Abstract
A cartridge including a housing, at least one blade having a blade tip, and a shaving aid positioned on said housing and having a skin contacting portion. The shaving aid includes a co-axial filament having a diameter of from about 0 nm to about 1000 nm and has a core and a sheath. Also disclosed is a method of making a shaving aid for use on a razor including: extruding a shaving aid through a die to form an extruded shaving aid, in which the shaving aid has a skin contacting surface; and electrospinning at least two components to form a co-axial nano-filament onto a portion of the skin contacting surface to form a coated shaving aid, in which the two components are immiscible.
