- Source: Russian breed
- Weight at study initiation: 1.5 to 2 kgs
- Housing: Separately in V2A wire cages.
- Diet: NAFAG, Gossau SG, rabbit food ad libitum
- Water: ad libitum
Test system
- Type of coverage:
- occlusive
- Preparation of test site:
- shaved
- Remarks:
- As well as sacrificed skin
- Vehicle:
- other: 50 % polyethylene glycol trituration (PEG 400)
- Controls:
- yes, concurrent no treatment
- Amount / concentration applied:
- FAT 40061/A was applied to each side in quantities of 0.5 g. Before application a 50 % polyethylene glycol trituration (PEG 400) was made.
- Duration of treatment / exposure:
- 24 hours
- Observation period:
- 72 hours
- Number of animals:
- 3 males and 3 females
- Details on study design:
- Six rabbits (3 males/3 females) of the Russian breed, weighing 1.5 to 2 kgs,were shaved on the whole back and flanks two days before treatment with an electric clipper. In order to prevent injuries by bites the rabbits were kept separately in V2A wire cages, where they had access to food (NAFAG, Gossau SG, rabbit food) and water ad libitum. The shaven skin on the left side was slightly scarified immediately before treatment.
A gauze patch 2.5 x 2.5 cm was soaked with the test substance and immediately applied to the prepared skin. The patch was covered with a plastic film 5 x 5 cm, which was fixed to the body with adhesive tape. FAT 40061/A was applied to each side in quantities of 0.5 g. Before application a 50 %.polyethylene glycol trituration (PEG 400) was made. The gauze patches were removed 24 hours after the application. The reaction of the skin was appraised upon removal and 72 hours after it, based on the following evaluation scheme.
Evaluation of Skin Reactions
Erythema and eschar formation
0: No erythema
1: Very slight erythema (barely perceptible)
2: Well defined erythema
3: Moderate to severe erythema
4: Severe erythema (beet redness) to slight eschar formation (injuries in depth)
Edema formation
0: No edema
1: Very slight edema (barely perceptible)
2: Slight edema (edges of area well defined by definite raising)
3: Moderate edema (raised approximately 1 mm)
4: Severe edema (raised more than 1 mm and extending beyond area of exposure)

Any other information on results incl. tables
The primary irritation index as the measure of the acute skin irritation provoked by the substance is defined as the average of all the ratings found after 24 and 72 hours on the intact and slightly scarified skin. Compounds producing combined averages (primary irritation indexes) of 2 or less are only mildly irritating; whereas those with indexes from 2 to 5 are moderate irritants, and those with scores above 6 are considered severe irritants. The primary irritation index of FAT 40061/A was 0.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- FAT 40061/A is to be considered as non-irritant to the skin of rabbits.
- Executive summary:
A study was conducted to assess the potential of FAT 40061/A to cause acute irritation on the rabbit skin. The procedure adopted was the patch-test technique described in the "Appraisal of the Safety of Chemicals in Foods, Drugs and Cosmetics" (1959) of the US Association of Food and Drug Officials (AFDO). Six rabbits (3 males/3 females) of the Russian breed were used in the occlusive patch test. The rabbits were shaved on the whole back and flanks two days before treatment with an electric clipper. In order to prevent injuries by bites the rabbits were kept separately in V2A wire cages, where they had access to food (NAFAG, Gossau SG, rabbit food) and water ad libitum. The shaven skin on the left side was slightly scarified immediately before treatment. A gauze patch 2.5 x 2.5 cm was soaked with the test substance and immediately applied to the prepared skin. The patch was covered with a plastic film 5 x 5 cm, which was fixed to the body with adhesive tape. FAT 40061/A was applied to each side in quantities of 0.5 g. Before application a 50 % polyethylene glycol trituration (PEG 400) was made. The gauze patches were removed 2 4 hours after the application. The reaction of the skin was appraised upon removal and 72 hours after it. The primary irritation index as the measure of the acute irritation to the skin of rabbits was found to be 0. Therefore, FAT 40061/A is to be considered as non-irritant to the skin of rabbits.
