long-term rheological stability tooth whitening compositions and devices, kits and methods using such compositions |
| abstract |
long-term rheological stability tooth whitening compositions and devices, kits and methods using such compositions. Tooth whitening compositions include a tooth whitening agent, and a polyvinylpyrrolidone (pvp) tissue adhering agent and / or generally linear, high molecular weight polyethylene (peo) oxide, ie greater than about 500,000 contained in a an amount that confers a high level of adhesion, a rheology modifying agent such as fumigated silica or fumigated alumina that reduces or eliminates the fiber otherwise caused by high molecular weight pvp and / or powder and a solvent or carrier. Dental whitening compositions may include carboxypolymethylene in place of or in addition to pvp and / or pe, where fumigated silica or fumigated alumina enhances long-term rheological stability even in the presence of a high concentration of tooth whitening agent. dental treatment devices (100) including a barrier layer (101) and an amount of the tooth whitening composition (112) are positioned adjacent the barrier layer (101). |
