Beschreibung
Zusammenfassung:	Functional agglomerated speckles, for incorporation in dentifrices, include agglomerates of a water insoluble powdered functional material and water insoluble, ethanol soluble ethyl cellulose, and may sometimes preferably also include a water soluble binder, such as polyvinyl pyrrolidone. These speckles are formed into a stream, which is directed on to a stream of a dental composition so that the speckles are insufficient to cover the stream of the dental composition, whereby the 2 streams are adhered together to produce a dentifrice.
