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.
Claims19
A process for providing a lubricating shaving aid on a razor cartridge, the process comprising the steps of:
- (a) immersing a material in an aqueous dispersion comprising water, a water soluble component in solution, and a dispersion of a water insoluble component dispersed in said water and said solution of said water soluble component for a time sufficient to permit said dispersion to be deposited onto said material;
- (b) removing said material with the deposited dispersion thereon;
- and
- (c) drying said deposited dispersion to form said shaving aid, said resulting shaving aid being structured to permit uniform release of said water insoluble component as said water soluble component dissolves upon exposure of said shaving aid to water.
A process for forming a lubricating shaving aid, the process comprising the steps of:
- forming an aqueous dispersion comprising water, a water soluble component in solution, and a dispersion of a water insoluble component dispersed in said water and said solution of said water soluble component;
- depositing a layer of said aqueous dispersion on a substance;
- and
- drying said deposited dispersion to form said shaving aid, said resulting shaving aid being structured to permit uniform release of said water insoluble component as said water soluble component dissolves upon exposure of said shaving aid to water.
