Number of animals per group 3 males and 3 females
Total number of animals 3 males and 3 females

Identification: Unique cage number and corresponding color-coded spots on the tail. The animals were marked immediately prior to treatment.
Randomization: Selected by hand at time of delivery. No computer generated randomization program.
Acclimatization: Under laboratory conditions, after health examination. Only animals without any visible signs of illness were used for the study.
Husbandry: Room no. 104/ RCC Ltd, Füillinsdorf
Conditions: Standard Laboratory Conditions. Air-conditioned with 10 – 15 air changes per hour, and continuously monitored environment with target ranges for temperature 22 ± 3 °C and for relative humidity between 30 - 70 % (values above 70 % during cleaning process possible), 12 hours fluorescent light 12 hours dark, music during the light period.
Accommodation: In groups of three per sex in Makrolon type-4 cages with wire mesh tops and standard softwood bedding ('Lignocel' Schill AG, CH-4132 Muttenz/Switzerland).
Diet: Pelleted standard Provimi Kliba 3433 rat/mouse maintenance diet, batch no. 67/02 (Provimi Kliba AG, CH-4303 Kaiseraugst Switzerland) ad Iibitum. Results of analyses for contaminants are archived at RCC Ltd, ltingen.
Water: Community tap water from Füllinsdorf ad Iibitum. Results of bacteriological, chemical and contaminant analyses are archived at RCC Ltd, ltingen.
Administration / exposure
- Type of coverage:
- semiocclusive
- Vehicle:
- water
- Remarks:
- Bi-distilled
- Details on dermal exposure:
- One day before treatment, the backs of the animals were clipped with an electric clipper, exposing an area of approximately 10 % of the total body surface. Only those animals without injury or irritation on the skin were used in the test. On test day 1, the test item was applied at a dose of 2000 mg/kg body weight evenly on the intact 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 (application volume/kg body weight: 6 ml). Twenty-four hours after the application the dressing was removed and the skin was flushed with lukewarm tap water and dried with disposable paper towels. Thereafter, the reaction sites were assessed.
- Duration of exposure:
- 24 h
- Doses:
- 2000 mg /kg bw
- No. of animals per sex per dose:
- 5 males and 5 females
- Control animals:
- no
- Details on study design:
- Observations:
Mortality / Viability: Daily during acclimatization and twice daily during days 1-15.
Body weights: On test days 1 (prior to administration), 8 and 15.
Clinical signs: Daily during acclimatization and at approximately 1, 2, 3 and 5 hours after administration on test day 1. Once daily during days 2-15.
Necropsy: All animals were killed at the end of the observation period by an intraperitoneal injection of Vetanarcol at a dose of at least 2.0 ml/kg body weight (equivalent to at least 324 mg sodium pentobarbitone/kg body weight) and discarded after macroscopic examinations were performed. No organs or tissues were retained. - Statistics:
- No statistical analysis was used.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- LD50 (dermal, rat): >2000 mg/kg bw
- Executive summary:
In a GLP-study conducted according to OECD test guideline 402, FAT 40810/A was assessed for its toxicity potential upon single application to skin. Five male and five female HanBrI: WIST (SPF) rats were treated with FAT 40810/A at 2000 mg/kg by dermal application. The test item was diluted in vehicle (purified water) at a concentration of 0.33 g/ml and administered at a volume dosage of 6 ml/kg. The application period was 24 hours. No deaths occurred during the study. No clinical signs were observed during the observation period. Slight red staining of the treated skin area was observed in all animals immediately after removal of the dressing and persisted up to the end of the observation period. Three female animals showed a loss of body weight (0.3 % to 6.2%) one week after treatment whereas one other female animal did not gain body weight during the same period. They recovered at the end of the observation period. The body weight of all other animals was within the range commonly recorded for this strain and age. No macroscopic findings were observed at necropsy except the slight red staining of the treated skin area which was still present. In conclusion the median lethal dose of FAT 40810/A after single dermal administration to rats of both sexes, observed over a period of 14 days is LD50 (rat):greater than 2000 mglkg body weight.
