High cleaning dentifrice compositions
A dentifrice composition containing minor amounts of relatively small particle size high cleaning abrasives, without oral care actives. The dentifrice may be encapsulated and optionally, positioned on the head of a toothbrush. Use of the dentifrice provides a small amount of high cleaning abrasive to the teeth, and has stain removal efficacy. In one aspect, a dentifrice composition comprising an orally acceptable carrier and 1 to 10 wt % abrasive, such that the total amount of abrasive delivered per application is 2 mg to 8 mg, the abrasive having a weight mean particle size in the range of 3 to 7 μm, with at least 90% of the particles by weight having a size below 16 μm, and wherein the composition does not contain an oral care active.
1. A toothbrush comprising:
a handle;
a head mounted to the handle, the head comprising an outer surface and a plurality of tooth cleaning elements extending outwardly from the outer surface; and
a dentifrice composition positioned on the head, wherein the dentifrice composition comprises an orally acceptable carrier and 1 to 10 wt % abrasive, such that the total amount of abrasive delivered per application is 2 mg to 8 mg, the abrasive having a weight mean particle size in the range of 3 to 7 μm, with at least 90% of the particles by weight having a size below 16 μm, and wherein the composition does not contain antibacterial agents, malodor prevention agents, anti-caries agents, whitening agents, tartar control agents, foaming agents, anti-calculus agents, fluorides, anti-microbial agents, or anti-inflammatory agents,
wherein the orally acceptable carrier comprises a triglyceride.
2. The toothbrush of claim 1 , wherein the total amount of abrasive delivered per application is 3 to 6 mg.
3. The toothbrush of claim 1 , wherein the dentifrice composition further comprises 5% to 25% by weight of a flavoring material and 0.1% to 5% by weight of a sweetening agent.
4. The toothbrush of claim 1 , wherein the dentifrice composition comprises about 75 weight % triglyceride, about 15 weight % flavor, about 5 weight % of the abrasive, about 0.5 weight % sweetener, and about 4.5 weight % ethanol.
5. The toothbrush of claim 1 , wherein the dentifrice is encapsulated.
6. The toothbrush of claim 5 , wherein the dentifrice is encapsulated in gelatin.
7. The toothbrush of claim 1 further comprising a dispenser positioned within the cleaning elements, the dispenser containing the dentifrice composition.
8. The toothbrush of claim 7 , wherein the dispenser is a capsule and the dentifrice composition is encapsulated within the capsule in liquid form.
9. The toothbrush of claim 1 , wherein the cleaning elements are constructed of an elastomeric material.
10. The toothbrush of claim 1 , wherein the dentifrice composition is encapsulated within a gelatin capsule, the gelatin capsule positioned within and surrounded by the cleaning elements, wherein the cleaning elements are elastomeric.
11. The toothbrush of claim 1 , wherein the cleaning elements comprise the dentifrice composition.
12. An encapsulated dentifrice composition suitable for use with the toothbrush of claim 1 , comprising an orally acceptable carrier and 1 to 10 wt % abrasive, the dentifrice comprising 2 mg to 8 mg of abrasive, the abrasive having a weight mean particle size in the range of 3 to 7 μm, with at least 90% of the particles by weight having a size below 16 μm, wherein the composition does not contain antibacterial agents, malodor prevention agents, anti-caries agents, whitening agents, tartar control agents, foaming agents, anti-calculus agents, fluorides, anti-microbial agents or anti-inflammatory agents, and wherein the orally acceptable carrier comprises a triglyceride.
13. The dentifrice of claim 12 , comprising 3 to 6 mg of abrasive.
14. The dentifrice of claim 12 , wherein the dentifrice composition further comprises 5% to 25% by weight of a flavoring material and 0.1% to 5% by weight of a sweetening agent.
15. The dentifrice of claim 12 , wherein the dentifrice composition comprises about 75 weight % triglyceride, about 15 weight % flavor, about 5 weight % of the abrasive, about 0.5 weight % sweetener, and about 4.5 weight % ethanol.
16. The dentifrice of claim 12 , wherein the dentifrice is encapsulated in gelatin.
17. A method of making a dentifrice composition comprising mixing an orally acceptable carrier, flavors, sweeteners, and optionally, a processing aid to form a liquid mixture, and adding to the liquid mixture 1 to 10 wt % abrasive having a mean particle size in the range of 3 to 7 μm, with at least 90% of the particles by weight having a size below 16 μm, without mixing or adding antibacterial agents, malodor prevention agents, anti-caries agents, whitening agents, tartar control agents, foaming agents, anti-calculus agents, fluorides, anti-microbial agents or anti-inflammatory agents, the method further comprising encapsulating the dentifrice composition in a gelatin capsule, wherein the dentifrice comprises 2 mg to 8 mg of the abrasive, and wherein the orally acceptable carrier comprises a triglyceride.
18. An encapsulated dentifrice composition, prepared in accordance with the method of claim 17 .
19. A method of removing stain from teeth comprising applying a dentifrice composition to the teeth in a manner that delivers 2 mg to 8 mg of an abrasive to the teeth, wherein the dentifrice composition comprises an orally acceptable carrier and 1 to 10 wt % abrasive, the abrasive having a weight mean particle size in the range of 3 to 7 μm, with at least 90% of the particles by weight having a size below 16 μm, wherein the composition does not contain antibacterial agents, malodor prevention agents, anti-caries agents, whitening agents, tartar control agents, foaming agents, anti-calculus agents, fluorides, anti-microbial agents or anti-inflammatory agents, and wherein the orally acceptable carrier comprises a triglyceride.
20. The method of claim 19 , wherein the total amount of abrasive delivered per application is 3 to 6 mg.
21. The method of claim 19 , wherein the dentifrice further comprises 5% to 25% by weight of a flavoring material and 0.1% to 5% by weight of a sweetening agent.
22. The method of claim 19 , wherein the dentifrice composition comprises about 75 weight % triglyceride, about 15 weight % flavor, about 5 weight % of the abrasive, about 0.5 weight % sweetener, and about 4.5 weight % ethanol.
