Test animals
- Species:
- rat
- Strain:
- Sprague-Dawley
- Sex:
- female
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Source: Charles River Laboratories, Germany
- Age at study initiation: One 10-week-old female was used in the sighting study. Four 11-week-old females were used in the main study.
- Weight at study initiation: One female weighing 200 g was used in the sighting study. Four females with the average body weight of 207 g were used in the main study.
- Fasting period before study: The animals will be starved for 18 hours prior to the administration of the test item.
- Housing: The rats will be kept in plastic cages with a wire bar lids and the following dimensions: (length x width x height) 58 x 37 x 21 cm. UV-sterilized wood shavings will be used as bedding.
- Diet (e.g. ad libitum): standard granulated fodder “Murigran", ad libitum
- Water (e.g. ad libitum): tap water, ad libitum
- Acclimation period: At least 5 days
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 20-23 °C
- Humidity (%): 40 – 70%
- Air changes (per hr): 12 hours light – 12 hours dark
- Photoperiod (hrs dark / hrs light): about 16 times/hour
Administration / exposure
- Route of administration:
- other: oral: The test item at a single dose will be given to the stomach of the animal with the aid of a ball ended feeding needle affixed to the top of a syringe.
- Vehicle:
- water
- Details on oral exposure:
- MAXIMUM DOSE VOLUME APPLIED: For all tested doses, the test item will be given in the form of an aqueous solution in a constant volume but at different concentrations. The volume of the aqueous solution given once to the animals will be equal to 0.5 mL/100 g b.w.
- Doses:
- 2000 mg/kg bw
- No. of animals per sex per dose:
- 5 females per dose
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: The evaluation of a general condition of animals, i.e. the observation of all animals for morbidity and mortality will be conducted twice a day or once a day on days off. Detailed clinical observations taking place on the administration day (day 0) will be performed 10, 30 and 60 minutes after the administration and then at hourly intervals – up to the 5th hour after the administration. From the 1st to the 14th day of the observation period detailed clinical observations will be performed once a day. The observations will comprise: changes of the skin, hair, eyes and mucous membranes, respiratory system, circulatory system, autonomic and central nervous system, somatic activity and behavior.
Body weight of the animals will be determined individually for each animal directly before the administration of the test item (day 0) and then on the 7th and the 14th day.
- Necropsy of survivors performed: yes.
All rats which die spontaneously during the experiment will be subjected to a gross necropsy. The rats which survive the experiment will be killed after a 14-day observation period by the intraperitoneal administration of morbital at a dose of 200 mg/kg b.w. and subjected to a post mortem examination. A detailed gross examination of the external body surfaces, all apertures, cranial, thoracic and abdominal cavity with their content will be performed at necropsy.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The oral LD50 value was determined to be greater than 2000 mg/kg bw.
- Executive summary:
The acute oral toxicity study – fixed dose procedure will be conducted in compliance with the OECD Guideline for the Testing of Chemicals No 420 (2001): “Acute oral toxicity – fixed dose procedure” and EU Method B.1.BIS.: “Acute oral toxicity – fixed dose procedure”.
A group of five Sprague-Dawley female rats was exposed orally to a dose level of 2000 mg/kg bw. All animals survived the period of the experiment.
The oral LD50 value was determined to be greater than 2000 mg/kg bw.
