Methods of use of substrate having properties of keratinous tissue

摘要

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/m² to about 50 mJ/m², a polar component of the total surface energy of from about 0 mJ/m² to about 15 mJ/m², a zeta-potential at a pH of about 5.0 of from about -30 mV to about 30 mV, and combinations thereof, and performing at least one analysis of the substance-coated surface.
