Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- other: aqueous Methocel K4M (aqueous hydroxypropylcellulose)
- Details on oral exposure:
- VEHICLE
- Concentration in vehicle: 200 g/L
- Amount of vehicle (if gavage): 10 mL/kg
- Lot/batch no.: ZE10012N02; ZDP 04/13 and 05/13
MAXIMUM DOSE VOLUME APPLIED: 10 mL/kg
CLASS METHOD
- Rationale for the selection of the starting dose: Due to the chemical properties of the test material mortality was not expected at the highest
starting dose of 2000 mg/kg. - Doses:
- 2000 mg/kg bw
- No. of animals per sex per dose:
- 6
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 15 days
- Frequency of observations and weighing:
The behavior and general condition of all rats were monitored for at least 6 hours after administration and then checked daily. Mortality of all rats was monitored for at least 6 hours after administration and then checked
daily. All animals were weighed before treatment ( day 1) and on days 2, 4, 6, 8, 11, 13, and 15 of the
experimental part.
- Necropsy of survivors performed: yes
- Other examinations performed: clinical signs, body weight
Results and discussion
- Preliminary study:
- Prior to testing, an In Vitra Skin Irritation Test was performed with the test item. In this study, no irritating potential could be detected.
Effect levels
- Key result
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality was seen in rats treated with 2000 mg/kg bw.
- Clinical signs:
- No clinical signs of toxicity were seen.
- Body weight:
- The body weight development was inconspicuous throughout the study.
- Gross pathology:
- The gross pathological examination revealed no organ alterations.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the conditions of the present study, it is concluded that the test item has no acute toxic potential and that the LD50 value is higher than 2000 mg/kg bw after single oral administration in female rats.
- Executive summary:
The test material was tested for acute toxicity in 6 female rats after single oral administration of 2000 mg/kg body weight followed by a 2-week observation period.
The study was started with 2000 mg/kg bw in 3 female rats and continued with further 3 females at 2000 mg/kg bw.
No mortality was seen in the 6 female rats treated with 2000 mg/kg bw of the test item. The body weight development was inconspicuous throughout the study. No clinical signs of toxicity were observed. The gross pathological examination revealed no organ alterations.
The LD50 value of the test item is higher than 2000 mg/kg bw after single oral administration in female rats.
