Abstract

Disclosed are oral compositions containing phosphocitrate to provide improved anticalculus activity.

Claims

1. An oral composition comprising:

(a) a safe and effective amount of a phosphocitrate material; and

(b) an acceptable mouthwash carrier for topical application in the mouth.

2. A composition according to claim 1 wherein the phosphocitrate material is selected from the group consisting of phosphocitrate, water soluble salts of phosphocitrate, short chain esters of phosphocitrate and mixtures thereof.

3. A composition according to claim 2 wherein the phosphocitrate material is selected from the group consisting of phosphocitrate, water soluble salts of phosphocitrate and mixtures thereof.

4. A composition according to claim 3 which in addition contains a soluble fluoride ion source.

5. A composition according to claim 4 which in addition contains a nonphosphocitrate anticalculus agent.

6. A composition according to claim 1 wherein the additional anticalculus agent is selected from the group consisting of metal ions, soluble pyrophosphate salts, polycarboxylic acids, polyphosphonates and mixtures thereof.

7. A composition according to claim 4 which is in the form of a mouthwash.

8. A method of reducing calculus by contacting the dental enamel surfaces in the mouth of a human or lower animal having the propensity to form calculus with a safe and effective amount of a composition according to claim 1.

9. A method according to claim 8 wherein said composition contains one or more additional anticalculus agents.
