  • Patent number: 6265052
    Abstract: A wiping implement suitable for use as a bath tissue can be formed into sheets, each sheet comprising at least one ply of a paper web having a basis weight of at least about 25 lb/3000 square feet. The sheet can have a width of at least about 4.5 inches and temporary wet tensile properties. The sheet of the present invention can have an area of at least about 30 square inches. In a multiple ply embodiment, the sheet can have an optimized basis weight of at least about 42 lb/3000 square feet while maintaining nearly the same amount of actual total fiber usage per cleaning task as current premium bath tissues.

  • Patent number: 6238682
    Abstract: An anhydrous lotion composition for killing viruses and bacteria in addition to imparting a soft, lubricious, lotion-like feel when applied to tissue paper and tissue paper treated with such lotion compositions are disclosed. The antiviral action of the lotion is due to the addition of an organic acid such as citric acid or salicylic acid. The antibacterial action is due to the addition of antibacterial agents such as TRICLOSAN®. The solubilization of the antiviral and antibacterial agents within the lotion matrix is aided by the addition of hydrophilic solvents and hydrophilic surfactants. The lubricious lotions also contain a plastic or fluid skin conditioning agent such as petrolatum, an optional immobilizing agent such as a fatty alcohol or fatty acid to immobilize the skin conditioning agent on the surface of the tissue paper web and a hydrophilic surfactant to improve wettability when applied to toilet tissue.

  • Patent number: 5902669
    Abstract: Disposable paper products, such as paper toweling, are provided with an indicator means which is disposed on said disposable paper product in a discontinuous or combination discontinuous/continuous pattern. The indicator means gives a visually recognizable signal to a user that desirable properties of the disposable paper product are maintained, even after the disposable paper product has become wetted with a substantially transparent aqueous liquid. The wet gray scale difference for the disposable paper product of the present invention is at least about 64 gray scale units when the disposable paper product is wetted with a substantially transparent aqueous liquid.
