DOSAGE PREPARATION:
FAT 80'023/G was diluted to achieve a concentration suitable for the dose levels selected for this test. - Doses:
- 500; 1000; 2,500 and 5,000 mg/kg body weight

- 5
- Control animals:
- not specified

Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- 2 287 mg/kg bw
- 95% CL:
- 1 607 - 3 876
- Mortality:
- Males: No mortality was observed in the dose groups of 500, 1000 and 2500 mg/kg body weight. 5 / 5 animlas died within 24 hours in the high dose group of 5000 mg/kg body weight.
Females: No mortality was observed in the low dose group of 500 mg/kg body weight. With 1000 mg/kg body weight one animal died within 3 days. In the 2500 mg/kg body weight dose group one animal died after 3, 4, 5 and 9 days, respectively. In the highest dose group of 5000 mg/kg body weight 3 animals died within 24 hours, one animal within 3 and one within 4 days. - Clinical signs:
- other: The surviving animals recovered within 8 to 10 days. 500 mg/kg body weight: dyspnoea (day 1 - 6, slight), exophthalmos (day 1 - 7, slight), ruffeled fur (day 1 - 5, slight), curved body position (day 1 - 3, slight). 1000 mg/kg body weight: sedation (hour
- Gross pathology:
- No gross organ changes were observed.
- Other findings:
- No data
Applicant's summary and conclusion
- Interpretation of results:
- practically nontoxic
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Based on the test results the substance is considered to be not acute toxic via oral application.
- Executive summary:
The acute oral LD50 of FAT 80'0 23/G in rats of both sexes observed over a period of 14 days is 2287 (1607-3876) mg/kg. The test material is therefore not toxic to the rat by this route of administration.
