Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 406 (Skin Sensitisation)
- Deviations:
- yes
- Remarks:
- a temperature of 18°C was registered during this study instead of 19°C (minimal limit) as planned in the experimental protocol. This deviation did not, in any cas, influe,ce the development and the result of the study

- yes
- Type of study:
- guinea pig maximisation test
- Justification for non-LLNA method:
- This Guinea pig maximisation test realised in 2002 before the publication of the Murine Local Lymph Node Assay (LLNA) Performance standards by ECVAM in 2008.

- Preliminary study:
- Determination of the Maximum Non Necrotizing concentration: MNNC
The test product was injected by intradermal route at the following concentrations: 100%, 50%, 25%, 12.5%, 6.25%, 3.125% diluted in a physiological saline solution
- Determination of the pre- Maximum Non Irritant concentration: pre-MNIC
The test product was applied under an occlusive dressing during 24 hours at the following concentrations: 100%, 50%, 25%, 12.5% diluted in a physiological saline solution
- Determination of the Maximum non-irritant concentration:
After induction by intradermal injection with physiological saline solution and by topical application with distilled water and a 17-days rest phase, the challenge phase under occlusive dressing for 24 hours consists in a single topical application of the test product at the following concentration 100%, 50%, 25%, 12.5% diluted in a physiological saline solution - Challenge controls:
- Group 1 (negative control): 5 females
- Positive control substance(s):
- no
