Description of key information
Skin irritation/corrosion:
In-vivo:
A key study was performed to determine the acute dermal irritation/corrosion potential of FAT 36156/A on New Zealand rabbits according to the OECD guideline 404.Three female rabbits were used in the test; 0.5 g of the test item was applied to the skin of the rabbit which was shaved not less than 24 hours before the application. The exposure duration was 4 hours. After removal of the dressing the skin reaction was assessed (for erythema and oedema) after 1, 24, 48, 72 hours and during the 7 days of observation period. The animals showed a normal body weight development. Due to intensive blue staining by the test substance a scoring of the erythema values was not possible.The dermal irritation was evaluated after the score for oedema formation only. The calculated dermal irritation index was 1.33 for oedema. Under the conditions of the present experiment FAT 36156/A was found to be slightly skin irritant and not corrosive when applied to the rabbit skin. The calculated dermal irritation index was 1.33 for oedema. The animals had recovered at the end of the observation period of 7 days as well as no systemic effects were noted in the animals during the course of the study. Based on the finding in the skin irritation studies, the test substance can be considered to be not irritant to rabbit skin.
In-vitro:
In Vitro EPIDERM™ Skin Corrosion Test (EPI-200-SCT) was carried out with FAT 36156/D according to OECD 431 and EU method B.40. The purpose of this test is to evaluate the corrosivity potential of the test item using the EpiDerm™ Human Skin Model after treatment periods of 3 and 60 minutes.The relative mean viabilities of the test item treated tissues for 60-minute exposure and 3 minute exposure was 94.3 % and 101.0 %, respectively. Based on the study results, the test item was considered to be non-corrosive to the skin.
Eye Irritation/corrosion:
In-vitro:
The purpose of Bovine Corneal Opacity and Permeability (BCOP) was to identify test items that can induce serious eye damage and to identify test items not requiring classification for eye irritation or serious eye damage. The BCOP test method is an organotypic model that provides short-term maintenance of normal physiological and biochemical function of the bovine cornea in vitro. In this test method, damage by the test item is assessed by quantitative measurements of changes in corneal opacity and permeability. The test was carried out in cattle eyes with FAT 36156/D according to OECD guideline 437 and EU method B.47. Based on the study results, thein vitroirritancy score was 7.7 for FAT 36156/D while 1.4 and 73.6 for negative and positive control respectively. So in conclusion, no prediction of eye irritation can be made.
In-Vivo:
The experiment was performed to determine the potential of FAT 36156/A to induce irritation/corrosion in New Zealand White rabbits according to the OECD Guideline 405. Three male rabbits were used in this study. 0.1 g of the test item 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 held together for about on second in order to prevent the loss of the test material.The left eye remained untreated and served as the control. The ocular reaction was examined 1, 24, 48 and 72 hours after substance instillation.The test was finished after 3 observations days. The animals showed a normal body weight gain.Two animals showed conjunctival redness of score 1 at 24 h observation period which was reversed at 48 h observation period. No other reactions to treatment were recorded during the whole observation period.
Based on the findings of the study, FAT 36'156/A is considered as non-irritant when applied to the rabbit eye. The bovine corneal opacity test could not be used for prediction owing to the IVIS of 7.7, however, using the findings of the in vivo irritation study, Disperse Blue 165:1 can be said to be not irritating to the eyes.

- Executive summary:
In Vitro EPIDERM™ Skin Corrosion Test (EPI-200-SCT) was carried out with FAT 36156/D according to OECD 431 and EU method B.40.The purpose of this test is to evaluate the corrosivity potential of the test item 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 each tissue was 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 200mL 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 relative mean viabilities of the test item treated tissues for 60-minute exposure and 3 minute exposure was 94.3 % and 101.0 %, respectively. Based on the study results, the test item was considered to be non-corrosive to the skin.

