TEST SITE
Approximately 24 hours before treatment, the dorsal fur was shaved with electric clippers, exposing an area of approximately 150 square centimeters (10x15 cm). Whenever considered necessary the skin areas concerned were re-clipped at least 3 hours before the observations, to facilitate scoring
The test substance was applied to the skin of one flank, using a patch of 2x3 cm. A similar patch (but without test substance and water) was applied to the contralateral flank, to act as a procedural control. Both patches were mounted on Micropore tape, which was wrapped around the abdomen and secured with Coban elastic bandage.
REMOVAL OF TEST SUBSTANCE
Four hours after the application, the dressing was removed and the remaining test substance removed using a tissue moistened with tap-water and subsequently a dry tissue.
