- SCORING SYSTEM: Numerical system according to Draize
TOOL USED TO ASSESS SCORE: Examination of the eye was facilitated by the use of the light source from a standard ophthalmoscope.

- Executive summary:
Introduction
The study was performed in accordance with OECD Guideline No. 405 to assess the irritancy potential of the test item to the eye of the New Zealand White rabbit.
Method
A volume of 0.1 mL of the test item was placed into the conjunctival sac of the right eye, formed by gently pulling the lower li d away from the eyeball. The upper and lower eyelids were held together for about one second immediately after treatment, to prevent loss of the test item, and then released. The left eye remained untreated and was used for control purposes. Immediately after administration of the test item, an assessment of the initial pain reaction was made . Eight hours after test item application, a subcutaneous injection of post-dose analgesia, buprenorphine 0.01 mg/kg and meloxicam 0.5 mg/kg, was administered to provide a continued therapeutic level of systemic analgesia. The treated animal was checked for signs of pain and suffering approximately 0.5 hours later. No further analgesia was required. After consideration of the ocular responses produced in the first treated animal, a second animal was similarly treated. Assessment of ocular damage/irritation was made approximately 1 hour and 24, 48 and 72 hours following treatment, according to the numerical evaluation (Draize, J.H, 1977).
Results
A single application of the test item to the non-irrigated eye of two rabbits produced minimal conjunctival irritation. Both treated eyes appeared normal at the 72-Hour observation.
Conclusion
The test item produced a maximum group mean score of 6.0. The test material is not an irritant in the eye of rabbits. The test item is not classifiable under CLP.
