Abstract
A shaving unit comprises at least one blade and a shaving composite that 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 shaving aid composite is a mixture of water insoluble matrix material, an effective amount of shaving aid material, and a water soluble low molecular weight release enhancing agent that enhances the releasability of the shaving aid material from the matrix material.
