Abstract:
1. An oral care composition, comprising: (a) a first phase comprising a safe and effective amount of a halogenated diphenyl ether anti-microbial and a first orally acceptable aqueous vehicle; and (b) a second phase comprising a stannous salt, a polycarboxylic acid, and a second orally acceptable aqueous vehicle; wherein said second phase comprises no less than 10 molar percent of soluble stannous ion respective to a mathematical of moles of said soluble stannous ion and moles of said stannous salt in said second phase; wherein said polycarboxylic acid is selected from the group consisting of citric acid, lactic acid, tartaric acid, succinic acid, malic acid, fumaric acid and combinations thereof; wherein said second phase further comprise a silica abrasive and does not contain a peroxide whitening agent; wherein said composition further comprises sodium lauryl sulfate; where said sodium lauryl sulfate is substantially contained in said first phase thereby increasing uptake of said halogenated diphenyl ether anti-microbial, and wherein the polycarboxylic acid is present in an amount sufficient to effectively stabilize soluble stannous ion concentration in said second phase.
