  • Patent number: 4663152
    Abstract: 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 dentifrice 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.
