The cutaneous reactions, with the exception of scaling, were reversible in all animals within 7 days after removal of the patch at latest.
The average score (24 to 72 hours) for irritation was calculated to be 1.2 for erythema and 0.0 for edema. - Interpretation of results:
- GHS criteria not met
- Conclusions:
- Considering the described cutaneous reactions as well as the average score for irritation, the test substance shows a slight skin irritation potential below the regulatory threshold under the test conditions chosen.
- Executive summary:
The test article's potential to cause acute dermal irritation or corrosion was assessed by a GLP-compliant study according to OECD guideline 404. An amount of 0.5 g of the test substance was applied topically for 4 hours to the intact skin of three White New Zealand rabbits, using a patch of 2.5 cm x 2.5 cm, covered with semiocclusive dressing. After removal of the patch the application area was washed off. The cutaneous reactions were assessed immediately after removal of the patch, approximately 1, 24, 48 and 72 hours after removal of the patch and on day 7. Slight or moderate erythema was observed in the animals during the course of the study. The application area was slight black discolored in two animals during the observation period. Scaling was noticed in one animal at study termination, only. The cutaneous reactions, with the exception of scaling, were reversible in all animals within 7 days after removal of the patch at latest. The average score (24 to 72 hours) for irritation was calculated to be 1.2 for erythema and 0.0 for edema. Therefore, under the test conditions chosen, the test article is considered to be non irritating according to GHS and EU regulations.

Additional information
Skin irritation
Irritation to skin was analyzed in a GLP-compliant study reliable without restrictions (BASF, 2005). The solid test substance was minimally moistened with a suitable amount of doubly-distilled water (corresponding to a dose of 0.5 g of unchanged test substance). The test substance was administered under semiocclusive conditions to the skin of 3 white A 1077 INRA (SPF) rabbits for 4 h to determine the irritant potential of the test substance. The mean score (24 - 48 -72 h) for erythema was 1. No edema was detected. All erythema were reversible within 7 days. The application area was slight black discolored in two animals during the observation period. Scaling was noticed in one animal at study termination, only. Based on the results of this study, the test substance was found to be not irritating to the rabbit skin.
Eye irritation
Irritation to eyes was analyzed in a GLP Guideline study (OECD 405) which was reliable without restrictions (BASF, 2005). Three white A 1077 INRA (SPF) rabbits received about 16 mg of the comminuted test substance (0.1 ml bulk volume). About 1 hour after application the eye was rinsed with tap water. The ocular reactions were assessed approximately 1, 24, 48 and 72 hours after application. Slight to moderate conjunctival redness, slight conjunctival chemosis and slight discharge were observed in the animais up to 24 hours after application. Two animais showed injected scleral vesseis in a circumscribed area. The ocular reactions were reversible in all animals within 48 hours after application. The average score (24 to 72 hours) for irritation was calculated to be 0.0 for corneal opacity, iris and chemosis and 0.3 for conjunctival redness. Considering the described ocular reactions as weil as the average score for irritation, the test substance did not show an eye irritation potential under the test conditions chosen.
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. A GLP-compliant OECD 404 study is available for skin irritation. A GLP-compliant 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.
