Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- water
- Details on oral exposure:
- For the 300 mg/kg group, the test substance was dosed undiluted. The dose volume of 0.29 mL/kg.
For the 50 mg/kg group, the test substance was dosed at a diluted concentration of 5 mg/mL. The dose volume of 10 mL/kg.
CLASS METHOD (if applicable)
- Rationale for the selection of the starting dose: The recent toxicity information from 10-D dose range finding study shows that the substance caused mortality (one rat died at study day 1, 3, 4) when dosed repeatedly at 200 mg/kg bw (Baracani, R. (2014). - Doses:
- 300 mg/kg bw, 50 mg/kg bw
- No. of animals per sex per dose:
- 3 females / dose (300mg/kg) and 6 (3+3) females / dose (50mg/kg)
- Control animals:
- no
- Details on study design:
- All 3 females at 300 mg/kg died. Therefore, 3 females were dosed at 50 mg/kg. No mortality was observed, and 3 additional females were dosed at 50 mg/kg. Again, no mortality was observed, and therefore, no additional rats were dosed.
- Duration of observation period following administration: 14 days
- Frequency of observations and weighing: The rats were observed at approximately 15 minutes (± 5 minutes) and 1, 2 and 4 hours post-dosing on study day 0 and twice daily, once in the morning and once in the afternoon.
- Necropsy of survivors performed: yes
- Other examinations performed: clinical signs, body weight,organ weights
Results and discussion
Effect levels
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 50 - < 300 mg/kg bw
- Based on:
- test mat.
- Remarks on result:
- other: mortality
- Mortality:
- 300 mg/kg 3/3
50 mg/kg 0/6 - Clinical signs:
- other: There were no clinical observations for the 50 mg/kg group females.
- Gross pathology:
- There were no test substance-related macroscopic findings. One female in the 300 mg/kg group that died had clear uterine contents.
- Other findings:
- - Organ weights: not measured
- Histopathology: not done
- Potential target organs: not found
- Other observations: not done
Applicant's summary and conclusion
- Interpretation of results:
- Toxicity Category III
- Remarks:
- Migrated information This study result is used for a classification Criteria used for interpretation of results: EU
- Conclusions:
- Fasted female albino rats were administered with HaloSalt once orally via gavage. The estimated LD50 of Halo Salt was greater than 50 mg/kg but less than 300 mg/kg.
- Executive summary:
The objectives of this study were to determine the estimated acute oral median lethal dose and evaluate potential systemic toxicity of the test substance when administered as a single dose to albino rats.
The study is considered reliable without restrictions since the study is carried out according to OECD No. 423 guideline and in compliance with principles of Good Laboratory Paractice (GLP).
Based on the results of this study, the estimated LD50 of Halo Salt was greater than 50 mg/kg but less than 300 mg/kg when administered once orally via gavage to fasted female albino rats (Acute Tox. 3).
