Number of animals per group: 5 males, 5 females
Age when treated: males: 8weeks females: 10 weeks
Body weight range when treated: males: 201 - 205 g females: 172 - 182 g
Identification: By unique cage number and corresponding color-coded spots on the tail.
Randomization: Randomly selected at the time of delivery into groups of five.
Acclimatization: One week under laboratory conditions, after health examination. Only animals without any visible signs of illness were used for the study.

Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- water
- Details on oral exposure:
- test article preparation:
The test article was placed into a glass beaker on a tared Mettler PM 460 balance, and the vehicle (bi-distilled water) was added. A weight by volume dilution was prepared. A homogenizer (Ultra-Turrax, Janke & Kunkelr 0-79219 Staufen) was used to ensure homogeneous distribution of the test article in vehicle.
Homogeneity of the test article in the vehicle was maintained during treatment using a magnetic stirrer (Janke & Kunkel, D-79219 Staufen) .
The preparation was made shortly before dosing.
Treatment:
The animals received a single dose of the test article on a mg/kg body weight basis by oral gavage following fasting for approximately 16 hours, but with free access to water. Food was provided again approximately 3 hours after dosing.
Dose/kg body weight: 2000 mg
Application Volume/ kg body weight: 10 ml
Rationale: Oral administration was used as this is one possible route of human exposure during manufacture, handling and use of the test article. - Doses:
- 2000 mg/kg bw
- No. of animals per sex per dose:
- 5 per sex per dose
- Control animals:
- no
- Details on study design:
- test article was administered by single oral gavage to rats, followed by an observation period of 14 days.
observation:
Mortality / Viability: Four times during test day 1 and once daily during days 2 - 15.
Body Weights: On test day 1 (pre-administration), 8 and 15.
Clinical Signs: Each animal was examined for changes in appearance and behaviour four times during day 1 and once daily during days 2 - 15. - Statistics:
- The LOGIT-Model could not be used as no deaths occurred.
Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Remarks on result:
- other: There were no deaths as a result of treatment with the test article. No adverse effect was observed in the clinical sign, body weight and macroscopic findings.
- Mortality:
- There were no deaths as a result of treatment with the test article.
- Clinical signs:
- other: No clinical signs of toxicity were observed during the observation period.
- Gross pathology:
- No macroscopic findings were observed at necropsy.
Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Criteria used for interpretation of results: EU
- Conclusions:
- The mean lethal dose of test article after single oral administration to rats of both sexes, observed over a period of 14 days, could not be estimated, because no mortality occured and the LD50 was found greater than 2000 mg/kg.
- Executive summary:
The test article was administered to a group of 5 male and 5 female rats by oral gavage, at a single dose of 2000 mg test article/kg body weight. A weight by volume dilution was prepared with bi-distilled water as vehicle. There were no deaths as a result of treatment with the test article. No clinical signs of toxicity were observed during the observation period. The body weight of the animals was within the normal range for rats of this strain and age. No macroscopic findings were observed at necropsy.
Therefore, it is concluded that test article is not subject to classification for acute oral toxicity according to CLP (Regulation EC No. 1272/2008).
