Day 1 after application of the test material, five out of the six rabbits (3 with rinsed eyes and 2 with not rinsed eyes) demonstrated signs of eye irritation (redness, chemosis and discharge); one score was reported for each animal for the three parameters. The maximum combined score was 5.
On Day 2, the signs of irritation in four animals were completely resolved. The remaining animal still exhibiting signs of irritation (eyes not rinsed) received a combined score of 3 for redness, chemosis and discharge. These signs were completely resolved by 72 hours post installation of the test material.

Applicant's summary and conclusion
- Interpretation of results:
- other: Not classified in accordance with EU criteria
- Conclusions:
- Under the conditions of this study, the test material was determined not to be an eye irritant to rabbits.
- Executive summary:
The potential of the test material to cause eye irritation or corrosion was investigated following the technique described in the “Appraisal of the Safety of Chemicals in Foods, Drugs and Cosmetics” (1959) of the US Association of Food and Drug Officials (AFDO).
The test material (0.1 mL) was administered into the left eye of 6 New Zealand White rabbits (3 male/3 female). The right eye remained untreated and served as a control. The eyes of the female rabbits were rinsed approximately 30 seconds after administration with lukewarm water.
The reactions were appraised with a slit-lamp after 24 hours and after 2, 3, 4 and 7 days.
No corneal or iridial effects were observed in any rabbit at any time point. Day 1 after application of the test material, five out of the six rabbits (3 with rinsed eyes and 2 with not rinsed eyes) demonstrated signs of eye irritation (redness, chemosis and discharge). On day 2, the signs of irritation in four animals were completely resolved. One remaining animal still exhibited signs of irritation (eyes not rinsed); these signs were completely resolved by 72 hours post installation of the test material.
Under the conditions of this study, the test material was determined not to be an eye irritant to rabbits.
