Wet shaving system including a mineral oil coated shaving aid
View Patent ↗A wet shaving system is disclosed including a blade member and a skin-engaging portion in proximity to said blade member, the skin-engaging portion comprising a solid polymeric shaving aid composite including an exposed portion containing a water-soluble shaving aid dispersed in a water-insoluble polymeric matrix, the water soluble shaving aid being coated with mineral oil.
1. A method of manufacturing a shaving aid composite comprising:
spray coating a water-soluble shaving aid with mineral oil;
mixing the water-soluble shaving aid with a water-insoluble polymer; and
forming the mixture into a solid shaving aid composite shaped to be retained by a receiving portion of a razor cartridge,
wherein said step of coating is performed prior to said step of mixing,
wherein the mineral oil is present in a concentration of about 2% to about 6% based on the total weight of the water soluble shaving aid,
wherein all of the water-soluble shaving aid is coated with mineral oil, and
wherein the water-soluble shaving aid consists of polyethylene oxide.
2. The method of claim 1 wherein the forming step comprises extrusion.
3. The method of claim 1 wherein the forming step comprises injection molding.
4. The method of claim 1 wherein the forming step comprises forming a base layer having a first composition and forming an upper portion, and a surface layer having a second composition, and wherein the step of forming the mixture into a solid shaving aid composite comprises placing the surface layer upon the upper portion of the base layer.
5. The method of claim 4 wherein the second composition has a relatively higher concentration of mineral oil than the second composition.
6. The method of claim 4 wherein the base layer and surface layer have different colors.
