Abstract: Stable topical oral compositions comprising at least a minimally effective amount of chlorite ion are disclosed, wherein the pH of the final composition is greater than 7, the composition is essentially free of chlorine dioxide, and the composition is stable against loss of chlorite for a period of at least one year under normal storage conditions at about 25° C. or for a period of 3 months under accelerated storage conditions at about 40° C. Preferably the compositions further comprise a flavor system, which is stable against degradation by chlorite. The compositions are formulated as therapeutic rinses, especially mouth rinses, as well as toothpastes, gels, tooth powders, chewing gums, mouth sprays, lozenges (including breath mints), dental implements (such as dental floss and tape), and pet care products.

Abstract: Disclosed are oral care compositions and methods for overall cleaning, whitening and preventing, reducing or removing surface deposited stains on natural teeth and dental prosthesis, the compositions comprising in an orally acceptable carrier at least 0.1% by weight of a water-soluble or water-dispersible copolymer prepared by copolymerizing one or a mixture of vinyl pyrrolidone (VP) monomers with one or a mixture of C1-C19 alkyl carboxylic acid (AC) C2-C12 alkenyl ester monomers. Preferably, the compositions further comprise one or a mixture of other oral care agents selected from a water soluble alkali metal or ammonium tripolyphosphate in an amount at least about 0.5% by weight of the composition, an abrasive, preferably a precipitated silica abrasive, in an amount at least about 6% by weight of the composition and a bleaching agent in an amount at least about 0.1% by weight of the composition.
