  • Wet wipe with non-aqueous, oil-based solvent for industrial cleaning
    Patent number: 6136775
    Abstract: An absorbent wipe is provided impregnated with a non-toxic, oil-based cleaning solvent comprising the polar oil d-limonene, a non-polar mineral oil, and a hydrophilic surfactant. The resulting article provides an effective wipe for removing oil-based soils such as oil, grease, tar, ink, and similar contaminants. The article provides a non-toxic wipe which is safe for use on skin, has low volatility, and provides a solvent which self-emulsifies in water. Accordingly, the solvent residue may be easily rinsed and removed from cleaned surfaces. Further, the solvent carrying the removed contaminant may be separated from the wiper to facilitate hazardous waste separation.

  • Indented coreless rolls and method of making the same
    Patent number: 5875985
    Abstract: A coreless roll of product that is self-supporting in a rotary dispenser. The roll includes a rolled web of product that is wound throughout its diameter about a winding axis into a cylinder having first and second flat ends. At least one flat end defines a mounting hole at substantially the center of the winding axis of the coreless roll. The mounting hole has a depth and has sides generally perpendicular to the end of the roll. The sides are separated by a distance that is less than the depth of the hole such that the mounting hole is adapted to receive a plunger from a rotary dispenser. Methods of making the coreless roll are also described.
