- No symptoms of systemic toxicity were observed in the animals during the test period and no mortality occurred.
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- All areas to be treated with the test substance and all control areas were normal before the application and at each observation time. Based on the results, the test substance is not a skin irritant.
- Executive summary:
Assessment of the possible irritation/corrosion by the test substance following a single application to the intact skin of rabbits was determined according to the OECD Guideline 404 and B.4 EU Method, with GLP. 0.5 g of the test substance moistened with deionised water, was applied via a patch to a site of 2.5 cm x 2.5 cm of the intact skin of each of 3 New Zealand White rabbits and covered by a semi-occlusive dressing. The duration of exposure was 4 hours. No symptoms of systemic toxicity were observed in the animals during the test period and no mortality occurred. All areas to be treated with the test substance and all control areas were normal before the application and at each observation time. Based on the results, the test substance is not a skin irritant.
