Abstract

Described herein are oral care compositions comprising a surfactant system; a structuring agent, and a lipophilic agent; and methods of making and using the same.

First claim

What is claimed is:

1. A foaming oral care composition for enhancing flavor comprising:
a surfactant system comprising:
an anionic surfactant comprising sodium lauryl sulfate present in an amount of about 0.5 to about 3%, by weight;
a zwitterionic surfactant comprising cocamidopropyl betaine in an amount of about 0.2 to about 3%, by weight; and
a nonionic surfactant comprising poloxamer 407 in an amount of about 1 to about 3%, by weight;

a structuring agent which is xanthan gum in an amount of 0.85%, by weight;
a lipophilic agent comprising a mixture of flavor components in an amount of about 1 to about 3%, by weight;
tetrasodium pyrophosphate; and
from 24% to 32%, by weight, free water,
a fluoride ion source selected from: stannous fluoride, sodium fluoride, potassium fluoride, sodium monofluorophosphate, sodium fluoro silicate, ammonium fluorosilicate, amine fluoride, ammonium fluoride, and a combination of two or more thereof,
wherein the composition does not contain a cellulose colloidal polymer and wherein the composition is a single phase toothpaste.

2. The composition of claim 1 wherein the lipophilic agent has a partition coefficient (octane-water) with an overall log P value of greater than about 1.5.

3. The composition of claim 1 , comprising:
about 1.5%, by weight, of an anionic surfactant;
about 0.75%, by weight, of a zwitterionic surfactant;
about 2%, by weight, of a nonionic surfactant;
0.85%, by weight, of a structuring agent;
about 1.5%, by weight, of a lipophilic agent; and
about 28%, by weight, free water.

4. The composition of claim 1 wherein the lipophilic agent, surfactant system and aqueous components are capable of forming an emulsion.

5. The composition of claim 1 , wherein said foam comprises a matrix containing said lipophilic agent.

6. The composition of claim 1 , wherein said foam has a volume greater than about 100 mL.

7. A method of improving the delivery of a lipophilic agent to the oral cavity comprising contacting an oral cavity surface of a subject in need thereof with a composition according to claim 1 .

8. The composition of claim 1 , wherein the fluoride ion source comprises sodium fluoride.

9. The composition of claim 1 , further comprising a silica abrasive.

10. The composition of claim 1 , wherein the tetrasodium pyrophosphate is present in an amount of about 0.5% by weight.
