- Executive summary:
A study was conducted to evaluate the skin irritation potential of the test substance (of 90.7 % purity) in New Zealand White rabbits according to OECD Guideline 404 and EU Method B.4 in compliance with GLP. 500 mg of test substance was applied to a shaved skin area of 10 cm x 15 cm on one flank of each animal under a moistened 2 cm x 3 cm patch. The patch was held in contact with the skin for 4 h. Animals were scored for irritation reactions after 75 minutes, 24, 48 and 72 h, and then 7 d. Animals were monitored daily for viability, mortality and clinical signs. Body weights were recorded pre-test and at study termination. Very slight erythema was observed in all three animals. The erythema had resolved within 72 h in one animal and within 7 days in other animals. Oedema was not observed in any of the animals during the observation period. Yellow staining of the treated skin by the test substance was observed in the three animals during the study. This staining was found to have been reversed by 72 hours in two animals, however it was still present in one animal by the end of observation period of 7 days. The body weights and variability in body weight gain of the animals were considered to be normal. No symptoms of systemic toxicity were observed in the animals during the test period and no mortality occurred. Based on the above findings, the scores obtained does not meet the classification criteria as set by the Regulation (EC) No. 1272/2008. Hence, the test substance was considered to be not irritating to the skin.

Additional information
Skin irritation:
The skin irritation potential of Disperse Yellow 042 was evaluated in a number of studies conducted over the years. The findings of these studies indicate it to be not irritating to the skin. The skin irritation potential of FAT 36014/F (purity: 90.7 %) was evaluated using New Zealand White rabbits according to OECD Guideline 404 and EU Method B.4 in compliance with GLP. Very slight erythema was observed in all three animals. The erythema had resolved within 72 h in one animal and within 7 days in other animals. Oedema was not observed in any of the animals during the observation period. Yellow staining of the treated skin by the test substance was observed in the three animals during the study. This staining was found to have been reversed by 72h in two animals, however, it was still present in one animal by the end of observation period of 7 days. Based on the above findings, the scores obtained does not meet the classification criteria as set by the Regulation (EC) No. 1272/2008. Hence, the test substance was considered to be not irritating to the skin.
The skin irritation potential of FAT 36014/D (purity: 57.4 %) was evaluated in a study conducted according to OECD Guideline 404. Only one animal (1/3) had very slight erythema and very slight edema at 24h, which was reversed by 48h. the remaining two exposed animals had no irritation reactions. Hence, under the conditions of the present experiment, FAT 36014/D was found to be not irritating to the skin.
The skin irritation potential of FAT 36014/C (purity: 40.8 %) to rabbit skin was evaluated in a study conducted using the patch test technique described in the "Appraisal of the Safety of Chemicals in Foods, Drugs and Cosmetics" (1959), the US Association of Food and Drug Officials (AFDO). No erythema or edema was seen with any of the exposed animals. Hence, the primary skin irritation index in this experiment was established to be 0. Based on the above finding, the test material is concluded to have caused no skin irritation to rabbits.
The skin irritation potential of FAT 36014/B (purity: approx. 20 %) was assessed in rabbits in a study conducted according to the patch test technique as 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). No skin reactions were seen at any of the observations. Hence, it was concluded that FAT 36014/B was found to be not irritating when applied to intact or abraded rabbit skin.
The skin irritation potential of FAT 36014/A (purity: approx. 40 %) was assessed using the method given in the "Hazardous Substances Regulations" under the U.S. Federal Hazardous Substances Labelling Act Sect. 191.11 (February 1965). A mild skin reaction present at 24 hours had resolved by 72 hours. The primary irritation score was 1.3. The scores obtained (erythema for intact skin 1.33 at 24h and 0 for 72h, edema was 0 at 24/72h) does not meet the classification criteria as set by the Regulation (EC) No. 1272/2008. Hence, the test substance was considered to be not irritating to the skin.
