- Details on study design:
- RANGE FINDING TESTS:
- Amount applied:
2 x 2 cm filter paper strips were applied to the skin of the flanks under an occlusive dressing (the bandage consists of rubberized linenpatches 4 x 4 cm from Russka and Fixomull Stretch (adhesive fleece) from Beiersdorf AG). In the case of liquids the test filter paper strip was
soaked in the test substance formulation; thus the animals were exposed to about 0,15 g of the test substance formulation.
- Exposure period :
The test substance was applied 2 times for 24 hours within a period of 96 hours in order to detect non-specific phenomena that are not caused by a sensitization reaction but could possibly be attributed to a shift in the irritation threshold .
- Site of application: flank, respective on the same area
- Number of test animals 4 per test concentration
- Readings: about 24 and 48 h after the beginning of application
- Assessment of skin findings: according to Draize JH (1959)
MAIN STUDY
A. INDUCTION EXPOSURE
- No. of exposures: 6 intradermal injections in groups of tw o per animal (2 injections each of 0.1 ml Freund's adjuvant without test substance emulsified with 0.9 % aqueous NaCl-solution in a ratio of 1:1; 2 injections each of 0.1 ml of the test substance formulation; 2 injections each of 0.1 ml Freund's adjuvant/0.9% aqueous NaCl-solution (1:1) with test substance);
- Exposure period:
- Test groups: 10 animals
- Control group: 5 animals
- Site: shoulder
- Frequency of applications: Percutaneous induction was carried out one week after intradermal induction
- Duration: 48 h
- Concentrations: 2 x 4 cm filter paper strips were applied to the skin of the shoulder under an occlusive dressing (the bandage consists of gubberized linenpatches 4 x 4 cm from Russka and Fixomull Stretch (adhesive fleece) from Beiersdorf AG) . The filter paper strip was soaked in the test substance formulation; thus the animals were exposed to about 0.3 g of the test substance formulation. The control animals were not treated since the distilled water used as formulating agent was not expected to influence the result of the study.
B. CHALLENGE EXPOSURE
- No. of exposures: 1
- Day(s) of challenge: 21 days after induction
- Exposure period: 24 h
- Test groups: 10 animals
- Control group: 5 animals
- Site: in t act clipped flank
- Concentrations: 2 x 2 cm filter paper strips were applied to the skin of the flank under an occlusive dressing (the bandage consists oferubberized linenpatches 4 x 4 cm from Russka and Fixomull Stretch (adhesive fleece) from Beiersdorf AG). The test filter paper strip was soaked in the test substance formulation; thus the animals were exposed to about 0.15 g of the test substance formulation.
- Evaluation (hr after challenge): 24 h and 48 h after the removal of the patch; according to Draize JH (1959) - Challenge controls:
- A positive control (reliability check) with a known sensitizer is not included in this study however a separate study was performed twice a year in the laboratory (Study No. 0H0038/912125, BASF AG)
- Positive control substance(s):
- yes
- Remarks:
- 1-chlor-2,4-dinitro-benzol; BASF AG, 0H0038/912125
Results and discussion
- Positive control results:
- After the challenge (24 hours after the removal of the test patch) with the 1% 1-chlor-2,4-dinitro-benzol preparation in ethanol well-defined erythema and slight edema could be observed in 6 out of 8 test group animals. Two animals showed very slight erythema, one of them additionally had very slight edema .
