  • Patent number: 8802062
    Abstract: Disclosed herein is a pair of dry type patches for teeth whitening, having a patch for upper teeth and a patch for lower teeth, in which the patch for upper teeth has a shape different from the patch for lower teeth, and each patch has a controlled width and shape such that the contact area of each patch with gums is minimized. In the patch for upper teeth, a central portion covering right and left upper central incisors is widest. In the patch for lower teeth, either portion covering right and left lower canine teeth is widest. Since the dry type patches covers all the portions of the teeth while minimizing the contact area with gums, no or little irritation is caused and wearability is excellent.

  • Patent number: 8647607
    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.

  • Patent number: 7785572
    Abstract: A dry type adhesive device for teeth whitening in which a peroxide tooth whitening agent is stabilized is disclosed. The dry type adhesive device for tooth whitening comprises a matrix type adhesive layer and a backing layer wherein the adhesive layer contains a peroxide as a teeth whitening agent and a hydrophilic glassy polymer as a base polymer so that the hydrophilic glassy polymer provides strong adhesion to teeth when hydrated at the enamel layer of the teeth in the moist oral cavity and the whitening agent is released. In particular, although the dry type adhesive device is touched with the hands or contact the skin during attaching to the teeth prior to hydration, no stickiness and releasing of the whitening agent takes place, thus being safe.

  • Publication number: 20080219935
    Abstract: Disclosed herein is a breath freshener whose phase is changed depending on the condition of use. A breath freshener of W/O emulsion phase comprises a monoglyceride as a main base, a polymer, an effective component for breath freshening, and a solvent. A breath freshener of solution phase comprises a monoglyceride as a main base, a polyol, a polymer, an effective component for breath freshening, and a solvent. Since the breath fresheners are sufficiently flowable to spray when being sprayed into the oral cavity, they are easy to use. In addition, the breath fresheners are phase-changed into a cubic phase by moisture, e.g., saliva, after being sprayed into the oral cavity, resulting in an increase in the viscosity and adhesiveness of the breath fresheners. Therefore, the effective breath freshening ingredient is slowly released from the breath fresheners, and as a result, continuous breath freshening effects are achieved.

  • Publication number: 20080193392
    Abstract: Disclosed herein is a tooth whitener using glycerol monooleate. The tooth whitener is a composition that exhibits teeth whitening effects when being applied to teeth. Specifically, the tooth whitener comprises a glycerol monooleate, a polyol, a polymer, a peroxide and a hydrophilic solvent, and has a W/O emulsion phase. The tooth whitener is flowable before being applied to teeth and is spreadable when being applied to teeth. In addition, the tooth whitener is solidified by the action of moisture, such as saliva, after being applied to teeth, and can thus be adhered and fixed to the teeth. Further-more, changes in viscosity of the tooth whitener with varying temperature can he minimized and the release rate of the whitening ingredient can he controlled by the addition of polyol.

  • Patent number: 6946142
    Abstract: The present invention relates to a dry type teeth whitening patch with a multi-layer structure of three or more layers. More particularly, in the dry type patch, a contact adhesive layer substantially free of peroxide comprises a hydrophilic glass polymer as a base polymer so that it provides substantial adhesive strength when hydrated by water, an active material reservoir layer comprises peroxide as a teeth whitening agent, and a backing layer which is impermeable to water. The dry type patch of the present invention has superior teeth whitening effect and excellent peroxide stability at a high temperature since the peroxide-containing layer is covered and protected by other layers.
