Stable peroxide containing personal care compositions

Abstract

The present invention relates to stable personal care composition, including oral care compositions containing a peroxide source. The compositions are stabilized by eliminating or minimizing the presence in the composition of metals having radical forming potential with the peroxide. Preferably, the metals that are eliminated or reduced are cobalt, copper, palladium, nickel and iron. The compositions are further stabilized by the addition of agents having scavenging or quenching activity for free radicals. Reducing free radical activity in the product matrix prevents radical-mediated loss and degradation of peroxide and other ingredients, in particular organic compounds added as active or aesthetic agents, including flavors, perfumes, colorants and thickeners. Provided are peroxide containing oral care products with enhanced consumer appeal in terms of taste, mouthfeel and appearance, thereby encouraging compliance and regular use. Such attributes are important since use of these products may involve fairly long residence time in the mouth for efficacy.
