  • Patent number: 6861048
    Abstract: A method for reducing an abrasivity of a dentifrice composition containing an abrasive, includes incorporating into the dentifrice composition a zinc salt in an amount sufficient to reduce a dentinal abrasivity of the composition by at least 10% and reduce an enamel abrasivity of the dentifrice composition by at least 10%. The method provides an improved dentifrice composition, which is at least 90% as effective at stain removal as the original dentifrice composition. Suitable zinc salts include, e.g., zinc citrate, zinc chloride, zinc acetate, zinc oxide and zinc sulfate. Suitable abrasives include, e.g., silica, alumina and alkali metal meta-phosphates.

  • Patent number: 6689344
    Abstract: The present invention relates to a dry type tooth-whitening patch comprising peroxide as a tooth whitening agent. In particular, disclosed is a dry type tooth-whitening patch in which peroxide is contained, as a teeth whitening agent, in a matrix type adhesive layer. The adhesive layer includes, as a base polymer thereof, a hydrophilic glass polymer, which provides a strong adhesion to teeth while releasing the tooth whitening agent when hydrated on the enamel layers of teeth in the moist oral cavity. The dry type patch according to the present invention is convenient in use, as compared to wet type patches. Further, it exhibits a superior adhesion while being maintained in a state attached to the teeth for a lengthened period of time so as to assure an enough contact time between the whitening agent in the patch and stains on the teeth, thereby giving a sufficient whitening effect.
