An edema extending beyond the area of exposure with a score of 1 was observed in one animal after 4 hours, reversible within 24 hours. In addition, erythema formation (score = 2) was observed in all animals 4 hours after exposure. The erythema extended beyond the area of exposure in all animals at this observation time point. The severity of erythema decreased during the observation period and was fully reversible in all animals within 8 days. The mean (24/48/72 h) erythema and edema scores were 0.9 and 0, respectively.

No effects in the cornea and iris were observed at any observation time point. The mean scores (24, 48, 72 hours) for conjunctival redness and chemosis were 1.3 and 0.3, respectively. One animal displayed a conjunctival redness of at the end of the observation period with a score of 1 (full reversibility is expected after longer observation). Chemosis was fully reversible within 48 hours.

Additional information
Skin irritation
In a skin irritation study following OECD guideline 404, 500 mg of a 50% aequous preparation of the test substance was applied to the left flanks of three Vienna White rabbits (BASF AG, 1982). The untreated right flan served as control. The animals were observed for 8 days. An edema extending beyond the area of exposure with a score of 1 was observed in one animal after 4 hours, reversible within 24 hours. In addition, erythema formation (score = 2) was observed in all animals 4 hours after exposure. The erythema extended beyond the area of exposure in all animals at this observation time point. The severity of erythema decreased during the observation period and was fully reversible in all animals within 8 days. The mean (24/48/72 h) erythema and edema scores were 0.9 and 0, respectively. Based on the results of this study, the test article caused a mild irritation response below the level of regulatory significance and is therefore considered to be not irritating to the rabbit skin.
Eye irritation
In an eye irritation study following OECD guideline 405, 0.1 ml of the test substance was applied undiluted into the eyes of three Vienna White rabbits (BASF AG, 1982). The test animals were observed for eight days and irritation scores were recorded 1, 24, 48 and 72 hours and 8 days after the instillation. No effects in the cornea and iris were observed at any observation time point. The mean scores (24, 48, 72 hours) for conjunctival redness and chemosis were 1.3 and 0.3, respectively. One animal displayed a conjunctival redness of at the end of the observation period with a score of 1 (full reversibility is expected after longer observation). Chemosis was fully reversible within 48 hours. Based on the results of this study, the test article caused mild ocular reactions below the level of significance and is therefore regarded as not irritating to the rabbit eye.
Further toxicological data of category members:
Reliable data from several studies on irritation are available for the test article and for other members of the "perylene based pigments" category (see attached category justification). All of these data are taken into account for the evaluation and assessment of the irritation potential of the test article. Studies concerning the irritating potential for skin and eyes are available for all category members. In no study evidence for irritating or corrosive effects of the substances was observed. The category members can therefore all considered as not irritating to the skin and eyes.
Justification for classification or non-classification
Classification, Labelling, and Packaging Regulation (EC) No. 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation 1272/2008. An OECD 404 study is available for skin irritation. An OECD 405 study is available for eye irritation. In both studies, the scores for the test item treated tissues were below the thresholds for classification as an irritant. As a result, the substance is not considered to be classified for skin or eye irritation under Regulation (EC) No. 1272/2008, as amended for the fourteenth time in Regulation (EC) No. 2020/217.
