Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Conclusions:
- Classification: not irritating
- Executive summary:
Skin irritation was tested in a guideline study according to OECD guideline 404 in rabbits. 24 hours up to three days after treatment, the skin did not show any sign of erythema or edema. Mean scores on all observation time points after application were 0 for the three animals.
The test substance was classified as not irritating.
