Irritant / corrosive response data:
At the first observation, 1 hour after the application, erythema was not assessable due to marked red staining by the test item. This staining persisted as a light staining until the end of the 14 day observation period. No irritant or corrosive effects were noted on the treated skin of any animal at any of the measuring intervals (all scores for erythema or edema = 0) and no clinical signs were observed.
Other effects:
no other effects observed
Interpretation of results:
GHS criteria not met
Conclusions:
The test item did not reveal any irritation potential on the skin of rabbits, tested in this study according to OECD test guideline no. 404 and GLP conditions.
Executive summary:

The primary skin irritation potential of the test item was investigated according to OECD test guideline no. 404. The test item was applied by topical semi-occlusive application of 0.5 g to the intact left flank of each of three young adult New Zealand White rabbits. The duration of treatment was four hours. The scoring of skin reactions was performed 1, 24, 48 and 72 hours, as well as 7, 10 and 14 days after removal of the dressing. The mean score was calculated across 3 scoring times (24, 48 and 72 hours after patch removal) for each animal for erythema/eschar grades and for oedema grades, separately. The test item did not elicit any skin reactions at the application site of any animal at any of the observation times (all scores 0). The individual mean score for erythema/eschar and oedema for each of the three animals was therefore 0. At the first observation, 1 hour after the application, erythema was not assessable due to marked red staining by the test item. This staining persisted as a light staining until the end of the 14 day observation period. No irritant or corrosive effects were noted on the treated skin of any animal at any of the measuring intervals and no clinical signs were observed.

Irritant / corrosive response data:
The mean score was calculated across 3 scoring times (24, 48 and72 hours after instillation) for each animal for corneal opacity, iris,redness and chemosis of the conjunctivae, separately. The individual mean scores for corneal opacity were 0.33, 0.00 and 0.00 and for the iris 0.00 for all three animals. The individual mean scores for the conjunctivae were 0.67, 1.00 and 1.00 for reddening, respectively, and 0.00 for chemosis for each of the three animals.
A very slight corneal opacity affecting the whole area was noted in all treated animals 1 hour after the test item instillation and was still present in one animal at the 24 -hour reading. No abnormal findings were observed in the iris of any animal at any of the measurement intervals.
Moderate reddening of the conjunctivae was noted in all animals at the 1 -hour reading. 24 hours after instillation the reddening was still moderate in one animal and slight in two animals. Slight reddening was noted in two animals at the 48- and 72-hour readings.
Reddening of the sclerae was moderate in one animal and slight in two animals 1 hour after instillation. Slight reddening of the sclerae was observed in all animals at the 24-hour reading and was still present in two animals 48 and 72 hours after the treatment.
Slight ocular discharge was observed in all treated animals 1 hour after the instillation and was still present in two animals 24 hours after the test item instillation.
No abnormal findings were observed in the treated eye of anyanimal 7 days after treatment, the end of the observation period for all animals.
Other effects:
No clinical signs of systemic toxicity were observed in the animals during the study and no mortality occurred.
Interpretation of results:
GHS criteria not met
Conclusions:
The test item did not induce significant or irreversible damage to the rabbit eye in this study according to OECD test guideline no. 405 and GLP conditions.
Executive summary:

The eye irritating potential of the test item was assessed according to OECD TG 405. Three rabbits were exposed to 0.1 mg test item. The mean score was calculated across 3 scoring times (24, 48 and72 hours after instillation) for each animal for corneal opacity, iris,redness and chemosis of the conjunctivae, separately. The individual mean scores for corneal opacity were 0.33, 0.00 and 0.00 and for the iris 0.00 for all three animals. The individual mean scores for the conjunctivae were 0.67, 1.00 and 1.00 for reddening,respectively, and 0.00 for chemosis for each of the three animals.

A very slight corneal opacity affecting the whole area was noted in all treated animals 1 hour after the test item instillation and was still present in one animal at the 24 -hour reading. No abnormal findings were observed in the iris of any animal at any of the measurement intervals.

Moderate reddening of the conjunctivae was noted in all animals at the 1 -hour reading. 24 hours after instillation the reddening was still moderate in one animal and slight in two animals. Slight reddening was noted in two animals at the 48- and 72-hour readings.

Reddening of the sclerae was moderate in one animal and slight in two animals 1 hour after instillation. Slight reddening of the sclerae was observed in all animals at the 24-hour reading and was still present in two animals 48 and 72 hours after the treatment.

Slight ocular discharge was observed in all treated animals 1 hour after the instillation and was still present in two animals 24 hours after the test item instillation.

No abnormal findings were observed in the treated eye of anyanimal 7 days after treatment, the end of the observation period for all animals.
