ABSTRACT:
A test method is described for comparing the relative affinity of products for a target substance using a substrate ordinarily and visibly sensitive to the products. The test method is useful in one embodiment for comparing the ability of harsh cleansers to remove fatty acids from the skin with mild cleansers that do not remove fatty acids to the same extent using a visually compelling substrate, such as a fresh cut flower.
