- Weight at study initiation: Males 154 - 212 g Females 127 - 131 g
- Fasting period before study: 16 h before treatment
- Housing: individually, Macrolon cages, type II, Bedding: Animal bedding chips, supplied by Jelu-Werk, J. Ehrler, Industriemehle, D-7092 Rosenberg/Württ.
- Diet (e.g. ad libitum): Standard diet ad libitum ssniff R, "Special diet for rats", supplied by ssniff Spezialfutter GmbH, D-4770 Soest
- Water (e.g. ad libitum): Water was provided ad libitum in drinking water quality from the Stadtwerke Bielefeld (Municipal Works), using an automatic drinking water system with drinking nipples.
- Acclimation period: The animals were kept at least 5 days under test conditions before administration of the test substance. Veterinary supervision of the animals was done before start of study.

- Details on oral exposure:
- VEHICLE
- Concentration in vehicle: 237 mg/mL
- Amount of vehicle (if gavage): 21.5 mL/kg
MAXIMUM DOSE VOLUME APPLIED: 21.5 mL/kg
- Doses:
- 5110 mg/kg b.w.
- No. of animals per sex per dose:
- 5
- Control animals:
- not specified
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: The body weights were recorded at the beginning and also 7 and 14 days after administration. The animals were continuously observed for the first 4 to 6 hours after administration and then once daily. The nature of the toxicity as well as the onset, the intensity, and the duration of the signs were recorded. Mortality was checked twice daily (a.m. and p.m.), on Saturdays, Sundays, and on national holidays only once.
- Necropsy of survivors performed: yes
- Other examinations performed: clinical signs, body weight, other: Mortality - Statistics:
- The LD 50 values were above a dose of 5110 mg/kg in male and female rats, thus no further statistics were performed.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In a study conducted according to OECD guideline 401 (1987) the LD 50 values were above a dose of 5110 mg/kg in male and female rats. Thus, the test item does not need to be classified according Regulation (EC) No 1272/2008 (CLP) and the Globally Harmonized System for Classification and Labelling of Chemicals (GHS) with respect to acute oral toxicity.
