Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Based on the EU classification criteria Hostapon SG as applied is considered as very mildly irritating to the rabbit eye. All effects were reversible.
- Executive summary:
The test item was tested for primary eye irritation according to OECD 405 and GLP. 0.1 mL of the test item was applied into the left conjunctival sac of 3 rabbits. The right eye served as a control. Assessments were made 1, 24, 48 and 72 hours p.a. as well as 7 days after treatment. No clinical signs of systemic toxicity were observed in the animals during the study and no mortality occurred. The mean score was calculated across 3 scoring times (24, 48 and 72 hours after instillation) for each animal for corneal opacity, iris, redness and chemosis of the conjunctivae, separately. The individual mean scores for corneal opacity and iris were 0.00 for all three animals. The individual mean scores for the conjunctivae were 1.67, 2.00 and 1.67 for reddening and 2.00, 1.33 and 2.00 for chemosis, respectively. Slight to moderate reddening of the conjunctivae was noted in all animals 1 to 72 hours after treatment. Slight to marked swelling of the conjunctivae (chemosis with half-closed lids) was observed in all animals 1 to 72 hours after treatment. Moderate reddening of the sclera was present in one animal 1 to 72 hours after treatment. Due to the marked swelling (with halfclosed lids) of the conjunctivae, the assessment of the sclera was first prevented in two animals. When assessable at the 24-hour reading, a moderate reddening of the sclera was noted. Slight to moderate ocular discharge was recorded in all animals 1 to 72 hours after treatment. No abnormal findings were observed in the treated eye of any animal 7 days after treatment. No corrosion of the cornea was observed at any of the reading times.
