Executive summary:

In order to assess the eye irritating potential of the test substance, 0.1 ml of the undiluted test item was applied into the conjunctival sac of the left eye of each of 3 rabbits. The untreated eye serves as control. After one hour the treated eye was washed. The assessment of possible effects to the eyes was performed with the assistance of a lamp 60 minutes, 24, 48 and 72 hours after application of test item. The eye reactions were assessed according to the numerical scoring system (acc. to Draize). The description of the degree and nature of irritation and the presence of serious damage were noted as follows:

- No mortality or signs of systemic toxicity occurred.

- Hyperemia was observed in two of three animals at the 24 hour time point (score 1 -1 -0). This effect was reversible within 48 hours.

- No Chemosis of the conjunctiva was observed in all animals 24, 48 and 72 hours after application (score 0-0-0).

- No Corneal opacity were observed in all three animals 24, 48 and 72 hours after application of the test substance (score 0-0-0).

- No effects at Iris was observed in all animals 24, 48 and 72 hours after application of the test substance (score 0-0-0).

Under the conditions of this test and the results obtained, it is concluded, that the test substance is not irritant to the eye.
