DUAL COMPONENT DENTAL COMPOSITION CONTAINING ENZYME

摘要

A method for providing an oral care composition containing enzymes without substantial denaturation of the enzyme which comprising: preparing (1) a first dentifrice component containing the enzyme in an orally acceptable aqueous vehicle which is substantially free of ionic surfactant and (2) a second dentifrice component containing an ionic surfactant in an orally acceptable aqueous vehicle which is substantially free of enzyme, separately housing the first and second components, dispensing the first and second components simultaneously, combining the dispensed components and thereafter applying the combined components to teeth whereby the enzyme activity is substantially retained during application to the teeth, wherein the oral care composition does not contain an antibacterial agent in either component and wherein the first dentifrice component and the second dentifrice component have substantially equivalent rheologies.
