Abstract:
Described herein are tooth whitening strips comprising an hydratable adhesive film having a granular bleaching ingredient attached thereto, wherein upon hydration, the granular bleaching ingredient releases hydrogen peroxide which is used by an enzyme catalyst having perhydrolytic activity to enzymatically produce an effective amount of peracid bleaching agent from an acyl donor substrate. Methods of making and use the tooth whitening strips are also provided.
Abstract:
A peroxide containing dual component dentifrice composition providing enhanced whitening efficacy and minimal gingival irritation and tooth sensitivity, the composition being comprised of a separately maintained first aqueous dentifrice component containing a peroxide compound and an abrasive system compatible with the peroxide and a second aqueous dentifrice component containing a desensitizing compound and an abrasive that is incompatible with peroxide compound whereby when the components are mixed and combined for the first time and exposed to the surface of teeth, an enhanced whitening effect is obtained with minimal tooth sensitivity and gum irritation.
Abstract:
Described herein are tooth whitening strips comprising a hydratable adhesive film with a first side and a second side, the first side having a granular bleaching ingredient attached thereto in an amount effective to whiten teeth, together with methods of making and using the same.
Abstract:
Oral care compositions containing: a free-B-ring flavonoid and a flavan; as well as at least one bioavailability-enhancing agent are provided. Methods of using the oral compositions are also provided.
Abstract:
Described herein are packages for storing and dispensing multi-part tooth whitening formulations, wherein the contents of the parts are mixed, a peracid and/or dioxirane whitening agent is formed. Particular multi-part tooth whitening formulations using this principle and methods of use thereof are also provided.
Abstract:
Described herein are packages for storing and dispensing multi-part tooth whitening formulations, comprising a deformable material configured to form two or more sealed chambers, e.g., wherein the first chamber contains a low viscosity liquid solution comprising an enzyme having perhydrolytic activity, and the second chamber contains a peroxide source and a at least one acyl donor substrate. Particular multi-part tooth whitening formulations using this principle and methods of use thereof are also provided.
Abstract:
An oral composition comprising a vehicle and a zinc ion source in the form of nanoparticles that are substantially non-aggregated and methods for use of such compositions are described. The composition provides antiplaque and anti malodor benefits to the user and the inclusion of nanoparticles permits a reduction in the amount of zinc ions present in the composition while maintaining efficacy.
Abstract:
Tooth-whitening films comprising a hydratable polymer and a whitening agent are disclosed in which the films have a hydrophobic coating on one surface and a tooth-adherent coating on the opposing surface. Flavorings can also be included in the hydratable polymer portion of the film or in either the hydrophobic coating or the tooth-adherent coating. Tooth-whitening methods that use the films are also disclosed. The hydratable polymer preferably is a polyethylene oxide.
