Description of key information
No skin irritating potential of the test item could be detected in a primary skin irritation test in rabbits according to OECD guideline 404. In an in vivo eye irritation study according to OECD guideline 405, the test item showed eye irritating effects and is thus categorized as irritating to the eye “UN GHS Category 2” (reference 7.3.1-1 and 7.3.2-1).

- Executive summary:
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 patches and applied to the intact skin of previously shaven rabbits for 4 hours under semi-occlusive conditions. The study was performed initially with one animal and followed by the confirmatory test with two further animals according to OECD guideline 404. The first examination of the treated skin followed 1 hour after patch removal. Thereafter, examinations were performed daily for a further 7 days. Under the conditions of the present study no signs of irritation were seen.

- Irritant / corrosive response data:

At the iris signs of irritation were observed (score 1) from day 2 up to day 5 in one animal. The conjunctivae showed redness (scores 1 and 2) from the first investigation up to day 6 and 7. Chemosis (score 1 and 2) was seen up to experimental day 4. Furthermore, discharge was observed 1 hour after instillation of the test material up to day 4 of the experimental part (scores 1 and 4). The untreated eye was unchanged.
- Other effects:
- - Lesions and clinical observations: No signs of pain were observed immediately after instillation.
- Interpretation of results:
- Category 2 (irritating to eyes) based on GHS criteria
- Conclusions:
- In this in vivo eye irritation study according to OECD guideline 405, the test item showed eye irritating effects and is thus categorized as irritating to the eye “UN GHS Category 2”.
- Executive summary:
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 one further animal according to OECD guideline 405. 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 14 days. Two rabbits were used in this study. No signs of pain were observed immediately after instillation. Diffuse areas of opacity were seen at the cornea 1 hour after instillation up to day 5 and 7 of the experimental part. The iris showed signs of irritation from day 2 up to day 5 in one animal. The conjunctivae were reddened from the first investigation up to day 6 and 7. Chemosis was observed in both animals up to experimental day 4. The individual scores after 24/48/72 hours were 0 (animal 1) and 2 (animal 2) for iris irritation, 2 (animal 1) and 1 (animal 2) for reddening of the conjunctivae, 1.33 (animal 1) and 1 (animal 2) for chemosis and 1 (animal 1) and 1.33 (animal 2) for corneal opacity. The untreated eyes were unchanged. In conclusion, the test item was considered to be irritating to the eye.

Skin irritation, key study
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 patches and applied to the intact skin of previously shaven rabbits for 4 hours under semi-occlusive conditions. The study was performed initially with one animal and followed by the confirmatory test with two further animals according to OECD guideline 404. The first examination of the treated skin followed 1 hour after patch removal. Thereafter, examinations were performed daily for a further 7 days.

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 irritation/corrosion but for eye irritation (category 2) according to EU Regulation (EC) No 1272/2008 (CLP), as amended for fifteenth time in Regulation (EU) No 2020/217.
