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.
