Abstract

The present invention provides mouthwash or mouthrinse compositions comprising one or more structuring agents selected from: a colloidal gum, a cellulosic polymer, an acrylate polymer, or a clay or fine particulate, and an orally acceptable aqueous carrier. In some embodiments, the total concentration of the one or more structuring agents is less than 5%, by weight, of the composition.

First claim

What is claimed is:

1. A fluid composition comprising:
structuring agents consisting of:
a colloidal gum;
a cellulosic polymer;
an acrylate polymer; and
a clay or fine particulate; and
an orally acceptable aqueous carrier;

wherein the total concentration of the structuring agents is from about 0.03% to about 2%, by weight, of the composition;
wherein the composition is a mouthwash or mouthrinse,
wherein the composition has a Flow Rate Index from about 0.1 to about 0.85, a Consistency Index of from about 10 to about 2000 and a G′/G″ ratio of 1 to 15;
wherein the colloidal gum comprises is xanthan gum in an amount of from about 0.01 to about 0.5%, by weight; and wherein the clay or fine particulate is selected from calcium magnesium silicate or amorphous silica, and is present in a concentration of 0.5%, by weight;
wherein the cellulosic polymer comprises is carboxymethyl cellulose in an amount of from about 0.01 to about 0.5%, by weight; and
wherein the acrylate polymer is present in an amount of from about 0.01 to about 0.5%, by weight.

2. The composition of claim 1 , further comprising a humectant selected from: sorbitol, glycerin, propylene glycol, ethanol, or a combination of two or more thereof.

3. The composition of claim 1 , wherein the orally acceptable aqueous carrier comprises greater than 50%, by weight, free water.

4. The composition of claim 1 , further comprising one or more components selected from a fluoride ion source; a tartar control agent; a buffering agent; an abrasive; or a combination of two or more thereof.

5. The composition of claim 4 , wherein the fluoride ion source is selected from: stannous fluoride, sodium fluoride, potassium fluoride, sodium monofluorophosphate, sodium fluorosilicate, ammonium fluorosilicate, amine fluoride, ammonium fluoride, or a combination of two or more thereof.

6. The composition of claim 1 , wherein the structuring agents consist of:
from about 0.03 to about 0.1%, by weight, of xanthan gum;
from about 0.02 to about 0.1%, by weight, of carboxymethyl cellulose;
from about 0.03 to about 0.1%, by weight, of an acrylate polymer; and 0.5%, by weight of clay or fine particulate.

7. The composition of claim 1 , further comprising a suspended material.

8. The composition of claim 7 , wherein said suspended material is selected from: a colloidal metal; a film flake; a film strip; or a combination of two or more thereof.

9. The composition of claim 2 , wherein the orally acceptable aqueous carrier comprises greater than 50%, by weight, free water.

10. The composition of claim 9 , wherein the structuring agents consist of:
from about 0 . 03 to about 0 . 1 %, by weight, of xanthan gum;
from about 0 . 02 to about 0 . 1 %, by weight, of carboxymethyl cellulose; and
from about 0 . 03 to about 0 . 1 %, by weight, of an acrylate polymer; and 0.5%, by weight of clay or fine particulate.

11. The composition of claim 10 , further comprising one or more components selected from a fluoride ion source; a tartar control agent; a buffering agent; an abrasive; or a combination of two or more thereof.

12. The composition of claim 11 , wherein the fluoride ion source is selected from: stannous fluoride, sodium fluoride, potassium fluoride, sodium monofluorophosphate, sodium fluorosilicate, ammonium fluorosilicate, amine fluoride, ammonium fluoride, or a combination of two or more thereof.
