Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Not irritant to the rabbit skin.
- Executive summary:
Method:
Skin irritation potential of the substance was assessed according to OECD guideline 404. Test substance was applied to the skin of 3 rabbits, under semiocclusive coverage for 4 h. Signs of irritation in terms of erythema and oedema were recorded.
Results:
No signs of oedema were noted; slight signs of erythema were seen in 1/3 rabbits, which were reversible within 48 hours.
