Method of product evaluation comprising the steps of applying at least one substance to a surface of an artificial substrate to form a substance-coated surface, wherein the substrate surface demonstrates at least one physical property selected from the group consisting of a total surface energy of from about 15 mJ/mto about 50 mJ/m, a polar component of the total surface energy of from about 0 mJ/mto about 15 mJ/m, a zeta-potential at a pH of about 5.0 of from about &#x2212;30 mV to about 30 mV, and combinations thereof, and performing at least one analysis of the substance-coated surface.

Methods of use of substrate having properties of keratinous tissue

Article of manufacture comprising a substrate and a coating layer. The coating layer comprises at least one coating material, and is stably affixed to the substrate to form a stable, coated surface. The coated surface has a texture that mimics the topography of mammalian keratinous tissue and demonstrates at least one physical property representative of mammalian keratinous tissue, selected from the group consisting of a total surface energy of from about 15 mJ/mto about 50 mJ/m, a dispersive component of the surface energy of from about 15 mJ/mto about 50 mJ/m, a polar component of the total surface energy of from about 1 mJ/mto about 14 mJ/m, a zeta-potential at a pH of about 5.0 of from about &#x2212;40 mV to about 30 mV, and combinations thereof.
