- Irritant / corrosive response data:
- Slight to marked red staining of the treated skin area produced by the colour of the test item was noted in all animals from the 1- to the 48-hour reading and persisted in two animals up to the 72-hour or 7-day reading, respectively.
The grading of the erythema was not possible in all animals at the 1- hour reading because of the staining produced by the test item. At later time points no erythema were detectable (score 0). No edema were visible at any point of time (score 0 at all readings). - Interpretation of results:
- not irritating
- 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 skin irritating potential of the test item was assessed according to OECD TG 404. Three rabbits were exposed to 0.5 mg test item under semi-occlusive conditions. Slight to marked red staining of the treated skin area produced by the colour of the test item was noted in all animals from the 1- to the 48-hour reading and persisted in two animals up to the 72-hour or 7-day reading, respectively.
The grading of the erythema was not possible in all animals at the 1- hour reading because of the staining produced by the test item. When the skin was assessable, 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. No abnormal findings were observed on the treated skin of any animal 10 days after treatment.

- Irritant / corrosive response data:
- The individual mean scores for iris were 0.00 for all three animals. The individual mean scores for corneal opacity were 0.00, 0.00 and 0.33, respectively. The individual mean scores for the conjunctivae were 1.00, 0.33 and 1.00 for reddening and 0.00 for chemosis for all three animals, respectively. No abnormal findings were observed in the iris of any animal at any of the measurement intervals. Very slight corneal opacity affecting the whole area was observed in all animals 1 hour after treatment and persisted in one animal until the 24-hour reading. Slight to moderate reddening of the conjunctivae was noted in all animals at the 1-hour reading and persisted as slight reddening until the 24-, 72-hour or 7-day reading, respectively. Slight swelling of the conjunctivae was noted in one animal at the 1-hour reading. Slight to moderate reddening of the sclerae was present in all animals at the 1-hour reading and persisted as slight reddening until the 48-hour reading in one animal and until the 72- hour reading in two animals. Slight to moderate ocular discharge was noted in all animals 1 hour after treatment and persisted as slight discharge in one animal until the 24-hour reading. No abnormal findings were observed in the treated eye of any animal 10 days after treatment, the end of the observation period in 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 100 mg test item. The mean score was calculated across 3 scoring times (24, 48 and 72 hours after instillation) for each animal for corneal opacity, iris, redness and chemosis of the conjunctivae, separately. The individual mean scores for iris were 0.00 for all three animals. The individual mean scores for corneal opacity were 0.00, 0.00 and 0.33, respectively. The individual mean scores for the conjunctivae were 1.00, 0.33 and 1.00 for reddening and 0.00 for chemosis for all three animals, respectively. No abnormal findings were observed in the iris of any animal at any of the measurement intervals. Very slight corneal opacity affecting the whole area was observed in all animals 1 hour after treatment and persisted in one animal until the 24-hour reading. Slight to moderate reddening of the conjunctivae was noted in all animals at the 1-hour reading and persisted as slight reddening until the 24-, 72-hour or 7-day reading, respectively. Slight swelling of the conjunctivae was noted in one animal at the 1-hour reading. Slight to moderate reddening of the sclerae was present in all animals at the 1-hour reading and persisted as slight reddening until the 48-hour reading in one animal and until the 72- hour reading in two animals. Slight to moderate ocular discharge was noted in all animals 1 hour after treatment and persisted as slight discharge in one animal until the 24-hour reading. No abnormal findings were observed in the treated eye of any animal 10 days after treatment, the end of the observation period in all animals.
