Skin irritation / corrosion
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:
- comparable to guideline study with acceptable restrictions
- Remarks:
- Study conducted prior to GLP, no guideline followed as none was available in 1982 (OECD 401: 1987). However, the available information is documented sufficiently and allows the conclusion that the study was properly conducted with a scientifically acceptable method.

Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (corrosive) based on GHS criteria
- Conclusions:
- The study was conducted according to Code of Federal Regulations, Title 16, Section 1500.41 on the registered substance itself. The method is to be considered scientifically reasonable. Hence, the results can be considered as reliable to assess the skin irritating properties of the test substance in rabbits. The primary irritation index was calculated from the individual results, this resulted in mean value of 4 for edema in all tested animals, grey-white (24h), later (72h) red-brown, dry leather-like eschar has been observed, coming off after 8 days (starting scarred recovery) and hence, the substance has to be classified as corrosive to the skin.
- Executive summary:
In a skin irritation study ( Code of Federal Regulations, Title 16, Section 1500.41), male rabbits (six animals, New Zealand White) were dermally exposed to 500 µL of test substance for 24 hours. Animals then were observed for 8 days; the primary irritation index was calculated from the results.
This resulted in a primary irritation index of 4 for edema in all tested animals; further, grey-white (24h), later (72h) red-brown, dry leather-like eschar has been observed, coming off after 8 days (starting scarred recovery) and hence, the substance has to be classified as corrosive to the skin.
