Additional information
Skin irritation
No study data with the test item is available for skin irritation. Therefore, a read-across to the read-across substance with a very similar chemical structure and comparable physico-chemical parameters is used to evaluate the skin irritation potential of the test item.
To identify the skin irritation/corrosion potential the read-across substance was applied to the intact skin of three female rabbits for a 4 hours period under semiocclusive conditions. Therefore, the read-across substance was mixed with some drops of Aqua pro injectione to ensure good contact to the skin. After removal of the patches the remaining read-across substance was wiped off. The first examination of the treated skin sites followed 1 hour after removal of the patches. Then, examinations were performed daily for further 7 days. The evaluation of all animals yields a zero mean score for both edema and erythema. Therefore, under the conditions of the study according to OECD 404 no signs of skin irritation were detected.
Eye irritation
No study data with the test item is available for eye irritation. Therefore, a read-across to the read-across substance with a very similar chemical structure and comparable physico-chemical parameters is used to evaluate the eye irritation potential of the test item.
An in vivo study in rabbits according to OECD 405 was conducted to evaluate the eye irritation potential of the read-across substance. Therefore, 0.1 g of the ground read-across substance was applied into the conjunctival sac of the left eye of 3 rabbits while the right untreated eye served as control. The first examination of the eyes followed 1 hour after instillation. The examinations were performed daily for further 7 days. No signs of irritation were observed at the cornea and iris. The conjunctivae showed redness (score 1) 1 hour after application. Afterwards, all scores returned to 0 and the effect was fully reversible within the first 24 hours after treatment. The untreated eyes were unchanged. Based on the observations the read-across substance has not to be regarded as an irritant for the eyes.
Justification for classification or non-classification
Classification, Labeling, and Packaging Regulation (EC) No 1272/2008
The available data for skin irritation/corrosion are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. Based on this data, the substance is considered to be not classified for skin irritation or corrosion under Regulation (EC) No 1272/2008, as amended for the twelfth time in Regulation (EC) 2019/521.
The available data for eye irritation are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. Based on this data, the substance is considered to be not classified for causing serious eye damage or irritation under Regulation (EC) No 1272/2008, as amended for the twelfth time in Regulation (EC) 2019/521.
