Six rats had dried or wet yellow staining around the mouth. Wet and/or drid brown urogenital staining was noted for two rats. There were single occurences of hypoactivity and clear wet matting around the mouth. One rat had clear ocular discharge at the 3 and 4 hour post dose observation. There were no other clinical findings. All animals appeared normal on days 13 and 14.
- Body weight:

Nine rabbits were hypersensitive to site manipulation during the dirst week of the study. Eschar and subsequent exfoliation were present on six sites by day 7. Fissuring was noted sporadically during the first week of the study for six sites. All sites had very slight to slight erythema and/or oedema and desquamation at study termination (day 14).

Additional information
Justification for classification or non-classification
In accordance with regulation EC 1272/2008 (CLP), the substance is not classified for acute toxicity based on the acute oral LD50 of >5000 mg/kg bw and the acute dermal LD50 >2000 mg/kg bw.
