Test animals
- Species:
- rat
- Strain:
- Sprague-Dawley
- Sex:
- male/female
- Details on test animals or test system and environmental conditions:
- Animals:
Healthy Sprague-Dawley derived rats, bred on the premises, aged 5 - 6 weeks, having an average body weight of 167 g (Males) and 125 g (Females).
Husbandry:
Rats were caged singly and kept in a room maintained at a temperature of 21 °C (+/-2°). Animals were subjected to 12 hours artificial light and 12 hours darkness in each 24 hour period. A commercial pelleted diet (Oakes Special Diet with added Vit. E) was fed ad lib. Water was available at all times.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The acute oral median lethal dose (LD50) of FAT 20085/A in rats (both sexes) is >5000 mg/kg body weight.
- Executive summary:
The acute oral toxicity of FAT 20085/A was evaluated in a study conducted according to the methodology similar to OECD Guideline 401. In this study, the test article FAT 20085/A was administered as a single dose by oral gavage to rats of both sexes, at a dose of 5000 mg/kg bw in a solution of Carboxymethyl Cellulose. No deaths or clinical signs were observed during the 14-days observation period. At autopsy no changes in organs or tissues caused by the administration of the test compound were seen. Hence, the acute oral toxicity (LD50) of FAT 20085/A in rats of both sexes, observed over a period of 14 days, was estimated to be >5000 mg/kg bw.
