  • Patent number: 5977054
    Abstract: Disclosed are mildly acidic liquid compositions for use in cleaning hard surfaces. The compositions contain from about 1% to about 60% of an amine oxide detergent surfactant, an aqueous carrier liquid, and an acidifying agent having a pK.sub.a of less than about 6.0. The compositions contain enough of the acidifying agent to protonate at least about 10% of the amine oxide species within the compositions and to provide a composition pH of between about 3 and 7. These no-rinse liquid hard surface cleaning compositions have excellent cleaning properties, they do not leave a visible residue when they dry, and they cause minimal or no staining of vinyl surfaces. Also disclosed are a method for cleaning vinyl surfaces using the liquid compositions, and non-liquid compositions from which the mildly acidic liquid compositions can easily be obtained by adding an aqueous liquid.

  • Patent number: 5968029
    Abstract: The present invention is directed to a macroscopically three-dimensional formed substrate including a first boundary zone having a first surface pathlength and a second boundary zone having a second surface pathlength. The first and the second surface pathlengths are preferably measured when the formed substrate is in a relaxed condition. The substrate also includes an elongated zone located at least partially between the first boundary zone and the second boundary zone. The elongated zone comprises incrementally stretched regions which result in the elongated zone being elongated in a first direction of elongation and having a third surface pathlength measured when the formed substrate is in the relaxed condition. The third surface pathlength is greater than either the first pathlength or the second pathlength such that the substrate takes on a macroscopic three-dimensional configuration when the backsheet is in a relaxed condition.
