Publication number: 20130295526Abstract: 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.Type: ApplicationFiled: July 5, 2013Publication date: November 7, 2013Applicant: ORAL HEALTH CLINICAL SERVICES, LLCInventor: Salim A.

Patent number: 7833539Abstract: This invention relates generally to compositions for whitening human teeth, and more particularly, to compositions that do not contain hydrocarbon humectants and which, when applied onto the surface of teeth act to whiten without damage to tooth surfaces. They do contain a hydrogel, defined as a gel that does not contain a hydrocarbon humectant. A hydrocarbon humectant is defined as a carbon, hydrogen and oxygen compound which is used to prevent the oral care composition from hardening upon exposure to air or a carbon, hydrogen and oxygen compound which is used as a carrier for ingredients of an oral care composition.Type: GrantFiled: June 7, 2004Date of Patent: November 16, 2010Assignee: Oral Health Clinical Services, LLCInventor: Salim A.
