Applicant's summary and conclusion

Interpretation of results:

not classified

Remarks:

Migrated information LD50 >5000 mg/kg body weight Criteria used for interpretation of results: EU

Conclusions:

Based on the lack of clinical toxicity and mortality observed during the study, the acute oral LD50 is >5000 mg/kg.

Executive summary:

In an acute oral toxicity study, 1 group of five fasted Sprague-Dawley albino rats/sex were given a single oral dose of Emery 3004 (undiluted) at a dose of 5000 mg/kg bw and observed for 14 days. 

 

No deaths occurred during the observation period. Clinical changes noted included mild transitory depression and oily and/or scruffy hair coats, which disappeared by the third day in females and the fourth day in males. Necropsies revealed a small spleen and thickened stomach lining in one rat. No other treatment related clinical signs, necropsy findings or changes in body weight were observed. Based on the lack of clinical findings, the acute oral LD50 was determined to be >5000 mg/kg bw for male and female rats.
