Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- water
- Details on oral exposure:
- The preparations were made shortly before each dosing.
The test item was weighed into a tared glass beaker on a suitable precision balance and the vehicle added (weight:volume). The mixtures were prepared using a magnetic stirrer or homogenizer, as appropriate.
Homogeneity of the test item in the vehicle was maintained during administration using a magnetic stirrer.
The test item was suspended in vehicle (distilled water) at a concentration of 0.2 g/ml and administered at a volume of 10 ml/kg.
Oral administration was considered to be an appropriate application method as it is a possible route of human exposure during manufacture, handling and use of the test item. - Doses:
- Single oral dose of the test item by gavage at 2000 mg/kg body weight
- No. of animals per sex per dose:
- 3 male and 3 female
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: day1, day 8 and day 15
- Necropsy of survivors performed: yes
- Other examinations performed: clinical signs, body weight, histopathology. - Statistics:
- No statistical analysis was used.
Results and discussion
- Preliminary study:
- The animals received a single oral dose of the test item by gavage at 2000 mg/kg body weight after being fasted for 16 to 20 hours.
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No death occurred during the study.
- Clinical signs:
- other: In male no. 5 ruffled fur was noted two hours until five hours after the treatment. This single finding was considered to be test item related and a non toxic effect. All other animals were without clinical signs.
- Gross pathology:
- No macroscopic findings were observed at necropsy.
- Other findings:
- None

Applicant's summary and conclusion
- Interpretation of results:
- practically nontoxic
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- LD50 of FAT 93527/A for rat observed over a period of 14 days is >2000mg/kg body weight.
- Executive summary:
Following OECD Guidelines for the Testing of Chemicals, Number 423 "Acute Oral Toxicity – Acute Toxic Class Method" wistar rats were exposed to test substance FAT 93527/A to determine median lethal concentration (LD50).
3 male and 3 female HanBrl: WIST (SPF) rats were treated by oral gavage with FAT 93527/A at 2000 mg/kg body weight. The test item was suspended in vehicle (distilled water) at a concentration of 0.2 g/ml and administered at a volume of 10 ml/kg.
The animals were examined for clinical signs daily during the acclimatization period, four
times during test day 1 and once daily during test days 2-15. Mortality/viability was recorded daily during the acclimatization period and together with clinical signs at the same time intervals on test day 1 and at least once daily on test days 2-15. Body weights were recorded on day 1 (prior to administration) and on days 8 and 15. All animals were necropsied and examined macroscopically.
All animals survived until the end of the study period.
In male no. 5 ruffled fur was noted two hours until five hours after the treatment. This single finding was considered to be test item related and a non toxic effect. All other animals were without clinical signs.
The body weight of the animals was within the range commonly recorded for this strain and age. No macroscopic findings were observed at necropsy.
The LD50 dose of FAT 93527/A after single oral administration to rats of both sexes, observed over a period of 14 days is >2000mg/kg body weight.
