Conditions
Standard Laboratory Conditions:
Air-conditioned with 10-15 air changes per hour and continuously monitored environment with a range for room temperature of 22-24 °C, and for relative humidity between 31-56 %. The animals were provided with a 12-hour artificial fluorescent light, 12-hour dark cycle. Music was played during the light period.
Accommodation: Groups of five in Makrolon type-4 cages with standard softwood bedding during the acclimatization. Individually in Makrolon type-3 cages with standard softwood bedding ("Lignocel", Schill AG, CH-4132 Muttenz) during treatment and observation.
Diet: Pelleted standard Kliba 3433, batch no.43/99 rat maintenance diet (Provimi Kliba AG, CH-4303 Kaiseraugst) available ad libitum.
Water: Community tap water from Füllinsdorf, available ad libitum.
Administration / exposure
- Type of coverage:
- semiocclusive
- Vehicle:
- polyethylene glycol
- Details on dermal exposure:
- Twenty-four hours 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 article 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: 4.0 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:
- Twenty-four hours
- Doses:
- 2000 mg/kg body weight
- No. of animals per sex per dose:
- 5 males and 5 females
- Control animals:
- no
- Details on study design:
- TEST ARTICLE PREPARATION
The test article was placed into a glass beaker on a tared Mettler PM 460 balance and the vehicle (PEG 300) was added. A weight by volume dilution was prepared using a magnetic stirrer as homogenizer. Homogeneity of the test article in the vehicle was maintained during treatment. The preparation was made shortly before each dosing.
OBSERVATIONS
Mortality / Viability: Four times during test day 1 and once daily during days 2-15.
Body weights: On test days 1 (pre-administration), 8 and 15.
Clinical signs: Each animal was examined for changes in appearance and behavior four times during day 1, and once daily during days 2-15. All abnormalities were recorded.
PATHOLOGY
NECROPSY
Necropsies were performed by experienced prosectors. At the end of the observation period all animals were sacrificed by intraperitoneal injection of NARCOREN (Rhône Mérieux GmbH, D-88471 Laupheim) at a dose of at least 2.0 ml/kg body weight (equivalent to at least 320 mg sodium pentobarbitone/kg body weight). The animals were examined macroscopically and all abnormalities recorded. Thereafter, they were discarded. - Statistics:
- No statistical analysis was used.

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The LD50 of FAT 41'029/A after single dermal administration to rats of both sexes, observed over a period of 14 days is, greater than 2000 mg/kg body weight.
- Executive summary:
The acute dermal toxicity of FAT41'029/A was performed according to OECD guideline No. 402 and Directive 92/69/EEC, B.3 under GLP compliance. A group of five male and five female HanIbm: WIST (SPF) rats was treated with FAT 41'029/A at 2000 mg/kg by dermal application. The test article was suspended in vehicle (polyethylene glycol, PEG 300) at a concentration of 0.5 g/ml and administered at a volume of 4 ml/kg. The animals were examined for local and/or clinical signs four times during day 1 and once daily during days 2-15. Mortality/viability were recorded together with clinical signs at the same time intervals. Body weights were recorded on day 1 prior to administration and on days 8 and 15. All animals were necropsied and examined macroscopically.
No deaths occurred during the study. A light orange discoloration of the treated skin sites was observed in all animals after removal of the semi-occlusive dressing only. The body weight of the animals was within the range commonly recorded for animals of this strain and age. No macroscopic findings were observed at necropsy. Thus, the LD50 of FAT 41'029/A after single dermal administration to rats of both sexes, observed over a period of 14 days is, greater than 2000 mg/kg body weight.