Direct MTT Reduction
The MTT solution containing the test item did not turn blue. This was taken to indicate the test item did not reduce MTT.
Assessment of Color Interference with the MTT endpoint
An assessment found that the colored test item may interfere with the MTT endpoint. Therefore, an additional procedure using viable color correction tissues was performed to measure any potential interference. However, the results obtained showed that negligible interference due to the color of the test item occurred. It was therefore considered unnecessary to use the results of the color correction tissues for quantitative correction of results or for reporting purposes.
Quality Criteria
The mean OD562 for the negative control treated tissues was 2.157 for the 3 Minute exposure period and 2.157 for the 60 Minute exposure period. The negative control acceptance criteria were therefore satisfied.
The relative mean tissue viability for the positive control treated tissues was 4.0% relative to the negative control following the 60 Minute exposure period. The positive control acceptance criterion was therefore satisfied.
In the range 20-100% viability the Coefficient of Variation between the two tissue replicates of each treatment group did not exceed 30%. The acceptance criterion was therefore satisfied.

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: room temperature in the dark - Species:
- cattle
- Strain:
- not specified
- Remarks:
- Eyes from adult cattle
- Details on test animals or tissues and environmental conditions:
- Eyes from adult cattle (typically 12 to 60 months old) were obtained from a local abattoir as a by-product from freshly slaughtered animals. The eyes were excised by an abattoir employee after slaughter, and were placed in Hanks’ Balanced Salt Solution (HBSS) supplemented with antibiotics (penicillin at 100 IU/mL and streptomycin at 100 μg/mL). They were transported to the test facility over ice packs on the same day of slaughter. The corneas were refrigerated on arrival and used within 24 hours of receipt.
- Vehicle:
- other: sodium chloride
- Controls:
- yes
- Amount / concentration applied:
- The EMEM was removed from the anterior chamber of the BCOP holder and 0.75 mL of the test item preparation or control items were applied to the appropriate corneas. The holders were gently tilted back and forth to ensure a uniform application of the item over the entire cornea. Each holder was incubated, anterior chamber uppermost, at 32 ± 1 ºC for 240 minutes.
- Duration of post- treatment incubation (in vitro):

- Positive controls validity:
- valid
- Other effects / acceptance of results:
- The corneas treated with the test item or negative control item were clear post treatment. The corneas treated with the positive control item were cloudy post treatment.
Criteria for an Acceptable Test:
The positive control In Vitro Irritancy Score was within the range of 66.9 to 101.4. The positive control acceptance criterion was therefore satisfied. The negative control gave opacity of ≤4.1 and permeability ≤0.105. The negative control acceptance criteria were therefore satisfied. - Interpretation of results:
- study cannot be used for classification
- Conclusions:
- Based on the in vitro irritation score (IVIS) of 7.7, no prediction for FAT 36156/D can be made.
- Executive summary:
The purpose of Bovine Corneal Opacity and Permeability (BCOP) was to identify test items that can induce serious eye damage and to identify test items not requiring classification for eye irritation or serious eye damage. The BCOP test method is an organotypic model that provides short-term maintenance of normal physiological and biochemical function of the bovine cornea in vitro. In this test method, damage by the test item is assessed by quantitative measurements of changes in corneal opacity and permeability. The test was carried out in cattle eyes with FAT 36156/D according to OECD guideline 437 and EU method B.47.
The Eagle’s Minimum Essential Medium was removed from the anterior chamber of the BCOP holder and 0.75 mL of the test item preparation or control items were applied (20 % w/v in 0.9 % w/v sodium chloride solution) to the appropriate corneas. The holders were gently tilted back and forth to ensure a uniform application of the item over the entire cornea. Each holder was incubated, anterior chamber uppermost, at 32 ± 1 ºC for 240 minutes. At the end of the exposure period the test item and control items were removed from the anterior chamber and the cornea was rinsed three times with fresh complete EMEM containing phenol red before a final rinse with complete EMEM without phenol red. The anterior chamber was refilled with fresh complete EMEM without phenol red. A post-treatment opacity reading was taken and each cornea was visually observed. Results from the two test method endpoints, opacity and permeability, were combined in an empirically derived formula to generate an in vitro Irritancy Score. Opacity and Permeability Measurement was made. The condition of the cornea was visually assessed post treatment. 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).
Based on the study results, the in vitro irritancy score was 7.7 for FAT 36156/D while 1.4 and 73.6 for negative and positive control respectively. So in conclusion, no prediction of eye irritation can be made.
