Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In the eye irritation study, conducted according to OECD Test Guideline 405 and in compliance with GLP, the tes material was concluded to be not irritating to the eyes of three female rabbits when applied for 24 hours.
- Executive summary:
In a GLP-compliant study performed in accordance with OECD Test Guideline 405, the test material was tested for its potential to irritate the eyes of rabbits.
0.1 ml of the test material was applied to the right eyes of three female rabbits for 24 hours, with the left eyes of each animal serving as an untreated control. Animals were observed at 1, 24, 48 and 72 hours after test substance administration using a slit pen light. Fluorescein and UV light were used to aid in the examination of corneal lesions after the 1-hour scoring and/or as long as corneal opacity persisted in individual rabbits.
Following treatment, no adverse effects were seen on the cornea or iris. Conjunctival redness and slight swelling was seen in all animals at the 1-hour reading, with redness persisting in two animals at the 24-hour reading. There were no other significant effects seen over the course of the study, and no mortality was observed.
An overall irritation score of 5.3 was calculated according to the Draize system of scoring (maximum possible Draize score = 110). Under the conditions of this study, the test material was not considered to be an eye irritant in rabbits.
