Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Application of the test substance onto skin did not provoke any skin reaction. The substance is therefore not considered to be irritating to skin.
- Executive summary:
A GLP-compliant Acute dermal irritation/corrosion study according to OECD TG 404 was performed to assess the skin irritation potential of the test substance to the rabbit. Three rabbits received a single four hour, semi-occlusive, dermal administiation of approximately 0.5g of the test substance (moistened with water) and were observed for four days. No dermal reaction was observed in any animal throughout the duration of the study. The means of scores for oedema and erythema at approximately 24, 48 and 72 hours after administration, were 0 for each animal. As a result, the substance is not considered to be irritating to skin.
