
