Skin irritation / corrosion
Administrative data
- Endpoint:
- skin irritation: in vivo
- Type of information:
- experimental study
- Adequacy of study:
- other information
- Study period:
- From July to August
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Comparable to guideline study with acceptable restrictions: A combined study on acute dermal toxicity and on local tolerance was used to assess skin irritation/corrosion. The study design and reporting deviates from the current OECD TG 404, however, the study is considered sufficient for assessment of this endpoint.
Cross-reference
- Reason / purpose for cross-reference:
- reference to same study

Results and discussion
Any other information on results incl. tables
The mean values of findings relevant for classification (reddening, scab formation and swelling of the skin) at the time-points 24, 48 and 72 hours after the end of administration were 0.
Applicant's summary and conclusion
- Executive summary:
A single dermal administration of the test substance for 24 hours to male and female rats at a dose of 2000 mg/kg was tolerated without any local irritations. The mean values of findings relevant for classification (reddening, scab formation and swelling of the skin) at the time-points 24, 48 and 72 hours after the end of administration were 0.
