Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The substance produced minimal conjunctival irritation when applied into rabbit eye.
- Executive summary:
The potential of the test item to induce eye irritation was assessed in rabbits according to OECD Guideline 404 in compliance with Good Laboratory Practice.
A volume of 0.1 mL of the test substance was placed into the conjunctival sac of the right eye of two New Zealand White rabbits without irrigation. The left eye remained untreated and was used for control purposes. Assessment of ocular damage/irritation was made 1, 24, 48 and 72 hours following treatment according to the Draize scoring method.
No corneal or iridial effects were noted during the study. Minimal conjunctival irritation was seen in both animals 1 and 24 hours after treatment and in one animal at the 48 hour observation. These effects were reversible within 48 hours in one animal and within 72 hours in the other.
It was concluded that the test item produced minimal conjunctival irritation when applied into rabbit eye.
