Administrative data
- Endpoint:
- skin irritation: in vivo
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: The study is reliable with restrictions due to limited reporting (non-GLP study). Basic data are given and study is sufficient for endpoint evaluation.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test substance did not cause skin irritation but irritation of mucous membrane.
The test substance is not irritating to the skin. - Executive summary:
The study was conducted according to the method described by Draize et al. (1944) and is reliable with acceptable restrictions. Restrictions are due to limited reporting in times befor GLP. Skin irritation was tested in albino rabbits in vivo. Neat test substance (0.5ml unchanged, no vehicle) was applied on abraded and intact skin (occlusive) for 24h (reading 24 -72h).
The test substance is not irritating to the skin.
