- Executive summary:
The dermal sensitization potential of the test article (liquid, purity >98%, batch no. AH2/170) was evaluated in the Maximization Test using male Himalayan spotted guinea pigs. This study was performed in accordance with Swiss GLP (2000) and OECD GLP (1997). The study design was based on OECD 406 (1993) and Directive 96/54/EEC, B.6 (1996). The test article was prepared in PEG 300 (vehicle) just prior to each dosing procedure. A pre-test rangefinder determined the appropriate doses for the intradermal and epidermal inductions and challenge phase. The test group (10 animals) received intradermal induction injections of 0.1 ml/site of a 1:1 mixture of Freund’s Complete Adjuvant (FCA):saline, 50% test article in vehicle, and 50% test article in 1:1 FCA/saline. A control group (5 animals) received the same induction treatment with the exclusion of test article. Pre-test results: The epidermal induction of sensitization was conducted under occlusion with 75% MTDID 16591 in vehicle (test group) or vehicle only (control group) one week after the intradermal induction. Two weeks after epidermal induction the control and test animals were challenged by epidermal application of 25% of the test article and vehicle only under occlusive dressing. Skin reactions were evaluated at 24 and 48 hours after removal of the dressing. A positive control (2-mercaptobenzothiazole) is tested by this contract lab approximately every 6 months and the most recent test confirmed the validity of the experimental technique. There was no evidence of skin sensitization following treatment with the test article. No erythema or edema was observed at any site in either the control or test article group (0/10). A loss of body weight (7.4%) was observed in 1 test group animal during the acclimatization period; the animal recovered between the treatment start and the end of the study. Based on the results this study, there was no evidence of skin sensitization following treatment with the test article.
