Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- LD50 was considered to be 4740 mg/kg bw when mice were treated with Sodium fluorescein orally.
- Executive summary:
In a acute oral toxicity study, mice were treated with Sodium fluoresce in the concentration of 4740 mg/kg bw. 50 % mortality was observed in treated mice at 4740 mg/kg bw. Therefore, LD50 was considered to be 4740 mg/kg bw when mice were treated with Sodium fluorescein orally.
