ENVIRONMENTAL CONDITIONS
- Temperature (°C): 22 ± 3
- Humidity (%): 40-70
- Air changes (per hr): 10-15
- Photoperiod (hrs dark / hrs light): 12/12
Administration / exposure
- Type of coverage:
- semiocclusive
- Vehicle:
- water
- Details on dermal exposure:
- Approximately 24 hours before treatment, the backs of the animals were shaved with an electric clipper, exposing an area of approximately 10 % of the total body surface. On test day 1, 4 mL at 2000 mg/kg test article was applied evenly on the skin with a syringe and covered with a semi-occlusive dressing. The dressing was wrapped around the abdomen and fixed with an elastic adhesive bandage. Twenty-four hours after the application, the dressing was removed. The treated skin was washed with lukewarm tap water and dried with disposable paper towels and the skin reaction was assessed.
- Duration of exposure:
- 24 hours
- Doses:
- 2000 mg/kg bw
- No. of animals per sex per dose:
- 5
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Mortality/viability were measured four times during test day 1 (pre-administration) and daily during days 2 - 15.
- Body weights were measured on day 1, 8 and 15.
- All animals were necropsied.
- Each animal had an examination for changes in appearance and behaviour four times during day 1, and daily during days 2-15. All abnormalities were recorded. - Statistics:
- The LOGIT-Model could not be applied to the observed rate of death. The toxicity was estimated without use of a statistical model.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The acute dermal median lethal dose (LD50) of FAT 40400/A was estimated to be >2000 mg/kg bw.
- Executive summary:
In a GLP-compliant dermal toxicity study, performed according to OECD guideline 402, Wistar rats (5/sex) were administered FAT 40400/A at the dose of 2000 mg/kg bw. The test substance was dissolved in water and applied on the skin with a syringe and covered with a semi-occlusive dressing for 24 hours. The treated skin was washed after 24 hours and a 14-day observation period followed. No mortality was observed during this period. Scales and discoloration were observed until termination of the study. No macroscopic findings were noted. Therefore, the acute dermal median lethal dose (LD50) of FAT 40400/A was estimated to be >2000 mg/kg bw.
