The present invention relates to a composition comprising an effective amount of a particulate zinc material, an effective amount of a detersive surfactant including a surfactant with an anionic functional group, an effective amount of a pyrithione or a polyvalent metal salt of a pyrithione, a dispersed gel network phase comprising: i) at least about 0.05% of one or more fatty amphiphiles, by weight of said shampoo composition; ii) at least about 0.01% of one or more secondary surfactants, by weight of said shampoo composition; and iii) water; and at least about 20% of an aqueous carrier, by weight of said shampoo composition.

Composition comprising a particulate zinc material, a pyrithione or a polyvalent metal salt of a pyrithione and a gel network

The present invention relates to a composition comprising an effective amount of a particulate zinc material, an effective amount of a surfactant including a surfactant with an anionic functional group wherein the particulate zinc material has a relative zinc lability of greater than about 15 % and wherein the composition comprises less than 5.5 micromoles of a zinc binding material per gram of the particulate zinc material/per m/gram surface area of the particulate zinc material.

Composition comprising particulate zinc material with a high relative zinc lability

In one embodiment, a method of modeling interactions with keratinous tissue may comprise the steps of providing a nonwoven mimic and performing an act on the mimic as may be performed on keratinous tissue. The nonwoven mimic has a surface energy representative of keratinous tissue. In another embodiment, a method of modeling interactions with keratinous tissue may comprise the steps of: providing a mimic comprising from about 60% or greater rayon, from about 40% or less polyester, and a surface energy representative of keratinous tissue; and performing an act on the mimic as may be performed on keratinous tissue. The mimic is preferably a nonwoven mimic.

Methods of use of a nonwoven keratinous tissue mimic

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.
