- An area of at least 36cm2 was shaved on both flanks of the animals approximately 24 hours before treatment. A gauze patch (approx. 12-16cm2) bearing 0.5g of the test article was applied to the right flank of each animal. The skin area exposed directly to the test article was approx. 6 cm2. A control gauze patch was applied to the contralateral flank. Before application both patches were moistened with distilled water. The patches were loosely covered with an aluminum foil (approx. 36cm2) and held in place for 4 hours by an adhesive tape (Isoplast, Isoplast AG, CH-5200 Brugg). The animals were checked daily for systemic symptoms and mortality. The skin reactions were evaluated 1, 24, 48, and 72 hours after removing the gauze patches.

- Irritant / corrosive response data:
- - Because of the red staining by the test article the evaluation of possible erythema reactions was impeded up to 72 hours after aplication in all animals. Therefore the mean values 24-72 hours for erythema reactios could not be calculated.
- Slight edema reactions were observed within 72 hours after removing the bandages.
- No signs of skin irritation was observed at the termination of the test on day 7. - Other effects:
- - In 2 animals a slight loss of weight was observed on day 3 of the test.
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the conditions of this experiment, the test substance was found to be not irritating or corrosive.
- Executive summary:
In a GLP compliant skin irritation study, performed according to OECD guideline 404, the test substance (moistened, 0.5g) was applied, semi-occlusive, to the skin of three New Zealand White rabbits for 4 hours. The erythema score could not be determined due to the red color of the test substance. However, after 7 days no erythema was observed. A edema score of 2, 1.67, 1, and 0.66 was observed at 1, 24, 48, 72 hours, respectively. Edema was fully reversible after 7 days. Under the conditions of this experiment, the test substance was found to be not irritating or corrosive.

- Observation period (in vivo):

- Number of animals or in vitro replicates:
- 3 male rabbits
- Details on study design:
- The test substance was placed into the conjunctival sac of the left eye of each animal after gently pulling away the lower lid from the eyeball. The lids were then held together for about one second in order to prevent loss of the test article. The right eye remained untreated and served as a control. The animals were checked daily for systemic symptoms and mortality. The ocular reactions were evaluated 1, 24, 48, and 72 hours after the instillation of the test substance. In order to determine the reversibility of the eye reactions additional evaluations of the ocular reactions were needed in this study. A slit-lamp was used to facilitate the evaluation.

- Other effects:
- - One animal vocalised upon instillation.
- At the end of the observation period (day 7) the conjunctiva of all animals was slightly stained by the test article. This slight staining of the conjunctiva was considered not to represent any risk of serious damage to the eyes because of its minimal intensity and the fact that no functional relevant parts of the eye were involved. In the course of the physiological regeneration of the conjunctiva such a slight staining will most probably disappear without permanent lesions. - Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the conditions of this experiment, the test substance was found to be not irritating or corrosive.
- Executive summary:
In a GLP compliant eye irritation study, performed according to OECD guideline 405, the test substance (32mg) was placed in the conjunctival sac of the left eye of three New Zealand White rabbits. The eyes were examined for 7 days. A mean cornea score of 1 and 0.66 was observed at 1 hour and 24 hours, respectively. Iris scores observed were 1 at 1 and 24 hours. Chemosis scores were 2, 1.33, and 1 at up to 24, 48 and 72 hours, respectively. Chemosis scores observed were 2, 1.67, and 1 at 1, 24, and up to 72 hours, respectively. The scores observed at the other time points were 0. Although irritation was observed in the eye, this was completely reversible within 7 days. Under the conditions of this experiment, the test substance was found to be not irritating or corrosive.
