Document Type and Number:
WIPO Patent Application WO2005018884
Kind Code:
A3
Abstract:
A shaving aid delivery material for use in a shaving implement comprises at least one layer of binder material having a plurality of microspheres embedded therein. Each of the microspheres defines an interior area containing shaving aid that may be applied to a user's skin surface. During a shaving operation, at least a portion of the microspheres degrade to release the shaving aids from the interior area onto the skin surface. Multiple shaving aid layers containing binder material and microspheres may be laminated together, and may further include additional film or barrier layers separating the shaving aid layers.
