Patent ID: 8119168

Claim:
A composition comprising: a. an effective amount of a zinc containing material having an aqueous solubility within the composition of less than 25% by weight at 25° C. wherein the zinc containing material is selected from the group consisting of zinc aluminate, zinc oxide, calamine, zinc phosphate, zinc selenide, zinc sulfide, zinc silicates, zinc silicofluoride, zinc borate, or zinc hydroxide and zinc hydroxy sulfate, and mixtures thereof; b. from about 5% to about 50% by weight of a detersive surfactant wherein the detersive surfactant is selected from the group consisting of anionic, cationic, amphoteric or zwitterionic surfactants and mixtures thereof; c. a component selected from the group consisting of sodium bicarbonate, sources of carbonate anions and mixtures thereof; and d. from about 40% to about 95% by weight water; wherein the pH of the composition is greater than 7 and further wherein the zinc containing material has a relative zinc lability of greater than 15% and wherein the composition does not contain basic zinc carbonate.
