SEMI-OPAQUE TEETH WHITENING PATCH

摘要

PURPOSE: A dry type patch for whitening teeth using a hydrophilic glass polymer as a substrate, together with a peroxide stabilizer as a whitening agent on a matrix type adhesive layer is provided. Because the patch is neither stick to hands or a body, nor noticed by other people when used, it is conveniently used and has an excellent teeth whitening effect. CONSTITUTION: The matrix type patch for adhesion of tooth enamel contains an adhesive layer and a backing layer, wherein the adhesive layer contains a hydrophilic glass polymer as a substrate and peroxide and a peroxide stabilizer as a teeth whitening agent. Hydration of the hydrophilic glass polymer by moisture on the surface of teeth causes strong adhesion and releases the teeth whitening agent at the same time. The patch additionally contains condensed phosphate to improve the whitening effect.
