ENVIRONMENTAL CONDITIONS
Air-conditioned with ranges for room temperature 17-23 °C, relative humidity 30-70 % and approximately 10-15 air changes per hour. 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. The animals were provided with an automatically controlled light cycle of 12 hours light and 12 hours dark. Music was played during the daytime light period.

- Details on study design:
- TEST ITEM PREPARATION
0.5 g (per animal) of FAT 40824/A was weighed as delivered by the Sponsor and then moistened with approximately 0.5 mL of purified water before application.
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 40824/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.
SKIN OBSERVATION TIME POINTS AND TERMINATION: The skin reaction was assessed at approximately 1, 24, 48 and 72 hours, as well as 7 and 10 days after exposure (removal of the dressing, gauze patch and test item).
All rabbits were sacrificed by an intravenous injection of Vetanarcol into the ear vein at a dose of at least 1 mL/kg body weight (equivalent to 162 mg sodium pentobarbitone/kg body weight) and discarded.

- Remarks on result:
- no indication of irritation
- Irritant / corrosive response data:
- Signs such as erythema could not be evaluated in all animals at the 1-hour reading due to red marked staining produced by the test item at the application site which persisted in one animal until the 24-hour examination. Where evaluation was permitted, 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.
Neither alterations of the treated skin were observed nor were corrosive effects evident on the skin. - Other effects:
- No clinical signs of systemic toxicity were observed in the animals during the study and no mortality occurred.
The test item caused a slight to marked red staining at the test site of all animals from the 1- to the 72-hour reading and persisted as slight staining in one animal until test day 7.
The body weights of all 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 40824/A is considered to be "not irritating" to rabbit skin.
- Executive summary:
In a GLP compliant study, the primary skin irritation potential of test article was investigated according to OECD test guideline No. 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 and 10 days after removal of the dressing.
Signs such as erythema could not be evaluated in all animals at the 1-hour reading due to red marked staining produced by the test item at the application site which persisted in one animal until the 24-hour examination. Where evaluation was permitted, 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 test article to the skin did however cause a slight to marked red staining at the test site of all animals from the 1- to the 72-hour reading and persisted as slight staining in one animal until test day 7. No corrosive effects were noted on the treated skin of any animal at any of the measuring intervals and no clinical signs were observed. Based on the study results, FAT 40824/A is considered to be "not irritating" to rabbit skin.
