Skin sensitisation
Administrative data
- Endpoint:
- skin sensitisation: in vivo (non-LLNA)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
Data source
Reference
- Reference Type:
- study report
- Title:
- Unnamed

Materials and methods
Test guideline
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 406 (Skin Sensitisation)
- Deviations:
- yes
- Remarks:
- no information on purity of the test material; both flanks were exposed during challenge, no reliability check done, no positive control used. Method given in very summarized form.
- GLP compliance:
- not specified
- Type of study:
- Buehler test
- Justification for non-LLNA method:
- A valid Buehler study report was available before REACh came into force. In combination with other LLNA tests the Buehler test is used in a weight of evidence approach.