Eye irritation:
The eye irritation potential of Disperse Yellow 042 was evaluated in a number of studies conducted over the years. The findings of these studies are discussed below.
The eye irritancy potential of the FAT 36014/F (of purity 90.7%) was assessed using New Zealand White rabbits according to OECD Guideline 405 and EU Method B.5 in compliance with GLP. Slight conjunctival irritation was observed, which resolved within 7 d of instillation. Ocular corrosion was not observed in any of the rabbits. Also, no signs of systemic intoxication were seen. Hence, it can be concluded that the test substance is not to be classified as irritating to the skin.
The eye irritation potential of FAT 36014/D (purity: 57.4 %) was assessed in a study conducted according to OECD guidelines 405. There were no irritation reactions seen with cornea and iris of the exposed animals. Mild reactions were seen with conjunctival redness and chemosis after 1 hour of instillation, which was found to have been reversed by 24 h. Based on these findings, FAT 36014/D is not to be classified as irritating to the eyes.
The eye irritation potential of FAT 36014/C (purity: 40.8 %) was assessed in a study conducted according to the method described in the "Appraisal of the Safety of Chemicals in Foods, Drugs and Cosmetics" (1959), the US Association of Food and Drug Officials (AFDO). There was no reaction seen with cornea, iris or conjunctiva. Hence, under the conditions of this experiment, the test material was found to cause no irritation when applied to the rabbit eye mucosa.
A study was conducted to assess the eye irritancy potential of FAT 36014/B (purity: approx. 20 %) in Russian breed rabbits with the procedure 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). FAT 36014/B was found to cause moderate irritation when applied the rabbit eye mucosa. The irritation consisted of corneal opacity, of reflex hyperemia of the iris and of conjunctival reaction. Complete recovery was found in all animals after 8 days. Rinsing the eyes 1 minute following instillation did not change the results. The mean scores obtained for corneal opacity, iris, conjunctival redness and chemosis were 0.83, 0.56, 1.94 and 0.72, respectively. Hence, it was concluded that FAT 36014/B caused slight irritation to the skin.
A study was conducted to assess the eye irritancy potential of FAT 36014/A (purity: approx. 40 %) in New Zealand White rabbits with the procedure set out in the "Hazardous Substances Regulations" under the U.S.A. Federal Hazardous Substances Labelling Act Sect. 191.12 (February 1955), with slight modification. Apart from a slight injection of the conjunctive in three animals all eyes were normal by day six. The mean scores obtained for corneal opacity, iris, conjunctival redness and chemosis were 0.67, 0.11, 1.72 and 1.06, respectively, does not meet the classification criteria as set by the Regulation (EC) No. 1272/2008. Hence, FAT 36014/A is not considered to be irritating to the eyes.
The available studies indicate that Disperse Yellow 042 with increasing purity does not cause irritation to eye. The only exception being FAT 36014/B (purity: approx. 20 %) was found to have some irritation when instilled into the eyes. However, the other batches namely FAT 36014/F (purity: 90.7 %), FAT 36014/D (purity: 57.4 %) and FAT 36014/C (purity: 40.8 %) did not lead to any irritation when introduced in the eyes. FAT 36014/A (purity: approx. 40 %) did cause some irritation, however the threshold scores were not achieved, hence no classification is required. Hence, it can be said that only FAT 36014/B with lowest purity content had some reactions when instilled in the eyes. Taking into consideration the findings of the available studies, the irritation reactions observed with FAT 36014/B can be assumed to have been resulted from the ingredients other than Disperse Yellow 042 and are regarded as not significant. Further, studies with Disperse Yellow 042 with much higher purity content and conducted in compliance with GLP, indicate that the substance is not irritating to the eyes. Based on the above arguments, Disperse Yellow 042 was regarded as not irritating to the eyes.
Justification for classification or non-classification
Disperse Yellow 042 is considered to be not irritating to the skin and eyes, hence it does not warrant classification according to the criteria of Regulation (EC) No. 1272/2008.
