Abstract
The present invention is directed to a lubricating shaving aid on a shaving razor or a shaving cartridge to reduce frictional drag between a razor blade edge and a shaver's skin and to provide a lubricating film on the shaver's skin during wet shaving. The lubricating shaving aid comprises a water soluble component and a water insoluble component and is formed such that the water insoluble component is released as the water soluble component dissolves upon exposure to water. The invention further discloses a method for making the same from an aqueous dispersion of water, a water soluble component in solution, and a dispersion of a water insoluble component dispersed in the water and the solution of the water soluble component.
