- Methodology:
The upper back between the scapulae served as the treatment area. Approximately 2 ml of the test material, or an amount sufficient to cover the contact surface, was applied to the 1x1 absorbent pad portion of a clear adhesive dressing. This was then applied to the appropriate treatment site to form a semi-occlusive patch.
Induction Phase:
Patches were applied three (3) times per week (e.g., Monday, Wednesday, and Friday) for a total of nine (9) applications. The site was marked to ensure the continuity of patch application. Following supervised removal and scoring of the first Induction patch, participants were instructed to remove all subsequent Induction patches at home, twenty-four hours after application. The evaluation of this site was made again just prior to reapplication. If a participant was unable to report for an assigned test day, one (1) makeup day was permitted. This day was added to the induction period.
With the exception of the first supervised induction Patch reading, if any test site exhibited a moderate (2-level) reaction during the Induction Phase, application was moved to an adjacent area. Applications were discontinued for the remainder of this test phase, if a moderate (2-level) reaction was observed on this new test site. Applications would also be discontinued if marked (3-level) or severe (4-level) reactivity was noted.
Rest periods consisted of twenty-four hours following each Tuesday and Thursday removal, and forty-eight hours following each Saturday removal.
Challenge Phase:
Approximately two (2) weeks after the final Induction patch application, a Challenge patch was applied to a virgin test site adjacent to the original Induction patch site, following the same procedure described for Induction, The patch was removed and the site scored at the clinic twenty-four and seventy two hours post-application.
Evaluation Criteria (Erythema and additional Dermal Sequelae):
0 = No visible skin reaction
0.5 = Barely perceptible
1 = Mild
2 = Moderate
3 = Marked
4 = Severe
E = Edema
D = Dryness
S Staining
P = Papules
V Vesicles
B = Bullae
U = Ulceration
Sp = Spreading
Erythema was scored numerically according to this key. If present, additional Dermal Sequelae were indicated by the appropriate letter code and a numerical value for severity. - Positive control substance(s):
