- TEST SITE & APPLICATION
- An area of at least 6 cm² was shaved on both flanks of the animals approximately 24 h before treatment. A gauze patch (20 cm²) bearing 500 mg of the test substance was applied to the flank. A control gauze patch was applied to the contralateral flank. Both gauze patches were moistened before application with distilled water. The patches were loosely covered with an aluminum foil (36 cm² ) and held in place for 4 h by an adhesive tape (Isoplast, Isoplast AG, CH-5200 Brugg).
OBSERVATION: The animals were checked daily for systemic symptoms and mortality. The body weight was recorded at start and on Day 3 of the test.
SCORING SYSTEM: The skin reactions were evaluated 1, 24, 48, and 72 hours after removing the gauze patches according to the OECD scoring system. - Irritation parameter:

- Executive summary:
A study was performed to assess the skin irritation potential of FAT 40045/C (of 100 % purity) in New Zealand White rabbits according to OECD Guideline 404. 500 mg of test substance was applied to a shaved skin area of 6 cm² on one flank of each animal under a 20 cm² gauze pad. The pad was allowed to remain in contact with the skin for 4 h. Animals were scored for irritation reactions after 1, 24, 48 and 72 h. FAT 40045/C induced slight erythema reactions when applied to the clipped albino rabbit skin. The reactions were observed only one hour after removing the bandages. No signs of body weight variability, toxicity or mortality were observed in any animal. Based on these findings, the test substance was considered to be not irritating to skin.

- Executive summary:
A study was conducted to assess the eye irritancy potential of the test substance (of 100 % purity) to the eyes of New Zealand White rabbits according to OECD Guideline 405. A single ocular dose of 0.1 mL (49 mg) of test substance was applied into the conjunctival sac of right eye of each animal. The eyelids were then gently held together for one sec before releasing. The untreated eye served as control. Without washing, eyes were scored for irritation reactions at 1, 24, 48 and 72 h and 7 d post-instillation. Instillation of the test substance into the eye elicited mild conjunctival redness and chemosis. However, the mean scores of 24, 48 and 72 h in all the animals were below the threshold of significance (<2) and had resolved within 72 h after instillation. Based on these findings, the test substance was considered to be not irritating to the eye.

Additional information
Skin:
Two in vivo studies, were carried out to evaluate skin irritation/corrosion and eye irritation potency of the test substance following OECD guidelines without GLP. In the most reliable in vivo study, 500 mg of test substance was applied to a shaved skin area of 6 cm² on one flank of each animal under a 20 cm² gauze pad. The pad was allowed to remain in contact with the skin for 4 h. Animals were scored for irritation reactions after 1, 24, 48 and 72 hours. There was no evidence of any dermal reactions or corrosive effect on the skin. Based on these findings, the test substance was considered to be non-irritating to skin. Another study performed in 1974, also supported the conclusion that Reactive blue 72 (FAT 40045) is not irritating to the skin.
Eye:
An in vivo study (1987) was performed according to OECD Guideline 405. A single ocular dose of 0.1 mL (49 mg) of test substance was applied into the conjunctival sac of right eye of each animal. Without washing, eyes were scored for irritation reactions at 1, 24, 48 and 72 hours and on day 7 post-instillation. Instillation of the test substance into the eye elicited mild conjunctival redness and chemosis. However, the mean scores of 24, 48 and 72 h in all the animals were below the threshold of significance (<2) and had resolved within 72 h after instillation. Based on these findings, the test substance was considered to be non-irritant to the eye. Another study performed in 1974, also supported the conclusion that Reactive Blue 72 (FAT 40045) is not irritating to the eyes of rabbits.
Justification for classification or non-classification
Reactive Blue 72 was found to be not irritating to the skin and eyes of rabbits, hence it does not warrant classification as per the Regulation (EC) No. 1272/2008 (CLP).
