Applicant's summary and conclusion
- Interpretation of results:
- other: Not Irritant
- Conclusions:
- Not irritating.
- Executive summary:
Dorsal skin and ears of rabbits were exposure to the substance at different time of exposures. At the highest tested exposure time (i.e. 20 hours application), after 24 hours observation, erythema score could not be assessed, due to remainders of yellow color of the substance. After 8 days, no sign of irritation was observed.
At the lower tested exposure time, no signs of irritation were observed.
Conclusion
The substance is not a skin irritant.
