- TEST ARTICLE PREPARATION
The test article was placed into a glass beaker on a tared Mettler PE 360 balance and the vehicle (bi-distilled water) was added. A weight/volume dilution was prepared using a homogenizer (Ultra-Turrax, Janke and Kunkel, D-7813 Staufen).
Homogeneity of the test article in the vehicle was maintained during treatment using a magnetic stirrer (Janke and Kunkel, D-7813 Staufen).
The preparation was made immediately prior to each dosing.
TREATMENT
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 the 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, dried with disposable paper towels and the skin reaction was assessed according to the method of Noakes and Sanderson (Noakes, D.N. and Sanderson, D.M. "A Method for Determining the Dermal Toxicity of Pesticides". Brit. J. Industr. Med., 26, 59-64, 1969).
Application volume/ kg body weight: 4 mL at 2000 mg/kg bw - 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: Four times during test day 1, and daily during days 2-15.
Body Weights: Test days 1 (pre-administra'tion), 8 and 15.
Clinical Signs:
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. Due to the 24-hour semi-occlusive treatment, the local findings were observed starting with day 2 of test.
Necropsy: Necropsies were performed by experienced prosectors. All animals were necropsied. All animals were killed by intraperitoneal injection of sodium pentobarbitone. - 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 LD50 of FAT 31064/A was determined to be >2000 mg/kg bw.
- Executive summary:
The acute dermal toxicity potential of FAT 31064/A was assessed in a study carried out in accordance with OECD Guideline No. 402, "Acute Dermal Toxicity" and EEC Directive 92/69/EEC, Part B.3, "Acute Toxicity - Dermal". In this study, the test substance was administered to five rats of each sex 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. No mortality occurred. No systemic symptoms were seen. Bluish skin on back was observed after the removal of the patches in all exposed animals. Female no. 6 showed loss of weight between days 1 and 8 of test. The body weight gain of the other animals were not affected throughout the study by test article treatment. No macroscopical organ changes were noted during the necropsies. Based on the findings of the study, the acute dermal LD50 for FAT 31064/A was determined to be >2000 mg/kg bw.
