The present invention a) i. 0.1% to 1.5% zinc ions, and ii. 0.2% to 3% divalent metal ions containing 0.1% to 2% tin (II) ions; b) a fluoride ion source; c) a silica dental abrasive; d) having a molecular weight of less than 1000 and capable of forming a water-soluble complex with zinc ions, the amount of linear polyphosphate having a chain length of 4 or more being less than 0.2%; Two or more chelating agents, e) an oral acceptable carrier comprising at least a total of 20% water; The composition has a pH of 5 to 6.5, the molar ratio of chelator to divalent metal ions is at least 0.70: 1, and at least 80% by weight of the total zinc ions are present in the composition. The present invention relates to a solubilized aqueous oral composition. The composition of the present invention provides improved antibacterial activity with the zinc / stannous combination without significant taste, coloration or stability problems compared to compositions having low concentrations of chelating agents. Has been found. |
