Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the evaluated conditions, the test substance shows no skin irritating potential.
- Executive summary:
0.5 mL of the test item was tested for primary dermal irritation in 3 female New Zealand White rabbits. The exposure period was 4 hours. After the exposure period, the remaining test substance was removed carefully with warm tap water.
Examinations of the skin took place after 30-60 minutes as well as 24, 48 and 72 hours after removal of the patches. Additionally the animals were observed for any clinical signs of systemic toxicity.
The test substance caused minor dermal reactions in form of very slight erythema in two animals 30-60 minutes after removal of the plaster.
Overall, mean scores for dermal irritation after 24, 48 and 72 hours were 0.0 for erythema and eschar formation and 0.0 for oedema formation. No clinical signs of systemic toxicty were observed.
Based on the results obtained, the test item does not show skin irritant potential.
