Abstract

See full text

A shaving unit that comprises at least one blade and a shaving composite has a surface for engaging the user's skin adjacent the blade edge. The shaving unit may be of a disposable cartridge type adapted for coupling to and uncoupling from a razor handle or may be integral with a handle so that the complete razor is discarded as a unit when the blade or blades become dulled. The blade edge (or edges) cooperate with skin engaging surfaces to define shaving geometry. The skin-engaging surface includes a shaving aid composite that is a mixture of water insoluble matrix material, an effective amount of shaving aid material, and an effective amount of water-insoluble essential oil material, the water-insoluble essential oil material being delivered from the shaving aid composite concurrently with the delivery of the water-leachable shaving aid material during shaving to apply at least about one nanogram of the essential oil to the skin surface per square centimeter of skin surface.
