Applicant's summary and conclusion

Interpretation of results:
other: not classified, according to the CLP Regulation (EC 1272/2008)
Conclusions:
Not eye irritating.
Executive summary:

A study was performed to assess the irritation of the test material to the eye of the New Zealand White rabbit (SPL Standard Test Method 560.06). The method followed OECD guideline 405 and method B5 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC). A single application of 0.1 ml (67.3 mg) of the test material was administered to the non irrigated eye of three rabbits. Ocular reactions were observed at 1, 24, 48 and 72 hours after administration.

The Maximum Group Mean Score was 4.1 and the related classification was as mild irritant (class 4 on a 1 -8 SCALE).

Where present, reactions were slight and fully reversible within 72 hours.

Conclusion

The mean values from gradings at 24, 48 and 72 hours were lower than 1 for corneal opacity, lower than 1 for iritis, lower than 2 for both conjunctival redness and oedema, in all of the three tested animals.

Therefore, the substance is not an eye irritant.
