Deviations:

yes

Remarks:

The 1-hour observation for the animals treated at a dose level of 300 mg/kg bw was performed 8 minutes late due to a fire drill. This deviation was considered to have not affected the integrity or validity of the study.

Results and discussion

Preliminary study:

At 300 mg/kg bw there was no mortality and hunched posture was noted 4 hours after dosing. No other signs of systemic toxicity were noted during the observation period. The animal showed expected gains in body weight over the observation period and no abnormalities were noted during necropsy.

Effect levels

Key result

Sex:

female

Dose descriptor:

LD50

Effect level:

> 2 000 mg/kg bw

Based on:

test mat.

Mortality:

One animal (of 5) was found dead 2 days after dosing.

Clinical signs:

other: Hunched posture and noisy respiration were noted during the day of dosing, in the initial treated animal. No signs of systemic toxicity were noted during the observation period in the surviving animals.

Gross pathology:

Abnormalities noted at necropsy of the animal that died during the study were dark and patchy pallor of the liver and dark kidneys. No abnormalities were noted at necropsy of animals that were killed at the end of the study.

Applicant's summary and conclusion

Interpretation of results:

GHS criteria not met

Conclusions:

The acute oral median lethal dose (LD50) of the substance in the female Wistar strain rat was estimnated to be greater than 2000 mg/kg bw.

Executive summary:

In an acute toxicity study the substance was administered to Wistar rats (5 female animals) by oral gavage at a dose level of 2000 mg/kg bw (single administration) following a sighting test with one animal at a dose of 300 mg/kg bw. There was one death 2 days after dosing and hunched posture and noisy respiration were noted during the day of dosing in the initial treated animal. Surviving animals showed expected gains in body weight , except for two animals which showed either no gain in body weight or body weight loss during the first week, but expected gain in body weight during the second week. Abnormalities noted at necropsy of the animal that died during the study were dark and patchy pallor of the liver and dark kidneys. No abnormalities were noted at necropsy of animals that were killed at the end of the study. The acute oral median lethal dose (LD50) of the substance in the female Wistar strain rat was estimnated to be greater than 2000 mg/kg bw.
