Skin sensitisation
Administrative data
- Endpoint:
- skin sensitisation: in vivo (non-LLNA)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:

Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 406 (Skin Sensitisation)
- GLP compliance:
- yes
- Type of study:
- guinea pig maximisation test
- Justification for non-LLNA method:
- Study was conducted in 1996, GPMT was method of choice at the time. No new LLNA test is required since GPMT available is of good quality and allows hazard assessment for skin sensitization.

Any other information on results incl. tables
No clinical signs and no deaths were noted during the study. No cutaneous reactions were observed after the challenge application. The guinea-pigs which were used in a recent study, showed a satisfactory sensitization response in 100% animals using a positive sensitizer.
Under the experimental conditions and according to the maximization method of Magnusson and Kligman, no cutaneous reactions attributable to the sensitization potential of the test substance at a concentration of 20% were observed in guinea-pigs.
