Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:

- Remarks:
- as a flowable gel in distilled water
- Details on oral exposure:
- TEST ITEM PREPARATION
- The test item was formulated within 2 hours of being applied to the test system. It is assumed that the formulation was stable for this duration.
- No analysis was conducted to determine the homogeneity, concentration or stability of the test item formulation.
- Concentration in vehicle: 30 mg/mL and 200 mg/mL corresponding to dose-levels of 300 and 2000 mg/kg bw
DOSE VOLUME APPLIED:
10 mL/kg, calculated according to the fasted body weight at the time of dosing. - Doses:
- 300 and 2000 mg/kg bw
- No. of animals per sex per dose:
- - At first, 1 animal was treated with 300 mg/kg bw
- In the absence of toxicity, another animal was treated with 2000 mg/kg bw
- In absence of mortality, 4 additional animals were treated with 2000 mg/kg bw - Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Clinical observations were made 30 minutes, 1, 2 and 4 hours after dosing and then daily. Individual body weights were recorded on Day 0 (the day of dosing) and on days 7 and 14.
- Necropsy of survivors performed: yes, At the end of the observation period the animals were killed by ascending concentrations of carbon dioxide, death was then confirmed by cervical dislocation. All animals were subjected to gross necropsy. This consisted of an external examination and opening of the abdominal and thoracic cavities. The appearance of any macroscopic abnormalities was recorded. No tissues were retained.
Results and discussion
Effect levels
- Key result
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- There was no mortality in any of the treatment groups.
- Clinical signs:
- - 300 mg/kg bw: No signs of systemic toxicity were noted during the observation period.
- 2000 mg/kg bw: Hunched posture was noted 2 and 4 hours after dosing in the initial treated animal. No signs of systemic toxicity were noted during the observation period in the four additional treated animals. - Body weight:
- - 300 mg/kg bw: The animal showed expected gains in body weight over the observation period.
- 2000 mg/kg bw: Animals showed expected gains in body weight over the observation period except for one animal which showed body weight loss during the first week with expected gain in body weight during the second week. - Gross pathology:
- No abnormalities were noted at necropsy in any of the treatment groups.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The acute oral toxicity test showed an LD50 > 2000 mg/kg bw
- Executive summary:
The acute oral toxicity of the test substance was assessed according to the Fixed dose Method (OECD guideline 420) and GLP principles. In this study one female Wistar (RCCHanTM :WIST) rat was dosed with 300 mg/kg bw test substance by gavage. Since no toxicity was observed, an additional female was treated with 2000 mg/kg bw and subsequently, since no mortality occurred, 4 additional females were treated at this dose. During the 14 day observation period no mortality was observed. Clinical signs were only observed in the first animal dosed at 2000 mg/kg bw: a hunched posture was noted 2 and 4 hours after dosing in this animal. No signs of systemic toxicity were noted during the observation period in the four additional treated animals. All animals showed expected gains in body weight over the observation period except for one animal in the 2000 mg/kg bw dose group which showed body weight loss during the first week with expected gain in body weight during the second week. Under the conditions of the test, the acute oral LD50 for the test substance in rat was determined to be above 2000 mg/kg bw. Based on these results, the test substance is not considered to be acutely harmful.
