A razor blade cartridge including at least one razor blade and a housing made from a polymer material and comprising an outer surface wherein at least part of the outer surface of the housing is coated with a hydrophilic material, and wherein the outer surface of the housing comprises undulations on at least a portion of the coated part.
A razor blade cartridge including at least one razor blade and a housing made from a polymer material and comprising an outer surface wherein at least part of the outer surface of the housing is coated with a hydrophilic material, and wherein the coating is formed from an acrylamide.
A method of manufacture of a razor blade cartridge comprising the steps of:
- providing a cartridge housing including undulated skin contacting surfaces of polymeric material;
- activating the undulated skin engaging surfaces of the polymer using either physical or chemical means to make the undulated surface receptive to the covalent grafting of a monomer:
- and then grafting a functional group onto the surface.
