Abstract: A wet shaving system is disclosed including a blade member and a skin-engaging portion in proximity to said blade member, the skin-engaging portion comprising a solid polymeric shaving aid composite including an exposed portion containing a water-soluble shaving aid dispersed in a water-insoluble polymeric matrix, the water soluble shaving aid being coated with mineral oil.

Abstract: The invention discloses a novel geometry for a lubricating body, strip or cap, composed of shaving aids, taking into consideration their shape, materials and placement along with their interaction with multiple blades for improved shaving attributes in a wet shaving system. A strip exposure and a strip angle is disclosed where generally a maximum height of the lubricating strip is greater than or equal to the maximum height of the blade plane.

Abstract: A shaving unit includes a composite that has a surface for engaging the user's skin. The composite includes adjacent lengthwise-extending portions, each containing a shaving aid.

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: The present invention relates to razor blade cutting edges which exhibit an improvement in the first shave. Conventional razor blade cutting edges exhibit surprisingly high initial cutting forces. Razor blades produced according to the present process exhibit significantly lower initial cutting forces which correlates with a more comfortable first shave. Improved blades according to the present invention involve treating conventional razor blade cutting edges having an adherent polyfluorocarbon coating with a solvent to partially remove some of the coating. Preferred solvents include perfluoroalkanes, perfluorocycloalkanes, perfluoropolyethers having a critical temperature or boiling point above the dissolution temperature for the polyfluorocarbon in the solvent. The present invention also relates to the method of producing these razor blade cutting edges.

Abstract: A finger-manipulated article (e.g., a pen) includes a foam grip. The foam preferably is made from a foamable polyurethane prepolymer and a filler, or a latex, or both. The preferred foam has a recovery rate of less than 5 cm per minute. The foam may include a surface coating on its outer surface.
