Interpretation of results:
GHS criteria not met
Conclusions:

Executive summary:

This study was performed according to GLP and methods applied are fully compliant with OECD guideline 404.To test the primary skin irritation, 0.5 g of the test material was mixed with some drops of Aqua pro injectione to ensure good contact with the skin. Afterwards, the test material was spread onto 6 cm^2 patches and applied to the intact skin of previously shaven rabbits for a 4 hours period under semiocclusive conditions. The study was started as an initial test with one animal and followed by the confirmatory test with 2 further animals. The first examination of the treated skin sites followed 1 hour after removal of the patches. Thereafter, examinations were performed daily for further 7 days. 24/48/72 hour irritation scores for both erythema and edema were 0 for all animals. Body weight development of the treated rabbits was inconspicuous. Thus, under the conditions of the present study, no signs of irritation were seen.

In this in vivo eye irritation study according to OECD guideline 405, the test item showed no relevant eye irritating potential.
Executive summary:

The study was performed according to OECD guideline 405 under GLP conditions. The test item was tested for its eye irritating properties. Prior to testing, the hen's egg test on the chorioallantoic membrane was performed and no irritating potential could be detected. The test for primary eye irritation was performed initially with one animal and followed by the confirmatory test with two further animals. For the test of primary eye irritation, the test material was applied into the conjunctival sac of rabbits. The first examination of the eyes followed 1 hour after instillation. The other examinations of the eyes were performed daily for a further 7 days. No signs of irritation were observed at the cornea or iris. The conjunctivae showed redness (score 1) at the first reading (1 hour) in all animals and in one animal at the second reading (24 hours). Thereafter no signs of irritation were observed. No abnormalities were detected in the untreated eyes. No relevant eye irritating potential could be detected. The test item should not be classified as an eye irritant.

This study was performed according to GLP and methods applied are fully compliant with OECD guideline 404.To test the primary skin irritation, 0.5 g of the test material was mixed with some drops of Aqua pro injectione to ensure good contact with the skin. Afterwards, the test material was spread onto 6 cm^2 patches and applied to the intact skin of previously shaven rabbits for a 4 hours period under semiocclusive conditions. The study was started as an initial test with one animal and followed by the confirmatory test with 2 further animals. The first examination of the treated skin sites followed 1 hour after removal of the patches. Thereafter, examinations were performed daily for further 7 days. 24/48/72 hour irritation scores for both erythema and edema were 0 for all animals. Body weight development of the treated rabbits was inconspicuous. Thus, under the conditions of the present study, no signs of irritation were seen.

Justification for classification or non-classification

Classification, Labeling, and Packaging Regulation (EC) No 1272/2008


The available data for skin and eye irritation are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. The test item is not considered to be classified for skin and eye irritation/corrosion according to EU Regulation (EC) No 1272/2008 (CLP), as amended for fifteenth time in Regulation (EU) No 2020/217.
