| 20090208543 | METHOD AND APPARATUS FOR APPLYING A PROTECTIVE ORAL CARE COMPOSITION - Compositions and methods for whitening human teeth containing peroxide and a hydroperoxidase inhibitor. The compositions exhibit superior teeth whitening effects while also retaining a greater amount of peroxide compared to compositions not containing the hydroperoxidase inhibitors. The compositions may be formulated in a hydrocarbon humectant free vehicle comprising a peroxide compound, a hydroperoxidase inhibitor, a chelating agent, an anti-oxidizing agent, and a thickening agent. The compositions may further include compounds to reduce oxidative stress. Also disclosed is a delivery system including a flexible film, an oral care composition that contacts the teeth, an adhesive material that generally contacts the soft tissues, and a physical barrier that prevents contact between the oral care composition and the adhesive material. | 08-20-2009 |
