Other effects:
No staining of (peri) ocular tissues by the test substance was observed and no test substance remnants were seen. No symptoms of systemic toxicity were observed in the animals during the test period and no mortality occurred.

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
There was no evidence of ocular irritation or corrosion, no staining of the (peri) ocular tissues, and no symptoms of systemic toxicity were observed after instillation of AC-6000 to the eye. Therefore, AC-6000 is not considered irritating/corrosive for the eyes.
Executive summary:

An acute eye irritation GLP study according to OECD guideline 405 was conducted in three male New Zealand White rabbits in order to evaluate the irritation and corrosion effects of AC-6000 on the eyes. In this study 0.1 mL of the test substance was applied to the left eye of the rabbits. No washing was performed. Observations were made 1, 24, 48 and 72 hours after instillation. No irritation of the ocular tissues was noted after instillation of AC-6000. The mean (24, 48 and 72 hours) cornea, iris, conjunctivae and chemosis scores were all 0. Based on these results AC-6000 can be regarded as not irritating to the eyes.
