Abstract
A whitening composition and methods for whitening teeth and generating a whitening agent with the same are provided. The whitening composition may include an orally acceptable vehicle, a source of hydrogen peroxide that provides hydrogen peroxide, and a cyclic anhydride that generates a whitening agent with the hydrogen peroxided provided by the source of hydrogen peroxide. The whitening agent may be a peracid, such as a succinic peracid.
Claims14
A mouthwash composition, comprising an orally acceptable vehicle, sodium carbonate, a source of hydrogen peroxide that provides hydrogen peroxide, and a cyclic anhydride that generates a peracid with the hydrogen peroxide provided by the source of hydrogen peroxide;
- and
- wherein the molar ratio of the cyclic anhydride to the hydrogen peroxide provided by the source of hydrogen peroxide is from about 0.8:1 to about 1.3:1;
- wherein the orally acceptable vehicle further comprises one or more ingredient selected from antibacterial agents, anticalculus agents, humectants, surfactants and cooling agents;
- and
- wherein the cyclic anhydride is not a polymer-based cyclic anhydride.
A method for generating a whitening agent in a mouthwash composition, comprising contacting a cyclic anhydride and hydrogen peroxide with one another in the presence of sodium carbonate, wherein the whitening agent is a peracid;
- and
- wherein the cyclic anhydride is not a polymer-based cyclic anhydride.
