- TEST ANIMALS
- Source: Harlan France, Zl Le Marcourlet, 03800 Gannat/France
- Age at treatment: 12-13 weeks
- Housing: Individually in stainless steel cages equipped with feed hoppers and drinking water bowls. Wood blocks (RCC Ltd, Füllinsdorf) and haysticks 4642 (batch no. 77/05, Provimi Kliba AG) were provided for gnawing.
- Diet: Pelleted standard Provimi Kliba 3418 rabbit maintenance diet ad libitum (batch no. 24/06) provided by Provimi Kliba AG, CH-4303 Kaiseraugst.
- Water: Community tap water from Füllinsdorf, ad libitum.
- Acclimation period: Under laboratory conditions after health examination. Only animals without any visual signs of illness were used for the study.
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 17-23
- Humidity (%): 30-70
- Air changes (per hr): 10-15
- Photoperiod (hrs dark / hrs light): 12/12
Room temperature and humidity were monitored continuously and values outside of these ranges may have occasionally occurred, usually following room cleaning. These transient variations are considered not to have any influence on the study and, therefore, these data are not reported but are retained at RCC.
Test system
- Type of coverage:
- semiocclusive
- Preparation of test site:
- clipped
- Remarks:
- using electric clipper
- Vehicle:
- water
- Controls:
- no
- Amount / concentration applied:
- 0.5 g test substance moistened with approximately 0.5 mL purified water.
- Duration of treatment / exposure:
- 4 h
- Observation period:
- 7 days
- Number of animals:
- 1 male, 2 females
- Details on study design:
- TREATMENT
Four days before treatment, the left flank was clipped with an electric clipper, exposing an area of approximately 100 cm² (10 cm x 10 cm). The skin of the animals was examined one day before treatment, and regrown fur of all animals was clipped again. Animals with overt signs of skin injury or marked irritation which may have interfered with the interpretation of the results were not used in the test. On the day of treatment, 0.5 g of FAT 40826/A was placed on a surgical gauze patch (ca. 4 cm x 4 cm). This gauze patch was applied to the intact skin of the clipped area. The patch was covered with a semi-occlusive dressing. The dressing was wrapped around the abdomen and anchored with tape. The duration of treatment was 4 hours. Then the dressing was removed and the skin was flushed with lukewarm tap water to clean the application site.
OBSERVATIONS
Viability/Mortality: Daily from acclimatization of the animals to the termination of test.
Clinical signs: Daily from acclimatization of the animals to the termination of test.
Body weights: At start of acclimatization, on the day of application and at termination of observation.
Necropsy: The animals were not sacrificed. No signs of irritation were observed on the treated skin following the application of the test item. For ethical reasons and in the interest of animal welfare, the animals were therefore re-used for the eye irritation study (RCC Study A73675.) using the same test item.
SCORING SYSTEM:
The skin reaction was assessed according to the numerical scoring system listed in the Commission Directive 2004/73/EC, April 29, 2004 approximately 1, 24, 48 and 72 hours, as well as 7 days after the removal of the dressing, gauze patch and test item.

- Irritant / corrosive response data:
- - The test item did not elicit any skin reactions at the application site of any animal of the observation times (all scores 0). The individual mean score for erythema/eschar and oedema for each of the three animals was therefore 0.
- Neither alterations of the treated skin were observed nor were corrosive effects evident on the skin. - Other effects:
- - Slight orange staining of the treated skin produced by the test item was observed in all animals from the 1- to the 48-hour reading and persisted in two animals until the 72-hour reading.
- No clinical signs of systemic toxicity were observed in the animals during the study and no mortality occurred.
- A slight loss of weight (1.7 %) was noted during the acclimatization period in one animal. The animal recovered at the end of the observation period. The body weights of the other rabbits were considered to be within the normal range of variability.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- FAT 40826/A is considered to be not irritating or corrosive to the rabbit skin.
- Executive summary:
A GLP-compliant skin irritation study with FAT 40826/A was carried out according to OECD test guideline 404. The test item was applied by topical semi-occlusive application of 0.5 g to the intact left flank of each of three young adult New Zealand White rabbits. The duration of treatment was four hours. The scoring of skin reactions was performed 1, 24, 48 and 72 hours, as well as 7 days after removal of the dressing. The test item did not elicit any skin reactions at the application site of any animal at any of the observation times (all scores 0). The individual mean score for erythema/eschar and oedema for each of the three animals was therefore 0. The application of FAT 40826/A to the skin resulted in no signs of irritation. However, the test item caused slight orange staining of the treated skin in all animals. No corrosive effects were noted on the treated skin of any animal at any of the measuring intervals and no clinical signs were observed. Thus, the test item did not induce significant or irreversible damage to the skin. Based on the study results, FAT 40826/A is considered to be "not irritating" to rabbit skin.
