    • 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 a 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.
    • 本发明涉及含有过氧化物作为牙齿增白剂的干式牙齿增白贴剂。 特别地,公开了在基质型粘合剂层中含有作为牙齿增白剂的过氧化物的干式牙齿增白贴剂。 粘合剂层包括作为其基础聚合物的亲水性玻璃聚合物,其在湿润口腔中的牙齿的牙釉质层上水合时释放牙齿增白剂,同时提供对牙齿的强粘附性。 与湿式贴剂相比,本发明的干型贴剂使用方便。 此外,它表现出优异的粘附性,同时保持在附着于牙齿的状态下延长一段时间,以确保贴剂中的增白剂和牙齿上的污渍之间的足够的接触时间,从而产生足够的美白效果 。
