FUNCTIONAL AGGLOMERATED SPECKLES, METHOD FOR MANUFACTURE THEREOF AND DENTIFRICES CONTAINING SUCH SPECKLES ABSTRACT OF THE DISCLOSURE: Functional agglomerated speckles, for incorporation in dentifrices, include agglomerates of a water insoluble powdered functional material and water insoluble, ethanol soluble ethyl cellulose. Such speckles satisfactorily maintain their integrity and identity during processing of the dentifrice after addition of the speckles to the main dentifrice body but on storage, after packaging of the dentifrice in dispensing tubes, soften sufficiently so as to become essentially impalpable to one utilizing the denti- frice in brushing his teeth. Despite such softening the speckles continue to maintain their identity as speckles in the dentifrice. The speckles are especially useful in translucent or transparent gel dentifrices which contain components, such as flavoring and surface active agents, which may controllably soften the speckles on storage. Also described in the specification are methods for the manufacture of the mentioned speckles, dentifrices incorporating them, methods for manufacturing such dentifrices and such denti- frices packaged in end use dispensing containers.
