Claims
- 1. An anticalculus oral composition which comprises an orally acceptable vehicle or base for such composition, an effective anticalculus proportion, about 0.01% to about 5% by weight of an orally acceptable azacycloalkane-2,2-diphosphonic compound (AAP) selected from the group consisting of compounds of the formula: ##STR8## wherein R is selected from the group consisting of hydrogen and alkyls of 1 to 3 carbon atoms and n is an integer from 3 to 5, and orally acceptable salts thereof and about 0.1% to about 5% by weight of a water soluble or water swellable synthetic anionic polymer (SAP) of a molecular weight in the range of about 1,000-2,000,000, which is effective to increase the anticalculus action of the APP in said composition.
- 2. An anticalculus oral composition according to claim 1 wherein the composition is a toothpaste, gel dentifrice, tooth powder, mouthrinse, mouthwash, tooth hardener, antiplaque composition, gum or lozenge, and the relative proportion of AAP to SAP is in the range of 1:50-50:1.
- 3. An anticalculus oral composition according to claim 2 wherein the AAP is azacycloheptane-2,2-diphosphonic acid or a water soluble salt thereof (AHP), the SAP is a polymeric sulfonate, phosphinate, phosphonate or siloxane.
- 4. An anticalculus oral composition according to claim 2 wherein the AAP is azacycloheptane-2,2-diphosphonic acid (AHP) and the SAP is a polyvinyl phosphonic acid or polyvinyl phosphonate, which is of a molecular weight in the range of about 1,000-1,000,000.
- 5. An anticalculus oral composition according to claim 4 which is a toothpaste, gel dentifrice or tooth powder which comprises about 0.2-2% of AHP and about 0.2-3% of SAP.
- 6. An anticalculus toothpaste or gel dentifrice according to claim 5 which comprises about 0.5-1.5% of AHP and about 0.3-1% of SAP.
- 7. An anticalculus toothpaste or gel dentifrice according to claim 6 which comprises about 0.5-1.5% of azacycloheptane-2,2-diphosphonic acid, about 0.3-1% of water soluble polyvinyl phosphonic acid or polyvinyl phosphonate, having recurring groups ##STR9## wherein M and M.sub.1 are hydrogen, alkali metal, or ammonium, and are the same or different, of a molecular weight in the range of about 6,000-100,000, about 0.02-1% of sodium fluoride, about 10-25% of finely divided silica dental polishing agent, about 20-35% of glycerol and/or sorbitol humectant(s), about 0.5-8% of gum and/or silica thickener(s), about 0.5-2% of a surfactant and about 35-55% of water.
- 8. An anticalculus toothpaste according to claim 7 which comprises about 0.1 to 0.6% of triclosan and is antiplaque.
- 9. An anticalculus oral composition according to claim 4 which is a mouthrinse or mouthwash which comprises about 0.1-2% of AHP and about 0.01-3% of SAP in an aqueous liquid medium.
- 10. An anticalculus mouthrinse or mouthwash according to claim 9 which comprises about 0.1-2% of azacylcoheptane-2,2-diphosphonic acid, about 0.1-3% of polyvinyl phosphonic acid or polyvinyl phosphonate, having recurring groups ##STR10## wherein M and M.sub.1 are hydrogen, alkali metal or ammonium and are the same or different, of a molecular weight in the range of about 6,000-100,000, about 5-20% of ethanol and about 75.0-94.8% of water.
- 11. A process for treating teeth to inhibit development of calculus thereon which comprises applying to the teeth a calculus inhibiting amount of a composition of claim 1.
- 12. A process according to claim 11 wherein the composition applied to the teeth is a toothpaste, gel dentifrice, tooth powder, mouthrinse, mouthwash, tooth hardener, antiplaque composition, gum or lozenge, the relative proportion of AAP to SAP is in the range of about 1:50-50:1, and the composition is applied to the teeth repeatedly.
