J 7030 ABSTRACT Toothpaste Composition Packaged toothpaste formulations which contain air sensitive components, e.g. vitamin C, are prevented from discolouring or otherwise degrading, by placing adjacent to an area of the packaging which may allow air access to the formulation, e.g. an air permeable collar, a nozzle, or the wall of an air permeable tube, a body (e.g. plug or layer) of material which does not contain any air sensitive components. Preferably, the latter body of material is the packaged toothpaste but without the air sensitive components.
