Oral care compositions
Described herein are oral care compositions, comprising a peroxydone complex, a dispersant, and a polyvinylpyrrolidone copolymer structure-building agent.
1. A non-aqueous oral care composition consisting of:
from about 0.01% to about 60% of peroxydone complex, based on a total weight of the oral care composition;
from about 0.01% to about 60% of an amphiphilic copolymer structure-building agent, based on the total weight of the oral care composition; and
from about 0.01% to about 99% of a non-aqueous liquid dispersant comprising propylene glycol diacetate, based on the total weight of the oral care composition;
a fluoride ion source;
optionally, a phosphate;
optionally, a thickening agent;
optionally, a pH modifying agent;
optionally, an anticalculus, a tartar control agent, or a combination thereof;
optionally, an abrasive;
optionally, a humectant;
optionally, a surfactant;
optionally, a sweetener, a flavorant, or a combination thereof,
optionally, a colorant, a dye, a pigment, or a combination thereof.
2. The non-aqueous oral care composition of claim 1 , wherein the amphiphilic copolymer is a polyvinylpyrolidone vinyl acetate copolymer.
3. The non-aqueous oral care composition of claim 1 , wherein the non-aqueous liquid dispersant further comprises one or more of the group consisting of glycerin monoacetate, triacetin, diethylene glycol diacetate, ethylene glycol diacetate, and a combination of two or more thereof.
4. The non-aqueous oral care composition of claim 2 , wherein the oral care composition has a mass ratio of the polyvinylpyrrolidone vinyl acetate copolymer to the non-aqueous liquid dispersant of from 30:70 to 40:60.
5. The oral care composition of claim 1 , wherein the peroxydone complex includes a crosslinked polyvinylpyrrolidone complexed with hydrogen peroxide (PVP-H202).
6. The oral care composition of claim 5 , wherein the polyvinylpyrrolidone copolymer is a polyvinylpyrrolidone vinyl acetate copolymer.
7. The oral care composition of claim 1 , wherein the non-aqueous liquid dispersant further comprises a liquid poloxamer or a paste poloxamer.
8. The oral care composition of claim 7 , wherein the liquid poloxamer comprises polyoxyethylene-polyoxypropylene glycol.
9. The oral care composition of claim 1 , wherein the non-aqueous liquid dispersant further comprises triacetin.
10. The oral care composition of claim 1 , wherein the non-aqueous liquid dispersant has a logP value of from about −2.0 to about 2.0.
11. The oral care composition of claim 1 , wherein a viscosity of the oral care composition is from about 50,000 to about 500,000 cPs.
12. The oral care composition of claim 1 , wherein the oral care composition is a dentifrice.
