Abstract: A disposable electrode comprising an annulus of foam, a substantially uniform electrode gel in a central region of the annulus, a conductive layer in the electrode gel and making electrical contact with it, and a cap over the conductive layer, electrode gel and annulus of foam. The electrode is made in a plastic tray by placing said annulus in a recess in the tray, placing the conductive layer on the annulus, pouring hot electrode gel into the center region of the annulus, covering the gel with the cap and covering the tray with a sheet whcih is heat sealed to the tray with the electrode inside.

Abstract: An improved gel comprises a first polymer that dissolves, disperses or hydrates in hot water and forms or can be made to form a rigid gel on cooling, a second polymer that is insoluble in hot water and that dissolves or hydrates on cooling and is compatible with said hot water soluble polymer, and water. The gel is made by combining the first polymer and water, heating the resulting solution enough that the first polymer dissolves or hydrates, adding the hot water insoluble polymer, and then cooling.

Abstract: This invention relates to a novel astringent antiperspirant aerosol system which comprises an astringent salt suspended in fine powder form in an anhydrous liquid vehicle and a propellant.
