Irritant / corrosive response data:
Reversibility of any observed effect: Changes fully reversible within 15 days.
Other effects:
Instillation of approximately 40 mg substance into one eye of each of three rabbits resulted in irritation of the conjunctivae, which consisted of redness, chemosis and discharge. The irritation had completely resolved within 7 days in one animal and within 15 days in the other two animals.
No iridic irritation or corneal opacity were observed, and treatment of the eyes with 2% fluorescein, 24 hours after test substance instillation revealed no corneal epithelial damage in any of the animals.
There was no evidence of ocular corrosion.
Remnants of the test substance were present in the eyes of all animals up to 24 - 48 h after instillation. The test substance could only partly be removed by rinsing the treated eyes immediately after the 24 h observation.
No symptoms of systemic toxicity were observed in the animals during the test period and no mortality occurred.
Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
When instillated into eyes of rabbits, the test substance caused irritation of conjunctivae, chemosis and discharge but the irritation completely resolved in 15 days and no iridic irritation or corneal opacitiy were observed.
Executive summary:

A eye irritation test was performed according to 92/69/EWG, B.5. 40 mg of the test substance was instillated into one eye of each three rabbits. The instillationr resulted in irritation of the conjunctivae, which consisted of redness, chemosis and discharge. The irritation had completely resolved within 7 days in one animal and within 15 days in the other two animals. No iridic irritation or corneal opacity were observed, and treatment of the eyes with 2% fluorescein, 24 hours after test substance instillation revealed no corneal epithelial damage in any of the animals.There was no evidence of ocular corrosion.

Remnants of the test substance were present in the eyes of all animals up to 24 - 48 h after instillation. The test substance could only partly be removed by rinsing the treated eyes immediately after the 24-h observation.

No symptoms of systemic toxicity were observed in the animals during the test period and no mortality occurred.

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not irritating)

Justification for selection of skin irritation / corrosion endpoint:
Only one study available.

Justification for selection of eye irritation endpoint:
Only one study available.

Justification for classification or non-classification

Based on available information, the substance is not classified for irritation/corrosion according to CLP Regulation (EU) No 1272/2008.
