Abstract

An oral care kit comprising an oral care implement having a first reservoir containing a first oral care agent comprising a first whitening reagent that includes triacetin; and a container having a second reservoir containing a second oral care agent, the second oral care agent comprising a catalytic enzyme and a second whitening reagent that includes peroxide forming compound.

Claims (24)

1. An oral care implement comprising:

a body comprising a handle, a head at an end of the handle, and at least one fluid outlet, the head having at least one oral care element extending therefrom;

a reservoir in the body containing an oral care agent comprising a whitening reagent, the whitening reagent consisting of triacetin;

wherein the reservoir is in fluid communication with the fluid outlet.

2. The oral care implement according to claim 1 , wherein the oral care agent is substantially free of a peroxide source.

3. The oral care implement according to claim 1 , wherein the whitening reagent is present in an amount ranging from 10 ppm to about 1000 ppm.

4. The oral care implement according to claim 1 , wherein the oral care agent further comprises an orally acceptable carrier in an amount ranging from about 10 ppm to about 1000 ppm.

5. The oral care implement according to claim 1 , wherein the fluid outlet is located on the head.

6. An oral care kit comprising

an oral care implement having a first reservoir containing a first oral care agent comprising a first whitening reagent that includes triacetin; and

a container having a second reservoir containing a second oral care agent, the second oral care agent comprising a catalytic enzyme and a second whitening reagent that includes peroxide forming compound.

7. The oral care kit according to claim 6 , wherein the first whitening reagent consists of triacetin.

8. The oral care kit according to claim 6 , wherein the first oral care agent is substantially free of a peroxide source.

9. The oral care kit according to claim 6 , wherein the first whitening reagent is present in an amount ranging from about 10 ppm to about 1000 ppm based on the total weight of the first oral care agent.

10. The oral care kit according to claim 6 , wherein the second whitening reagent comprises hydrogen peroxide.

11. The oral care kit according to claim 6 , wherein the second whitening reagent is present in an amount ranging from about 10 ppm to about 1000 ppm.

12. The oral care kit according to claim 6 , wherein the catalytic enzyme is present in an amount ranging from about 0.01 wt. % to about 1 wt. % based on the total weight of the second oral care agent.

13. The oral care kit according to claim 6 , wherein the oral care implement is a toothbrush, wherein the container is a toothpaste container and the second oral care agent is dentifrice.

14. A method of whitening teeth comprising

applying a second oral care agent to a head of an oral care implement, the oral care implement comprising a reservoir containing a first oral care agent comprising triacetin;

cleaning an oral cavity with the head of the oral care implement as the first oral care agent is delivered to a fluid outlet on the head from the reservoir,

wherein the second oral care agent comprises a peroxide source and a catalytic enzyme.

15. The method according to claim 14 , wherein the triacetin is present in an amount ranging from about 10 ppm to about 1000 ppm upon delivery.

16. The method according to claim 14 , wherein the catalytic enzyme is present in an amount ranging from about 0.001 wt. % to about 1 wt. % based on the total weight of the second oral care agent.
