Abstract:
An oral care composition for activating a peroxidase system in an animal oral cavity, comprising:a non-aqueous or otherwise substantially water-free dentifrice; a non-enzymatic, water-soluble, finely divided hydrogen peroxide precursor material incorporated within the dentifrice, the material capable of rapidly releasing an effective amount of hydrogen peroxide for activating the peroxidase system in the oral cavity upon contact with an aqueous solution, the material coated or encapsulated by being dispersed in a water insoluble, non-hygroscopic, viscous fluid or in a film-forming, melt-processable waxy solid, the fluid or solid selected from the group consisting of: (a) liquid mineral oils, vegetable oils, fatty esters, silicone fluids, fluorinated hydrocarbons and fluorosilicones, or (b) solid mineral oils, vegetable oils, fatty esters, silicone fluids, fluorinated hydrocarbons, fluorosilicones, stearic acid, glycerin monosterate, paraffin wax, microcrystalline wax, and fatty alcohols the fluid or solid being a non-solvent of the material; and a pH-adjusting agent capable of producing a selected pH of between about 4.0 and about 6.5 in the aqueous solution.
