Patent ID: 7063833

Claim:
A single phase dentifrice composition comprising: a. an effective amount of one or more linear polyphosphates having an average chain length of about 4 or more as the sole anti-calculus agent(s), wherein said polyphosphate(s) is water soluble and susceptible to hydrolysis; b. an effective amount of a stannous ion source; and c. a total water content of up to about 20% by weight of the composition, wherein the single phase dentifrice composition has a molar ratio of polyphosphate anion to stannous ion of from about 0.2:1 to about 5:1, wherein the stannous ion source comprises a stannous salt other than stannous fluoride or stannous monofluorophosphate, and the efficacy of the stannous ion in the dentifrice is not reduced by the polyphosphate.
