- Executive summary:
The skin irritation in albino rabbits after single application was performed to determine the irritant potency of the test item on the albino rabbit skin. The procedure used is described in the Proposed Guidelines of the United States Environmental Agency (EPA) 163.81-5 "Primary dermal irritation study", Federal Register Vol. 43, No. 163, August 22, 1978. The test was performed on 3 male and 3 female (New Zealand White rabbits), checked for normal skin conditions. Before treatment the flanks of the rabbits were shaved and immediately before treatment, the shaven skin on one side was slightly scarified. A gauze patch bearing 0.5 g of the test substance was applied to the prepared abraded and intact skin. The patches were covered by an impermeable material. Patches were held in place for 24 hours. Observations were made at 24, 48, 72 hours and 7 days, respectively. Due to intensive staining by the test compound erythema was not assessable. For the purpose of calculating the primary irritation index erythema was assumed to be equal to edema based on the correlation existing (Marzulli and Maibach, Fol. Cosm. Tox. 13, 355, 1975). The 24/48/72h mean erythema score and edema score was found to be 0 and 1 respectively. The effects were fully reversible within 7 days of observation period. Under the conditions of the present experiment FAT 36091/D was found to cause a minimal to slight irritation when applied to intact and abraded rabbit skin. The calculated primary irritation index was 1. FAT 36091/D was found to cause a minimal to slight irritation when applied to intact and abraded rabbit skin. In general, abration represents an elevated test condition that does normally not need to be taken into account for evaluation of the hazard assessment. Therefore, results on abraded skin are not taken into account.

- Executive summary:
The eye irritation in New Zaeland White after single application was performed to determined the irritant potency of the test item on the rabbit eyes. This test was based on the OECD Guideline No. 405, adopted May 12, 1981, by the OECD council, and on Annex V, part B of Council Directive 79/831/EEC (Commission Directive 84/449/EEC of April 25, 1984; Official Journal L251, September 19, 1984). 0.1 ml (42 mg) of FAT 36091/F was placed into the conjunctival sac of the left eye of each animal, after gently pulling away the lower lid from the eyeball. The lids were then held together for about one second in order to prevent loss of the test article. The right eye remained untreated and served as a control. The animals were checked daily for systemic symptoms and mortality. Because reactions were observed within 72 hours after instillation of the test article, the observation period was extended to 7 days to determine the reversibility of the eye reactions. No effects were observed on corneal opacity, iris and chemosis. Mean 24/48/72h conjuctiva score was found to be 0.78. According to the EEC classification of the results obtained 24/48.72 hours after instillation FAT 36091/F can be classified as non-irritant to albino rabbit's eye. The eye reactions observed were reversible within 72 hours.

Additional information
A key study was performed to determine the potential of FAT 36091/E (Study number: 875189) to induce irritation/corrosion to albinos rabbits skin according to the OECD Guideline 404 (Acute Dermal Irritation / Corrosion). The test was performed on 3 rabbits. A gauze patch bearing 0.5 gr. of the test item was applied to the flank of each animals. Patched were held in place for 4 hours. During the experiment, no mortality occuried and no edema or erythema were observed. The primary index irritation was found to be 0. The test item, did not induce skin irritation when applied to the shaved albino rabbits skin. Three supporting studies were carried out with FAT 36091 on different batches (A and D) according to the Proposed Guidelines of the United States Environmental Agency (EPA) 163.81-5 "Primary dermal irritation study", Federal Register Vol. 43, No. 163, August 22, 1978.
- Batch D: two studies were performed to determine the skin irritation in the rabbit after a single application.
- In the study report number 801358, FAT 36091/D was found to be a minimal irritant with a primary irritation index of 0.9
- In the study report number 791713, FAT 36091/D was found to cause slight irritation when applied to intact and abraded skin. The primary skin irritation index was 1.1.
Skin reaction were fully reversible within 7 days as reported in the study number 791713 and fully reversible within 7 days for the intact skin in the study number 801358.
- Batch A: One more study, (study number 385/19), was performed to determine the skin irritation in the rabbit after a single application. The calculated primary irritation index was found to be 4.2 and under these the test item was found to cause marked irritation when applied to intact and extreme irritation when applied to abraded rabbit skin. One more supporting study was carried out with FAT 36091/A according to the the procedure used is described in the Proposed Guidelines of the United States Environmental Agency (EPA) 163.81-5 "Primary dermal irritation study", Federal Register Vol. 43, No. 163, August 22, 1978.
-Batch A (study number 801357): Due to intensive staining by the test compound, erythema was not assessable. For the purpose of calculationg the primary irritation index erythema was assumed to be equal to edema based on the correlation existing (Marzulli and Maibach, Fol. Cosm. Tox. 13, 355, 1975). The calculated primary irritation index was 1. The skin reactions were reversible within 7 days for the intact and abraded skin.
FAT 36091/A was found to cause minimal to slight irritaion when applied to intact and abraded rabbit skin but classified as non-irritant to the rabbit skin. Considering the above key and supporting studies FAT 36091 can be considered as non-irritant to skin of rabbits.
A key study was performed to determine the potential of FAT 36091/A to induce irritation to rabbit eye according to OECD guideline 405 and no GLP methodology. Because reaction were observed within 72 hours after instillation of the test article, the observation period was extended to 7 days determine the reversibility of the eye reactions. According to the EEC classification of the results obtained 24 to 72 hours after instillation, FAT 36091/F can be classified as non-irritant to albino rabbit. The eye reaction observed were reversible within 7 days. FAT 36091/F is to be considered as a non-irritant to the eye of rabbits. The two supporting studies were carried out with FAT 36091 (batch A and D) to determine the eye irritation according to non GLP guideline methods.
The primary irritation index, for batch A, was found to be 7.5 for unrinsed eyes and 7.1 for rinsed eyes. Rinsing the eye following instaillation has no significant effect. The primary irritation index, for batch D, was found to be 0.7 for unrinsed eyes and 0.0 for rinsed eyes.
FAT 36091/A is considered to be a slightly irritant to the rabbit eye mucosa. FAT 36091/D is considered to be a minimal irritant to the rabbit eye mucosa. Since the reactions in the supporting studies are fully reversible, it is considered as non-irritant to eye.
Therefore, considering the results from the key and supporting studies, FAT 36091 is considered as non-irritant on skin and eye.
Justification for selection of skin irritation / corrosion
endpoint:
Most recent study available and the experiment was performed
according to the OECD Guideline 404.
Justification for selection of eye irritation endpoint:
Most recent study available and the experiment was performed
according to the OECD Guideline 405.
Justification for classification or non-classification
Based on the above mentioned results, the substance does not need to be classified for eye irritation. The degree of skin and eye irritation was insufficient for classification and labelling and thus no classification is proposed for skin irritation.
Therefore, FAT 36091 is classified as non-irritant for skin and eyes.
