Test animals
- Species:
- rat
- Strain:
- Wistar
- Remarks:
- Crl: WI(Han)
- Sex:
- female
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Source: Charles River France, L’Arbresle, France
- Females (if applicable) nulliparous and non-pregnant: yes
- Age at study initiation: Approximately 8 weeks
- Weight at study initiation: 135 to 160 g
- Fasting period before study: No
- Housing: On arrival and following assignment to the study, animals were group housed (up to 5 animals of the same sex and same dosing group together) in polycarbonate cages containing sterilized sawdust as bedding material equipped with water bottles.
- Diet (e.g. ad libitum): Ad libitum except during designated procedures.
- Water (e.g. ad libitum): Ad libitum.
- Acclimation period: At least 5 days.
ENVIRONMENTAL CONDITIONS

Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- water
- Remarks:
- Elix
- Details on oral exposure:
- VEHICLE
- Concentration in vehicle: 200 mg/mL
- Amount of vehicle (if gavage): 10 mL/kg
- Justification for choice of vehicle: Standard vehicle in which the substance dissolved.
MAXIMUM DOSE VOLUME APPLIED: 10 mL/kg
CLASS METHOD (if applicable)
- Rationale for the selection of the starting dose: The dose levels were based on the OECD test guidelines and were selected from the series 5 (lowest dose level), 50, 300 and 2000 (highest dose level) mg/kg body weight. The starting dose level should be the one that is likely to produce mortality in at least some of the animals and was selected based on available toxicity data of the test item. - Doses:
- 2000 mg/kg bw
- No. of animals per sex per dose:
- 6 females dosed at 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 signs were assessed three times on the day of dosing and once daily thereafter. Animals were weighed on Day 1 (pre-dose) and on days 8 and 15.
- Necropsy of survivors performed: yes
- Other examinations performed: None - Statistics:
- Not a requirement of the study guideline
Results and discussion
Effect levels
- Sex:
- female
- Dose descriptor:
- LD50 cut-off
- Effect level:
- > 5 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality occured
- Clinical signs:
- Hunched posture, piloerection, salivation and/or red/orange discoloration of the urine were noted for all animals between Days 1 and 4.
Black/dark faeces was noted for all animals between Days 2 and 5. Black discoloration of the back, left flank, forelegs, head, snout and/or tail were noted for all animals. This was considered to be caused by the salivation of one animal and due to the staining properties of the test item and was therefore considered not toxicologically relevant. - Body weight:
- The mean body weight gain shown by the animals over the study period was considered to be similar to that expected for normal untreated animals of the same age and strain.
- Gross pathology:
- No abnormalities were found at macroscopic post mortem examination of the animals.
- Other findings:
- None noted
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The oral LD50 value of the test substance in Wistar rats was established to exceed 2000 mg/kg body weight. According to the OECD 423 test guideline, the LD50 cut-off value was considered to exceed 5000 mg/kg body weight.
