Abstract: A deodorant composition for topical application, which comprises a plurality of particles dispersed and a carrier, each particle comprising a glass microsphere at least partially coated with zinc oxide, a zinc salt, or any mixture of two or more thereof.

Abstract: A battery includes a housing, an anode in the housing, a cathode in the housing, and a separator between the cathode and the anode. The housing has a surface adjacent to the cathode. The surface defines an opening, such as an elongated opening, adapted to facilitate a generally non-circular flux of gas on a portion of the cathode. The battery can provide relatively high current density and relatively high capacity.

Abstract: A suspension of a pigment in a grease is used as a ballpoint penink.

Abstract: Pressure generating gas-releasing compositions which are microcmulsions, siloxane or hydrocarbon greases or elastomers, are used to aid dispensation of a fluid from a reservoir without the composition itself being dispensed. Dispensers containing such compositions can include writing implements.

Abstract: Disclosed is a method of coating cutting edges, more particularly razor blade cutting edges, with polytetrafluoroethylene (PTFE). The present method of forming a polytetrafluoroethylene (PTFE) coating on a razor blade cutting edge comprises: spraying the edge of an aqueous dispersion of PTFE having a molecular weight of at least 500,000 to form a coating of the PTFE of the cutting edge; subjecting the PTFE coating to ionizing radiation in the presence of an oxygen containing gas to obtain a radiation dose of up to 50 Mrads, and then sintering the PTFE coating.

Abstract: A correction fluid containing a composite that includes particles composed of a film-forming polymer, and a polymeric material.

Abstract: A three-component mouthrinse comprises a mouthrinse active material e.g. bactericide, a polymeric material e.g. polysaccharide which can be gelled in the mouth, and means (e.g. a polyacid) for gelling the polymeric material to form a water-insoluble gel in the mouth, from which gel the active material is slowly released.

Abstract: A water-insoluble porous cross-linked polymeric matrix contains an antiperspirant in its pores, the pores being interconnected to permit the antiperspirant to be leached therefrom with water, with zero order release without change in pore geometry. The pores may additionally contain one or more other materials such as deodorants, moisturizers, lubricants and perfumes. The matrix can be shaped for application to the skin. An antiperspirant dispenser can comprise a matrix of the invention with a water reservoir therefor.

Abstract: A hand-held correction or marking material (20) comprises a solid synthetic matrix (26) containing a correction or marking material. The matrix is such that when it is drawn over and in contact with a paper or similar surface, it deposits thereon as a thin dry coating which is immediately hard. The matrix can liquify temporarily in the contact area and then immediately resolidify in the form of the thin coating. The correction materials comprise an opacifier such as titanium dioxide, and the marking materials comprise a colored pigment or dye in the matrix.
