The present invention relates to a tooth whitening component delivery system that is water soluble prior to application to a tooth, but forms an insoluble film in water by in situ gelling on the oral tooth surface. And a second agent containing a water-soluble alginate, and a first agent comprising a peroxide and silica, and a substance for improving tooth adhesion is contained in at least one of the first agent and the second agent. system; Alternatively, one agent comprising a water insoluble calcium ion source, a peroxide, and silica, and an acid and a water soluble alginate capable of meeting the calcium ion of one agent to release water-soluble calcium ions. It is composed of two agents containing soluble alginate, and the liquid tooth whitening component delivery system is characterized in that the substance for improving tooth adhesion is contained in at least one of the first agent and the second agent. Since the adhesive holding force is excellent, it is suitable for the case where a sufficient contact time is required to obtain a desired whitening effect with short term use. |
