- Photoperiod (hrs dark / hrs light): 12/12
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- corn oil
- Remarks:
- Corn oil Ph.Eur
- Details on oral exposure:
- VEHICLE
- Concentration in vehicle: 40g/100ml
- Amount of vehicle (if gavage): 5ml/kg bw
- Justification for choice of vehicle: Good homogeneity in corn oil Ph.Eur.
DOSAGE PREPARATION (if unusual):
The test item preparation was produced for each administration group shortly before administration by stirring with a high speed homogenizer (Ultra-Turrax) and a magnetic stirrer. Additionally, the homogeneity of the test item preparation during administration was ensured by stirring with a magnetic stirrer.
CLASS METHOD (if applicable)
- Rationale for the selection of the starting dose: - Doses:
- 2000 mg/kg
- No. of animals per sex per dose:
- 6 (2 groups of three females each)
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Body weight determination: Individual body weights shortly before administration (day 0), weekly thereafter and on the last day of observation.
- Clinical observations: Clinical signs for each animal were recorded several times on the day of administration and at least once during each workday thereafter.
- Mortality: A check for any dead or moribund animals was made at least once each workday; these records are archived by Bioassay.
- Pathology: Necropsy with gross-pathology examination was performed on the last day of the observation period after sacrifice by CO2-inhalation in a chamber with gradually increasing concentrations.

- Gross pathology:
- There were no macroscopic pathological findings in the animals sacrificed at the end of the observation period (6 females).
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the conditions of this study the median lethal dose of the test article after oral administration was found to be greater than 2000 mg/kg bw in rats.
- Executive summary:
In a GLP-compliant acute oral toxicity study performed according to the Acute Toxic Class method (OECD 423), a dose of 2000 mg/kg bw of the test item (preparation in corn oil Ph.Eur.) was administered by gavage to two test groups of three fasted female Wistar rats each. No mortalities occurred. Impaired general state and piloerection in all animals occurred within the first 3 days after administration. The body weight of the animals in both test groups increased within the normal range throughout the study period with two exceptions in the first test group. In these two animals the body weights were within the normal range during the first week, but stagnated during the second week. This effect is observed at times in the rat strain used, because in the required age range the female animals have already reached the phase of slow growth. There were no macroscopic pathological findings in the animals sacrificed at the end of the observation period (6 females). The acute oral LD50 was calculated to be > 2000 mg/kg bw.
