Patent ID: 8906347

Claim:
An aqueous oral composition comprising: a single phase comprising: a) from about 0.2% to about 3% divalent metal ions comprising: (i) from about 0.1% to about 1.5% of zinc ions; (ii) from about 0.1% to about 2% of tin (II) ions; and b) a source of fluoride ions; c) a silica dental abrasive; d) one or more chelants having a MW of less than about 1000, wherein the chelants comprise less than about 0.2% linear polyphosphates having a chain length of four or more; e) an orally acceptable carrier comprising at least about 20% total water; wherein the pH of the composition is from about 5 to about 6.5, the molar ratio of the chelants to the divalent metal ions is at least about 0.70:1 and at least about 80% by weight of the total zinc ions are solubilised within the composition and wherein, if orthophosphate ions are present, the molar ration of orthophosphate ions to zinc ions is less than about 0.2:1.
