ABSTRACT:
An extrudable composite multilayer dentifrice composition for cleaning teeth containing reactive bicarbonate and peroxide ingredients which do not interact during storage or when extruded together from a container onto a toothbrush but react in the oral cavity when mixed during tooth brushing, the composition comprising two separate dentifrice components, one component containing a peroxide ingredient and the other component containing a colorant reactive with the peroxide ingredient, the components having substantially equivalent viscosity which are maintained in stable discrete layered phases in interfacial contact with each other prior to extrusion without interaction of the peroxide and the colorant and which are extrudable together in interfacial contact without interaction of the ingredients.
