- RANGE FINDING TESTS: Intradermal Pre-test: 6 intradermal injections in groups of two per animal were applied to each animal .A) front row: 2 injections each of 0.1 mL Freund's adjuvant without test substance emulsified with 0.9% aqueous NaCI-solution in a ratio of 1:1B) middle row: 2 injections each of 0.1 mL of a test substance formulation in an appropriate vehicle at the selected concentrationC) back row: 2 injections each of 0.1 mL Freund's adjuvant / 0.9% aqueous NaCI-solution (1:1) with test substance at the selected concentration.- Site of application: neck region- No . of animals: 2 per test substance concentration- Reading: 24 h after the beginning of applicationEpicutaneous Pre-test: For detecting a possible influence on irritating effects of previous intradermal treatment with Freund's adjuvant, animals pre-treated with Freund's adjuvant / 0 .9% aqueous NaCI-solution (1:1) each, in the same manner as intradermal pre-test referring front row (A) and back row (C) without test substance about 2 weeks prior to the application of the test substance were used .- Amount applied: 2 x 2 cm gauze patches (6 layers surgical gauze) containing 0.5 mL of the test substance formulation were applied to the skin of the flanks under an occlusive dressing. The dressing consisted of rubberized linen patches (4 x 4 cm), patches of Idealbinde (5 x 5 cm) and Fixomull® Stretch (adhesive fleece).- Duration of exposure: 24 hours- Site of application: flank- Number of test animals: 3 per test substance concentration- Readings: 1 h, 24 h and 48 h after removal of the patchesMAIN STUDYINDUCTION EXPOSURE - IntradermalIntradermal injections in groups of two per animal were given.A) front row: 2 injections each of 0.1 mL Freund's adjuvant without test substance emulsified with 0.9% aqueous NaCI-solution in a ratio of 1:1B) middle row: 2 injections each of 0.1 mL of the undiluted vehicle or 0.1 mL of a test substance formulation in an appropriate vehicle at the selected concentrationC) back row: 2 injections each of 0.1 mL of a 50% formulation of the vehicle without test substance emulsified with Freund's adjuvant/ 0.9% aqueous NaCI-solution (1:1) or 0.1 mL Freund's adjuvant / 0.9% aqueous NaCI-solution (1:1) with test substance at the selected concentration.- Site of application: neck region- Reading: 24 h after the beginning of applicationINDUCTION EXPOSURE - EpicutaneousEpicutaneous induction was carried out one week after intradermal induction.- Amount applied: 2 x 4 cm gauze patches (6 layers surgical gauze) containing the test substance formulation were applied to the skin of the neck region under an occlusive dressing. The dressing consisted of rubberized linen patches (4 x 6 cm) and Fixomull® Stretch (adhesive fleece). 1 mL of the test substance formulation was applied to each animal. The control animals were not treated since the distilled water used as formulating agent was not expected to influence the result of the study. - Duration of exposure: 48 hours- Site of application: neck region, same area as in the case of the previous intradermal application- Readings: directly after removal of the patchCHALLENGE EXPOSUREThe challenge was performed 14 days after the epicutaneous induction.- Amount applied: 2 x 2 cm gauze patches (6 layers surgical gauze Ph . Eur. from Lohmann GmbH & Co . KG) containing the test substance formulation were applied to the skin of the flank under an occlusive dressing. The dressing consisted of rubberized linen patches (4 x 4 cm from Russka), patches of Idealbinde (5 x 5 cm from Pfälzische Verbandstoff-Fabrik) and Fixomull® Stretch (adhesive fleece) from Beiersdorf AG. 0.5 mL of the test substance formulation was applied to each animal.- Duration of exposure: 24 hours- Site of application: intact flank- Readings: 24 and 48 h after the removal of the patch
- Challenge controls:
- A positive control (reliability check) with a known sensitizer is not included in this study. However, a separate study is performed twice a year in the laboratory. The positive controls with Alpha-Hexylcinnamaldehyde showed that the test system was able to detect sensitizing compounds under the laboratory conditions chosen.
- Positive control substance(s):
- yes
