Abstract
Abstract An aqueous oral preparation is provided which contains a peroxygen compound and a flavor which is stable in such system. The peroxygen compound is preferably hydrogen peroxide. The preparation may be in the form of a mouthrinse, a paste or a gel. Many optional ingredients may be included such as ethanol, polyhydric alcohols, non-ionic surfactants, fluorides, color, preservative, sweetener, and the like. A preferred rinse includes ethanol, sorbitol, a Pluronic surfactant, a Tween surfactant, sodium saccharin, and color. A typically preferred gel is similar to the rinse but contains about 20 wt. % of a thickener.
