- Housing: On arrival and following assignment to the study, animals were housed individually in labeled cages with perforated floors (Ebeco, Germany, dimensions 67 x 62 x 55 cm) equipped with water bottles. The room(s) in which the animals were kept were documented in the study records. Each cage was clearly labeled.

In addition, hay (TecniLab-BMI BV, Someren, The Netherlands) was available during the study period. The feed was analyzed by the supplier for nutritional components and environmental contaminants. Results of the analysis were provided by the supplier and are on file at the Test Facility. It is considered that there were no known contaminants in the feed that would interfere with the objectives of the study.
- Water (e.g. ad libitum): Municipal tap-water was freely available to each animal via water bottles. Periodic analysis of the water was performed, and results of these analyses are on file at the Test Facility. It is considered that there were no known contaminants in the water that would interfere with
the objectives of the study.
- Acclimation period: At least 5 days.

- Irritant / corrosive response data:
- Instillation of the test item resulted in irritation of the conjunctivae at the 1 hour examination, which consisted of redness (3/3 animals, scores of 1) and discharge (2/3 animals, scores of 1). The irritation had completely resolved by the 24 hour observation in all animals. No iridial irritation or corneal opacity were observed, and treatment of the eyes with 2% fluorescein 24 hours after test item instillation revealed no corneal epithelial damage. No staining of (peri) ocular tissues by the test item was observed and no test item remnants were seen.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Based on the results of the study, the test article is not an ocular irritant.
- Executive summary:
The acute ocular irritation potential of the test article was evaluated in three male rabbits. The study was conducted according to OECD 405 (2012) in compliance with OECD GLP principles. Each animal was treated by instillation of 0.1 mL of the test article, in the conjunctival sac of one of the eyes after gently pulling the lower lid away from the eyeball while the other eye remained untreated to serve as a reference control. The lids were then gently held together for about one second to prevent loss of the test item. Observations were made 1, 24, 48 and 72 hours after instillation with fluorescein being utilized at the 24 hour observation to quantitatively determine corneal epithelial damage. Instillation of the test item resulted in irritation of the conjunctivae at the 1 hour examination, which consisted of redness (3/3 animals, scores of 1) and discharge (2/3 animals, scores of 1). The irritation had completely resolved by the 24 hour observation in all animals. No iridial irritation or corneal opacity were observed, and treatment of the eyes with 2% fluorescein 24 hours after test item instillation revealed no corneal epithelial damage. No staining of (peri) ocular tissues by the test item was observed and no test item remnants were seen. Based on the results of the study, the test article is not an ocular irritant.
