Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- other: Peg 400-water 1:1 v/v
- Details on oral exposure:
- VEHICLE
- Concentration in vehicle: 200 mg/mL
- Amount of vehicle (if gavage): 10 Ml/kg body weight

2, 4 hours after dosing on the day of treatment and daily thereafter. All animals were weighed at allocation to the
study (Day -1), on the day of dosing (Day 1) and on Days 2, 8 and 15.

with particular attention to the gastro-intestinal tract.
Results and discussion
Effect levels
- Key result
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Remarks on result:
- not determinable due to absence of adverse toxic effects
- Mortality:
- No mortality occurred.
- Clinical signs:
- Blue staining on muzzle, dorsal region or perianal region, due to the colour of the substance, was individually observed for a maximum of 10 days after dosing.
- Body weight:
- Changes in body weight observed during the study were within the expected range for this strain and age of animals.
- Gross pathology:
- No abnormalities were observed at necropsy examination.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- These results indicate that the test item did not induce toxic effects in the rat following oral administration of a single dose at a level of 2000 mg/kg body weight. The lack of mortality demonstrates the acute toxicity expected (ATE) to be greater than 2000 mg/kg body weight. The LD50 is > 2000 mg/kg body weight.
- Executive summary:
The acute toxicity of the test item was investigated following a single oral administration to the Sprague Dawley rat followed by a 14-day observation period.
No mortality occurred in the first group of 3 animals dosed at 2000 mg/kg body weight or in the second one, similarly composed, dosed at the same dose level. Clinical signs were limited to blue staining on muzzle, dorsal region or perianal region individually observed for a maximum of 10 days after dosing, which is caused by the coloured test item. Body weight changes recorded during the study were within the expected range for this strain and age of animals.
No abnormalities were observed at necropsy examination performed at the end of the observation period on animals of both groups.
These results indicate that the test item did not induce toxic effects in the rat following oral administration of a single dose at a level of 2000 mg/kg body weight. The lack of mortality demonstrates the acute toxicity expected (ATE) and the mean lethal dose (LD50) to be greater than 2000 mg/kg body weight.
