Applicant's summary and conclusion
- Interpretation of results:
- not classified

- Executive summary:
An assessment of acute oral toxicity with the test article in female and male Wistar rats was employed using the acute toxic class method. The study was carried out based on OECD 423 and the EC Commission Directive 96/54/EC, Part B.1. The test article was administered by oral gavage to three Wistar rats of each sex at 2000 mg/kg body weight. Animals were subjected to daily observations and weekly determination of body weight. Macroscopic examination was performed after terminal sacrifice. No mortality occurred. Lethargy, uncoordinated movements, hunched posture and/or chromodacryorrhoea were noted among the females between days 1 and 3. Lethargy and uncoordinated movements were noted among the males between days 1 and 2. The mean body weight gain shown by the animals over the study period was considered to be normal. No abnormalities were found at macroscopic post mortem examination of the animals. The oral LD50 values of the test article in Wistar rats was established to exceed 2000 mg/kg body weight.
Based on these results and according to the EC criteria for classification and labelling requirements for dangerous substances and preparations, the test article does not have to be classified and has no obligatory labelling requirement for oral toxicity.
