ANIMAL HUSBANDRY
Conditions : Air-conditioned room with approximately 15 air changes per hour and the environment controlled with optimal conditions considered as being a temperature of 21 °C and a relative humidity of 50%. Fluctuations from these optimal conditions were noted, but were considered not to have affected study integrity. Lighting was 12 hours artificial fluorescent light and 12 hours dark per day.
Accommodation: Individually housed in labelled polycarbonate cages containing purified sawdust as bedding material (Woody SPF, supplied by B.M.I., Helmond, The Netherlands). Certificates of analysis were examined and then retained in the NOTOX archives. Acclimatisation period was at least 5 days before start of treatment under laboratory conditions.
Diet: Free access to standard pelleted laboratory animal diet (from Carfil Quality BVBA, Oud-Turnhout, Belgium). Certificates of analysis were examined and then retained in the NOTOX archives.
Administration / exposure
- Type of coverage:
- occlusive
- Vehicle:
- CMC (carboxymethyl cellulose)
- Remarks:
- 1%
- Details on dermal exposure:
- TREATMENT
Method: Dermal application.
Shaving: One day before exposure (day -1) an area of approximately 5x7 cm on the back of the animal was clipped.
Application: The test substance formulation was applied to an area of approximately 25 cm² (5x5 cm) for males and 18 cm² (3.5x5 cm) for females by application on a gauze patch fixed successively to aluminium foil and flexible bandage (Coban, 3M, St. Paul, U.S.A.), with drops of petrolatum.
Frequency: Once, on day 1.
Dose level: (volume) 2000 mg/kg (10 ml/kg) body weight.
Application period: 24 hours, thereafter dressings were removed and residual test substance removed using a tissue moistened with tap water. - Duration of exposure:
- 24 h
- Doses:
- 2000 mg/kg bw (single application)
- No. of animals per sex per dose:
- 5 males and 5 females
- Control animals:
- not required
- Details on study design:
- OBSERVATIONS
Mortality/Viability checks: Twice daily.
Body weight recordings: Days 1 (pre-administration), 8 and 15.
Clinical signs: At periodic intervals on the day of treatment (day 1) and once daily thereafter, until day 15. The time of onset, degree and duration were recorded.
Necropsy: At the end of the observation period, all animals were sacrificed by oxygen/carbon dioxide asphyxiation and subjected to necropsy. Descriptions of all internal macroscopic abnormalities were recorded. - Statistics:
- No statistical analysis was performed.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The acute dermal LD50 of FAT 40543/A is >2000 mg/kg bw.
- Executive summary:
The study was carried out in accordance with OECD Guideline No. 402, "Acute Dermal Toxicity" and EEC Directive 92/69/EEC, Part B.3, "Acute Toxicity - Dermal" to assess dermal toxicity of test substance on single application. A group of rats, containing 5 males and 5 females, was exposed to FAT 40543/A by dermal application at 2000 mg/kg bw for 24 hours. Animals were subjected to daily observations and weekly determination of body weight. Macroscopic examination was performed after terminal sacrifice (day 15). No mortality was observed. Lethargy was observed in all animals at 4 hours after treatment and had resolved by day 2. Red staining of the skin, the treated area in particular, was observed in all animals and persisted in several animals throughout the observation period. Body weight gain during the observation period was within the range expected for rats used in this type of study. No abnormalities were found in the animals at macroscopic post mortem examination. Based on the findings of the study, the dermal LD50 value of FAT40543/A in rats was established to be greater than 2000 mg/kg bw.
