The duration of treatment was four hours. The scoring of skin reactions was performed 24 and 48 hours, as well as 8 days after removal of the dressing.
The test item did not elicit any skin reactions at the application site at any of the observation times (all scores 0). No clinical signs were observed.
Under the conditions of the present experiment, the test material does not give indication of an irritant property to rabbit skin.

- Executive summary:
In a primary eye irritation test the acute eye irritation or corrosion potential of the test substance was assessed by a single ocular application of 0.1 mL bulk volume (about 75 mg) of the unchanged test substance to each one eye of three Vienna White rabbits according to Fed.

The ocular reactions were assessed approximately 1, 24, 48 and 72 hours as well as 8 days after application.
Slight or moderate conjunctival redness was observed in some animals during the course of the study, while slight to moderate conjunctival chemosis and slight to moderate discharge only were observed in one animal.
The ocular reactions were reversible in all animals within 8 days after application at the latest. The average score (24 to 72 hours) for irritation was calculated to be 0.0 for corneal opacity and for iris, 0.55 for conjunctival redness and 0.16 for chemosis. Discharge was observed in one animal at readings 24 - 48h (score 2) and 72h (score 1). This was reversible within 8 days
Considering the described ocular reactions as well as the average score for irritation, the test item is not irritating to the rabbit eye.

Additional information
There are reliable studies available to assess the potential of the test substance for skin and eye irritation.
Key study: Skin irritation/corrosion
To assess the acute skin irritation or corrosion potential of the test substance in vivo a skin irritation test in Vienna White rabbits similar to OECD guideline 404 was performed (BASF SE, 1981). The test item was applied by topical occlusive application of 0.5 g of the 50% test substance solution to the upper third of the back or flank of each of two rabbits. The duration of treatment was four hours. The scoring of skin reactions was performed 24 and 48 hours, as well as 8 days after removal of the dressing.
The test item did not elicit any skin reactions at the application site at any of the observation times (all scores 0). No clinical signs were observed.
Under the conditions of the present experiment, the test material does not give indication of an irritant property to rabbit skin.
Key study: Eye irritation
In a primary eye irritation test the acute eye irritation or corrosion potential of the test substance was assessed by a single ocular application of 0.1 mL bulk volume (about 75 mg) of the unchanged test substance to each one eye of three Vienna White rabbits according to Fed. Reg. 38, No. 187, which is equivalent to OECD test guideline 405 (BASF SE, 1981). The test item was not washed out. The ocular reactions were assessed approximately 1, 24, 48 and 72 hours as well as 8 after application.
Slight or moderate conjunctival redness was observed in some animals during the course of the study, while slight to moderate conjunctival chemosis and slight to moderate discharge only were observed in one animal.
The ocular reactions were reversible in all animals within 8 days after application at latest. The average score (24 to 72 hours) for irritation was calculated to be 0.0 for corneal opacity and for iris, 0.55 for conjunctival redness and 0.16 for chemosis. Discharge was observed in one animal at readings 24 - 48h (score 2) and 72h (score 1). This was reversible within 8 days
Considering the described ocular reactions as well as the average score for irritation, the test item is not irritating to the rabbit eye.
Justification for classification or non-classification
Classification, Labelling, and Packaging Regulation (EC) No. 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation 1272/2008. A OECD 404 study is available for skin irritation. A study equivalent to OECD 405 is available for eye irritation. In both studies, the scores for the test item treated tissues were below the thresholds for classification as an irritant. As a result, the substance is not considered to be classified for skin or eye irritation under Regulation (EC) No. 1272/2008, as amended for the seventeenth time in Regulation (EC) No. 2021/849.
