Test system
- Type of coverage:
- semiocclusive
- Preparation of test site:
- shaved
- Vehicle:
- water
- Remarks:
- moistened
- Controls:
- no
- Amount / concentration applied:
- 0.5g
- Duration of treatment / exposure:
- 4 hours
- Observation period:
- 7 days
- Number of animals:
- 3 male rabbits
- Details on study design:
- 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.
Applicant's summary and conclusion
- 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.
