The present invention is directed to a solid polymeric shaving aid strip (22) for a razor cartridge (14). The shaving aid strip (22) 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 (14) which includes the aforementioned shaving aid strip.
Cette invention concerne une barrette d'aide au rasage (22) en polymère plein destiné à une cartouche de rasoir. Cette barrette (22) comprend un polymère lubrifiant hydrosoluble et une polycaprolactone avec, éventuellement un polymère hydrosoluble. On a constaté que le polycaprolactone permettait d'améliorer la fabrication de la barrette d'aide au rasage, d'obtenir des surfaces plus lisses pour ladite barrette et d'inclure dans cette dernière des quantités plus importantes de polymère hydrosoluble. De plus, Il est apparu qu'une barrette d'aide au rasage renfermant du polycaprolactone libérait davantage d'auxiliaire de rasage pendant l'emploi et possédait une meilleure intégrité structurale, pour un moindre gonflement. La présente invention concerne également une cartouche de rasoir (14) qui renferme la barrette d'aide au rasage susmentionnée.
