Abstract: The present invention embraces an anhydrous topical antiperspirant or deodorant composition comprising an antiperspirant or deodorant active, a dermatologically acceptable volatile silicone liquid carrier vehicle and a polyethylene homopolymer dissolved in the vehicle to serve as a thickening or solidifying agent, wherein the polyethylene homopolymer has a molecular weight of about 200 to about 800 daltons, preferably about 300 to about 600 daltons, most preferably about 400 to about 500 daltons. The composition should be substantially free of any other organic or natural waxes. The present invention also embraces a method of inhibiting or reducing perspiration or a method of inhibiting or reducing malodor by topically applying an effective amount of such an antiperspirant composition or deodorant composition to the skin.

Abstract: The present invention is directed to a solid polymeric shaving aid strip for a razor cartridge. The shaving aid strip comprises a lubricious water-soluble polymer and a polycaprolactone, and optionally a water-insoluble polymer. It has been found that polycaprolactone improves the fabrication of the shaving aid strip, provides smoother strip surfaces and permits the inclusion of greater amounts of water-soluble polymer in the strip. It has also been found that a shaving aid strip which contains polycaprolactone releases more shaving aid during use and has better structural integrity and less swelling. The present invention is also directed to a razor cartridge which includes the aforementioned shaving aid strip.

Abstract: The present invention is directed to a razor cartridge with a solid polymeric shaving aid strip. The razor cartridge has a blade (one or more) and a skin-engaging portion in proximity to the blade. The skin-engaging portion includes a solid polymeric shaving aid strip having an upper exposed surface which contacts the skin during shaving. The shaving aid strip includes a first exposed lengthwise-extending portion containing a lubricious water-soluble polymer and an adjacent, second exposed lengthwise-extending portion containing a lubricious water-soluble polymer. The first portion contains a greater amount of the lubricious water-soluble polymer than the second portion, and the first portion is adapted to wear at a faster rate than the second portion during shaving. This construction enables the strip to release more of the lubricious water-soluble polymer for a longer time period (i.e., for more shaves) than conventional shaving aid strips.

Abstract: This relates to an improved skin engaging member for use in razor blade; cartridge assemblies and shaving systems of the wet shave type. In an embodiment, there is provided a two-component, control-release shaving device consisting of(a) a sheath layer made from thermoplastic resins with openings therein and (b) a core region containing internal shaving aids. Potentially, the device can maintain surface appearance, control-release the shaving aids, minimize the degradation of the shaving aids, and prevent the shaving aids from being trapping in a strip. Furthermore, the addition of low-melt additives to the shaving aids becomes feasible and the compatibility between the shaving aids and the shaving aid carrier such as polystyrene in the lubricating strip composite becomes less critical.

The present invention also embraces an apparatus for delivering the above-described composition, said apparatus having a porous dome with a porosity of about 150&mgr; to 400&mgr; through which the composition is delivered.

Abstract: The present invention provides an after shave composition comprising, by weight, 30 to 98%, preferably 65 to 95%, most preferably 70 to 90%, water, 0 to 65%, preferably 0 to 25%, most preferably 10 to 22%, ethanol, 0.25 to 6%, preferably 1 to 5%, fragrance, 0.25 to 5%, preferably 1 to 4%, surfactant to solubilize or emulsify the fragrance, and 0.5 to 1.5% (U.S.P.), preferably 0.8 to 1.3%, aluminum chlorohydrate. Preferably, the composition will be a clear solution or microemulsion having a clarity better than 100 NTU and a viscosity less than 200 mPas. The foregoing composition provides, upon application to the skin, reduced stinging and burning, reduced redness and irritation, and a soothing effect without tackiness or other undesirable aesthetic attributes.

Abstract: A dispenser for fluid material comprising a cylindrical container with a metering device disposed therein. The container comprises a dispensing end and a closed end, while the metering device forms a dispensing cavity separated from a storage cavity at the dispensing end of the container and a metering cavity formed at the closed end of the container. Movement of the container to a position with the closed end disposed downwardly and then to a position with the dispensing end disposed downwardly is effective to cause fluid to flow from the storage cavity into the metering cavity and be metered in a desired quantity into the dispensing cavity.

Abstract: An improved self-foaming shaving gel is provided which includes water, a water-soluble soap component, and a self-foaming agent, plus a hydrogenated polyisobutene in combination with a fluorosurfactant.

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: The present invention relates to methods of making enhanced efficacy antiperspirant salts and particularly stabilized aqueous polyhydric alcohol solutions of such salts.
