Abstract

An encapsulated oral care composition includes: (a) a gelatin capsule; and (b) a oral care composition contained within the capsule, and including: (i) a hydrophilic active; (ii) a hydrophobic structuring agent; and (iii) an oil carrier. The hydrophilic active is preferably cetylpyridinium chloride. The hydrophobic structuring agent is preferably a gelled mineral oil. The oil carrier is preferably a vegetable oil. A method of cleaning teeth includes applying to the teeth the encapsulated oral care composition such that the capsule releases the oral care composition to clean the teeth. A oral care implement includes: a handle; a head mounted to the handle, the head having an outer surface and a plurality of tooth cleaning elements extending outwardly from the outer surface; and the encapsulated oral care composition positioned on the head.

Claims (23)

1. An encapsulated oral care composition comprising:

(a) a water soluble capsule; and

(b) an oral care composition contained within the capsule, and comprising:

i. a hydrophilic active;

ii. a hydrophobic structuring agent; and

iii. a hydrophobic carrier;

wherein the hydrophobic structuring agent comprises a gelled mineral oil and is present in an amount of 1-20 wt. % based on a total weight of the oral care composition; and

wherein the hydrophilic active is cetylpyridinium chloride, and wherein the gelled mineral oil comprises polyethylene and mineral oil.

2. The composition of claim 1 , wherein the hydrophilic active comprises a solid active.

3. The composition of claim 1 , wherein the carrier comprises at least one of a vegetable oil and silicone oil.

4. The composition of claim 1 , wherein the carrier comprises a C6 to C12 triglyceride.

5. The composition of claim 1 , wherein the carrier constitutes 60-80 wt. % of the oral care composition.

6. The composition of claim 1 , wherein the hydrophilic active constitutes 0.05-5 wt. % of the oral care composition.

7. The composition of claim 1 , wherein the oral care composition further comprises 5-25 wt. % of a flavoring agent and 0.1-5 wt. % of a sweetening agent.

8. The composition of claim 1 , wherein the carrier is caprylic/capric triglyceride and the oral care composition further comprises hydrated silica, sorbitol, sucralose, glycerin, a colorant and a flavoring agent.

9. The composition of claim 1 , wherein the oral care composition has a viscosity from 150 to 750 cps as measured by a Brookfield LVDV 2+ with V73 spindle at 1 rpm.

10. A oral care implement 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 the composition of any preceding claim positioned on the head.

11. The composition of claim 2 , wherein the carrier constitutes 60-80 wt. % of the oral care composition.

12. The composition of claim 11 , wherein the carrier comprises at least one of a vegetable oil and silicone oil.

13. The composition of claim 12 , wherein the composition has a particle settling time of more than 10 minutes.

14. The composition of claim 13 , wherein the cetylpyridinium chloride constitutes 0.05-5 wt. % of the oral care composition, the carrier is caprylic/capric triglyceride, and the oral care composition further comprises hydrated silica, sorbitol, sucralose, glycerin, a colorant and a flavoring agent.

15. The composition of claim 13 , wherein the cetylpyridinium chloride constitutes 0.05-5 wt. % of the oral care composition, and the carrier is caprylic/capric triglyceride.

16. The composition of claim 15 , wherein the oral care composition has a viscosity from 150 to 750 cps as measured by a Brookfield LVDV 2+ with V73 spindle at 1 rpm.
