Skin sensitisation
Administrative data
- Endpoint:
- skin sensitisation: in vivo (non-LLNA)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 01 Feb - 22 Apr 1994
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: GLP-Guideline study with acceptable restrictions (no analysis of the test substance, no data on positive controls, challenge on both flanks)

Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 406 (Skin Sensitisation)
- Version / remarks:
- Buehler Test
- Deviations:
- yes
- Remarks:
- no analysis of the test substance, no data on positive controls, challenge on both flanks
- GLP compliance:
- yes
- Type of study:
- Buehler test
- Justification for non-LLNA method:
- A valida Buehler study was available before REACh came into force, therefore no additional LLNA test was conducted.
