- Executive summary:
The study was performed acc. OECD TG 404 on 3 New Zealand white rabbits. 0.5 g of the test item was applied neat for 4 h under a semi-occlusive coverage on the clipped skin. After washing, scoring was performed as inidcated in the guideline. Application of the test item to rabbit skin for four hours under a semi- occlusive patch produced no observable skin irritation. Both edema and erythema scores were in all three animal zero, so classification as skin irritant is not required under Regulation 1272/2008.

Corneal opacities (grade 4) developed on all three animals one hour after instillation, and were still present 4 days later. An ulcerated area was seen on the cornea of one animal (No. 434M) the day after instillation.
Iridial inflammation (grade 1) was observed in all three animals.
A beefy-red colouration of the conjuctivae accompanied by considerable swelling and partial closure of the eyelids was seen in all three animals. Blanching and necrosis on tlie eyelids and nictitating membrane accompanied by a copious discharge was seen in all three animals. - Interpretation of results:

According to Regulation 1272/2008 and amendments, 3.3.2.6. Irreversible effects on the eye/serious damage to eyes (Category 1)
3.3.2.6.1. Substances that have the potential to seriously damage the eyes are classified in Category 1 (irreversible effects on the eye). Substances are classified in this hazard category on the basis of the results of animal testing, in accordance with the criteria listed in Table 3.3.1. These observations include animals with grade 4 cornea lesions and other severe reactions (e.g., destruction of cornea) observed at any time during the test,…
Further, according to Table 3.3.1, Category for irreversible eye effects, a substance must be classified as such if, when applied to the eye of an animal, a substance produces: — at least in one animal effects on the cornea, iris or conjunctiva that are not expected to reverse or have not fully reversed within an observation period of normally 21 days; and/ or — at least in 2 of 3 tested animals, a positive response of: — corneal opacity ≥ 3 and/or — iritis > 1,5 calculated as the mean scores following grading at 24, 48 and 72 hours after installation of the test material. This is the case here. Instillation of the test item into the rabbit eye elicited a positive response in all three animals according to OECD test criteria.
Corneal opacification (grade 4), iritis (grade 1) and moderate to severe conjunctival reactions were observed in all three animals. The animals were killed four days after instillation, due to the severity of the reactions.
In consequence, the test item must be classified as Eye dam. Cat. 1. - Executive summary:
The study was performed acc. OECD TG 405 on 3 New Zealand white rabbits. An 87 mg amount of the test item, the weight occupying a volume of 0.1 ml, was placed into the lower everted lid of one eye of each animal. The eyelids were then gently held together for one second before releasing. The contralateral eye remained untreated and served as a control.
Instillation of the test item into the rabbit eye elicited a positive response in. all three animals according to OECD test criteria. Corneal opacification (grade 4), iritis (grade 1) and moderate to ) severe conjunctival reactions were observed in all three animals. The animals were killed four days after instillation, due to the severity of the reactions. In consequence, the test item must be classified as Eye dam. Cat. 1 acc. Regulation 1272/2008 and amendments.

Additional information
Justification for classification or non-classification
For skin irritation, the scoring data was gained according to OECD TG 404, which allows a proper classification. Both edema and erythema scores were in all three animal zero, so classification as skin irritant is not required under GHS.
Regarding eye irritation, Corneal opacification (grade 4), iritis (grade 1) and moderate to severe conjunctival reactions were observed in all three animals. The animals were killed four days after instillation, due to the severity of the reactions.
In consequence, the test item must be classified as Eye dam. Cat. 1.
