- RANGE FINDING TESTS:
Selection of Concentration for Topical Induction:
Two previously untreated guinea pigs were treated with undiluted test material and three concentrations of the test material in distilled water (75%, 50%, and 25% v/v). Applications were made to the clipped flanks under occlusive dressings for an exposure period of 6 hours. The degree of erythema and oedema was evaluated 24 and 48 hours after dressing removal. The highest concentration of the test material producing only mild dermal irritation was selected for the topical induction stage of the main study.
Selection of Concentration for Topical Challenge
Two guinea pigs were treated with undiluted test material and one concentration of the test material in distilled water (75% v/v). These animals had been treated identically to the control animals of the main study on Days 0, 7 and 14. Applications were made to the clipped flanks under occlusive dressings for an exposure period of six hours. The degree of erythema and oedema was evaluated 24 and 48 hours after dressing removal. The highest concentration of the test material which produced no evidence of dermal irritation, and one lower concentration were selected for the topical challenge stage of the main study.
MAIN STUDY
A. INDUCTION EXPOSURE
- No. of exposures: 3

- Control group: 10 animals
- Site: left flank, 20mm x 20 mm patch
- Frequency of applications: day 0, 7 and 14.
- Concentrations: undiluted
Approximately 24 hours after each induction application (Days 1, 8 and 15) the degree of erythema and oedema was quantified.
B. CHALLENGE EXPOSURE
- No. of exposures: 1
- Day(s) of challenge: day 28
- Exposure period: 6 hours
- Test groups: 20 animals
- Control group: 10 animals
- Site: right flank, 20 mm x 20 mm
- Concentrations: undiluted, 75% v/v
- Evaluation (hr after challenge): Approximately 24 and 48 hours after dressing removal, the degree of erythema and oedema was quantified - Challenge controls:
- similar as the test group
- Positive control substance(s):
- not required
