Benefits of technology
[0006] A peroxide product is provided. The peroxide product includes a package having a headspace, a substrate disposed within the package, and a thin layer of a composition having a peroxide active and a polyol, wherein the thin layer is disposed adjacent the substrate. The peroxide product also includes at least one means for increasing the stability of the peroxide active of the composition. The thin layer of the composition has at least about 43% of its original concentration of the peroxide active at twelve months after manufacture when stored at about 25° C. and in the absence of light.
Problems solved by technology
It is known that tooth whitening active materials may be difficult to keep stable for long periods of time.
However, the peroxide containing oral composition is more difficult to stabilize for extended periods of time because the oral composition is stored as a thin layer and not in a syringe or in bulk.
