  • Patent number: 4443564
    Abstract: Functional agglomerated speckles, for incorporation in dentifrices, include agglomerates of a water insoluble powdered functional material and a mixture of a water insoluble, ethanol soluble ethyl cellulose binder and a suitable water soluble binder, such as polyvinyl pyrrolidone. Such speckles, while more "soluble" or disintegrable in a flavored dentifrice than those based on ethyl cellulose binders without PVP, still can 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, they will soften sufficiently so as then to be essentially impalpable to one utilizing the dentifrice in brushing his teeth. Despite such softening the speckles continue to maintain their identity as separate small bodies in the dentifrice.
    Type: Grant
    Filed: August 30, 1982
    Date of Patent: April 17, 1984
    Assignee: Colgate-Palmolive Company
