  • Patent number: 9603360
    Abstract: A disposable paper towel with an anti-microbial lotion and is provided with a chromatic transfer indicator which undergoes a delayed, visually perceptible color change at a predetermined time after the towel is wetted. An anti-microbial lotion on the towel increases water absorbency times (WAR) to further promote lotion transfer to the skin and increase lotion transfer effectiveness.

  • Patent number: 7638475
    Abstract: A cleaning system having pulverulent foaming cleanser (e.g., acid, alkali metal carbonate and surfactant) is sealed within a water soluble (e.g., PVOH) deformable pouch frictionally retainable within the core of a roll of bath tissue. Upon placement of the pouch in the bowl, water in the bowl penetrates the water soluble wall of the pouch, generating foam which provides cleaning action by activating and carrying cleansing chemicals, not only below the water line of the bowl, but also considerably above it. When used routinely with each change of bath tissue roll, such a cleaning can extend the time between required manual cleanings considerably.
