Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- corn oil
- Details on oral exposure:
- VEHICLE
- Concentration in vehicle: 30 and 200 mg/ml
- Justification for choice of vehicle: The vehicle used in this study was selected from the results of solubility assays. The solubility assay first started at the concentration of 200 mg/mL, and the first choice vehicle was drinking water treated by reverse osmosis. As unsatisfactory solubility of the test item was obtained in this vehicle (i.e. heterogeneous preparation at the concentration of 200 mg/mL was obtained), another vehicle was chosen from the following organic solvents (in order of preference): 0.5% methylcellulose aqueous solution and corn oil. A homogenous suspension was obtained at the concentration of 200 mg/mL in corn oil.
MAXIMUM DOSE VOLUME APPLIED: 10 ml/kg bw
CLASS METHOD (if applicable):
- Rationale for the selection of the starting dose:
Since no relevant toxicity data were available for the estimation of a lethal dose-level and any existing data were taken into account, the starting dose level was 300 mg/kg for ethical reasons. - Doses:
- 300 and 2000 mg/kg bw
- No. of animals per sex per dose:
- 3 per treatment step.
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Clinical observations: frequently during the hours following treatment; then, at least once a day.
- Body weight: just before treatment, then on day of treatment (day 1) and on days 8 and 15.
- Necropsy of survivors performed: yes - Statistics:
- none
Results and discussion
Effect levels
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No unscheduled deaths occurred during the study.
- Clinical signs:
- Piloerection was observed in 3 out of 6 females given 2000 mg/kg bw 4 hours after treatment on day 1 and on day 2.
No clinical signs were observed in other animals. - Body weight:
- A slightly lower body weight gain was noted in one or two females per group (30 g to 37 g vs. 44 g ± 4.2 g in control data base) between day 1 and day 8. A lower body weight gain was also noted in one or two females per group (3 g to 10 g vs. 20 g ± 5.7 g in control data base) between day 8 and day 15.
When considering the day 1 to day 15 period, the body weight change was lower in two females from group 1 treated at the dose-level of 300 mg/kg (40 g and 45 g) and in 4/6 females treated at the dose-level of 2000 mg/kg (between 49 g and 57 g). - Gross pathology:
- No abnormalities were noted.
- Other findings:
- None

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The oral LD50 of the test substance was higher than 2000 mg/kg in rats.
Therefore, the substance is not classified according to Regulation (EC) No. 1272/2008 and its subsequent amendments on classification, labeling and packaging (CLP) of substances and mixtures. - Executive summary:
The substance was tested for acute oral toxicity according to OECD 423 guideline and in compliance with Good Laboratory Practices.
The test item was administered once by gavage to 3 groups of 3 fasted female rats under a dosage-volume of 10 mL/kg bw. The test item was prepared in corn oil. Since no relevant toxicity data were available for the estimation of a lethal dose-level and any existing data have been taken into account, the starting dose-level was 300 mg/kg bw for ethical reasons. After the first assay, the next higher dose-level of 2000 mg/kg bw was tested. Then, as no toxicity was observed at this higher dose-level, the results were confirmed in other females.
Each animal was observed at least once a day for mortality and clinical signs for 15 days. Body weight was recorded before treatment then on days 1, 8 and 15. All surviving animals were necropsied at the end of the observation period.
No unscheduled deaths occurred during the study.
Piloerection was observed in 3 out 6 females given 2000 mg/kg bw 4 hours after treatment on day 1 and on day 2. No clinical signs were observed in other animals.
When compared to laboratory historical control data, a slightly lower body weight gain was noted in one or two females per group between day 1 and day 8 and between day 8 and day 15. When considering the day 1 to day 15 period, the body weight change was lower in two females treated at the dose-level of 300 mg/kg bw and in 4 out of 6 females treated at the dose-level of 2000 mg/kg bw compared to laboratory historical control data.
At necropsy, there were no macroscopic findings related to the test item administration.
The acute oral LD50 was found greater than 2000 mg/kg bw.
