ABSTRACT:

BACKGROUND OF INVENTION
A recognized consumer need is a low cost commercial oral care delivery system that is comfortable to wear that can deliver a sufficient amount of an oral care substance for rapid delivery of an active contained in such substance. In addition a delivery system is needed which does not require extensive user placement manipulation to be certain of good contact for optimal delivery. Furthermore, what is needed is a non-bulky active containment means that will permit the wearer to use the system during social discourse without interfering with the wearer's speech or appearance. Also needed is a containment means that will protect oral care substance from erosion from contact with other oral surfaces and, or saliva.
SUMMARY OF INVENTION
Delivery systems for whitening teeth are provided. The delivery systems include a strip of material sized to cover a front surface of a plurality of teeth and a layer of a tooth whitening substance in contact with the strip of material. The tooth whitening substance includes a gelling agent and a whitening active selected from the group consisting of peroxides, metal chlorites, perborates, percarbonates, peroxyacids, hypochlorites, and combinations thereof. The delivery systems further include a release liner having a coating thereon, wherein the release liner exhibits less affinity for the tooth whitening substance than the tooth whitening substance exhibits for itself and for the strip of material.
