Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- No classification is assigned for the registration substance with respect to the endpoint skin irritation.
- Executive summary:
The skin irritation property of the registration substance was investigated according to the OECD Guideline 404. Three rabbits were treated topically with 0.5 ml triethylenglycoldibutylether (representative material for the registration substance). The animals exhibited transient erythema and edema that were fully reversible within 14 days of observation period. The obtained mean scores for erythema and edema were 1.3 and 0.2 respectively. Based on the obtained result the registration substance was found to be not irritating according to the EU criteria.
