- RANGE FINDING TESTS:
-Selection of concentration for intradermal induction:
Intradermal injections (0.1 mL/injection site) were performed on the clipped shoulder of two guinea pigs, at concentrations of 1% and 5% v/v in arachis oil BP. The degree of erythema at the injection sites was assessed approximately 24, 48, 72 hours and 7 days after injection. Any proof of toxicity was recorded as well.
A concentration of 5% was selected as the highest concentration that caused mild to moderate skin irritation, and that was well tolerated systematically.
-Selection of concentration for topical induction:
The test material was applied on clipped flanks of two guinea pigs under occlusive dressing at the following concentrations: 100, 75, 50 and 25% v/v in arichis oil BP. The erythema and edema scores were determined approximately 1, 24, and 48 hours after dressing removal. 100% was selected for the topical induction of the main study as the highest concentration producing only mild to moderate dermal irritation.
-Selection of concentration for topical induction:
The test material was applied to the clipped flanks of two guinea pigs under occlusive dressings for an exposure period of 24 h at the following concentrations: 75%, 50% and 25% v/v in arachis oil BP) Erythema and edema scores were determined at approximately 1, 24, and 48 h after dressing removal.
The highest non-irritant concentration of the test material (100%) and one lower concentration were selected for the topical challenge stage of the main study.
