Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test material was not irritating to the skin in this in vivo test in rabbits according to OECD TG 404
- Executive summary:
Purpose
The purpose of this assay was to identify the skin irritation/corrosion potential of the test item when applied to the intact skin of previously shaven rabbits for a 4 hours period under semiocclusive conditions. This study should provide a rational basis for risk assessment to the irritating potential of the test item in man.
Study Design
To test for primary skin irritation, 0.5 mL of the test material was spread onto 6 cm2 patches and applied to the intact skin of previously shaven rabbits for a 4 hours period under semiocclusive conditions. The first examination of the treated skin sites followed 1 hour after removal of the patches. Thereafter, examinations were performed after 24, 48, and 72 hours.
Results
Under the conditions of the present study no signs of irritation were seen.The evaluation of the mean scores yields zero at all time points investigated.
Conclusion
No skin irritating potential could be detected, thus the test item should not be classified as a skin irritant according to EU Directive 67/548/EC amended and repealed by EU Regulation No. 1272/2008 and CLP.
