  • Patent number: 9381148
    Abstract: 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 m2/gram surface area of the particulate zinc material.

  • Publication number: 20090291057
    Abstract: Methods of cleansing, conditioning and optionally therapeutically treating skin, hair, and/or other keratinous surfaces of a companion animal are provided. The method includes: contacting the skin, hair, and/or other keratinous surfaces of a companion animal with a companion animal care composition, the composition having a cleansing component, and a conditioning component; and optionally rinsing the skin, hair, and/or other keratinous surfaces of the companion animal with water; wherein after use of the composition, the composition provides a friction coefficient of from about 0.65 to about 0.8. Also included are articles of commerce having a container containing a companion animal care composition, which composition provides cleansing, conditioning, and optional treatment benefits to a companion animal. The container has instructions for cleansing, conditioning, and optionally treating the companion animal.
