Abstract
Disclosed are oral compositions comprising one or more linear polyphosphates having an average chain length of about 4 or more, sodium monofluorophosphate, a buffering agent, an abrasive polishing material containing less than 23% calcium, and one or more aqueous carriers, wherein the oral composition has a total water content of from about 5% to about 20%.
Claims14
An oral composition consisting essentially of:
- a. an effective amount of one or more linear polyphosphates having an average chain length of greater than about 6, wherein the linear polyphosphate is the effective anticalculus agent;
- b. from about 0.15% to about 2.28% of sodium monofluorophosphate;
- c. an effective amount of a buffering agent;
- d. from about 6% to about 70% of an abrasive polishing material containing less than 23% calcium;
- and
- e. from about 50% to about 99% of one or more aqueous carriers;
- wherein said oral composition has a total water content of from about 5% to about 20%, has a pH of from about 6.5 to about 10, and is free of ionic fluoride to avoid a reaction between said ionic fluoride and said linear polyphosphate which compromises the ability of said oral composition to provide polyphosphate to the oral surfaces.

A method of improving delivery of linear polyphosphate to oral cavity surfaces by administering an oral composition consisting essentially of:
- a. an effective amount of one or more linear polyphosphates having an average chain length of greater than about 6, wherein the linear polyphosphate is the effective anticalculus agent;
- b. from about 0.15% to about 2.28% of sodium monofluorophosphate;
- c. an effective amount of a buffering agent;
- d. from about 6% to about 70% of an abrasive polishing material containing less than 23% calcium;
- and
- e. from about 50% to about 99% of one or more aqueous carriers;
- wherein said oral composition has a total water content of from about 5% to about 20%, has a pH of from about 6.5 to about 10 and is free of ionic fluoride to avoid a reaction between said ionic fluoride and said linear polyphosphate which compromises the ability of said composition to provide polyphosphate to the oral surfaces.
