Oral care compositions

1. A method of cleaning the oral cavity comprising: a) introducing into the oral cavity a composition having a first viscosity of less than 2000 centipoise at a shear rate of 10 s −1 , and a tan delta of less than 1 at frequencies 0.1 to 100 rads −1 , and comprising a surfactant system comprising at least one nonionic, at least one anionic, and at least one amphoteric surfactant; from about 0.05% to about 1% of a suspending agent comprising high acyl gellan gum, a combination of high acyl gellan gum and xanthan gum, or a combination of microcrystalline cellulose, carboxymethylcellulose, and xanthan gum; and at least 45% of an orally acceptable liquid carrier; and b) swishing the composition in the oral cavity.

2. The method of 1 further comprising the step of: c) after the swishing step b), brushing teeth having at least a portion of the composition in contact therewith with a toothbrush.

3. The method of claim 1 wherein said composition is shear-thinning.

4. The method of claim 1 wherein said composition comprises a total surfactant amount of from about 0.1 to about 5% based on the total weight of the composition.

5. The method of claim 1 wherein the composition further has a second viscosity of less than about 1000 centipoise at a shear rate of 100 s −1 .

6. The method of claim 1 wherein said composition further comprises an insoluble particulate.

7. The method of claim 6 wherein said insoluble particulate comprises silica.

8. A method of cleaning the oral cavity comprising: a) introducing into the oral cavity a composition having a first viscosity of less than 2000 centipoise at a shear rate of 10 s −1 , and a tan delta of less than 1 at frequencies 0.1 to 100 rads −1 , and comprising a surfactant system comprising at least one nonionic, at least one anionic, and at least one amphoteric surfactant; from about 0.05% to about 1% a suspending agent comprising high acyl gellan gum, a combination of high acyl gellan gum and xanthan gum, or a combination of microcrystalline cellulose, carboxymethylcellulose, and xanthan gum; a non-abrasive particulate containing an encompassed material selected from the group consisting of oral care actives, vitamins, pigments, dyes, antimicrobial agents, chelating agents, optical brighteners, flavors, perfumes, humectants, and mixtures thereof; and at least 45% of an orally acceptable liquid carrier, b) swishing the composition in the oral cavity to coat one or more surfaces of the oral cavity with said composition; and c) brushing said one or more surfaces of the oral cavity coated with said composition to shear one or more of said non-abrasive particulates containing an encompassed material within said composition.

9. The method of claim 8 wherein said non-abrasive particulate contains a flavor that is released upon brushing step c).

10. The method of claim 8 wherein said non-abrasive particulate contains a pigment or dye that is released upon brushing step c).

11. The method of claim 8 wherein said non-abrasive particulate contains an oral care active that is released upon brushing step c).
