Executive summary:

The skin irritation potential of the test chemical was assessed based on the available results from the various test chemicals.

The dermal irritation potential of the test chemical was assessed in rabbits.0.5 ml of semi permanent dye containing 0.38% (wt/wt) test chemical was applied to the intact skin of 6 rabbits and observed for signs of irritation. The dermal reactions were observed and scored at 24 and 72 hours. The maximum score for dermal reactions was 4.

No signs of irritation were noted on the rabbit skin. The primary irritation index was reported to be 0.0.

Based on the scores and observations, the test chemical can be considered not irritating to rabbit skin.

This is supported by the results of a study performed on rabbits in accordance with OECD 404 Guidelines to determine the degree of irritation caused by the test chemical. The study was performed One day prior to the application of the test chemical, the dorsal area of the trunk of 3 female New Zealand White rabbits was clipped free of fur. 500 mg of the test chemical was moistened with water was applied clipped skin of 3 rabbits under semi-occlusive conditions for 4 hours. Subsequently, the dressings were removed, any residual test substance was wiped off. The skin was examined for erythema, eschar formation and edema at 1, 24, 48 and 72 hours after removal of the patches.

No signs of irritation were noted on the rabbit skin.Brown/yellow skin discolouration was observed at the 1-hour time-point but did not prevent the accurate assessment of erythema.

Based on the observations, the test chemical can be considered not irritating to rabbit skin.

The above studies are supported by the results of a study performed on rabbits in accordance with OECD 404 and 92/69/EEC. Annex V Guidelines to assess the dermal irritation potential of the test chemical was assessed in rabbits. 0.5 g of the test chemical moistened with water was applied to 6.25 cm² area of intact skin of 3 female New Zealand albino rabbits under semi-occlusive conditions for 4 hours. Remaining test substance was removed by swabbing with cotton wool swabs soaked in warm water.The skin was examined for erythema, eschar formation and edema at 1, 24, 48 and 72 hours after removal of the patches. An index of Cutaneous Primary Irritation was calculated from the mean scores at the sites and at each time point. No signs of irritation were noted on the rabbit skin. Red/orange staining was reported at all time points. The primary irritation index was reported to be 0.0.

Based on the scores and observations, test chemical can be considered not irritating to rabbit skin.

By applying the weight of evidence approach, the test chemical can be considered to be not irritating to skin. Comparing the annotations with criteria of CLP regulation, the test chemical can be classified under the category "Not Classified".

Executive summary:

The eye irritation potential of the test chemical was assessed based on the available results from the various test chemicals.

The ocular irritation potential of the test chemical was assessed in rabbits. 100 mg of the powdered dye was instilled in one eye of 6 rabbits and the other eye served as control. The treated eyes were observed and scored at 1, 2, 3, and 7 days. The maximum attainable score was 110.

No signs of irritation were observed in the treated eyes of rabbits at any time point.

The scores obtained at 1, 2, 3, and 7 days were 0.0. Hence, the test chemical can be considered to be not irritating to rabbit eyes.

This is supported by the results of an ocular irritation study of the test chemical conducted on rabbits to assess the eye irritancy of test chemical.

Undiluted 100mg of test chemical was installed into the eye of each rabbits which produced Slight conjunctival changes only after one hour.

Since the observed effects were cleared, the test chemical was considered to be not irritating to the rabbits’ eye.

By applying the weight of evidence approach, the test chemical can be considered to be not irritating to eyes. Comparing the annotations with criteria of CLP regulation, the test chemical can be classified under the category "Not Classified".
