Number of animals:
6 rabbits (3 males/ 3 females)
Details on study design:
Six rabbits (3 males/3 females) of the Russian breed, weighing 1.5 to 2 kgs,were shaved on the whole back and flanks two days before treatment with an electric clipper. The shaven skin on the left side was slightly scarified immediately before treatment. A gauze patch 2.5 x 2.5 cm was soaked with the test substance (0.5 g) and immediately applied to the prepared skin. Before application a 50 % polyethylene glycol trituration (PEG 400) was made.The patch was covered with a plastic film 5 x 5 cm, which was fixed to the body with adhesive tape. The gauze patches were removed 24 h after the application. The reaction of the skin was appraised upon removal and 72 h after it.

Executive summary:

Test was performed to evaluate irritant effects after single application of FAT 40062/A on rabbit Skin by following patch-test technique described in the "Appraisal of the Safety of Chemicals in Foods, Drugs and Cosmetics" (1959) of the US Association of Food and Drug Officials (AFDO). Primary irritation to the skin is measured by a patch test technique on the abraded and intact skin of the Russian breed rabbits, clipped free of hair. Six rabbits (3 males/3 females) weighing 1.5 to 2 kgs,were shaved on the whole back and flanks two days before treatment with an electric clipper. In order to prevent injuries by bites the rabbits were kept separately in V2A wire cages. The shaven skin on the left side was slightly scarified immediately before treatment by application of 50 % Polyethylene glycol trituration (PEG 400). A gauze patch 2.5 x 2.5 cm was soaked with the test substance (0.5g) and immediately applied to the prepared skin. The patch was covered with a plastic film 5 x 5 cm, which was fixed to the body with adhesive tape. The gauze patches were removed 24 h after the application. The reaction of the skin was appraised upon removal and 72 h after it. The primary irritation index along with erythema and edema to the skin of rabbits was found to be '0'. Therefore, FAT 40062/A is to be considered as non-irritant to the skin of rabbits.

Executive summary:

FAT 40062/A, was evaluated for primary eye irritation after instillation of 0.1 g of the test substance into the conjunctival sac of the left eye of 6 rabbits (3 males/ 3 females) of the Russian breed, which were kept separately in V2A wire mesh cages. After application, the eyelids were held open for a few seconds. The right eye served as a control. Only rabbits showing normal ophthalmic findings were included in the test. The eyes of 3 of these 6 rabbits were rinsed with 10 ml of lukewarm water about 30 seconds after treatment. The treated eyes of all animals (washed and unwashed) were evaluated after 24 h and after 2, 3, 4 and 7 days on the basis of the "Appraisal of the Safety of Chemicals in Foods, Drugs and Cosmetics" (1959) of the AFDO. The primary-irritation index, which serves as a measure of the acute irritation provoked by the substance, was found to be 0 for the cornea, 0 for the iris and 0 for the conjunctivae.

Therefore, FAT 40062/A is to be considered as non-irritant to the eye of rabbits.

Additional information

Skin Irritation:

Test was performed to evaluate irritant effects after single application of FAT 40062/A on rabbit Skin according to "Appraisal of the Safety of Chemicals in Foods, Drugs and Cosmetics" (1959) of the US Association of Food and Drug Officials (AFDO). Primary irritation to the skin is measured by a patch test technique on the abraded and intact skin of the Russian breed rabbits. Six rabbits (3 males/3 females) were shaved on the whole back and flanks two days before treatment with an electric clipper. In order to prevent injuries by bites the rabbits were kept separately in V2A wire cages. The shaven skin on the left side was slightly scarified immediately before treatment by application of 50 % Polyethylene glycol trituration (PEG 400). A gauze patch 2.5 x 2.5 cm was soaked with the test substance (0.5g) and immediately applied to the prepared skin. The patch was covered with a plastic film 5 x 5 cm, which was fixed to the body with adhesive tape.The gauze patches were removed 24 h after the application. The reaction of the skin was appraised upon removal and 72 h after it. The primary irritation index along with erythema and edema to the skin of rabbits was found to be '0'. Therefore, FAT 40062/A is to be considered as non-irritant to the skin of rabbits.

Eye Irritation:

FAT 40062/A, was evaluated for primary eye irritation after instillation of 0.1 g of the test substance into the conjunctival sac of the left eye of 6 rabbits (3 males/ 3 females) of the Russian breed, which were kept separately in V2A wire mesh cages. After application, the eyelids were held open for a few seconds. The right eye served as a control. The eyes of 3 of these 6 rabbits were rinsed with 10 ml of lukewarm water about 30 seconds after treatment. The treated eyes of all animals (washed and unwashed) were evaluated after 24 h and after 2, 3, 4 and 7 days on the basis of the "Appraisal of the Safety of Chemicals in Foods, Drugs and Cosmetics" (1959) of the AFDO. The primary-irritation index, which serves as a measure of the acute irritation provoked by the substance, was found to be '0' for the cornea, '0' for the iris and '0' for the conjunctivae. Therefore, FAT 40062/A is to be considered as non-irritant to the eye of rabbits.

Justification for classification or non-classification

Based on the findings in the skin irritation as well as eye irritation studies, Reactive Red 065 does not considered to be classified according to the EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008 to be irritating to the skin and eye.
