US Patent No. 8,496,947 B2; Creative Specialty Products, LLC, Lewes, DE, has patented a dental whitening strip that has a three layer laminated structure. The first layer is a barrier support comprising a polyolefin polymer film in contact with a second and middle layer which is a whitening composition, which adheres to the barrier support. The whitening composition comprises a dried layer that is formed from a whitening composition comprising dextrin, peroxide, a non-toxic water soluble inorganic salt, a pharmaceutically acceptable hydroxy compound which is a plasticizer and water so it can be adhered to a third layer, which is the carrier layer. The whitening layer is dried so that it does not flow, does not wet objects and has retained volatiles between 7 and 17% as determined by drying in an oven at 170°F. for one hour.
