Abstract
Official abstract text for this publication.
Disclosed are oral care compositions of phosphonate and sulfonate group containing polymer compositions that have targeted uses with divalent cations and surfaces having divalent cations. These compounds can be used to deliver anionic character to surfaces such as calcium hydroxyapatite.
First claim
Opening claim text (preview).
What is claimed is: 1. An oral care composition comprising: (a) from about 5% to about 70%, by weight of the composition, of water, and (b) a polymer made from vinyl sulfonate monomer and vinyl phosphonate monomer, wherein the polymer has a percent ratio of vinyl sulfonate monomer to vinyl phosphonate monomer of from 70:30 to 30:70. 2. The oral care composition of claim 1 , wherein the oral care composition comprises from about 0.1% to about 11%, by weight of the oral care composition, of metal ion source. 3. The oral care composition of claim 2 , wherein the metal ion source comprises stannous ion source, zinc ion source, copper ion source, or combinations thereof. 4. The oral care composition of claim 3 , wherein the stannous ion source comprises stannous fluoride, stannous chloride, stannous pyrophosphate, or combinations thereof. 5. The oral care composition of claim 3 , wherein the zinc ion source comprises zinc fluoride, zinc chloride, zinc gluconate, zinc citrate, zinc phosphate, or combinations thereof. 6. The oral care composition of claim 1 , wherein the oral care composition comprises fluoride source. 7. The oral care composition of claim 6 , wherein the fluoride source comprises sodium fluoride, stannous fluoride, indium fluoride, amine fluoride, sodium monofluorophosphate, or combinations thereof. 8. The oral care composition of claim 1 , wherein the oral care composition comprises abrasive. 9. The oral care composition of claim 8 , wherein the abrasive comprises silica, alumina, calcium pyrophosphate, calcium carbonate, or combinations thereof. 10. The oral care composition of claim 1 , wherein the oral care composition comprises surfactant. 11. The oral care composition of claim 10 , wherein the surfactant comprises sodium lauryl sulfate, cocamidopropyl betaine, or combinations thereof.
