  • Publication number: 20240123642
    Abstract: Razors cartridges including a guard, a cap, and at least two blades with parallel sharpened edges located between the guard and cap are provided. The first blade has a first color and a second blade has a second color, where the first color is different than the second color. The blade color corresponds to an attribute of the blade (e.g., low cut force) that the color is disposed on or an attribute of the razor cartridge (e.g., sensitive skin). The color of the blade corresponds to a target user of the razor cartridge (e.g., male or female). The first blade defines a blade edge near or nearest the guard and a second blade defines a blade edge near or nearest the cap.

  • Patent number: 8481010
    Abstract: The present invention relates generally to the field of primers and adhesion promoters. More specifically, the primer of the present invention is comprised of one or more multi-carbonylated methacrylates. In a preferred embodiment, a non-ketone polar solvent is also employed. The resulting composition eliminates primer related discoloration of artificial nail enhancements, eliminates the potential for corrosion of skin and nails, and eliminates risk of chemical burn injury, while providing stronger adhesion than currently available primers.
