Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The test material was not an eye irritant.
Executive summary:

An ocular irritation test was carried out on test material Cosmacol ECL according to OECD Guideline 405.

The test was performed by placing the test material in a single dose in the conjunctival sac of 6 albino male rabbits at a dose of 0.1 g/animal. The animals eyes were examined 1, 24, 48 and 72 hours after the beginning of the test. The ocular areas obvserved were the cornea, the iris and conjunctivae. The results showed a slight congestion of the conjunctivae in 2 of 6 rabbits treated. This irritation was seen one hour after the treatment, and disappeared 72 hours after treament.

It was concluded that Cosmacol ECL is to be considered non-irritant to eyes.
