Claim Text:
1. An effective amount of non-agitated effervescent oral care foam, the foam comprising: a non-agitated combination of a first component containing an acid; and a second component containing an alkaline source of equal to or less than about 2%; wherein one or both of the first and second components also contains a surfactant and a foam stabilizer to thicken the component, the foam stabilizer including at least the thickener hydroxyethyl cellulose and the foam stabilizer also optionally including one or more low viscosity thickeners and mixtures thereof to assist in maintaining the foam half-life; wherein the first and second components are structurally disposed to be combined and spontaneously form a substantial, non-agitated effective amount of effervescing oral care foam chemically outside the mouth with a half-life of foam of at least about 5 minutes and up to about 17-20 minutes without any mechanical mixing or agitation added, the effective amount being that amount to provide the give said half-life; wherein said first component further comprises at least one peroxide compound in an aqueous solution and at least one peroxide stabilizer in the form of an ion scavenger; said second component comprises at least one foaming agent and at least one peroxide activator, wherein said activator is disposed to promote the rapid decomposition of the peroxide compound and additional foaming action not related to the foaming agent; and the final pH of the combination of the first and second components is between about 6 and 6.5.
