- Direct MTT Reduction
The direct MTT reduction test was inconclusive due to the dark blue color of the test item. Therefore, an additional procedure using freeze killed tissues was performed to assess for the possibility of direct MTT reduction. An additional procedure was also performed using viable tissues to assess for the possibility of color interference. The results of the additional procedures showed a negligible degree of interference due to possible direct reduction of MTT or color interference. It was therefore considered unnecessary to use the results of the additional procedures for quantitative correction of results and reporting purposes. - Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test item was considered to be non-corrosive to the skin.
- Executive summary:
The corrosivity potential of the test item was evaluated using the EpiDerm™ Human Skin Model after treatment periods of 3 and 60 minutes. Corrosion is directly related to cytotoxicity in the EpiDerm™ tissue. Cytotoxicity is determined by the reduction of MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl-tetrazolium bromide) to formazan by viable cells in the test item treated tissues relative to the corresponding negative control. The results are used to make a prediction of the corrosivity potential of the test item. Duplicate tissues were treated with the test item for exposure periods of 3 and 60 minutes. The direct MTT reduction test was inconclusive due to the dark blue color of the test item. There was a possibility that if the test item could not be totally rinsed off the tissues, any residual test item present on or in the tissue may directly reduce MTT or cause color interference and could have given rise to a false negative result. Therefore, an additional procedure using freeze killed tissues was performed to assess for the possibility of direct MTT reduction. An additional procedure was also performed using viable tissues to assess for the possibility of color interference. At the end of the exposure period the test item was rinsed from each tissue before the tissues were taken for MTT-loading. After MTT loading each tissue was placed in 2 mL Isopropanol for MTT extraction. At the end of the formazan extraction period each well was mixed thoroughly and triplicate 200 mL samples were transferred to the appropriate wells of a pre-labeled 96-well plate. The optical density (OD) was measured at 562 nm (OD562). Data are presented in the form of percentage viability (MTT reduction in the test item treated tissues relative to negative control tissues). The results of the additional procedures showed a negligible degree of interference due to possible direct reduction of MTT or color interference. It was therefore considered unnecessary to use the results of the additional procedures for quantitative correction of results or for reporting purposes. The relative mean viabilities of the test item treated tissues were as follows:
60 minute exposure: 105.8 %
3 minute exposure: 108.8 %
The quality criteria required for acceptance of results in the test were satisfied. The test item was considered to be non-corrosive to the skin.

- TEST SITE
- Area of exposure: A gauze patch (20 cm²) bearing 0.5 ml of the test substance was applied to the flank.
An area of at least 6 cm² was shaved on both flanks of the animals approximately 24 hours before treatment. A gauze patch (20 cm² bearing 0.5 ml of the test substance was applied to the flank. A control gauze patch was applied to the contralateral flank. The patches were loosely covered with an aluminum foil (36 cm² and held in place for 4 hours by an adhesive tape (Isoplast, Isoplast AG, CH-5200 Bruggl). The animals were checked daily for systemic symptoms and mortality.
SCORING SYSTEM:
The skin reactions were evaluated 1, 24, 48, and 72 hours after removing the gauze patches according to the OECD scoring system.

- Executive summary:
A study was performed to determine the skin irritation of FAT 36152/B in rabbits according to OECD Guideline 404 (Acute Dermal Irritation / Corrosion).
The test was performed on 3 female rabbits, checked for normal skin conditions. An area of at least 6 cm'was shaved on both flanks of the animals approximately 24 hours before treatment. A gauze patch (20 cm² bearing 0.5 ml of the test substance was applied to the flank. A control gauze patch was applied to the contralateral flank. The skin reactions were evaluated 1, 24, 48, and 72 hours after removing the gauze patches according to the OECD scoring system. The application site was blue-stained in some animals up to 72 hours after the application; therefore the evaluation of a possible erythema formation was impeded. Since distinct erythema reactions do not occur without edema reactions FAT 36152/B can be classified as non-irritant in albino rabbits. Under the experimental conditions employed, FAT 36152/B can be classified as non-irritant according to the EEC directive No. 83/467/1983.

Quality Criteria
The relative mean tissue viability for the positive control treated tissues was 2.4 % relative to the negative control treated tissues following the 3-minute exposure period. The positive control acceptance criterion was therefore satisfied. The mean OD562 for the negative control treated tissues was 2.004 for the 3-minute exposure period and 2.005 for the 60-Minute exposure period. The negative control acceptance criteria were therefore satisfied.

Additional information
Skin:
The corrosivity potential of the test item was evaluated using the EpiDerm™ Human Skin Model after treatment periods of 3 and 60 minutes. Duplicate tissues were treated with the test item for exposure periods of 3 and 60 minutes. At the end of the exposure period the test item was rinsed from each tissue before the tissues were taken for MTT-loading. After MTT loading each tissue was placed in 2 mL Isopropanol for MTT extraction. At the end of the formazan extraction period each well was mixed thoroughly and triplicate 200 mL samples were transferred to the appropriate wells of a pre-labeled 96-well plate. The optical density (OD) was measured at 562 nm (OD562). The relative mean viabilities of the test item treated tissues were as follows:
60 minute exposure: 105.8 %
3 minute exposure: 108.8 %
Based on these findings, the test item was considered to be non-corrosive to the skin.
Further, in vivo studies performed according to OECD Guideline 404 with FAT 36152/A (1983) and FAT 36152/B (1986) found the target chemical did not induce irritation on shaven rabbit skin. Hence based on the available data, it can be concluded that the substance under evaluation is not irritating to the skin.
Eye:
A bovine corneal opacity test was performed to identify if the target chemical requires classification for eye irritation or serious eye damage. In this study, the test item was applied at a concentration of 20 % w/v in 0.9 % w/v sodium chloride solution for 240 minutes. Negative and positive control items were tested concurrently. The two endpoints, decreased light transmission through the cornea (opacity) and increased passage of sodium fluorescein dye through the cornea (permeability) were combined in an empirically derived formula to generate an In Vitro Irritancy Score (IVIS). Following treatment, In Vitro Irritancy Score for the test item was determined to be 0.2. Hence, FAT 36152/N can be classified as not irritanting to eyes. In an in vivo study performed according to OECD Guideline 405 (Acute Eye Irritation / Corrosion), 0.1 ml of FAT 36152/B was placed into the conjunctival sac of the right 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 material. The left eye remained untreated and served as a control. The animals were checked daily for systemic symptoms and mortality. The ocular reactions were evaluated 1, 24, 48, and 72 hours after the instillation of FAT 36152/B according to the OECD scoring system. A slit-lamp was used to facilitate the evaluation. The irritant/corrosive potency of FAT 36152/B was classified according to the EEC commission directive No. 83/467, 1983. Because no reactions were observed at 24, 48 and 72 hours after instillation of FAT 36152/B, the test was ended after the 72 hours evaluation and FAT 36152/B was considered as non-irritant to albino rabbit's eye. FAT 36152/A was considered as not irritating when instilled in rabbit eyes (1983). Hence, based on the available data, it was concluded that the substance under evaluation is not irritating to the eyes.
Justification for classification or non-classification
Based on the above stated assessment of the skin as well as eye irritation potential, the substance does not have to be classified for skin or eye irritation according to CLP (Regulation (EC) No 1272/2008 Of the European parliament and of the Council.
