Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test item was determined to be not irritating to the skin.
- Executive summary:
An in-vivo skin irritation/corrosion test was performed according to the OECD Guideline 404 (GLP study). Three male and three female New Zealand White rabbits were treated topically on each of two test sites which were previously clipped free of hair. 0.5 g of test item was place in contact with eact test site. The test sites were covered with gauze patches and the trunk of each animal was wrapped with a sheet of cheesecloth. The test material was in contact with the skin for 4 hours, after which the animals were unwrapped and the test item removed. The test sites were scored for irritating using the method of Draize at 30 minutes after unwrapping, at 24, 48 and 72 hours. No irritation was notes on any of the test sites during any of the scoring intervals (erythema and edema scores of 0). All the animals remained healthy throughout the study. Based on these results, the test item was determined to be not irritating to the skin.
