- PRETESTS:
Prior to testing, the pH of a preparation of the test material was determined with pH test stripes. The pH was found to be approx. 7.
ADMINISTRATION AND DOSE LEVEL
Approx. 24 h before treatment, ophthalmologic examinations were performed using 0.15% fluorescein solution, to ensure that only rabbits with normal eyes were used for the study. Animals with eye defects, injury or irritation were excluded.
0.1 g of the test material was instilled into the conjunctival sac of the left eye of each animal. After instillation the eye lid was closed for approx. 30 seconds.
REMOVAL OF TEST SUBSTANCE
- Washing (if done): the treated eye remained unwashed
SCORING SYSTEM: Draize scoring system. The animals were examined for eye irritation 1 h after tratement, after 24, 48 and 72 hours, and then daily up to day 15 of the experimental part.

- Irritant / corrosive response data:
- No signs of irritation could be observed at the cornea or iris. In animal 1, the conjunctivae showed slight redness at the first and second reading (1 h and 24 h), and slight chemosis at the first reading at 1 h. Further, discharge at the first reading was seen. In animals 2 and 3 similar signs of irritation were seen. The conjunctivae showed slight redness and chemosis at the first reading (1 h). Furthermore, discharge was seen. Thereafter no signs of irritation were observed. The untreated eyes were unchanged.
- Other effects:
- There was no mortality and no signs of toxicity were observed during the study period. The body weight gains were within the normal ranges during the study period.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test item is not irritating to eye.
- Executive summary:
The test item was tested for its eye irritating properties. Prior to testing, the HET-CAM test was performed and no irritating potential could be detected. The test for primary eye irritation was started as an initial test with one animal and followed by the confirmatory test with two further animals.
For the test of primary eye irritation, 0.1 g of 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 were performed daily for further 7 days.
No signs of irritation could be observed at the cornea or iris. The conjunctivae showed redness (score 1) at the first (1 hour) and second reading (24 hours) and only in one animal chemosis (score 1) at the first reading (1 hour). Furthermore, discharge (score 1) at the first reading was seen. Thereafter no signs of irritation were observed. The untreated eyes were unchanged.
Except for a slight reddening, chemosis and discharge of the conjunctivae at the first and second reading (24 hours), which were regarded due to mechanical irritation, no signs of irritation was observed. Therefore, the test item should not be regarded as an irritant to the eyes.
