Administration / exposure

Route of administration:
oral: unspecified
Vehicle:
other: de-ionized triple glass distilled water
Details on oral exposure:
The test material were dissolved in de-ionized triple glass distilled water
Doses:
2330mg/kg bw
No. of animals per sex per dose:
Total :10
0 mg/kg bw: 5
2330mg/kg bw:5

Applicant's summary and conclusion

Interpretation of results:
other: Not classified
Conclusions:
LD50 was considered to be 2330mg/kg bw. When mouse were treated with test material orally.
Executive summary:

In acute oral toxicity study, maleSwiss strain Albino mice were treated withtest material in dose concentration 2330mg/kg bw orally.The test material were dissolved inde-ionized triple glass distilled water. Each group consisted of 5 animals.50% mortality was observed in treated mouse at 2330 mg/kg bw.Behavioral changes like somnolence (general depressed activity) and convulsions or effect on seizure threshold were observed in treated mice.Therefore, LD50 was considered to be 2330mg/kg bw. When mouse were treated with test material orally.
